Embodiment Construction

[0020] The present invention will be further described in detail below in conjunction with the drawings and specific embodiments:

[0021] Such as Figure 1 to Figure 3 As shown, the automatic control device for a water pump of the present invention includes a casing 1, and the inside of the casing 1 is divided into two upper and lower chambers separated from each other by a diaphragm 2, which are an upper chamber 3 and a lower chamber 4, respectively. , The diaphragm 2 is located at the top of the lower cavity 4.

[0022] 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 a 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 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 from the water pump enters the lower cavity 4 through the wat...

Abstract

The invention relates to an automatic water pump control device which comprises a shell body, wherein a water inlet and a water outlet are formed in the shell body, the interior of the shell body is divided into an upper containing cavity and a lower containing cavity through a membrane, the upper containing cavity is separated from the lower containing cavity, the lower containing cavity is communicated with the water inlet and the water outlet, a magnetic floater is arranged in the lower containing cavity, a corresponding magnetic-sensing switch is arranged on the outer wall of the shell body, a pressure adjusting device is arranged in the upper containing cavity, and the pressure adjusting device is connected with the membrane. The automatic water pump control device is simple in structure, high in integration degree, small in occupied space, easy and convenient to control, and capable of achieving water lack protection and automatic starting and stopping of a water pump by means of a set of magnetic floater and magnetic-sensing switch. The arrangement of the membrane enables the pressure of the water outlet to be maintained. Meanwhile, the automatic water pump control device is a non-contact type device, electrically-controlled devices and detection parts are not in contact with water, and therefore the device is more reliable.

Description

Technical field [0001] The invention relates to a water pump control device, belonging 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. The pressure switch is directly used to start and stop, because the pipeline can not maintain the pressure, frequent start and stop phenomena occur. In order to solve this problem, a method of adding a compressed air tank in the water outlet pipeline is adopted, but the system has a complicated structure and many parts and takes up a large space. Summary of the invention [0003] The main purpose of the present invention is to solve the above-mentioned problems and shortcomings, and provide a water pump automatic control device with high integration, small space occupation and simple and convenient control. [0004] In...
