Reasons why the pneumatic diaphragm pump crashes and does not work
The reasons why the pneumatic diaphragm pump crashes and does not work are:
1. Because the air source coming out of the air compressor is not clean, and the air source inlet of the pneumatic diaphragm pump is not equipped with an air filter, the air source contains some moisture, causing the moisture to enter the air distribution valve, because the piston inside the air distribution valve moves up and down. For sliding work, due to the incoming moisture, the gas distribution valve becomes stuck after splashing water, resulting in the pneumatic diaphragm pump crashing. The solution is to install an air filter at the air source inlet of the pneumatic diaphragm pump.
2. The old stainless steel pneumatic diaphragm pump is used. This pneumatic diaphragm pump product still uses an external air distribution valve. Due to the relatively large dust in the environment, the pneumatic diaphragm pump has been running in an environment that is not full of dust for a long time, and the dust has penetrated into the distribution valve. The air valve contaminates the piston cavity of the air distribution valve, causing the air distribution valve to get stuck. To avoid this phenomenon, it is recommended to use the third or fourth generation pneumatic diaphragm pump products of Boyu Company, because this type of product is equipped with The air valves all adopt a built-in air distribution valve design structure, which completely seals the air distribution valve device in a closed environment, so there will be no jamming of the air distribution valve.
3. The diaphragm of the pneumatic diaphragm pump is damaged due to long-term reciprocating operation or the diaphragm is damaged due to liquid corrosion and excessive air supply pressure. The solution is to replace the diaphragm with a new one or a diaphragm that is more suitable for the corrosive medium and adjust the air supply pressure.
4. The air supply pressure is too low or the air supply volume is not enough to meet the standard requirements for the operation of the pneumatic diaphragm pump. Solution: Adjust the air source pressure and flow to meet the standard requirements.
5. The outlet valve of the pneumatic diaphragm pump is closed and forgotten to be opened, causing the pneumatic diaphragm pump to fail to operate normally. The solution is to open the outlet valve.
