What causes will affect the vacuum pump

What causes will affect the vacuum pump

The low steam pressure and pressure fluctuation have great influence on the ability of vacuum pump, so the steam pressure should not be lower than the required operating pressure, but the structural design of vacuum pump has been finalized, too much improvement of steam pressure will not increase the air extraction and vacuum degree. In addition, in order to ensure that the steam pressure supplied by the boiler is stable, it is better to use a boiler to supply the working steam to the steam jet pump, so that the steam pressure will not fluctuate and the function of the vacuum pump is stable.

Due to the lack of cooling water supply, the condenser will heat up, the sound of air flow will increase, the vacuum degree will drop rapidly, and even the steam will return to the extraction pipe. The condensate has no significant effect in the multistage vacuum pump. The condensate can fully condense the steam. The partial pressure of the water vapor in the discharge pressure of the vacuum pump is necessary to be higher than the corresponding full steam pressure. Therefore, the temperature of the condensate should also be lower than the full temperature under the pressure to ensure the normal operation of the pump body.

When the vacuum pump is in the limit condition, there is little or no water discharged from the first stage. Therefore, the first stage pump has a lot of water discharge, which can be considered as leakage of the system. The common causes of air leakage are: the gasket is not installed, installed incorrectly or damaged, the bolt is not tightened, the flange surface is damaged, the weld has sand holes, and the joint (pressure gauge, vacuum gauge, etc.) is not installed properly.

Nozzle is an important part that affects the function of vacuum pump. There are some problems: wrong installation, crooked installation, blocking, damage, corrosion and leakage of nozzle. No matter what preventive measures are adopted, nozzle blocking is inevitable. On the one hand, the residual iron and welding slag in the steam pipe will block the nozzle; on the other hand, when the vacuum pump system is out of service, the steam pipe is easy to rust, and the rust spots will fall to block the nozzle during use.
