Pneumatic bolt rig in use should pay attention to the problem of pneumatic bolt rig is mainly used in the coal industry, with a light weight, simple operation, easy maintenance, etc., then the rig at the time of use What precautions, let Drilling Rig Manufacturers tell you. 1, bolt rig operating torque and thrust should match, at the construction site, the air pressure DTH drilling rig in the drilling process, there will be drilling rigs blocking phenomenon will reduce the drilling efficiency. Because the first thing to stop blocking drill, reduced the drill pipe, the pressure submersible drilling rig, to find a positive, re-drilling, drill bit often live rock paste, Shanghai in air pressure DTH drill, drill pipe can not easily be removed, very time-consuming . 2, to provide sufficient pressure Roofbolter air volume, domestic pneumatic bolt rig normal control pressure of 0.4 a 0.63MP, air pressure pipe diameter of not less than Φ25. Only to meet the above conditions in order to ensure that the bolt rig operating at rated conditions. 3, water pressure should be matched with the compressive strength of the water pipe, Shandong pressure submersible drilling rig in the use of the site, the situation often have bolt rig itself, the water pipe burst. Once you Burst, the device is not working, and to the production of unnecessary losses. When this occurs, that is, through the water pressure is higher than the pressure caused by the water pipe. Inspection hole drill hole drill work before as a large ore excavation machinery and equipment, before the usual start of work in general have trouble checking maintenance machinery and equipment, accident prevention failure. During normal use, the work before the job is how to prepare it? The first point is the maintenance personnel must carefully check whether gas water pipe connections are secure, there is no leak leaking phenomenon, prevent entry of air drills phenomenon lies in the drilling process, to avoid damage to the drill bit. It has filled the second point is to check the oiler oil, which is the basic common sense to check power system must be checked. The third point is to check the various parts of screws, nuts, joints, etc. is already tightened the top of the column is indeed very strong. Do the work of three of the above checks, to start submersible drilling rig began operations.
