Abstract
The invention discloses a corrosion prevention device for a main shaft of a motor of an electric water pump. The device is connected in parallel with a starting/stopping switch of an electric master control device of the motor; and a central processing unit is used as a core, and is connected with a timing unit, a power unit and an execution unit. A timing halting zero clearing unit is connected between the timing unit and the execution unit. The execution unit is connected with a normally open combined switch K. When the time of the timing unit reaches a set value, the central processing unit is requested to command the normally open combined switch K connected with the execution unit to directly delay the power supply of the motor of the electric water pump for a certain set time over the starting/stopping switch of the electric master control device of the motor. The device has the advantages of simple and rational structure, high intellectualization degree, unattended operation and good corrosion prevention effect on the main shaft of the motor of the electric water pump.
