Home tap water self-priming pump work in the pressure switch in the contact da da da frequent contact, the water is about what, whether to install the check valve and pressure tank
Set the pressure difference is too small, resulting in frequent start and stop. Check the adjustment of the pressure difference is just fine!
You are the pressure switch problem:
??? 1. It is possible that your pressure switch is not suitable for surge operation of the pump, due to the type of pressure switch used.
??? 2. may be your pump problem, probably because your pump in the water when the water pressure instability.
In fact, you have to consider the sacrifice under which, I suggest that adjust your pressure switch set point to high or low-key can be, that is the current stalls can not, the best advice is to increase some, so you can make the pressure Switch over the peak of the surge, there are very recommended that your pressure switch for the traditional piston diaphragm type, the response surge effect better.
Automatic switch in the spring I have been adjusted, whether to install the check valve and pressure?
To answer
Do not know how your pump is installed, the pump installed in front of the water pipe? Whether the water supply is caused by the municipal pipe network or the kind of water supply in the village? Self-priming pump has a feature that is automatically empty the suction pipe gas. Therefore, if you adjust the pressure difference after the situation you also said that it should check whether the import pipe leak. If the leak pump will work for a while to empt the leak into the steam, the performance is about what time off the water, so check the leak is non-critical, especially the joint seal to carefully check the bolt. You first try to try it! If your home is rural rather than municipal pipe network, then the pipe network will be there, there is trouble. But the check valve is of little significance. Not yet welcome to ask!
