Abstract
The utility model relates to an automatic switch of a water pump, which belongs to an electric water pump control device. The purpose of the utility model is to automatically control the liquid level in a water tower and automatically monitor the water level in a water well simultaneously. The utility model has the technical proposal that an automatic control circuit is composed of a power supply circuit, a signal processing circuit and a signal circuit, wherein the signal circuit controls the start and the stop of a water pump electric motor after the detection signals of the high and the low water levels in the water tower and in the water well are processed and enlarged respectively by the signal processing circuit. The predetermined altitude of the liquid level in water tower is guaranteed, and water in the water well is prevented from being pumped out. The utility model has the advantages of simple circuit, reliable work, convenient use and installation.
Description
Technical field
The utility model relates to a kind of electric water pump control device, particularly a kind of water pump automatic switch.
Background technology
At present, generally adopt electric water pump that water is evacuated to from well in the water tower in the family of no tap water, use again discharges water, only operation by rule of thumb, can not guarantee to keep certain liquid level in the water tower, often cut off the water supply or the spilling water phenomenon, can not monitor the water level in the well, cause sky to take out easily, functional reliability is poor, uses inconvenience, though also occurred as Automatic Control Components such as transistor liquid level relays, but the control circuit complexity is expensive big.
Summary of the invention
The purpose of this utility model is in order to overcome above-mentioned weak point, can simultaneously liquid level in the water tower to be controlled automatically and provide a kind of, the water level in the well is monitored automatically, reliable operation, water pump automatic switch easy to use.
The purpose of this utility model is to realize like this; The water pump automatic switch comprises shell; the automatic control circuit that it is characterized in that it is made up of power circuit, signal processing circuit, signal circuit, by signal circuit respectively to the detection signal of water tower, well middle water level height the opening, shut down of control of pump motor after signal processing circuit is handled, amplified.
The utility model can be controlled liquid level in the water tower simultaneously automatically owing to adopt above design, and the water level in the well is monitored automatically, and circuit is simple, and reliable operation is easy to install and use, and is economical and practical novel.
