LZW self - control sealing self - priming sewage pump failure and troubleshooting

In daily use, LZW self-priming non-self-priming sewage pump will inevitably fail, then LZW self-priming pump without sealing self-priming sewage pump What are the common problems? In the event of failure, and how to proceed Exclude it? Next, introduce you to LZW self-sealing self-priming sewage pump failure and troubleshooting. LZW automatic seal-free self-priming sewage pump common fault and troubleshooting methods, the motor does not rotate (a). Reason: 1 .. The motor has been damaged; 2. Power is not available; (b). Remedy: 1. Repair or replace the motor; 2. Check that the power is on. Second, the pump is not liquid (a) reasons: 1. inadequate drainage; 2. suction side of a flange, valves or piping a large number of leaks; 3. drain or vent mouth fight cap is not tight, or No gaskets inside the cap; 4. No liquid in the tank or tank. (B) the exclusion method: one by one inspection, for exclusion. Third, the process, head (pressure) does not meet the standard (a) reasons: 1. Voltage is too low, rated speed can not reach; 2. Motor reversal; 3. The bottom of the filter block, Only flanges, valves or somewhere in the pipeline chronic leakage, affecting the pump vacuum; 5. The container or tank liquid too little, sometimes sucked into the air. (B) the exclusion method: one by one inspection, for exclusion. Fourth, the motor and the pump connection site leakage (a) reasons: 1. start instantaneous leakage, the phenomenon disappears after normal operation; 2. run-time leakage (may be the sealing device is damaged, or the actual head pressure and the water pump Big differences in parameters). (B) the exclusion method 1. The infusion of fluid overfilling, not a fault; 2. Check the seal is damaged, recalculate the actual working pressure exceeds the pump specified parameters; If the seal has been damaged, please consider repairing or replacement: Pressure parameters are too different, please consider re-select or adjust the actual working pressure.
