Centrifugal pump in operation, there may be a variety of failures, we use the process, we must learn to repair the pump failure, small series of centrifugal pumps now in the process of possible causes of the malfunction and Approach to tell you. Centrifugal pump First, the pump does not start when the water 1. Did not start before filling or not filled with water. Should stop the pump to re-fill the water. 2. Absorption height is too high p should reduce the water absorption height, so that no more than 6 meters. 3. Suction pipe leaks or bubbles, you should check the suction pipe to eliminate leakage. 4 faucet plug, taps should be cleaned. 5. The number of revolutions is too low, check the power situation. Second, after the start of Tianjin pump displacement is very small 1 impeller inlet blocked by debris, impeller damage or blocked; check the first paragraph of the pump to clean up debris or replace the impeller. 2. Faucet is partially blocked; check clean. 3 suction pipe joints are not tight; check the connector counterparts, tighten or change the pad. Impeller abrasion, mouth ring seal wear too large; check to confirm, replace the mouth ring seal. 5. Pan plate leakage; replace the plate ç» box. Third, the tap suddenly dropped 1. Tap to reveal the water; stop pump. 2. Faucet is blocked; stop the pump clean. Fourth, the motor current is too large 1. Drainage gate at the end of the closure of customs clearance; start attention. 2. Balance ring plate tilt too much or parts have stuck phenomenon; check the interior, the abnormal part of repair. 3. Rotate part of the adjustment is not correct, to the direction of the water absorption string, move too large, so impeller against the mouth ring; first impeller rotor pushed into the water side of the vertex, and should be based on the score examination. 4 on the wheel is not correct or aprons too tight; find treatment. Fifth, the lack of water pipe run too much water run high-pressure water 1. Balance disc sleeve and water jacket gap to expand; check the process, if necessary, replace one of the parts. 2. Improper assembly of the rubber gimbal ring, not being braced or stepped up the ring, rubber band rope in the tight circle without adding; remove the bracket, reassemble the balance ring. Sixth, pump vibration during operation 1. Tianjin pump and motor center is not right; check and adjust. 2. The pipe is not fixed properly; check and adjust. 3 bracket bearing gap; check adjustment. 4 axis bending; maintenance, replacement of the new shaft.
