Water ring vacuum pump vacuum low reason -

water ring vacuum pump vacuum lower results in descending of condenser vacuum, a direct impact on the running efficiency, ensure that the output of the water ring vacuum pumps for safety and economical operation is of great significance. This paper introduces the phenomenon of the two phenomena and put forward the solution.

water ring vacuum water pump vacuum for two reasons: low water ring vacuum pump itself has a problem, or due to poor sealing pipe system and cause gas leak.

in order to determine the cause of the problem, for the vacuum pump, to cut off the suction pipe system, then put the water ring vacuum pump water ring connected directly to the experiments in an airtight container. line the trachea directly connected to carries on the experiment in airtight container. Connect the water pump to an airtight container, start the water ring vacuum water pump. If the pressure and vacuum degree did not change after 15 to 20 minutes, please specify the pump itself has a problem. If the pressure and vacuum degree gradually rise to normal, please find sealed pipeline system, resulting in gas leakage. If the increased pressure and vacuum, but do not meet the normal, water ring vacuum pumps and piping system will appear problem.

in the field, a simple experiment method is closed near the intake valve ( For water ring vacuum pump) Or shut off the valve pipe ( For the extrusion machine) , start the water ring pump, the replacement of inspiratory mouth near the vacuum gauge or pipe pressure gauge can also find out the cause of the problem. In this way, it is necessary to ensure the reliability of the valve seal.

if the problem is in the pipeline system, can the pipeline pressure test, to find out the air leakage of the local area. The experiment can be in 1. 5 to 3 under atmospheric pressure. Tighten all bolts, the solution was applied to easy leakage of local area, such as flange, threaded joints, local holes and cracks in the weld and pipeline. If the local leakage, were yu solution there will be a big bubble.

at the same time, the reason of low vacuum is water ring vacuum pump disc impeller wear gap is big, have blocked, circulating water is insufficient, the system leakage, slow speed, the position is different, and so on. This kind of circumstance also need specific analysis. The reason for this is for reference only. There is a problem to contact after-sales personnel.

At the same time, as the recent research of JT shows, the benefits of improved productivity and firm performance can make implementing basic management practices worth it.
