Submersible drilling rig in the history of the development trend of submersible drilling rig, the drill hole performance analysis increasingly important position in the Japanese mining machinery industry in China submersible drilling rig started earlier, the beginning of time, and the main hole drill cooperation projects in other countries, are some small companies are doing submersible drilling rig, and later, drill hole has a lot of special requirements, customer groups gradually increased, many large companies began drilling rigs research submersible drilling rig and the production, which is the development submersible drilling rig has played a good role in promoting. Deep hole drill rigs underground use, can hit 150 meters; anti-loaded impactor anchor rig, power, easy to use; tire type, small submersible drilling rig, low cost, high efficiency, ideal for small Mining Compact Track rigs, highway mountains, water conservancy and other special environments. Submersible drilling rig according to their working environment into surface drilling rigs and underground drilling rigs, surface drilling rigs: by crushing rock ore body of work, divided into rope percussive drill, drill hole, cone and rotary drill rig. Rope Rig impact due to low efficiency, has gradually been replaced by other rig. Underground Drill: drilling diameter less than 150 mm of underground boreholes, in addition to the application can also be applied outside drills 80 to 150 mm of the small-diameter hole drilling. Replace Drill Accessories throttle 1, replace the valve plate and seat: Remove the valve chamber pressure, remove the valve cover bolt rig, the valve plate and valve cover over some taken together. Remove slotted round nuts, switch pin, socket screws, front stopper cap rotary drilling rig, you can replace the cylindrical valve plate, replacing the seat. Clean the valve chamber, should be extra careful sealing surface. Replaced with a new valve plate, valve seats, should cover some of the gap at the boss before the valve plate and valve filled with sealant and fill the inside cover of calcium-based tanker rig smooth so smooth bearings. 2. Replace the lip seal packing: Remove the valve cavity pressure to perform first, then open the cover, round nuts, hand wheels, bearings gland, bearings, packing gland, and then replace the lip seal packing. 3, replace bearings: open guard, round nuts, hand wheels, bearings gland, then can put on bearings. To replace the lower bearing, to be relieved stem nut, bearing gap bearing cap adjustment, the adjustment is completed, the rolling movement of the hand wheel should be sensitive, without jamming.
