What are the precautions for dismantling pneumatic diaphragm pump：
Pneumatic diaphragm pump in the installation of the need in some special occasions, in general, some of the conventional pump pumping is not able to carry out the suction medium, so have got a better use effect. Removing old diaphragm pumps is often a hassle. So what do you know to replace the pneumatic diaphragm pump?
Dismantling pneumatic diaphragm pump should be noted as follows:
1. Pull the hydraulic end outward to make the screw free from the jack. Grab the liquid and turn it counterclockwise.
2, the suction end of the metering pump may leak. Hydraulic end suction side coupling reduces loose o - ring or suction valve connections.
3. After loosening the pump head, adjust the travel length to 10% azimuth Angle before removing the pneumatic diaphragm pump head. To ensure that the electromagnetic shaft has satisfactory pressure, insist that its connection is stable so that the diaphragm can be unscrewed.
4, metering chemicals may crystallize in the hydraulic end, resulting in the ball and seat of the check valve can not work normally.
Pneumatic diaphragm pump in the work is the use of compressed air as the power of equipment, diaphragm in the process of reciprocating deformation is very easy to appear volume change, its main working principle is very close to the plunger pump.
Dismantling pneumatic diaphragm pump should pay attention to the main points introduced above, we all need to pay more attention to these points of attention.
