Question:

Electric water pump goes on for 1 second then completely off?

I live in a house that uses a pump to push water from a tank to the bathroom and kitchen. It has a sensor that detects if water is flowing and pushes it much harder. Recently, it has been pushing the water for a second or less then it completely stops for a while. It's like a pulse of water then nothing. Can anyone give me feedback on what is wrong here? Thank you.

Answer:

from okorder :Self-priming pump working principle is: the pump before you start in the pump shell filled with water (or) from the water in the pump housing.Start after high-speed rotating impeller flow to the vortex in the impeller, shell, then the entry form the vacuum, the inlet non-return door open, within the air into the pump suction tube and the impeller, to arrive at the outer edge.Self-priming pump is a self-priming centrifugal pump, it has compact structure, convenient operation, stable operation, easy maintenance, high efficiency, long service life, and have strong self-priming capacity, etc.Line does not need to install the bottom valve, only to ensure storage in pump body before work are quantitative liquid.Pump after the normal starting, impeller liquid of suction chamber and inlet line of air suction, and can completely mixed within the impeller, the function of centrifugal force, and liquid with gas to the vortex flow volume outside edge, the impeller has a certain thickness is formed on the outer edge of the white foam belt and high-speed rotating liquid ring.Gas-liquid mixture into the gas-liquid separation chamber through diffusion tube.At this time, due to the flow rate suddenly drops, lighter gas is separated from the mixture of liquid and gas through the pump body spit continues to rise.After degassing of liquid to liquid storage chamber, and the reflux hole again into the impeller, and impeller with inhalation of gases from the inlet line again mix, flow under the action of the high-speed rotating impeller and the impeller outer edge....As the process cycle, decreasing the air in the suction line, until all gas absorption, complete the self-priming process, pump put into normal operation. What you said phenomenon should be pipeline leak, which leads to the self-priming pump process is repeated.
