Vacuum pump manufacturers

Vacuum pump performance reflects the use of equipment, then the impact of the performance of the factors which? The following vacuum pump manufacturers to introduce:

1, the pump body layout:

On a single pump, simple wear parts of the steam nozzle, nozzle is worn, not only will affect the function of the pump, but also to add the operating costs of the system.

2, the impact of condensed water:

Condensed water has of little importance position in the vacuum pump, in order to ensure that the condensed water can be full of steam condensation, the pump discharge pressure of water vapor partial pressure in the need for higher than the corresponding full steam pressure, so the condensed water temperature should be lower than the pressure under the full temperature, can guarantee the normal operation of the pump body. The other is the key power condenser condensation, condensation condenser, the steam condensation due to no time to go directly to the next level pump, pump load increased, the gas pump can pump effect. Therefore, the inlet temperature, flow rate and the use of condenser have great influence on the function of the pump.

3, the impact of steam:

We use the vacuum pump for the steam eruption pump, is full of water vapor as the working medium, the status of steam on the function of the pump has a decisive impact. Wet steam not only affects the function of the pump, but also the corrosion of the steam nozzle, add the amount of steam pump, so that the pump operating conditions become unstable.

4, internal leak:

In the whole process of liquid steel treatment, the vacuum degree of the system increases with the decrease of the amount of liquid gas. In the early stage of the treatment of liquid steel, the system vacuum is low, the amount of gas is large, the demand of the first stage pump pumping capacity can be large, usually choose a number of pumps in parallel to increase the amount of pumping system. However, when the vacuum degree of the system increases, the amount of gas is reduced. In order to reduce the steam consumption and save energy, a few of the pumps in the front stage are needed to be closed. Secondly, the pump nozzle is composed of two parts, the two part is on the flange connection, a connecting flange in the pump body, if the joint seal because reasons of steam leak, will also give the pump function influence.

5, the impact of the environment:

The influence of environment mainly refers to the pumped gas system of pollution in the disposal process of molten steel, molten steel will emit a lot of gas, together will be part of the subtle oxidation of small particles are inhaled Fenpi vacuum pump, these small particles will accumulate adhesion on the pump body, reduces the exhaust pipe flow path by prolonged pumping time, decrease of gas pumping function.

Thus, the pump body layout, condensed water, steam, internal leakage and environment will affect the performance of the vacuum pump, in the use of equipment should pay attention to these points.
