Advantages of diaphragm vacuum pumps:

Diaphragm vacuum pump is a new type of pump, often used in petrochemical, ceramics, metallurgy and other industries. It is characterized by no need to irrigate water and strong self-priming ability.

Features of diaphragm vacuum pump:

1. It can maintain high efficiency and will not reduce efficiency due to wear.

2.Adopt pressure adjustable design, which can meet the vacuum degree and gas flow rate within a certain range.

3. Smooth operation, low noise and high work efficiency.

4. The parts in contact with gas are made of PTFE material, which has strong resistance to chemical corrosion.

5. It can replace circulating water vacuum pump and rotary vane vacuum pump.

6. Equipped with vacuum adjustment device, which can adjust the vacuum index according to the needs of the experiment.

7. Equipped with a silencer, which can effectively reduce noise.

After-sales service:

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 in tandem 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 and force the four one-way ball valves to open and close alternately, so that the liquid is continuously sucked and discharged.

2. What is the reason for the decrease in the flow rate of the diaphragm vacuum pump?

There is air leakage in the suction pipe, the suction pipe is not immersed in liquid, the diameter of the suction port is small, the end face gap is too large, the pump shaft speed is slow, the filter is blocked, and the pump is worn.
