FAQ:
1. What is the working principle of a diaphragm vacuum pump?
The motor drives the diaphragms on the left and right plungers to reciprocate one after the other through the reduction box. In the left and right pump chambers, there are four upper and lower one-way ball valve diaphragms, which cause the volume change in the working chamber, forcing the four one-way ball valves to open and close alternately, so as to continuously suck and discharge the liquid.
2. Why is the flow rate of the diaphragm vacuum pump reduced?
There is air leakage in the suction pipe, the suction pipe is not immersed in liquid, the suction port diameter is small, the end face gap is too large, the pump shaft speed is slow, the filter is blocked, and the pump is worn.
