> If the air compressor source is too low, the air volume will be insufficient (normal air pressure is kilograms)
If the liquid specific gravity is too large, or the concentration is too large, the suction lift of the pump cannot reach So in this case, the pump is working, but the liquid cannot be pumped out
. The valve ball and ball seat in the pump body of the pneumatic diaphragm pump are not well sealed, and the pumped liquid flows back immediately. In this case , the pump body discharges liquid, but the flow rate is very small and the head is very low
The liquid inlet pipe is not sealed well. In this case, the pump works normally, but because it cannot absorb liquid, the pump cannot pump out. For liquids
, the air source pressure at the air inlet is not enough. Generally, the air source pressure range of domestic pneumatic diaphragm pumps is generally within the range. If it is greater than or less than this value, the pump cannot work normally
. The air source pressure in the pneumatic diaphragm pump body The wearing parts are worn. In this case, it is easier to solve the problem. Just replace the wearing parts. The lowest mistake is to connect the inlet and outlet of the pump backwards. The pump inlet is at the bottom and the outlet is at the top. The probability of this kind of error is very small, but I have encountered such customers.
, stones, plastic bags, and other hard objects are blocked in the ball cavity, causing the ball to get stuck and not return.
