Construction Description:

    Figure 1 is a schematic diagram of a rotary vane vacuum pump. The rotors 3 and 7 are tangent to the high vacuum chamber 1 and the lower vacuum chamber 6. The rotors 3 and 7 rotate in the path of the arrow, which drives the rotor sliding in the rotor slot to rotate. Due to the fact the spring 9 And the motion of centrifugal force, the outer conclude of the rotor slides in opposition to the inner floor of the high and minimal vacuum chambers, and the moon-formed room formed by the rotor and the high and low vacuum chambers is moved from the intake nozzle 2 to the exhaust valve 5 and from the air pipe 4 to the exhaust. The valve ten is separated to sort 2 or 3 volumes, and the measurement modifications periodically. When the rotary vane vacuum pump proceeds to rotate at the place shown in the determine, the volumes of A and C progressively boost, and the pumped quantity gas does not enter the air. The nozzle enters the pump, and at the exact same time, the quantity of B and D slowly decreases, and the pressure rises. Then, the exhaust valves 5 and 10 are opened to discharge the fuel out of the vacuum chamber. valve, so it can avoid the fuel from returning to the vacuum chamber. When the pumping force is high, the valves of the higher and lower vacuum chambers are fatigued, which is equivalent to a one-phase pump. When the vacuum degree is substantial, all the fuel enters the vacuum chamber and is then fatigued by the exhaust valve ten. Enter the two-phase pump to work.
    For instance, when the extracted gasoline consists of large vapor fuel, when the gasoline is compressed and the partial stress of its vapor exceeds the saturation stress of the vapor at the temperature of the pump, the vapor is compressed into liquid at this time, and the rotary vane vacuum pump It cannot be discharged, but is mixed in the vacuum oil, which greatly lowers the performance of the pump. If a correct volume of air is combined in, so that when the steam is compressed, its partial pressure is also decrease than the saturated strain of the pump temperature, the steam can be discharged out of the pump prior to it gets liquid, so this collection of pumps above 2X-4 All are outfitted with aeration valve eleven that can place in a specific amount of gas, see Figure 1

     The condition and construction of different vacuum pumps of the 2X series are essentially the identical. The pump is pushed by the motor to the rotor by way of the V-belt. The motor and pump are fastened to the chassis with screw clips.
2X rotary vane vacuum pump is composed of pump physique, large rotor, low rotor, entrance stop plate, rear end plate, large rotor plate, reduced rotor plate, exhaust valve, exhaust hood, sight glass and other elements. See Determine 2 and Determine 3.

      A middle partition is pressed into the 2X rotary vane vacuum pump, and the vacuum pump casing is divided into substantial and low vacuum chambers. The entrance conclude of the substantial rotor protrudes from the front axle the rear stop protrudes from the rear axle. The entrance axle is supported by bearings in the entrance plate, through the oil-limited chamber and out of the entrance plate: the rear axle is supported by bearings in the middle bulkhead. Whilst extending into the low vacuum chamber, the low vacuum chamber rotor is mounted on the rear axle, so the higher and reduced rotors are pushed by the front axle. Both the large and lower rotors have bisected slots, and the “T”-shaped rotary vanes are supported by springs and installed in the slots. The air inlet of the 2X rotary vane vacuum pump has a filter monitor, and the exhaust port has an oil blocking display. There is an air aeration valve on the remaining facet of the sight glass and an oil drain plug on the bottom.  

   2X rotary vane vacuum pump pumping method: as demonstrated in Figure 2, the gasoline enters the high vacuum chamber from the ingestion nozzle. At first, the higher stress is powerful, the higher and minimal vacuum chambers are crammed with environment, and each exhaust valves are opened to exhaust. As the pumping progresses, the air stress decreases (that is, the vacuum degree boosts), the stress of the high vacuum chamber is not enough to push the exhaust valve, and the gas enters the lower vacuum chamber by way of the middle partition, and the stress is not sufficient to thrust the exhaust valve at this time, but The low vacuum chamber enters a certain volume of oil, which will help to open the exhaust valve, and the fuel is also discharged. The discharged fuel is mixed with oil particles, and the oil is divided by filtering the oil display. Only the fuel is discharged from the pump. The fuel path is demonstrated in Determine 2.
    The oil in the oil sealing chamber of the 2X rotary vane vacuum pump is provided from the oil pool A through the gap on the entrance stop plate. The oil in the low vacuum chamber is equipped from the oil pool A by way of the hole in the rear stop plate. The oil in the substantial vacuum chamber is circulated and supplied from the holes in the center partition. The sealing of the front and rear addresses of the 2X rotary vane vacuum pump is created by the oil pool B on the higher part of the pump body flowing into the oil groove by means of the hole of the conclude face chamber of the pump entire body for sealing.

How to install a vacuum pump

A vacuum pump creates a relative vacuum within a sealed volume by drawing gas molecules from the sealed volume. Vacuum pumps can be used in a variety of industrial applications. They also offer various lubrication options. If you are considering purchasing, please understand its functions and features before purchasing.
Vacuum Pump

