How does a rotary vane vacuum pump work?

Oil sealed rotary vane vacuum pump working principle

A rotary vane vacuum pump (referred to as a rotary vane pump) is an oil-sealed mechanical vacuum pump. Its working pressure range is 101325~1.33×10-2 (Pa), which belongs to the low vacuum pump. It can be used alone or as a backing pump for other high vacuum pumps or ultra-high vacuum pumps. It has been widely used in production and scientific research departments such as metallurgy, machinery, military industry, electronics, chemical industry, light industry, petroleum, and medicine.

The rotary vane pump can pump out the dry gas in the sealed container, and if it is equipped with a gas ballast device, it can also pump out a certain amount of condensable gas. But it is not suitable for pumping gas with high oxygen content, corrosive to metal, and chemical reactions to pump oil and dust particles.

The rotary vane pump is one of the most basic vacuum-obtaining equipment in vacuum technology. Rotary vane pumps are mostly small and medium-sized pumps. There are two types of rotary vane pumps: single-stage and two-stage. The so-called two-stage is to connect two single-stage pumps in a series structure. Generally, it is made into two stages to obtain a higher vacuum degree. The relationship between the pumping speed and the inlet pressure of the rotary vane pump is stipulated as follows: when the inlet pressure is 1333Pa, 1.33Pa, and 1.33×10-1 (Pa), the pumping speed value shall not be lower than 95%, 50% and 20%of the nominal pumping speed of the pump.

The rotary vane pump is mainly composed of the pump body, rotor, rotary vane, end cover, spring, and so on. A rotor is eccentrically installed in the cavity of the rotary vane pump, the outer circle of the rotor is tangent to the inner surface of the pump cavity (there is a small gap between the two), and two rotary vanes with springs are installed in the rotor slot. When rotating, relying on the centrifugal force and the tension of the spring to keep the top of the rotary vane in contact with the inner wall of the pump chamber, the rotation of the rotor drives the rotary vane to slide along the inner wall of the pump chamber.

The two rotating vanes divide the crescent-shaped space surrounded by the rotor, the pump chamber, and the two end covers into three parts A, B, and C, as shown in the figure. When the rotor rotates in the direction of the arrow, the volume of space A communicating with the suction port increases gradually, and it is in the process of suction. And the volume of space C communicating with the exhaust port is gradually reduced, just in the process of exhausting. The volume of space B in the middle is also gradually decreasing, which is in the process of compression. Since the volume of space A gradually increases (that is, expands), the gas pressure decreases, and the external gas pressure at the inlet of the pump is higher than the pressure in space A, so the gas is inhaled.

When space A is isolated from the suction port, it turns to the position of space B, the gas starts to be compressed, the volume gradually decreases, and finally communicates with the exhaust port. When the compressed gas exceeds the exhaust pressure, the exhaust valve is pushed open by the compressed gas, and the gas passes through the oil layer in the tank and is discharged into the atmosphere. The purpose of continuous pumping is achieved by the continuous operation of the pump.

One stage rotary vane vacuum pump working principle 

The single-stage rotary vane pump has only one working chamber, and the pump is mainly composed of a stator, a rotary vane, and a rotor. The rotor is installed eccentrically in the pump chamber, and two rotating vanes are installed in the rotor groove, which is close to the cylinder wall due to the elastic force of the spring (there is also a centrifugal force of the rotating vanes after rotation). The rotor and vanes divide the stator cavity into suction and discharge.

When the rotor rotates in the stator cavity, the volume on the side of the air inlet is gradually expanded periodically to inhale the gas, while the volume on the side of the exhaust port is gradually reduced to compress the inhaled gas and discharge it from the exhaust valve.

The vent valve is immersed in oil to prevent atmospheric air from entering the pump. The vacuum pump oil enters the pump chamber through the oil hole and the exhaust valve so that all the moving surfaces in the pump chamber are covered with oil, forming a seal between the suction chamber and the exhaust chamber.

Two stage rotary vane vacuum pump working principle 

In order to improve the ultimate vacuum of the pump, in addition to improving the machining accuracy of the pump body, rotor, and rotary vane, and minimizing the assembly gap and harmful space, the most effective way is to connect two single-stage pumps in series to form a two-stage pump.

