SYSTEM FOR REGULATION AND CONTROL OF WATER PRESSURE AND FLOW RATE IN A HIGH PRESSURE WATER APPLICATION

摘要

A water bypass valve and system for regulation and control of water pressure and water flow rate in high pressure water applications having a water pressure safety relief valve. An operator may select a desired water pressure setting in an operator interface. The water system may be controlled by a computer processor that receives pressure data from a transducer in a high pressure discharge line and a speed sensor at a water pump drive shaft. The water bypass valve, controlled by the computer processor, may regulate water flowing back to the water supply tank, allowing the safety relief valve to remain closed over a wide range of water pump operating speeds.