How it works

The working principle of a vacuum pump is called gas transfer. The principle can be further divided into two basic categories: positive displacement and momentum transfer. At high pressure and moderate vacuum, gas molecules collide and move and create a viscous flow. At higher vacuum levels, gas molecules separate to create molecular or transitional flows.
Another principle of vacuum pumps is fluid-tightness. There are two main types of seals: rotary seals and screw seals. Rotary seals prevent liquid leakage, while screw seals only allow liquids to flow out at higher pressures. Some pumps may not use the third seal.
The flow rate of the vacuum pump determines the machine’s ability to pump a certain amount of material. A higher pumping speed will shorten the drain time. Therefore, the mass flow of the vacuum pump must be carefully considered. The speed and type of vacuum must also be considered.
The working principle of a vacuum pump is to push gas molecules from a high-pressure state to a low-pressure state. This creates a partial vacuum. There are many different types of vacuum pumps, each with different functions. Some are mechanical, some are chemical. In either case, their function is the same: to create a partial or complete vacuum. Vacuum pumps use a variety of technologies and are sized according to the application. Proper sizing is critical for optimum efficiency.
Gas transfer pumps use the same principles as vacuum pumps but use different technology. One of the earliest examples is the Archimedes spiral. Its structure consists of a single screw inside a hollow cylinder. More modern designs use double or triple screws. The rotation of the screw causes gas molecules to be trapped in the cavity between the screw and the housing. The fluid is then discharged at slightly above atmospheric pressure. This difference is called the compression ratio.
Another type of vacuum pump is a diffusion pump. Its main use is industrial vacuum processing. It is used in applications such as mass spectrometry, nanotechnology and analytical instrumentation. These pumps are generally inexpensive to purchase and operate.


Vacuum pumps are essential for many scientific and industrial processes. They are used in the production of vacuum tubes, CRTs, lamps and semiconductor processing. They can also be used to support mechanical equipment. For example, they can be mounted on the engine of a motor vehicle. Likewise, they can be used to power hydraulic components of aircraft. Among other uses, the vacuum pump helps calibrate the gyroscope.
Vacuum pumps are widely used in the pharmaceutical industry and are one of the largest users of this technology. They help deal with hazardous materials and eliminate waste quickly. They are also used in power jets, dump fuel tanks and rear doors, among others. However, they are sensitive to contamination and should only be used in environments where leaks can be prevented. Therefore, choosing the right fluid for the application is very important.
The most popular type of vacuum pump is the rotary vane pump. These pumps are known for their high pumping speed and low pressure. Their efficient pumping capacity allows them to reach pressures below 10-6 bar. Additionally, they are usually oil-sealed and have excellent vacuuming capabilities.
Vacuum pumps are often used to remove air from closed systems. They create a vacuum by reducing the density of the air in the compressed space. This is done by using the mechanical force energy generated by the rotating shaft. When the pump is under pressure, it converts this energy into pneumatic power. When the pressure is different, the energy produced depends on the volume of the gas and the pressure difference between the inner and outer atmospheres.
Vacuum pumps are also used in the manufacture of solar cells. They are used in the manufacture of solar cells, including ingot casting processes as well as cell and module processes. The design of the vacuum system plays an important role in reducing the cost of the process, thus making it profitable. Due to their low maintenance costs, they are an invaluable tool for making solar cells.
Vacuum pumps are widely used in many applications. In addition to industrial and research uses, they are also used in water remediation.

Oil Lubrication Option

Vacuum pumps are available in a variety of oil lubrication options. Choosing the right lubricant can help protect your vacuum pump and maximize its performance. Different base oils may contain different additives, such as antioxidants, and some contain additional additives for specific purposes. You should choose an oil with the right concentration of these additives for optimal lubrication of your vacuum pump.
Vacuum pumps are usually lubricated with paraffinic mineral oil. However, this type of lubricant evaporates as the temperature increases. To minimize evaporative losses, choose a lubricant with low vapor pressure. Also, you should choose lubricants that are resistant to extreme temperatures. Extreme temperatures can put extra stress on the oil and can even significantly shorten the life of the oil.
In terms of viscosity, synthetic oils are the best choice for vacuum pumps. These types of oils are designed to resist gas dissolution and are more resistant to corrosion. Therefore, synthetic oils are ideal for handling aggressive substances. Whether or not your pump needs lubrication, choosing a quality product is important.
The vacuum pump oil should be changed periodically according to the manufacturer’s recommendations. If you use a filter, you should also change the oil as soon as the filter reaches the end of its life. Unplanned oil changes will eventually cause the vacuum pump to not reach its maximum vacuum capacity.
You can buy vacuum pump oil from vacuum pump manufacturers or other suppliers. These options are available in a variety of sizes, and labels can be customized. The oil should be designed for the pump. However, you should check the manufacturer’s recommendations to avoid buying the wrong type.
If you choose to use a synthetic oil, it is important to use a good quality oil. It helps the pump work more efficiently and prolong its life.

After choosing a suitable location, the next step is to install the pump. First, place the pump on a flat surface. Then, screw the pump onto the motor body above the check valve. Make sure the accessories are wrapped with sealing tape and secured with screws. The direction of gas inflow and outflow is indicated by arrows on the pump. The direction of rotation around the pump is also shown.
During commissioning, check the operation of each part of the pump. If the pump is equipped with a pipe connection, the pipe should be the same size and shape as the pump flange. Also, make sure that the piping does not cause any pressure drop. In addition, the first three weeks of operation require the installation of protective nets at the suction ports.
When selecting a pump, consider the back pressure of the system. Too much back pressure will affect the capacity of the vacuum pump. Also, check the temperature of the seal. If the temperature is too high, the seal may be damaged. It could also be due to a partially closed valve in the recirculation line or a clogged filter. Circulation pumps and heat exchangers should also be checked for fouling.
The vacuum pump is usually installed in the chassis area of ​​the car. They can be mounted next to the engine or on a lower support frame. They are usually fastened to the bracket using suitable shock absorbers and isolating elements. However, before installing the vacuum pump, be sure to check the vacuum pump’s wiring harness before connecting it to the vehicle.
In many experimental setups, a vacuum pump is essential. However, improperly installed vacuum pumps can expose users to harmful vapors and chemicals. Appropriate plugs and belt guards should be installed to prevent any accidental chemical exposure. It is also important to install a fume hood for the pump.
In most cases, vacuum pumps come with installation manuals and instructions. Some manufacturers even offer start-up assistance if needed.
