ABSTRACT:
A cotton picker moistening system is provided that includes a pump driven by an electric motor to deliver a pressurized flow of moistening fluid. The system also includes a detecting device for generating a sensed parameter signal representative of a characteristic of the fluid delivered by the pump, such as pressure or flow rate, and a signal generator for generating a desired parameter signal representative of the desired characteristic. A control circuit compares the sensed and desired parameter signals and generates a control signal derived from the sensed and desired parameter signals. The control signal is applied to the electric motor, the pump or a regulating device downstream of the pump to control the delivery of moistening fluid. A flush switch is provided to override the control circuit and cause predetermined flow of fluid to be delivered.
