Water pump controller convenient to adjust

Abstract

The invention discloses a water pump controller convenient to adjust. The water pump controller convenient to adjust comprises a shell provided with a water inlet connector and a water outlet connector and a control circuit board. The shell comprises a pressure cavity and a pressure maintaining device connected with the pressure cavity. The water inlet connector and the water outlet connector communicate with the pressure cavity. The shell is further internally provided with a pressure sensor and a flow sensor which are electrically connected with the control circuit board. When the flow signal value output by the flow sensor is less than or equal to a set shutdown flow value, the control circuit board outputs a shutdown signal to a water pump, and the pressure maintaining device maintainsthe water pressure of the pressure cavity in a water pump shutdown state. When flow is formed at the water outlet connector, the pressure maintaining device enables the water pressure of the pressurecavity to decline gradually. When the pressure signal value output by the pressure sensor is less than or equal to a set startup pressure value, the control circuit board outputs a startup signal tothe water pump. The water pump controller convenient to adjust can effectively reduce the starting frequency of the water pump, remain the pressure of a water supply pipe stable and meanwhile ensuresthat the water supply amount of the water pump is matched with the requirement of a demand side.

Description

technical field [0001] The invention relates to the technical field of water pump control, in particular to a water pump controller with convenient adjustment. Background technique [0002] In the existing water pump water supply system, in order to realize the normal operation and automatic control of the water pump, it is usually necessary to configure a pressure controller for controlling the running state of the water pump. The pressure controller usually includes a plastic shell. The shell is provided with a water inlet port and a water outlet port that can be connected to the water supply pipeline. The shell is provided with a pressure chamber communicating with the water inlet and outlet, and a pressure chamber Sealed and separated sealing chambers, a pressure sensor capable of detecting water pressure is arranged in the pressure chamber, and a corresponding control circuit board is arranged in the sealing chamber. When the water pump starts to work, the pressure cha...