The pump consists of two working chambers. The two chambers are connected in series and rotate in the same direction at the same speed. A chamber is the front stage of B chamber. A is the low vacuum stage and B is the high vacuum stage. The pumped gas enters the front stage through the high vacuum stage (B ), and is discharged out of the pump through the exhaust valve. The front stage (A) is the same as the single-stage pump, oil enters the pump chamber at any time, while the high vacuum stage (B) only has a small amount of oil when it starts to work, and no oil enters the pump chamber after working for a period of time. When the pump starts to work and the pressure of the inhaled gas is relatively high (such as starting to pump air from atmospheric pressure), the gas is compressed through the B chamber, and the pressure increases sharply, and a part of the compressed gas is directly discharged from the auxiliary exhaust valve (1) , and the other part is discharged through the front stage.

When the pump works for a period of time, when the pressure of the gas inhaled by the B chamber is low, even though it is compressed by the B chamber, the pressure cannot reach above one atmospheric pressure, and the auxiliary exhaust valve 1 cannot be discharged, and all the inhaled gas will enter The front-stage A room is discharged through the exhaust valve 3 through the continuous compression of the A room.

After the pump works for a period of time since the pressure of the high-vacuum stage air intake is greatly reduced, the outlet pressure is also very small, so the pressure difference between the inlet and outlet of the B chamber is also small, and the amount of compressed gas returned is correspondingly reduced; at the same time, the latter stage The oil molecules that are easy to evaporate in the pump are continuously sucked away by the front-stage A chamber, and the partial pressure of the oil vapor is reduced. Therefore, the oil pollution of the two-stage pump is smaller than that of the single-stage pump, and the ultimate vacuum degree will be greatly improved.

1 Stage vs. 2 Stage Rotary Vane Vacuum Pump

1 stage rotary vane pump consists of a single rotor with multiple vanes that rotates within a cylindrical chamber. As the rotor spins, centrifugal force pushes the vanes against the chamber wall, creating a seal and forming variable-volume chambers. The pumping action occurs through the expansion and compression of gas in these chambers, resulting in the generation of a vacuum.

Simplicity: 1-stage pumps have a straightforward design with fewer moving parts, making them compact, lightweight, and easy to operate and maintain.

Cost-Effective: These pumps are typically more affordable compared to 2-stage pumps, making them a cost-effective option for applications that do not require extremely low vacuum levels.

Suitable for Low to Medium Vacuum: 1-stage pumps are ideal for applications that require vacuum levels within the range of approximately 100 to 1,000 mbar (millibar).

Efficient for Low Gas Loads: They perform well when handling low gas loads, making them suitable for applications where gas flow rates are not excessive.

In a 2 stage rotary vane pump, the pumping process is divided into two sequential stages, each with its own set of vanes. The first stage, known as the high-vacuum stage, operates similarly to a 1 stage pump, creating an initial level of vacuum. The gas discharged from the first stage then flows into the second stage, where further compression occurs, resulting in even lower vacuum levels.

Higher Vacuum Levels: 2 stage pumps are capable of achieving significantly higher vacuum levels compared to 1 stage pumps. They can reach vacuum levels as low as 0.1 mbar or even lower.

Improved Gas Handling: These pumps are effective in handling higher gas loads and can efficiently evacuate larger volumes of gas.

Enhanced Backstreaming Resistance: The two-stage configuration provides better resistance to backstreaming, preventing oil or contaminants from reaching the vacuum chamber or system.

Suitable for High Vacuum Applications: 2 stage pumps are well-suited for applications requiring high vacuum levels, such as analytical instruments, vacuum coating, and semiconductor manufacturing.

An Introduction to Mechanical Booster Vacuum Pumps

What is a Mechanical Booster Vacuum Pump?

Imagine you are tasked with designing a high-quality vacuum system for a chemical processing plant or a pharmaceutical manufacturing facility. You need a vacuum pump that is efficient, reliable, and capable of achieving the desired vacuum levels for your specific process requirements. Enter the mechanical booster vacuum pump, a versatile and powerful tool that can help you achieve your goals!

A mechanical booster vacuum pump, also known as a Roots pump, is a type of positive displacement pump that can be used to increase the vacuum level in a system. It is designed to operate in conjunction with a primary pump, typically a rotary vane or rotary piston pump, to improve the overall performance and efficiency of the vacuum system. The mechanical booster pump is an essential component in many industrial processes, offering numerous advantages and benefits over other types of vacuum pumps.

In this blog post, we will take an in-depth look at mechanical booster vacuum pumps, exploring their working principle, advantages, and typical applications in various industries. By the end of this article, you will have a better understanding of why mechanical booster vacuum pumps are a valuable tool for process engineers and how they can help optimize your vacuum system.

