Hebei roof separation instrument, Warner Electric (certified), roof separation provided by Warner Mechanical and Electrical Equipment Co., Ltd. Tai'an City. Warner Tai'an City Electrical Equipment Co. (www.tahnjd.com) is specialized in the "roof dynamic instrument, mine intrinsically safe pressure detector, under reduced pressure hydraulic supports self-recording instrument" of enterprises, companies adhering to the "honesty, hard service "concept, to provide you with the highest quality products and services. Welcome to inquire! Contact: Mr. How safe production of roof separation instrument should install roof separation lane wide in the middle of the roadway separation indicator should be installed at the intersection of the center at the intersection. Before installing the first instrument to check good, the wire is securely connected at both ends, the inner and outer tube is installed correctly. Use anchor or extension Qianzai installation, after installation cleaned up the scene. The lower part of the measuring point should be at the same height as the upper end of the bolt, the upper measuring point should be set in the rock bolt above the stable 300-500mm. No steady rock roof separation offer, generally not less than 1.5 times the span of the roadway. Roof separation a brief observation Responsible: Team Group Technician for the construction of the roadway roof separation within the monitoring and recording of Hebei roof separation instrument, complete roof separation instrument management license plates, and is responsible for monitoring data summary, filing, the other attendant team must always observe the stem in order to detect anomalies in Tianjin roof separation instrument, in time, to ensure safety. 2, the frequency of monitoring: a newly installed roof separation must be observed and recorded at least seven consecutive days, according to changes in the actual observation instrument separation (separation rapidly changing reading instrument) in special areas, requiring technicians daily detect and record the amount of movement in the roof roof separation instrument safe zone, requiring weekly testing and records. 3. Monitoring Methods: roof separation observation instrument of deep and shallow scale reading minus the initial value equal to move; when within range of roof bolting sinking roof separation instrument, roof separation of deep and shallow two basis points The scale has changed within the range of Cable Supporting roof subsidence within the range of roof bolting is not moving, deep roof separation point scale changes only if the anchor, anchor roof support within range while When the sink, roof separation deep, shallow point on the scale has changed, and the amount of change in the deep point scale that is the sum of the amount of roof subsidence.
