The working environment and conveying medium of Roots blower are the two main causes of corrosion. Therefore, roots blower should not be installed in the environment with high air humidity; secondly, for the corrosive medium, we should communicate with the manufacturer in advance to select a suit...

One of the basic considerations in designing a high vacuum system is the time required to pump the container to a given pressure. The time range is usually from a few minutes to a few hours. However, in some cases, the required pumping time may be seconds or days. It is difficult to estimate the ...

The development of vacuum heat treatment process is inseparable from the development of equipment. Improving the equipment technology level to meet the process requirements is often closely related to the development of supporting parts technology. Vacuum pump unit of expansion Before the invent...

What factors affect the selection of Roots blower? Due to the different uses and working conditions of Roots blowers, the roots blowers in each construction scene are different, so hundreds of types and parameters of Roots blowers are produced. Today, EVP vacuum pump manufacturer will give you a ...

Industrial chiller is widely used in plastic, electronic manufacturing, electroplating, pharmaceutical and chemical industry, ultrasonic cooling, printing and other industrial production. It controls the required temperature of modern industrial mechanization production, thus greatly improving th...

Booster pump oil of features and uses The booster pump oil is made from paraffin base oil, which is first cut into narrow fraction by molecular distillation after solvent assisted dewaxing and deep refining, and then by adsorption refining and vacuum degassing. It is suitable for domestic and for...

The safety valve will be used in the process of using the three blade roots blower. For the users of Roots blower, how to correctly adjust the safety valve is very important. The following EVP vacuum pump manufacturer will introduce the adjustment method of safety valve of three leaf roots blower...

Vacuum inlet filter side channel blower air filter It is widely used in the industrial application of vacuum system. Effectively prevent solid particles or dust from being sucked into vacuum pump or system. It can effectively protect the components of the vacuum system by reducing the wear of the...

There are generally two sealing methods for vacuum pump. Packing seal refers to the sealing method with packing, which can be used for dynamic and static coordination. Generally, a small amount of leakage is allowed in the dynamic fit room. Mechanical seal is used in the occasion of high requirem...

According to the calculation, after the pumping speed of the vacuum pump is confirmed, the pump model must be carefully selected. For example, oil sealed mechanical pump with pumping speed of 150L / s, H-8 slide valve pump needs 17kw of driving power, while yz-150 cycloid pump only uses 13kw. If ...
