This paper analyzes the reasons of pneumatic diaphragm pump is the key to the liquid what!

1, be careful not to take the import and export of the pump, the pump is the import, export in. Pneumatic diaphragm pump wear parts, the pump body, and easy to solve this case, change the parts. 2, there are insufficient gas origin of air compressor is too low, Normal pressure is 5 - 7 kg) ; Concentration of liquid density is too large, or too large, the suction of the pump can not reach, so in this case, the pump at work, but not out of the liquid. 3, inlet air pressure is not enough, the general domestic pneumatic diaphragm water pump air pressure range in 2 - commonly 7 kg, greater than or less than the value of the pump can't work normally; The pipeline sealing fluid inlet is not good, so, the water pump is normal work, but because of absorbing liquid, so the pump is out of the liquid. 4, pneumatic diaphragm pump valve ball and seat sealing in the water pump body is bad, with liquid immediately return back again, in this case, the pump body is out of the liquid, but the traffic is very small, very low head. Pneumatic diaphragm pump is a new type of conveying machinery, using compressed air as power source, for all kinds of corrosive liquid, with particles of liquid, high viscosity, volatile, flammable, poisonous liquid, it can be smoked light.
The , essentially perfected by winter cover pump, is one of the first home appliance to be widely distributed.
