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 another through the reduction box. In the left and right pump chambers, there are four upper and lower one-way ball valve diaphragms, which change the volume 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. What should be paid attention to when using diaphragm vacuum pump?
Diaphragm vacuum pumps should be placed as close as possible to the supporting products, and at the same time, the pump should be as close as possible to the pumped liquid. When the inlet pressure exceeds 10 feet (3 meters) of liquid column, a slow pressure regulator is required to extend the service life of the diaphragm. If the equipment is a hard pipe, use a short hose to connect the pump and the pipe. The hose can slow down the vibration and distortion of the pipeline. It is recommended to use a pressure stabilization tank to further reduce pulses in the fluid.
3. How to install the diaphragm vacuum pump?
The best installation should be at the connection of the shortest and straightest inlet and outlet pipelines. Try to avoid additional pipe bends and fittings. The pump body should be able to independently support all pipelines. Moreover, the piping should be arranged in order to avoid stress on the pump body piping.
