Patent Description:
A pump is a machine that conveys fluid or pressurizes the fluid. Generally, a drive motor is arranged in the pump, and the drive motor is provided with a control box configured to control operation of the drive motor. Generally, the control box also needs to be provided with an outgoing line adapter interface configured to connect a signal line or a power line extracted from a client. The client is configured to transmit a control signal or supply power to the control box to control operation of the drive motor.
