主动式瓦斯压力测定仪
主动式瓦斯压力测定仪产品介绍
瓦斯压力是瓦斯涌出和突出的动力,也是决定煤层瓦斯含量的一个主要素,准确测定瓦斯压力对矿井有效而合理地制定防止瓦斯措施,预测预报煤与瓦斯突出的危险性,具有重要的意义。前国内煤矿大都采取粘土、水泥砂浆等固体物封孔测压,这种测定瓦斯压力的方法在封孔段岩层坚硬致密的条件下一有效,是当封孔段岩层为松软砂岩或钻孔周围存在微裂隙时,封孔的固体物不能严密封闭钻孔周边的裂隙,因而易漏气,封孔效果不理想,测出的瓦斯压力值低于煤层真实的瓦斯压力。这样会导致错误的技术判断,造成事故隐患。
主动式瓦斯压力测定仪工作原理
主动式瓦斯压力测定仪采用一种胶囊—压力粘液封孔测定煤层瓦斯压力技术,利用粘液能够在压力作下渗入钻孔周边裂隙的原理,能够有效解决针对松软岩层的封孔测压中瓦斯泄漏的问题,从而使测出的瓦斯压力值等煤层真实的瓦斯压力。
主动式瓦斯压力测定仪主要性能
采用手动乳化液泵将乳化液压入胶囊之间,使胶囊膨胀,加强密封效果。适用于作液压能源,提供所需的压力。采用水、乳化液和液压油作介质,对于各种压力容器、管道阀门、矿用防爆件等进行压力试验。
采用手压作动力,设计合理,操作省力。增设蓄能器储能,出口单向阀加高压截止阀,起到双重保压作用。结构紧凑,重量轻,维修方便。
