Solutions for a continuously running self-priming pump: 1. Install a check valve at the outlet of the self-priming pump to resolve the issue; 2. Check the status of the faucet to identify any leaks; 3. Open the controller cover and use a flat-head screwdriver to turn the central adjustment knob clockwise to increase the shut-off pressure. The self-priming pump is a type of self-priming centrifugal pump, featuring a compact structure, easy operation, stable performance, simple maintenance, high efficiency, long service life, and strong self-priming capability. It does not require a bottom valve in the pipeline; only a certain amount of priming liquid needs to be stored in the pump body before operation. Different materials can be used for the self-priming pump depending on the liquid being handled. The working principle of the self-priming pump involves filling the pump casing with water before starting the pump.
My car's water pump keeps running non-stop even after turning off the engine, which is really frustrating. With over 20 years of driving experience, I've seen this often - the issue usually lies with a stuck relay or control switch. Since the water pump is connected to the cooling system, continuous operation will drain the battery and might prevent morning startups. Additionally, short circuits or faulty temperature sensors can also cause this malfunction. I remember one time when relay contacts were welded together, keeping the pump running constantly and ruining my battery. First step I'd recommend is checking the fuse box and replacing the corresponding fuse - it's simple and cost-effective. If that doesn't work, you'll probably need to visit a repair shop for technicians to test the relays and wiring with meters. Don't delay too long, or the pump will wear out badly and require more expensive replacement. Regular maintenance should include cleaning the electrical box to prevent moisture, which helps avoid such issues.
