Reasons and solutions for self-priming pump not getting water

The reason why the self-priming pump is not watered and its solution:

1. The voltage is too low: Adjust the voltage 2. The suction stroke is too high or the suction line is too long: Reduce the suction stroke or shorten the tubing 3. The mechanical seal leaks too much: Repair or replace 4. The inside of the pump or the inlet pipe filter is Contaminated stone blockage: Check to clear the blockage 5. Self-priming pump is not filled with fluid or insufficient fluid: Add foot 6. Impeller damaged or worn: Replace new impeller 7. Incorrect installation of outlet pipe elbow : Too many pipes with N-shaped pipe It is recommended to install an automatic exhaust valve at the highest point.

8. Three-phase motor connection reversed: interchange two phases.

9. The self-priming pump is blocked by the return hole, resulting in the inability of the soda to separate: Check to remove it.

10. Inhalation line leak:: eliminate leaks in the pipeline, in the range of allowable suction range inspection method Pump start 4-5 minutes water has not sucked up Please use the ear close to the import pipeline suspected leaking place Inspiratory sounds, or patching of white latex at suspected leaks.
