What are the reasons affecting vacuum pump efficiency _

with the rapid development of Chinese economy, Chinese vacuum pump industry has maintained the momentum of rapid growth, to realize the stable and continuous development. At the same time of rapid development, vacuum pump companies and users are to explore how to contribute to the efficient operation of vacuum pump, this is a factor that influence efficiency of vacuum pump. Let's take a look at, and then have a look.

affect vacuum water pump efficiency:

1. Steam pressure

low steam pressure and pressure fluctuation has a great influence on the capacity of the vacuum pump, so the steam pressure should not be less than the required working pressure, but at the end of the day has been used in the design of vacuum pump structure design to increase the excess of flue gas and vacuum steam pressure. In addition, the boiler supply

steam pressure stability. It is best to use steam boiler steam jet pump. There is no such steam pressure fluctuations to ensure the stability of the vacuum pump.

2。 Circulating cooling water

if insufficient cooling water discharge, condenser will generate heat, air can produce noise, vacuum will fell rapidly, even will return the exhaust steam. Condensate in multistage pump plays a decisive role. Condensate can completely condensing water vapor, and under the vacuum pump discharge pressure will be the shunt.

must be higher than the corresponding full steam pressure, thus condensed water temperature is lower than the steam pressure, to ensure the normal operation of pump.

3。 Nozzle

the nozzle is an important part of vacuum pump performance and existing problems are: nozzle errors, loaded askew, jams, damage, corrosion and leakage, no matter what preventive measures, nozzle clogging are inevitable. On the one hand, due to the residual iron and slag in installation steam pipeline clogging nozzle; On the other hand, when the vacuum pump system downtime, steam pipe is easy to rust, when using plug nozzle drop rust spots.

4。 Use environment

environment is mainly refers to the influence of the gas is pumped into the system of pollution, in the process of molten steel processing, steel is then ready to discharge a large amount of gas, but also there will be a part of the subtle oxide sheet jelly and other small particles inhaled in the vacuum pump, these small particles can accumulate on the pump body of adhesion, reduced the spare pipe flow guidance, longer time, pump can qigong downward.

5。 Use vacuum pump type

generally includes vacuum pump water ring vacuum pumps, rotary vane vacuum pumps, rotary piston vacuum pumps, diffusion pumps, roots pump, molecular pump etc, customers can choose according to their process needs suitable vacuum pump and the economic cost is saved, and can make the biggest work efficiency.

through the introduction, we can preliminary understanding what are factors that influence efficiency of vacuum pump work. In the process of we use in the future, avoid error, better use of vacuum pump.
