In this embodiment, when the system works, the control box controls the electric ball valve at the water inlet to open, closes the electric ball valve at the water outlet, opens the check valve at the rear end of the on-duty pump, and closes the check valve at the rear of the main pump. When the liquid level of the water tank reaches a high level, the on-duty pump is started in a variable frequency mode, the main pump is in a dormant state, the pressure of the water inlet pipe is detected by the pressure gauge to be maintained at 0.85MPa under the action of the on-duty pump, but the pressure is not limited to 0.85MPa in actual application; the circulating pipe is also provided with a circulating electromagnetic valve which is opened, at the moment, water in the water tank flows into the circulating pipe under the action of the duty pump in the system, the water is in a circulating continuous running state, and the pressure of the water inlet pipe is always maintained at 0.85MPa; the water in the water tank flows through the water inlet pipe, the duty pump and the circulating pipe and then flows into the water tank, so that the water circulates. When the circulation operation reaches the set time or the liquid level of the water tank is higher, the circulation electromagnetic valve is closed, and the duty pump is dormant. When the duty pump is dormant and reaches the set time or the liquid level of the water tank returns to normal, the liquid level of the water tank is monitored to be normal, the circulating electromagnetic valve is automatically opened, when the pressure of the water inlet pipe is reduced to 0.80MPa, the duty pump is awakened and put into variable frequency operation again, and the operation is repeated in such a way, so that the pressure of the water inlet system is maintained at 0.85MPa.
