DN内注式单体液压支柱产品介绍

DN型内注式单体液压支柱为恒阻式支柱,与金属铰接顶梁配合适用于煤矿一般机械化采煤工作面顶板的支护,也可用于综合机械化采煤工作面端头支护或临时支护。

DN内注式单体液压支柱适用于煤矿回采工作面的顶板支护和端头顶板支护,由于其承载能力大、抗偏载能力强、工作行程大、使用范围广,因而其可应用于薄煤层、中厚煤层及较厚煤层工作面zy18。

DN内注式单体液压支柱适用范围

1、煤层倾角:煤层倾角小于20°的缓倾斜回采工作面,采取一定安全措施后亦可用于倾角为25°~35° 的回采工作面。

2、高度:不大于支柱的zui大高度,即DN18型支柱zui大支撑高度为1.8m,支撑高度变化范围一般为1.31.8mDN22型支柱zui大支撑高度为2.2m,支撑高度变化范围一般为1.62.2m等等。

3、支柱在承压过程中不应以支柱的中部作为推溜千斤顶的支点推溜;

4、在炮采工作面使用时,应采取措施防止支柱的活柱表面被崩坏。

DN内注式单体液压支柱工作原理

DN内注式单体液压支柱工作液为5号液压油, 回柱时油缸中液压油流回活柱内腔形成封闭式循环;不需要泵站和管路系统, 配套设备少, 成本低; 在没有电源和泵站的地方照样使用, 灵活性大、管理方便、简单; 由于工作液是封闭式循环, 支柱回柱时液压油流回活柱内腔, 实现支柱本身液压油的闭路循环, 液压油消耗很少; 支柱液压系统为闭式系统, 液压油不外溢, 不污染环境, 有利于环保, 并对工作面生产影响小, 较好地保持了工作面环境, 劳动条件较好; 支柱的阀全部装在支柱内腔, 受外界污染的可能性小, 可靠性高。
