As further scheme of the invention: the access hole is equipped with maintenance door；The maintenance door is solid by bolt
It is scheduled on access hole；The maintenance door is equipped with maintenance handle；The maintenance handle is welded in maintenance door.
A kind of supply and drain water system using above-mentioned paint spray booth's water supply self-priming apparatus.
Compared with prior art, the beneficial effects of the present invention are:
1, the present invention replaces bottom valve by self-priming apparatus, reduces sewage backflow phenomenon caused by due to bottom valve leakage and influences water
The problem of pump operation.
2, after the present invention is by preventing sewage backflow, the operation filled the water before the water pump starting of cancellation into water pump is realized
The automation control of water pump.
3, the present invention solves the problems, such as bottom valve corrosion, eliminates the construction of traditional underground pump station, has saved underground pump
The construction cost stood.
