The Development Of Comprehensive Performance Hydraulic Test-bed For Steering Gear Pump

With the rapid development of equipment manufacturing today,hydraulic products have been widely used in various fields.As hydraulic components are power and control components in equipment,their performance is an important guarantee for the stable and reliable operation of hydraulic system and main engine equipment.This topic research the hydraulic steering gear pump to provide all kinds of engineering vehicle hydraulic power steering dynamics,the influence of vehicle steering performance and stability,related to the life safety of the driver,so the performance of the hydraulic steering gear pump is very important,people to test the hydraulic steering gear pump performance test system put forward higher requirements.This topic is derived from the enterprise internal cooperation projects hydraulic steering gear pump comprehensive performance test bed.In this article,through contrast national and industry standards,and analyzes the test project,summarizes the project requirements,to design the hydraulic principle.Design concept: the participants hydraulic steering gear pump as the power source into the test loop,using plug-in relief valve,proportional relief valve as a load,simulating the actual working condition of the subjects pump,in order to achieve the purpose of testing its real performance.The measurement and control system adopts the technology of frequency conversion,automatic control and sensor,and sets up the measurement and control scheme of PLC as the control center,using the computer control machine and the touch screen display.This test bench has realized the computer automatic control and testing project implements single automatic and manual test and automatic test pilot project in a row,computer data collection and processing software using the Windows platform,with data collection and processing,printing,graphic drawing and other functions.In the face of problems in manufacturing and debugging,such as flow detection,oil pollution and electromagnetic interference,a careful analysis is carried out,and corresponding solutions are proposed.The hydraulic steering gear pump comprehensive performance test bed,in actual use process,meet the design requirements,meet the needs of users.
