Pneumatic diaphragm pump is a new type to transport a variety of corrosive liquids, with particles of the liquid known for high viscosity, volatile, flammable, highly toxic liquid can be smoked exhausted , Can be described as the emerging domestic pump "a good hand." However, the user will find that after using for a period of time, the user may find that there is a problem that the pump pumping speed will be slowed down, the flow rate will be reduced, and the pump will not work. So why do these faults occur? Hope that your equipment repair provide some help. Pneumatic diaphragm pump common fault and analysis of the reasons First, the pneumatic diaphragm pump common fault analysis 1. pump pumping speed is slowed 2. pump flow reduction 3. pump does not work 4. material impurities or oil 5. pump import and export Leakage II, the reasons for the common problems of pneumatic diaphragm pump 1. Pump pumping speed slowed mainly due to its reduced gas pressure, silencer blockage, excessive air or impurities in compressed air and the inner four ring seal wear While the string of gas caused; 2. Pneumatic diaphragm pump flow reduction occurs mainly with the import and export of one-way valve (plastic ball) wear and tear less, the diaphragm often stretch deformation and the thick layer of black film that is damaged; 3 The main reason for the pump is not working: severe wear and tear valve spool; shaft sleeve wear; shaft at both ends of the screw drop and the two films are broken. 4. Diaphragm rupture lead to material impurities or oil; 5. Screw is not fastened or the ball seat deformation or O-ring damage will have the phenomenon of leakage of the import and export. The above is the screw pump common fault and its analysis, I hope your product repair to provide some help. This article is copyrighted industry interconnect (Xiamen) Co., Ltd.
