Embodiment Construction

[0019] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:

[0020] Such as Figure 1 to Figure 3 As shown, the water pump automatic control device of the present invention includes a housing 1, which is divided into two upper and lower chambers separated from each other by a diaphragm 2 inside the housing 1, which are respectively an upper chamber 3 and a lower chamber 4. , the diaphragm 2 is located at the top of the lower cavity 4 .

[0021] The housing 1 is provided with a water inlet 6 and a water outlet 7, the water inlet 6 is connected to the water outlet of the water pump (not shown in the figure) through a water pipe, and the water outlet 7 is connected to the water inlet of the water-using equipment through a water pipe. In this embodiment, the water inlet 6 and the water outlet 7 are in communication with the lower cavity 4, and the water pumped out enters the lower cavity 4 through the water ...

Abstract

The invention relates to an automatic control device for a water pump, which comprises a casing, on which a water inlet and a water outlet are arranged, and the interior of the casing is divided into two chambers separated from each other by a diaphragm, which are respectively An upper chamber and a lower chamber, the lower chamber communicates with the water inlet and the water outlet, a magnetic float is arranged in the lower chamber, and a corresponding magnetic switch is arranged on the outer wall of the housing , a pressure regulating device is arranged in the upper cavity, and the pressure regulating device is connected with the diaphragm. The invention has the advantages of simple structure, high integration, small space occupation, simple and convenient control, and realizes functions of water shortage protection and automatic start and stop of water pumps by using a set of magnetic floats and magnetic sensitive switches. The setting of the diaphragm has the function of maintaining the pressure of the water outlet. At the same time, the device is non-contact, and the electric control device and detection parts are not in contact with water, which is more reliable.

Description

technical field [0001] The invention relates to a water pump control device, which belongs to the technical field of water pump control. Background technique [0002] At present, the automatic control of the water pump generally adopts the pressure switch, the flow switch, and the water level detection of the water source to control the start and stop of the water pump. Directly use the pressure switch to start and stop, because the pipeline cannot maintain the pressure, frequent start and stop phenomenon occurs. In order to solve this problem, there is a method of adding a compressed air tank in the water outlet pipeline, but the system has a complex structure and many parts, and takes up a lot of space. Contents of the invention [0003] The main purpose of the present invention is to solve the above problems and deficiencies, and provide an automatic water pump control device with high integration, small space occupation and simple and convenient control. [0004] For...
