钢丝绳牵引胶带输送机是矿业主要运输机械之一,由于其 机构庞大,停车惯性大,不及时制动会使停机缓慢,造成不安全隐患（它的制动是靠盘闸）。 鸡西煤炭公司正阳矿在使用此输送机的过程中,发现其液压泵站系统制动油缸松闸不可靠,出现松闸时又瞬时制动的抖动情况。检修发现液压系统（见图1）单向阀6已失效,深入检查才能知道是蓄能器充气不足所致。这直接关系到液压泵工作性能,影响了制动系统的可靠性。
Rope towing belt conveyor is one of the main transportation machinery in the mining industry. Due to its large structure and large parking inertia, failure to brake in time can cause slow stoppage and cause unsafe hidden danger. Jixi Coal Company Zhengyang mine in the process of using this conveyor, found that the brake system of the hydraulic pump station system brake unreliable, there is instantaneous braking brake jitter situation. Repair found hydraulic system (see Figure 1) check valve 6 has failed, in-depth inspection to know is due to insufficient accumulator. This is directly related to the hydraulic pump performance, affecting the reliability of the braking system.
