液压支架存在的主要故障及预防对策探究

Main Problems Existing in Hydraulic Supports and Countermeasures for Prevention

在煤炭工业中,液压支架作为煤矿企业综采工作面作业过程中的一种大型液压动力支护装置,它是煤矿企业进行高效生产和安全生产的核心必备设备。随着液压支架的在用基数递增和高频次化的生产需求使用,其设计缺陷、使用故障等不安全因素引发的生产事故增多。根据液压支架常见故障及其产生原因,提出相应的防御对策或维修措施,以期确保煤矿企业的安全生产和煤炭产量,进而提高企业的经济效益。

In the coal industry, hydraulic support is a large hydraulic power support device in the process of fully mechanized coal mining face, which is the core equipment for the high productivity and safety production of coal enterprises. With the increasing demand of hydraulic support and increasing demand of high-frequency and secondary production, production accidents caused by design safety and failure factors are increasing. According to the common faults and causes of hydraulic support, the corresponding defensive countermeasures or maintenance measures are put forward, so as to ensure the safety production and coal output of coal enterprises, and then improve the economic benefits of enterprises.