How Does a Mechanical Booster Vacuum Pump Work?

The mechanical booster vacuum pump operates on the principle of positive displacement, which involves trapping a fixed volume of gas and then expelling it from the pump. The pump consists of two counter-rotating lobes, or rotors, that are synchronized by a pair of gears. As the rotors turn, they create a series of expanding and contracting volumes between the rotors and the pump casing. This action draws gas into the pump, compresses it, and expels it through the exhaust.

Since the mechanical booster pump does not compress the gas internally, it relies on a primary pump to reduce the gas pressure before it enters the booster. This allows the mechanical booster pump to operate more efficiently, as the gas is already at a lower pressure when it reaches the booster stage. The combination of the primary pump and mechanical booster pump results in a more effective and powerful vacuum system, capable of achieving deeper vacuum levels and higher pumping speeds than a primary pump alone.

It is important to note that mechanical booster vacuum pumps are not designed to operate at atmospheric pressure. In fact, they can suffer severe damage if they are operated in this manner. To prevent this, a bypass valve was often installed to protect the pump from overpressure, allowing it to operate within its optimal pressure range but with variable frequency drives getting economical, Vacuum Booster motors are nowadays provided with variable frequency drives.

What are the Advantages of Using a Mechanical Booster Vacuum Pump?

There are several key advantages to using a mechanical booster vacuum pump in your vacuum system, including:

Increased pumping speed: By augmenting the performance of the primary pump, a mechanical booster pump can significantly increase the pumping speed of a vacuum system. This means that the system can achieve the desired vacuum level more quickly and efficiently, saving time and energy.

Improved vacuum level: Mechanical booster vacuum pumps can help achieve deeper vacuum levels than a primary pump alone. This is particularly beneficial in applications where a high vacuum level is required for optimum process performance.

Energy efficiency: Due to their design and mode of operation, mechanical booster vacuum pumps are more energy-efficient than other types of vacuum pumps. This translates to lower operating costs and a reduced environmental impact.

What are Some Typical Applications for Mechanical Booster Vacuum Pumps?

Mechanical booster vacuum pumps are used in a wide range of industries and applications, including:

Chemical processing: In chemical processing plants, mechanical booster vacuum pumps are used to optimize the vacuum levels for various processes, such as distillation, evaporation, and drying. This ensures that the products are of high quality and that the processes are as efficient as possible.

This helps to ensure that the final products are safe, effective, and of the highest quality.

Vacuum furnaces: Mechanical booster vacuum pumps are used in vacuum furnaces to achieve the desired vacuum levels for various heat treatment processes, such as brazing, sintering, and annealing. This helps to improve the quality and performance of the treated materials.

In conclusion, mechanical booster vacuum pumps are an indispensable tool for process engineers in various industries. Their ability to increase pumping speed, achieve deeper vacuum levels, and operate efficiently makes them an ideal solution for optimizing vacuum systems in chemical processing, pharmaceutical manufacturing, vacuum furnaces, and more.

Kinds of Peripheral Flow Sends and Their Doing work Mechanism

Kinds of Peripheral Flow Sends and Their Doing work Mechanism

A Peripheral Flow Pump can be a device that works well for the flow regarding fluids. The mechanism of your pump works simply by recirculating fluids numerous times. The pump can also be used to create large pressure plus head. This mechanism is quite useful in many applications. Here are some plus the the pump's characteristics. Let's discuss the sorts of peripheral flow pumps and their being employed mechanism.

The efficiency on the pump can always be determined from their characteristic curve. In general, the efficiency contour is plotted while H = f (Q). Flow rate is add up to 0 when the head is at its highest. Flow rate as well as head increase throughout direct proportion to each other. This relationship is also applicable to the electricity input and output with the pump. These Peripheral Flow Pump Manufacturer curves differ for various kinds of pumps. These differences within the curves are from the different design and efficiency options that come with the pumps.

Essentially the most common form connected with rotary pump is a gear pump. It comprises of two meshed equipment that rotate from a casing. The areas between the items teeth trap along with push the fluid, creating centrifugal induce. Unlike the scooping actions, fluid doesn't return to the meshed part. Gear pumps are utilized in different hydraulic power packs and motor vehicle engine oil pumps. A gear pump's doing work principle is a bit like a car tyre.

