Summary of common faults and treatment methods of metering pumps

Treatment Borewell Pumps Manufacturers for reduced measurement accuracy: (1) Same as (4)~(11) in No. 3.. (10) The motor speed is insufficient or unstable; treatment measures: stabilize the motor speed. (2) Air leakage in the suction pipeline; treatment measures: seal the leaking part tightly. (15) The motor does not rotate; measures: check the power supply, check whether the fuse and contact are good. (12) The filter is blocked; treatment measures: dredge the filter.

Summary of common faults and treatment methods of metering pumps 1. (6) Air leakage or oil leakage in the supplementary valve group or diaphragm cavity; treatment measures: find out the leaking location and seal it tightly. Treatment methods for inability to discharge or insufficient discharge: (1) The suction pipe is blocked or the suction pipe valve is not opened; treatment measures: check the suction pipe and filter , Open the valve. (3) The diaphragm or discharge pipe joint is not tightly sealed; treatment measures: find out the leaking part and seal it tightly. (2) The zero point of the plunger drifts; treatment measures: readjust the zero point of the plunger. (5)

Residual gas in the diaphragm cavity; treatment measures: refill the oil to remove the gas. Treatment methods for pump pressure not reaching performance parameters: (1) The suction and discharge valves are damaged; treatment measures: replace with new valves. Treatment methods for parts overheating: (1)

Force the pump shaft in one direction, causing the shaft to bend. In the early stage of trial operation, the fluid is dirty or the viscosity is too high, which is prone to cavitation and vibration. A pump with a bent shaft will cause the impeller and other transmissions to be unbalanced during operation, resulting in friction between the impeller and the casing, resulting in vibration of the pump. When the flow of the large valve is normal, the vibration will disappear. 4. , If there is a disagreement, you can only stop the machine and realign it. used in the coupling are easily damaged. Replace the damaged rubber ring to restore normal. One is different.
