Water pump structure for controlling self-start and self-stop through flow and using method thereof

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...

[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 does not need it, which will bring unnecessary trouble to the user. And the life of the water pump is reduced, it is very necessary to design a new water pump structure in order to solve the above technical problems