A circumferential flow pump includes a rotor with some sort of plurality of circumferential flow impellers mounted on the rotor. YOUR stator surrounds the particular rotor. It also offers a centrifugal magnetic generator coupled to it. Once these two pumps interact to move liquid, they will discharge it over the suction port. The next seal means THIRTY-ONE and third close off means 32 are disposed in the housing between the rotor as well as the pump stages.

The other type of peripheral flow pump is often a rotary impeller. It involves multiple radial vanes that are aligned along its periphery. The impeller rotates together with increasing pressure within the casing channel. The fluid included in the pump is more affordable than the substance outside the pump motor. A spiral path is formed over the perimeter of the pump the location where the vortices meet. The greater vortices there are, the greater this pressure.

The great things about peripheral pumps are make can generate a top pressure even should the flow is very low. Since the impeller turns close to the pump's volute, the actual difference in demand between the source and output is substantial. Peripheral pumps are less costly than centrifugal pumps and possess a higher self-priming potential. These features make them a good choice for you are able to. There are advantages to choosing this type of pump.

Unlike displacement penis pumps, a peripheral knock out is characterized with a smaller size. Their small size makes for smaller measurements for any same output. They're also suited to pure, non-abrasive essential fluids. They can be used in several different pumping applications, as well as pressure-boosting, car-wash, along with chemical industries. The only downside to using this pump type is always that it's less powerful than its displacement knock out cousin.

A turbo hoover pump is another example on the peripheral flow pump motor. Its turbo-vacuum pump motor reduces the pushed force generated because of the discharged gas. It is equally capable of working together with corrosive fluids. It also has the benefit of being easy to keep up. In addition, it's simple to control. And, as a result, it's an outstanding choice for applications that require a high level associated with efficiency.

A turbo void pump comprises a housing, rotor, in addition to discharge port. The rotor compresses and discharges gas. The motor devices the pump over the discharge port and a second purge gasoline supply port. The pump is supported by bearing means at the axial ends. The current invention can defeat these problems, and was designed to be simple and inexpensive. It also provides high-speed functioning. This type involving pump can operate at high pressure and can be manufactured at less costly.

Correct use of rotary vane vacuum pump

How to apply the rotary vane vacuum pump correctly is described in detail below.

Before application, the product specification should be read carefully, and the quality of shipment should be checked after opening the case. Receive spare parts and technical documents, remove exhaust protective parts. According to the request device, wiring, trial steering. Water-cooled pumps receive water.

In order to avoid fuel injection due to oil return and reversal, the pump mouth should be opened first, and the oil in pump should be transferred to the tank by hand tray according to the rules. At the same time, check the oil level, should be above the oil mark center, but do not fill the oil mark, more to release.

Auxiliary method to distinguish steering. Put the sheath on the pump mouth, if it is absorbed after opening the pump, it is positive, blown off and reverse. The normal sound is positive, and the abnormal sound is reverse.

If a pneumatic solenoid valve is installed at the pump mouth, it should be installed horizontally and operated simultaneously with the pump.

Gas ballast valves should be used when the relative humidity is high or the condensable vapors such as water vapor in the extracted gas are used.

Vacuum pump oil is recommended according to the specification. Note that ester vacuum pump oil can not be mixed with mineral oil type vacuum pump oil and other oils. It must be cleaned strictly before it is replaced with ester vacuum pump oil.

The limit pressure of the pump shall be checked by a compact mercury vacuum gauge. Full pressure gauge should pay attention to pairing calibration and standby comparison of gauge and regulation. It is advocated to install a ball valve between the regulator and the pump under test. Closing the valve at unexpected time can prolong the operation time of regulation.

History of Air Compressor

You guys are here to know the history of air compressor. So, let’s begin. The air compressor was first invented in 1650 by a German physicist and engineer called Otto Von Guericke. Since then, the air compressor was started its journey and developed in time for various purposes.

There are lots of tasks that can be done with the help of an air compressor. Besides, it is used with works like construction, building, and commercial purposes. So, get one and read the below blog to know more. If you need to know review, you should follow https://topaircompressorreviews.com/

History

A German physicist and engineer called Otto Von Guericke invented a vacuum pump in 1650 and experimented with air pressure and how it was utilized to achieve different means. His air pump demonstrated how air worked with combustion, and his experiments led the way for further studies on the use of compressed air.

The blowing cylinder compressor was the first to be invented and was the early air compressors. It was invented in 1762 that could produce 14.5 pounds per square inch. Then on 1829, a compound air compressor was patented. After 40 years in 1872, the compressor was improved with the use of water jets that cooled the cylinders.

