Influence the efficiency of the water ring vacuum pump _

use device after a period of time, the device will often appear some issues affect their working efficiency. For water ring vacuum pump, is no exception. So let us know the reason why the water ring vacuum pump efficiency briefly.

1, the nozzle

nozzle is the important component of water ring vacuum pump performance. The errors in the assembly, installation, infarction, damage, corrosion and the leaking of nozzle. No matter what preventive measures, nozzle infarction are inevitable. On the one hand, due to the equipment of the steam pipe, the pipe residual iron and slag lead to the nozzle expansion; On the other hand, when the water ring vacuum water pump system outage, steam pipes in use process, easy to rust, rust will drop infarction nozzle.

2, operating environment

environmental impact is mainly refers to the pollution by extraction on the system. In the process of molten steel processing, steel gas release a large amount, at the same time, a few small particles ( Oxide powder, for example) Inhaled water ring vacuum pump. Small particles will accumulate and adhesion on the water pump body, thereby reducing the pumpage of trachea, extend the pumping time and reduce pumping quantity.

3, steam pressure

low steam pressure and pressure fluctuations had a great influence on the performance of the water ring vacuum pump, so the steam pressure should not be less than the required working pressure, but the structure design of water ring vacuum pump set too much steam pressure. Will increase the extraction ability and vacuum degree. In addition, in order to ensure the stability of the pressure of steam in the boiler, it is best to use boiler to steam pump radiation supply work, so that the steam pressure will not swing, and ensure the stability of water ring vacuum.

4, circulating cooling water

in the absence of cooling water supply, the condenser will be hot, the air will become bigger, the vacuum will decline rapidly, and steam will return to pump the trachea. In the multistage water ring vacuum pump, the influence of condensation water is small and insignificant. Condensate can completely condensing steam. Water ring vacuum pump exhaust pressure of water vapor partial pressure must be higher than the corresponding full steam pressure. Therefore, under the condition of ensure the pressure, the temperature of the condensate temperature less than full, in order to ensure the normal operation of the pump body.

after understanding the above water ring vacuum pump efficiency, we will pay more attention to these problems in the future, so that the equipment work better for us.
