Problems solved by technology

[0002] In the past, the water pump basically relied on the pressure switch to control the start and stop of the motor. For example, the motor stops when the set maximum pressure value is reached, and the water pump starts when the set minimum pressure value is lower than the set minimum pressure value. During the user's use, there are often: water pumps and pipelines The original requirements can also be achieved during the initial installation. After a period of use of this structure,

Example Embodiment

[0013] The present invention will be further explained below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. In addition, it should be understood that after reading the teachings of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the appended claims of this application.

[0014] The embodiment of the present invention relates to a water pump structure that controls its own start and stop by flow, such as figure 1 As shown in —2, it includes a water pump body 1, a water outlet pipe 8 and a pressure tank 4. The inlet end of the water pump body 1 is equipped with a water inlet pipe 2, and the outlet end of the water pump body 1 is connected with the outlet pipe 8 and the pressure tank 4 Are connected to each ot...

Abstract

The invention relates to a water pump structure for controlling self-start and self-stop through a flow and a using method of the water pump structure. The water pump structure comprises a water pumpbody, a water outlet pipe and a pressure tank, wherein a water inlet pipe is installed at the inlet end of the water pump body, the outlet end of the water pump body is in butt joint with the water outlet pipe and the pressure tank through connectors, a flow switch is installed in the end, connected with the water outlet pipe, of the connector, the flow switch is electrically connected with a controller on the water pump body, a selector switch is installed on the controller, and the selector switch is provided with three gears such as a manual gear, a stop gear and an automatic gear which canbe switched manually. The water pump structure has the characteristics of simple structure, convenience in installation, long service life, low fault probability and the like.

Description

technical field [0001] The invention relates to the technical field of water pump structures, in particular to a water pump structure and its use method which can be started and stopped by flow control. Background technique [0002] In the past, the water pump basically relied on the pressure switch to control the start and stop of the motor. For example, the motor stops when the set maximum pressure value is reached, and the water pump starts when the set minimum pressure value is lower than the set minimum pressure value. During the user's use, there are often: water pumps and pipelines The original requirements can also be achieved during the initial installation. After a period of use of this structure, the pipeline material will age, so that the structure will always have local leakage, which will cause the pressure in the pipeline to slow down. Decrease slowly until it drops to the set minimum pressure value, and finally the motor will start automatically when the user...
