One lifetime and worthwhile investment you can make today is purchasing a vacuum pump. This is a great device used for a wide range of applications and in many different industries. Industrial liquid vacuum pumps work effectively in removing water or liquids from a sealed or an airtight container, paper, etc. and then make a vacuum. The fluids used in a certain application then move into the vacuum left behind due to the difference in pressure changes. Otto von Guericke built the first vacuum pump in 1650, and many other exceptional models have graced the industry ever since. Vacuum pumps
Failure Possible Causes Methods 1.Pump not suck water, both pointers of manometer and vacuometter severly jump. a:Water input the water pump is not enoughb:Air leakage on water input pipes and instruments a:Input more water into water pumpb:Tighten and block the air leakage parts 2.Pump not suck water, high vacuum shown on vacuometer a:Bottom valve not opened or blocked upb:Too large resistance of the suction pipelinec:too high suction height a:adjust or replace bottom valveb:clean or replace water input pipesc:reduce water input height 3.No water out through pressure is shown on manometer a:too large resistance on outlet pipelineb:Uncorrect rotating directionc:Impeller blocked up d:Insufficient
