Electric pump with controller and control method of electric pump

Abstract

The invention relates to an electric pump with a controller and a control method of the electric pump. The electric pump is characterized by comprising an electric pump body and the controller connected with a water outlet of the electric pump body. The controller comprises a shell body, a controller body arranged inside the shell body in a sealing mode, a water outlet section and a connection pipe, wherein the water outlet section and the connection pipe are communicated with a hollow inner cavity of the controller body, penetrate through the shell body and are sealed with the shell body, and the connection pipe is connected with the water outlet of the electric pump body. The electric pump with the controller and the control method of the electric pump have the advantages that components and parts having the control function are arranged inside the controller body and are connected with the electric pump body only through the water outlet section and the connection pipe, so that the number of connectors is reduced; the controller body can control the operation of a water pump and protect the operation of a motor by comprehensively combining the related working parameters of the motor and the water pump, and can protect the electric pump and the motor at the same time.

Description

technical field [0001] The invention relates to an electric pump and a control method, in particular to an electric pump with a controller and a control method thereof. Background technique [0002] Household electric pumps are used for water supply boosting, and the electric pumps realize intelligent automatic operation and fault protection through the controller; operation involves boosting, pressure maintaining, self-priming, and shutdown; protection involves dry running without water, frequent startup of system leakage, motor stall or Overload, anti-icing, water temperature detection and other fault identification; the current control method and controller have not comprehensively integrated the work-related parameter variables of the motor and the pump to control the operation of the pump and protect the motor, and there will be faults that cannot be identified during operation. Failure to play a protective role and other issues. [0003] The controllers used for the e...

[0002] Household electric pumps are used for water supply boosting, and the electric pumps realize intelligent automatic operation and fault protection through the controller; operation involves boosting, pressure maintaining, self-priming, and shutdown; protection involves dry running without water, frequent startup of system leakage, motor stall or Overload, anti-icing, water temperature detection and other fault identification; the current control method and controller have not comprehensively integrated the work-related parameter variables of the motor and the pump to control the operation of the pump and protect the motor, and there will be faults that cannot be identified during operation. failure to protect

[0003] The controllers used for the existing electric pumps are mostly control boards, flow switches, pressure switches, pressure tanks, pressure gauges, etc. connected to the pump body through five-way. More connecting holes, working vibration will easily lead to leakage, causing frequent system start-up failures, causing inconvenience to normal operation and maintenance; in addition, each component is installed on the pump body separately, making installation inconvenient and increasing assembly costs
