Spray system with speed-based pressure controller and method of controlling same

摘要

Spray systems and control systems for use with spray systems are provided. A spray system generally includes a tank configured to hold a product, a conduit in fluid communication with the tank, a pump in fluid communication with the conduit, a flow controller, a plurality of electrically actuated nozzle assemblies in fluid communication with the conduit, and a pressure controller. The flow controller is configured to regulate a flow rate of product through the conduit based on a travel speed of the system. The plurality of nozzle assemblies is configured to dispense the product such that an upstream nozzle pressure is established within the conduit. The pressure controller is configured to control at least one operating parameter of at least one of the nozzle assemblies based at least in part on speed information indicative of the travel speed of the system to maintain a substantially constant upstream nozzle pressure.

1. A spray system configured to dispense a product as the system is moved at a travel speed, the system comprising:
a tank configured to hold a quantity of the product; a conduit in fluid communication with the tank for transporting the product; a pump in fluid communication with the conduit for generating a pressure in the conduit and a flow of the product through the conduit; a flow controller configured to regulate a flow rate of the product through the conduit based at least in part on the travel speed of the system; a plurality of electrically actuated nozzle assemblies in fluid communication with the conduit and configured to dispense the product such that an upstream nozzle pressure is established within the conduit; and a pressure controller configured to receive speed information indicative of the travel speed of the system and control at least one operating parameter of at least one of the plurality of nozzle assemblies based at least in part on the received speed information to maintain a substantially constant upstream nozzle pressure, wherein the pressure controller is configured to determine an anticipated change in the flow rate of the product through the system based on the speed information received by the pressure controller, and to control the at least one operating parameter of the at least one of the plurality of nozzle assemblies based on the anticipated change in the flow rate of the product.
