Ring vacuum pump is widely used in metallurgy, chemical industry, food, electronic coating and other industries. But sometimes there is a problem that the water can not be pumped. What is the matter? Let's discuss the reasons for this:

In the process of using water ring vacuum pump as water diversion pump, the water can not be pumped due to improper operation

(1) Lift pump seal box (commonly known as packing), water pipeline or flange leakage.

(2) The circulating water volume of water ring vacuum pump is too large, and the circulating water will return.

(3) The circulating water is not connected or the water pipe is blocked, and the valve is not opened.

(4) The rotation number of water ring vacuum pump is not enough or reverses, which leads to burning motor.

(5) The outlet valve of lifting pump is not closed tightly.

(6) The disc of water ring vacuum pump leaks and the pump is seriously worn or damaged.
