Product Description:Reverse circulation dust fixed pointSampling device according to standardGB/T23250 "coal seam gas content underground direct measurement method"and 《Rules for Prevention and Control of Coal and Gas Outburst》The specified sampling requirements, the use of advanced multi-stage ejection technology, to achieve with the drilling, non-withdrawal drill pipe fixed-point sampling, can be in.20 minutes.Inner realization coal seam100Fast fixed-point sampling at any point within a range of m or greater. It is a complete set of equipment with advanced concept and high sampling success rate in China.Our company has applied for patent technology, this process is mainly used for dust monitoring in the process of sampling measurement, coal powder gas content and fixed-point dust sampling of pre-drilling and post-reverse circulation sampling..
Instructions for use:In the normal drilling process, it is preferred to use ordinary water braid for drilling. At this time, the inner wall and outer wall channels of the drill pipe are ventilated at the same time. In the drilling process, it can effectively prevent excess cinder from entering the inner wall of the drill pipe through the middle channel. When drilling to the designated position, it is replaced with a reverse circulation dust sampling water tail device, and the outer wall is continuously supplied with air. The air is discharged through three ventilation channels around the double-wall around the drill bit, in the confined space, return the pulverized coal to the inner wall of the double-walled drill pipe through the ventilation hole in the middle of the drill bit. Through continuous air supply, the cinder will continue to flow back until it flows into the dust box through the water braid. At this time, the fixed-point sampling is completed.
