Pneumatic diaphragm pump common operating problems to solve

What if the burden of the pneumatic diaphragm pump is suddenly reduced? In general, this is also caused by insufficient supply of oil. Propose that technical professionals repair the oil pump immediately. It may also be due to the failure of the raw material when feeding, or the phenomenon of oil leakage, and the specific situation of the material needs to be checked immediately to manipulate the oil leakage.

It may be that in the application of pneumatic diaphragm pumps, the worker often finds that the collapse does not move, or the effect is relatively slow. In fact, this is also a widespread phenomenon, so please don't fret. This phenomenon may be that the air valve is stuck, the air valve is worn, the air valve is stuck and cleaned immediately. Ability to apply a cleaning solution. Air valve should be replaced with a new one.

1, the pneumatic diaphragm pump is weak, the pump efficiency is reduced

This phenomenon generally has the following categories of conditions, one is the reduction of standard air pressure. First look at the working pressure of the inlet barometer, the working pressure value of 4-7KG is conventional. Then check the opening part of the pneumatic valve. If a relay is used to open and close the pneumatic valve, check that the plastic valve of the relay is not damaged, causing the plastic valve to fail to open. The second factor is that the muffler is blocked, and the gas cannot be discharged quickly, resulting in a reduction in the vacuum rate. Third, air compression includes a lot of water or residue. After entering the diaphragm pump air valve chamber, wear will prevent the normal repeated movement of the piston rod and small roller. Fourth, because of the continuous impact of the standard air pressure, the single flow valve seal ring of the valve chamber leaks. Fifth, the inner shaft seal ring of the pump is worn and the steam body is leaked.

2, reduce the total flow of pneumatic diaphragm pump


This kind of phenomenon generally has the following types of conditions, one is that the import and export trade check valve wear less. Or there are bars, large particles blocking the ball. As a result, when the material is liposuction, the liquid material discharged out of the inlet is refilled, and when the material is expelled, the material is pressed back from the material channel. Second, the pulse damper is prolonged and deforms, which causes the size of the material cavity to shrink. The third is dark blue. The thick pulse damper is broken. When pushing, the bottom support frame does not move.


3, pneumatic diaphragm pump is not working


This phenomenon is likely to occur in several ways. The piston rod and V-ring in the valve chamber are severely worn and stuck. Second, the shaft sleeve of the bottom support frame has been worn, and the shaft sleeve should be replaced at this time. Third, the inner pin at both ends of the pump shaft is damaged. Fourth, both diaphragms split. Fifth, the diaphragm pump is reversed or put straight.


4, there is debris or oil in the material


This is usually caused by the split of the diaphragm of the pneumatic diaphragm pump. If you see such a situation, you should immediately turn off the pump inlet, stop working and replace the diaphragm. It is proposed that if volatile substances are transported, inflammable, flammable and highly corrosive liquid, the diaphragm should be replaced on time to prevent environmental pollution and unnecessary damage, and ensure that the diaphragm pump has a good working natural environment for a long time.
