I use the pressure switch to control the pressure of the storage tank, keep at about 8 kg, what type of pressure switch? Please write a specific model, it is best to be the kind of common, and that is, I think the pipeline on a pump a pressure switch seems to have a lot of drawbacks, may I need to increase what? Such as flow switches and the like
Recommended direct use of electrical contact pressure gauge, both can see the pressure can also be achieved control.
Pressure switch is not recommended
The best control is the frequency converter + pressure transmitter to achieve PID constant pressure control
Export plus check valve on it, even if there is pressure, it will not return to water! Will not affect the pump seal.
Pressure gauge pressure is usually set a pressure, it can be slightly larger, it will not start frequently.
Pump is best two, one with a prepared, bad one okay maintenance, does not affect the use. Do not need to add the flow switch, the outlet should have a check valve and gate valve, the other does not need.
Installed an electrical contact pressure gauge on the line, not expensive, low pressure start, high pressure stop pump.
