Due to different technical requirements, the rotary excavator pile driver can no longer meet the customer's requirements. The customer needs to transform the rotary excavator pile driver into a rotary jet pile driver. In addition to the renovation of the mechanical part, the electrical part also needs to be renovated simultaneously.
Firstly, dismantle the original cam controller and electrical control, add a frequency conversion control cabinet, and remove the brush part of the wound motor. Short circuit the motor rotor winding.
Control principle: When the winch motor reaches 10Hz, the brake motor opens, and when it drops below 10Hz, the brake is applied. The winch motor is controlled to operate through external terminals and uses multi-stage speed control to regulate the speed.
