China wholesale deep well borehole pumps

Diaphragm pump is also known as control pump in the industry. It is the main type of actuator. Diaphragm pump is a device that changes fluid flow by receiving the control signal output by the modulation unit and using power operation. It is generally composed of actuators and valves. Its power source is: compressed air, which can absorb all kinds of corrosive liquids, liquids with particles, high viscosity, volatile, flammable, and highly toxic liquids.

It is a kind of equipment with strong practicability and operability. It is easier for the diaphragm pump to be unable to beat the pressure during its work. Next, the main reason for this situation will be analyzed. Diaphragm pump can't hit the pressure analysis: 1. The stroke regulator of the pump is damaged, resulting in useless work. 2. The check valve at the inlet and outlet of the pump is not well sealed. 3.

The outlet pressure is too high, causing the pump to hold back pressure. 4. The inlet filter is blocked. 5. Too little hydraulic oil in the pump. 6. If the pump is provided with a crossover at the inlet and outlet, whether the hand valve is not closed tightly. 7. The outlet pipeline is blocked. When the diaphragm pump is working, when the metering pump just starts to work, the volume is relatively small. Only a stream of rhythmic liquid flowing out of the vent valve at the pump outlet indicates that the pump is good.

These are to ensure China wholesale deep well borehole pumps body is filled with liquid. When the centrifugal pump is started, if there is no filling in the pump or the filling is not full, there will be Air, due to the low density of air, the centrifugal force generated after rotation is small, so that the low pressure formed in the center of the impeller is not enough to suck the liquid in the storage tank into the pump. Even if the centrifugal pump is started, the liquid cannot be delivered.