Applications

An air compressor is an excellent tool that is quite handy and has lots of applications. It helps people in supplying high-pressure clean air to fill the gas cylinder. It also helps people supplying moderate-pressure clean air to submerged surface supplied diver as well. In addition to that, you guys can use this tool to supply moderate-pressure clean air for driving some office and school building pneumatic HVAC control system valves. Moreover, you guys can use this compressor to supply a large amount of moderate-pressure air so that you all can power pneumatic tools like jackhammers, filling high-pressure air tanks, tires, and do various industrial works too.

Types of Air Compressors

There are many types of air compressors available, which are suitable for different tasks and works.

Rotary Screw Compressors

It is one of the most popular and useful compressors that has common compression systems and used for automobiles. They consist of two helical rotor screws that push air into a small environment. The best thing about these types of air compressors is light in weight, compact, and the maintenance cost is quite low. It is suitable for those types of works that involve air-powered tools that require a more uniform flow of power.

Reciprocating Compressors

It is also an impressive compressor that achieves compression with pistons that reciprocate inside tandem cylinders. These types of air compressors are used when high compression ratios are needed for a task but without a high flow rate. On the other hand, these types of compressors are used on those devices, which require low speeds.

Rotary Vane Compressors

The Rotary vane compressors have some blades located inside the rotor, which is slide in and out of pockets. At the same time, the rotor blades are what achieve compression. However, this compressor can have multi-stages that are preferred pressure is produced after several stages. It can also come in portable or stationary compressors as well.

Scroll Compressors

Scroll compressors have spiral vanes to compress air. In that case, one of the vanes is stationary while the other moves that create energy of compressed air that can help in many tasks. You guys can use these compressors with other tools so that you all can do lots of hard tasks within less time and efficiently.

Maintenance

I mentioned in the above article that an air compressor is a useful tool. But, to ensure its efficiency with no leaks, you have to take through routine maintenance. Its maintenance includes monitoring and replacing air compressor fittings. You have to do the below tasks to keep your air compressor well-maintained.

·         Check for air leaks and oil.

·         Check differential pressure in the compressed air filter.

·         Determine whether or not the oil in the compressor should be changed.

·         You must have to verify the safe operating temperature of your air compressor more often.

·         You should also drain condensation from air receiver tanks as well.

Conclusion

Lastly, I would like to say that the air compressors are handy and useful tools that are used for different purposes and tasks. So, you should get one for your works. Now, if you have any further questions, then ask me in the comment.

27 basic knowledge points of centrifugal pump!

1. What is the main working principle of centrifugal pump? The motor drives the impeller to rotate at a high speed, causing the liquid to generate centrifugal force. Due to the action of centrifugal force, the liquid is thrown into the side channel and discharged out of the pump, or into the next stage impeller, so as to reduce the pressure at the inlet of the impeller and form a pressure difference with the pressure acting on the suction liquid. The pressure difference acts in the liquid suction pump. Due to the continuous rotation of the centrifugal pump, The liquid is continuously inhaled or discharged. 2. What are the functions of lubricating oil (grease)? Lubrication, cooling, flushing, sealing, vibration reduction, protection and unloading. 3. What is the three-stage filtration of lubricating oil before use? Level I: between the original lubricating oil barrel and the fixed barrel; The second stage: fixed between the oil barrel and the oil pot; Level 3: between the oil pot and the refueling point. 4. What is the "five determinations" of equipment lubrication? Fixed point: add oil at the specified point; Timing: oil the lubricating parts according to the specified time and change the oil regularly; Quantitative: quantitative refueling according to consumption; Quality determination: select different lubricating oils according to different models and keep the oil quality qualified; Fixed person: each refueling part must be in the charge of a special person. 5. What is the harm of water in pump lubricating oil? Water can reduce the viscosity of lubricating oil, weaken the strength of oil film and reduce the lubrication effect. Water below 0 ℃ will freeze, which will seriously affect the low-temperature fluidity of lubricating oil. Water can accelerate the oxidation of lubricating oil and promote the corrosion of low molecular organic acids to metals. Water will increase the foaming property of lubricating oil and make the lubricant easy to generate foam. Moisture can rust metal parts. 6. What are the maintenance contents of the pump? Carefully implement the post responsibility system, equipment maintenance and other rules and regulations. The equipment lubrication shall be "five fixed" and "three-level filtration", and the lubrication equipment shall be complete and clean. Maintenance tools, safety facilities, fire-fighting equipment, etc. shall be complete and placed neatly.
