The Characteristics of Diaphragm Vacuum Pump

What is a vacuum pump? The vacuum pumps are a rotary variable displacement vacuum pump that must be used with a foreline pump. It has a large pumping speed over a wide pressure range and is insensitive to dust and water vapor in the extracted gas. It is widely used. Metallurgy, chemical, food, electronic coating, and other industries.

Hawach diaphragm vacuum pump is pressure cast by aluminum alloy and sprays plated by anti-corrosion coating. It is light and beautiful, with a wide range of application. The air vessel is processed by Teflon, it has a high level of corrosion resistance and can meet the requirement of all kinds of the working environment.

Vacuum pump features

1. Large pumping speed over a wide range of pressures;
2. The compression is relatively low, and the effect on hydrogen gas pumping is poor;
3. There is no compression in the pump chamber, no exhaust valve.
4. There is a gap between the rotor and between the rotor and the casing, no lubrication, and the friction loss is small, which can greatly reduce the driving power, thereby achieving a higher rotation speed.

Characteristics diaphragm vacuum pump

1. It does not need any working medium and causes no pollution. At the same time, the air exchange vessel contains filter material which ensures the purity of air.
2. It uses new technology and new material in the manufacturing process and is convenient for the move. It works smoothly in order to ensure perfect vacuum degree and high air velocity.
3. It adopts the frictionless movement of the membrane without producing heat and frictional loss. The membrane is mainly made of imported rubber with corrosion resistance and long service life.
4. There is a self-cooling exhaust system in the pump which ensures 24 hours of continuous running.
5. It adopts the design of adjustable pressure which can meet a certain range of vacuum degree and air flow rate.
6. It mainly uses the classic imported bearing to ensure smooth running, low noise and high working efficiency.

Vacuum pump use precautions

The function of the vacuum pump is to remove gas molecules from the vacuum chamber and reduce the gas pressure in the vacuum chamber to achieve the required vacuum. In general, there is a large range from atmospheric to very high vacuum, and so far no vacuum system has covered this range.

For optimal configuration, the following points should be considered when selecting a vacuum system:

1. Determine the working vacuum range

It is first necessary to check the vacuum required to determine each process. Because each process has its own range of vacuum levels, it must be carefully studied.

2. Determine the ultimate vacuum

The ultimate vacuum of the vacuum pump system is checked on the basis of determining the degree of vacuum required by the process since the ultimate vacuum of the system determines the optimum working vacuum of the system. In general, the system’s ultimate vacuum is 20% lower than the system’s operating vacuum and 50% lower than the feline’s ultimate vacuum.

3. Type of pumped gas and pumping capacity

Check the type of pumping and the amount of pumping required to determine the process. At the same time, consideration must be given to determining the appropriate exhaust time and the amount of gas produced during the pumping process.

At present, vacuum pumps have been widely used in metallurgy, chemical, food, electronic coating, and other industries. Therefore, the quality of the vacuum pump determines the development of our metallurgical, chemical and other industries, then we need to pay attention to some related matters when using the vacuum pump, and protect it to the maximum extent.

If the volatile organic solvent is distilled, the organic solvent is absorbed by the oil, which increases the vapor pressure, thereby reducing the evacuation efficiency. If it is water vapor, the oil becomes an emulsion and the vacuum pump is pumped.
