Automatic self-priming pump pressure switch how to tune
It should be automatic pressure control switch is broken, for a will be good, my family is the case! My home switch is very easy to bad, really headache, check and find out what the problem
The pressure to adjust the place in the spring that place. But pay attention to safety
The pressure switch to reduce the maximum pressure of the minimum increase and fall between the upper and lower interval of 0.5 pressure on the line after the minimum water closing water off the maximum disconnection.
Self-priming pump works is: before the pump starts in the pump casing filled with water (or pump itself with water). After the start of the high-speed rotation of the impeller so that the impeller channel flow of water to the volute, then the entrance to form a vacuum, so that the water back door open, the suction pipe into the pump, and impeller channel to the outer edge. Self-priming pump is a self-priming centrifugal pump. It has the advantages of compact structure, convenient operation, smooth operation, easy maintenance, high efficiency, long life and strong self-priming ability. Pipeline do not need to install the end of the valve, just before the work to ensure that the pump can be stored within the quantitative solution can be. Different liquids can use different materials from the suction pump.
