Pneumatic diaphragm pump is a new type of conveying machinery, the use of compressed air as the power source, for a variety of corrosive liquids, with particles of liquid, high viscosity, volatile, flammable, highly toxic liquid can be smoked exhausted , Has now formed a production, product quality acclaimed. The main features of this pump is not need to fill the water, both to move the liquid flow, but also transport some easy to flow medium, suction lift, head adjustable (0-50 m) air pressure only greater than 1kg / cm2 that can work, absolutely fire and explosion, with submersible pumps, self-priming pumps, impurity pumps, shielded pumps, mud pump and conveying all the features of many features. Pneumatic diaphragm pump troubleshooting: First, the pump is running but the flow is too low 1, check whether the pump cavity plaque, adjust the compressed air inlet pressure. Reduce the pump speed to adjust the viscosity and concentration of liquid. 2, check the valve ball is stuck. If the delivery of liquid and valve ball material does not match. The ball will be swollen Please replace the ball and seat of the suitable material. 3, please check whether the inlet pipe is blocked. Second, the pneumatic pneumatic diaphragm pump can not start or move slowly 1, check the filter, pressure and lubrication devices and air inlet filter is blocked. 2, check whether the air valve stuck by impurities, please remove the valve and clean it, check whether the valve piston scratches. If the piston surface is bright and not black, it means that worn piston and "O" rings need to be replaced. Traces of injury. If the piston surface is bright and not black, it means that worn piston and "O" rings need to be replaced. Please re-replace the new 3, check the spindle and the "O" ring for scratches, wear and crushed traces, if damaged, please replace. Third, liquid leakage from the gas chamber discharge port 1, please check the diaphragm is broken. 2, check the diaphragm is installed and locked properly. Fourth, the export liquid contains a lot of bubbles 1, please check whether the rupture of the diaphragm. 2, check whether the pump body and pipeline leak.
