VARIABLE ORIFICE SPRAY HEAD OF LIQUID DELIVERY SYSTEM AND CALIBRATION SYSTEM

摘要

A liquid delivery system includes an engine and a hydraulic circuit, which includes a hydraulic pump driven by the engine and a hydraulic motor driven by the hydraulic pump. A liquid pump is driven by the hydraulic motor and is configured to provide pressurized liquid along a liquid conduit. A variable orifice spray head is configured to receive the pressurized liquid from the liquid conduit and deliver the pressurized liquid through an opening of the variable orifice spray head. An actuation mechanism is configured to change a size of the opening of the variable orifice spray head responsive to command signals. An electronic control module has a spray head calibration algorithm executable thereon that identifies a correlation, which is stored in memory, between a variable orifice spray head command signal and a target variable orifice spray head opening size based on a hydraulic pressure along the hydraulic circuit.

1. A liquid delivery system, comprising:
an engine; a hydraulic circuit including a hydraulic pump driven by the engine and a hydraulic motor driven by the hydraulic pump; a liquid pump driven by the hydraulic motor and configured to provide pressurized liquid along a liquid conduit; a variable orifice spray head configured to receive the pressurized liquid from the liquid conduit and deliver the pressurized liquid through an opening of the variable orifice spray head; an actuation mechanism configured to change a size of the opening of the variable orifice spray head responsive to command signals; and an electronic control module having a spray head calibration algorithm executable thereon, wherein the spray head calibration algorithm identifies a correlation between a variable orifice spray head command signal and a target variable orifice spray head opening size based at least in part on a hydraulic pressure along the hydraulic circuit, and stores the correlation in a memory.
