逆止弁１０を経て給水管９へ圧送される。As the plunger pump 1, for example, one having a discharge water rate of 40β/min and a discharge pressure of 40 kg/cJ is used. The pressure switch 11 is configured such that the water supply pressure in the water supply pipe 9 is a set pressure (for example, 12 kg/c++I
) The pressure switch 13 is a normally closed switch that turns OFF when the pressure exceeds Iu.
According to the configuration described above, which is a normally closed switch that turns OFF when the above conditions occur, the check valve 10 is
The water supply pipe 9 side ahead is empty and there is no water flow in the spill pipe 12, so the pressure inside both the water supply pipe 9 and the spill pipe 12 is below the set pressure. Therefore, since both pressure switches 11 and 13 are in the ON operation state, when the automatic operation switch 0 is turned on, the electromagnetic switch 29 is energized, the motor is operated, and the Granger pump 1 is driven. As a result, the water in the water tank 8 is sucked in through the water suction pipe 6, pressurized, and sent under pressure to the water supply pipe 9 via the check valve 10.

5 is closed, the entire water supply channel including the water supply pipe 9 and the pressure-resistant hose 18 is filled with water, and as a result of the pressure-resistant hose 18 being slightly expanded, the pressure in the water supply channel increases to the pressure regulating valve 5.
When the discharge pressure exceeds the maximum discharge pressure set in , the water discharged from the plunger pump 1 flows out to the spill pipe 12 via the pressure regulating valve 5 . As a result, the pressure inside the spill pipe 12 exceeds the set pressure, and the pressure switch 13 turns OFF! Therefore, the electromagnetic switch 29 is demagnetized and the operation of the plunger pump 1 is stopped. plunger pump 1
When the operation of
It returns to the N operating state, but the self-holding A contact 29a is already closed.
has been switched to the OFF state, and the pressure switch 11 is naturally in the OFF state since the pressure in the water supply pipe 9 is set to -1:, so the demagnetization state of the electromagnetic switch 29 continues. , the pump 1 is not driven again.
