Advantages and disadvantages of rotary vane vacuum pumps, uses of rotary vane vacuum pumps

The advantages and disadvantages of rotary vane vacuum pumps are mainly as follows:

1. The advantage of rotary vane vacuum pump is the vacuum degree of the newly put into use pump.

Relatively high.

2. The gas compression in the rotary vane vacuum pump is isothermal. Since there is no exhaust valve and friction surface, dusty gases, condensable gases, and gas-water mixtures can be extracted. With these outstanding features, it is still widely used despite its low efficiency.

3. The structure is simple, the manufacturing accuracy is not high, the processing is simple, and the structure is compact.

4. It is equipped with a pump stop and anti-oil return device, which is convenient to start again.

5. It is equipped with a gas ballast valve, which can remove a small amount of water vapor.

6. The exhaust port is equipped with an oil mist trap to avoid environmental pollution.

7. It can still maintain a high pumping speed under low pressure.

8. Low noise and low vibration. Information**.

Rotary vane vacuum pump is a common mechanical vacuum pump, and its advantages and disadvantages are as follows:

Pros:1The pumping speed is fast and can reach high vacuum.

2.It has strong pumping capacity and is suitable for occasions with large flow rate and high pressure.

3.Small size, light weight, easy to handle and install.

4.Simple maintenance, easy to clean and replace wearing parts such as rotary vanes.

5.Relatively low.

Cons: 1Lubricating oil needs to be added, and there is oil contamination and the influence of oil vapor on the pumped substance.

2.Lubricating oil needs to be replaced and filtered regularly, increasing maintenance costs.

3.It is not suitable for occasions that require high purity of the pumped substance, such as semiconductor, optical, medical and other fields.

In conclusion, rotary vane vacuum pumps have many advantages, but there are also some disadvantages, and the suitable vacuum pump should be selected according to the specific use needs.

Rotary vane vacuum pump is a kind of mechanical vacuum pump, its characteristics and working principle are as follows:

Features: Rotary vane vacuum pump has simple structure, reliable performance and low maintenance cost.

The pumping speed is high, which can reach the range of 500-1000L S.

It has a wide range of applications and can be used in various working conditions such as low vacuum, medium vacuum and high vacuum.

Working principle: The main component of the rotary vane vacuum pump is a centrifugal pump composed of rotating vanes and fixed vanes, and the centrifugal force generated by rotating in the pump body can pump the gas out of the pump body to form a vacuum.

The gas forms a pressure difference inside the pump body and flows from the high-pressure area to the low-pressure area.

On inhalation, the rotating vanes rotate rapidly inside the pump body, creating a rotating cavity in which the gas is squeezed and compressed, creating a vacuum.

During exhaust, the gas flows out of the gap between the rotating vanes and the pump body, creating a vacuum.

To sum up, rotary vane vacuum pumps have the advantages of simple structure, fast pumping speed and low maintenance cost, and are widely used in various fields.

Rotary vane vacuum pump is a common mechanical vacuum pump, its principle and structure are as follows:

Principle: The impeller is used to rotate at high speed in the shell to generate centrifugal force, so as to discharge the gas out of the pump body and achieve the purpose of vacuuming.

Structure: The rotary vane vacuum pump is mainly composed of a pump body, a rotating impeller, a fixed impeller and a rotating shaft. Inside the pump body is an oval chamber, and the rotating and fixed impellers are mounted on the shaft, which rotate at high speed by gear transmission.

While the impeller rotates at high speeds, the gas is drawn in from the air intake and then squeezed, compressed, and pushed out of the pump body between the rotating and fixed impellers. The final gas is discharged to the outlet of the pump body.

Rotary vane vacuum pumps are simple in structure and reliable in use, so they are widely used in laboratories, industrial production and other fields.
