We all know that there will be a lot of problems during the use of vacuum pump, so how do we solve the trip of vacuum pump unit?

1. The suction port of the vacuum pump unit should not be connected from the bottom of the tank, only one suction pipe at the top of the tank body should be kept.

(1) Because if the suction is from the bottom of the tank, when the vacuum pump unit stops working after each use of the vacuum pump unit, the suction pipe and the vacuum pump unit are unblocked due to the formation of negative pressure in the tank. Under the action of negative pressure, the water in the pump will be sucked into the tank;

(2) When the vacuum pump unit is started next time, a large amount of water is sucked into the vacuum pump unit at the bottom, which causes the overload of the water ring vacuum pump unit and causes the over current of the water ring vacuum pump unit to trip;

2. Two vacuum pump units are combined into a pipeline, and there is no valve between the two pumps. Only a one-way valve is installed at the inlet. The one-way valve can not achieve the effect of complete sealing.

Since the working mode of the vacuum pump unit is one for use and one for standby, when one of the vacuum pump units is working, the water in the other vacuum pump unit will be pumped, and even the circulating water and atmosphere will be pumped back from the exhaust pipe, which will also be the cause of the trip of the water ring vacuum pump unit.

Hope that the above introduction can help you solve the problem, the daily use of vacuum pump unit should pay attention to, according to the roots blower manufacturer's instructions to operate, so as to avoid failure.
