Development Of A Test Bench For Water Hydraulic Valve Orifice

Water hydraulic technology has a very broad application prospects inengineering machinery, marine development, new energy and other fields，because ofits green, safe, efficient, low cost, etc. Pressure control valve is an important part ofthe water hydraulic technology.Promote the use of large-scale water hydraulic drivetechnology must be developed a high-performance water-hydraulic control valve as aprecondition. The research of characteristics of a hydraulic pressure control valveorifice must be put into the first place. In this paper, in order to improve the hydrauliccontrol valve design methods and theories as the ultimate goal, according to thespecific requirements of the project, designed and developed a set of functionalcharacteristics of hydraulic valve port test platform. The main work is as follows:According hydraulic valve port on the hydraulic characteristics of the testplatform for the performance requirements of the power source, This article refers todesign methods and principles of hydraulic power systems with full account of thespecial requirements of water as the working medium. With a detailed structuraldesign and analysis to the hydraulic power source, select and configure its drivesystem and completed the design and assembly of seawater hydraulic power system.As the topic of water pressure valve port features high-pressure test apparatus and thesubsequent testing of the device.On the basis of the full study of existing hydraulic and pressure relief valve,according to the existing level of design and manufacturing experience, the paperdeveloped a secondary throttle pressure relief valve, as the experimental system loadand pressure seawater hydraulic power system protection components. Pressure reliefvalve and the throttle opening two forms of cavitation characteristics were calculatedand analyzed.Content for hydraulic valve port performance test requirements, developed a hydraulic valve port characteristics mainly for test equipment and lift hydraulicdamping valve port openings, including mechanical systems, hydraulic systems andtest systems. The test device can achieve hydraulic valve port test by replacing themounting dimensions standardized plug and seat.Based on virtual instrument technology and Labwindows/CVI softwareplatform, a hydraulic valve port characteristic test signal test and data acquisitionsystems is developed. Including all sensors and hydraulic valve port select the desiredcharacteristic test, selection, testing software programming signal data acquisitioncard and so on.In this paper, a preliminary test developed hydraulic valve port characteristicstest bench and test indicated that the hydraulic valve port characteristic test systembasically meet the design requirements, can provide an effective experimental basisfor the future development of hydraulic control valves.
