单体液压支柱更好的保证了施工人员的安全问题

发布日期:2018-08-14 作者: 点击:

黑龙江单体液压支柱入井前是要进行压力测试的,那么这个测试是怎样进行的呢,下面请跟着小编来学习看一下吧,看看单体液压支柱入井前的测试是怎样的。一般做压力试验的办法就是将油缸连接到液压源上,也就是泵站给油缸一定的压力,要超过正常使用压力进行压力试验,连接部位和系统内不能有泄漏,根据压力的变化来确定是否能保证使用,再一个办法就是把油缸给上一定的压力后给支柱的顶部加载荷根据载荷的变化来确定油缸的质量。单体液压支柱设备的局部划伤及变形是单体液压支柱常出现的问题,尤其是活塞口变形泄露、井下液压支柱腐蚀等问题。


单体液压支柱由于设备拆卸较为困难,单体液压支柱出现上述问题后传统方法多难以现场解决,以更换新备件为主,但更换周期长且费用较高。当代针对单体液压支柱最新维修方法以高分子复合材料为主,其中应用最为成熟的是美嘉华技术体系。其具有优异的附着力和良好的抗压能力,不但能够满足上述工况下的生产使用要求,且操作工艺简单易行,既无热影响,涂层厚度又不受限制。同时涂层本身具有的优越的耐油耐腐蚀性能及自润滑功能,确保了修复后的耐磨性能,保证了企业的正常生产,避免了设备部件的损坏加剧。现在的一切都要从环保出发,那么你知道单体液压支柱是不是环保呢,单体液压支柱新型具有结构简单,单体液压支柱使用方便,便于更换的优点,可大大延长液压单体支柱的使用寿命。 金属顶梁可与各种类型金属单体液压支柱配合组成金属支架,供煤矿在水平及缓倾斜回采工作面支护的一种高强度顶梁,由于这种顶梁能悬臂支护工作面、煤壁面前边的运输机道上面的顶板,是煤壁与单体液压支柱间有较大的支护空间。
