What is the repair method for a self-priming pump that keeps running without stopping?

[StLilliana]

Self-priming pump that keeps running without stopping repair method is: promptly check whether there is water leakage in the outlet pipe, locate the leakage position, repair or replace it to ensure normal operation. The working principle of the self-priming pump is: before starting the pump, fill the pump casing with water first. After starting, the high-speed rotation of the impeller causes the water in the impeller channel to flow toward the volute, creating a vacuum at the inlet, which opens the inlet check valve, allowing air in the suction pipe to enter the pump and reach the outer edge through the impeller channel. Precautions for using a self-priming pump include: 1. After the entire pump body is fixed, steel pipes can be used to connect to the pump's inlet, and the bottom valve of the self-priming pump needs to be perpendicular to the horizontal plane to ensure normal use later; 2. To prevent electric shock accidents, necessary protective measures should be taken.
