对液压支架用阀综合性能试验台液压系统的改进

Improvement of Hydraulic System of Valve Comprehensive Performance Test Bench for Hydraulic Support

目前对液压支架全动力阀试验台液压系统进行了改进,液压支架阀站液压系统未达到全循环相关标准,仅对液压支架阀的部分功能和性能与原试验台进行了对比检查,该液压系统结构简单,试验结果可靠。液压支架阀门产品是液压支架的主要控制部件,其工作效率直接影响液压支架的稳定性和安全性,因此,为了保证液压支架阀门的维修质量,液压支架阀门已成为液压支架大修的主要对象,必须提供可靠的检测和控制手段。

At present,the hydraulic system of the hydraulic support full power valve test-bed has been improved.The hydraulic system of the hydraulic support valve station does not meet the relevant standards of full cycle.Only some functions and performances of the hydraulic support valve are compared with the original test-bed.The hydraulic system has simple structure and reliable test results.Hydraulic support valve product is the main control component of hydraulic support,and its working efficiency directly affects the stability and safety of hydraulic support.Therefore,in order to ensure the maintenance quality of hydraulic support valve,hydraulic support valve has become the main object of hydraulic support overhaul,and reliable detection and control means must be provided.
