The hot water circulation pump is widely used in: energy, metallurgy, chemical, textile, papermaking and other fields. The hot water circulating pump mainly has the following failures: no water, insufficient flow, murmur vibration, and leakage of water. Here are common problems and countermeasures, hoping to help users.

1. What should I do if the hot water circulating pump does not produce water?

1. The entrance valve of the thermal pump was not opened, the entry and exit pipeline was blocked, and the abortion impeller was blocked. Solution to remove obstructions.

2. Insufficient import and export water supply, high suction, bottom valve leak water. Disclosure and adjustment (this phenomenon is easy to occur from the water pipe and the inhalation of the side of the grid).

3. The pump is not filled with liquid, and there is air in the pump cavity. Open the cover or open the exhaust valve to discharge the air.

4. Hot water circulating pump inhalation tube leakage. Tighten each cover to rule out the air.

5. The direction of the motor is wrong, and the speed of the motor is very slow. Adjust the direction of the motor and the sturdy motor wiring.

6. Excessive resistance of pipelines, improper selection of centrifugal pumps. Reduce the tube curve and re -select the pump.

Second, hot water circulating pumps are insufficient?

1. The import and export valve of the hot water circulation pump is not opened, the entry and exit pipe is blocked, and the abortion impeller is obstructed. Solution to remove obstructions.

2. Pipelines and hot water circulation pump pumps are blocking the impeller of the impeller, scale deposition, and insufficient valve opening. Remove the obstruction and adjust the openness of the valve.

3. Use the rated traffic. Adjust the traffic off the small outlet valve.

4. Demodes of the impeller. Replace the leaf wheel.

5. The voltage of the centrifugal pump is low. Stabilize.

6. Pump bearing for wear. Replace the bearings.

7. The suction of the centrifugal pump is too high. Reduce suction.
