Treatment methods for serious seal leakage (1) Improper selection of sealing element materials; treatment measures: re-select and replace suitable seals.Common faults and treatment methods of centrifugal pumps 1. Treatment method of motor overload (1) Pump and prime mover are not aligned; treatment measures: adjust the pump and prime mover's alignment. (3) Use a head higher than the pump head; treatment measures: replace the pump with a higher head. (6) The filter at the suction end is blocked; treatment measures: clean the filter. (4) The inlet or outlet valve is not fully opened; treatment measures: fully open the valve.. (5) Air leaks into the suction pipeline; treatment measures: block the leak. (3)The number of revolutions is insufficient; treatment measures: increase the speed as required. (5) Vibration; treatment measures: check the balance of the rotor or operate at a small flow. 2. Treatment methods for bearing heating (1) Too much lubricating oil; treatment measures: reduce oil. (3) The rolling bearing of the pump or motor is worn; treatment measures: replace the bearing. (4) The unit is not in agreement; handling measures: check and adjust the alignment of the pump and the prime mover. (2) The inlet or outlet pipe valve is closed or the blind plate is not removed; treatment measures: open the valve or remove the blind plate. (7)The density of the medium does not meet the requirements of the pump; treatment measures: re-calculate or replace the motor with suitable power. (8) Rotation speed does not match; Treatment measures: make the motor speed meet the requirements. (8) The device head does not match the pump head; treatment measures: change the impeller diameter or replace (check Sewage Pumps Manufacturers whether the motor rated power is satisfied). (9) The pump rotation direction is wrong; measures: check and adjust the pump rotation direction. 3. (6) The suction height is too high; treatment measures: reduce the pump installation height and increase the pressure at the inlet. (5) Wrong direction of rotation of the impeller; treatment measures: correct the rotation of the motor. (2) Too little lubricating oil; treatment measures: add oil. Treatment measures: Reinforce the base or tighten the anchor bolts. (2) The friction pair is severely worn; treatment measures: replace the worn parts and adjust the spring pressure. 5. (2) Excessive wear of the sealing ring; treatment measures: replace the sealing ring. (3) Friction occurs in the rotating part; treatment measures: repair the friction part
