取料小车升降缸液压控制阀组优化分析

Optimization Analysis of Hydraulic Control Valve Group for Reclaiming Car Lifting Cylinder

液压系统的控制部分(阀组)控制着执行部分油缸或马达、摆动油缸的速度、位置。若对速度、位置精度要求高的,设计人员对控制阀的选型配置要求是非常严格的,但在现实的实际工况环境下,有些精度高的控制阀又不能发挥高精度的功能作用,且还导致成本高和故障率高。该文就一种取料小车升降缸液压控制阀组的优化进行了分析以及实施。

The control part of the hydraulic system(valve group) controls the speed and position of the executing part of the cylinder or motor and the swing cylinder. If the high requirements for speed and position accuracy, designers of the control valve selection and configuration requirements are very strict, but in the reality of the actual working conditions, some control valves with high precision can not play a high-precision function, and also lead to high cost and high failure rate. This paper analyzes and implements the optimization of a hydraulic control valve set for the lifting cylinder of the trolley.
