我厂有多种大型、复杂的液压设备,其维护工作是一个重要的问题。如本车间泵站油箱总容量超过4万升,数以百计的执行回路遍布于钢卷开卷机系统、飞剪的剪切系统、垛板系统及包装线。任何一个部位的故障随时都可能造成整个作业线的停机。为此,我们对液压故障的现状作出分析以求有效的对策。首先抽取半年液压故障处理记录分析,知系统的漏油故障最频繁,占整个故障次数的55.17％。在各种部位的泄漏中,以管接头和管道的泄漏最为严重,达到总泄漏故障的86％。为了有针对性地加以防范,我们又对在现场处理故障中所见到的管接头泄漏的各种现象、特征、形式作了归纳比较(见表)。
I plant a variety of large, complex hydraulic equipment, the maintenance is an important issue. If the workshop pumping station total capacity of more than 40,000 liters of fuel tanks, hundreds of the implementation of the circuit throughout the coil uncoiler system, flying shear system, plywood systems and packaging lines. Any part of the fault at any time may result in the shutdown of the entire line. To this end, we analyze the status of hydraulic faults in order to find effective solutions. First of all six months to extract hydraulic troubleshooting records, the system known the most frequent oil spills, accounting for 55.17% of the total number of failures. In all parts of the leakage, the joints and pipe leakage is the most serious, reaching 86% of the total leakage failure. In order to prevent it in a targeted manner, we also summarize the various phenomena, characteristics and forms of the joint leakage seen in the field troubleshooting (see table).
