low consumption of energy and a low temperature of hydraulic system oil strong applicability and a large serviceable range.
CXY-4 is a new model core rig drilling with high speed diamond-bit designed and manufactured by Chemshine . basing on the exploration technique development in China, considering the geological condition of the country. The CXY-4 core rig has 8 speed grades. Its highest speed can be 1588rpm; and it can also work at 101rpm, a very low speed. So the rig has a strong applicability and a large serviceable range. Besides mainly applied to earth surface and gallery exploration of solid deposits by using diamond or tungsten carbide bits, it could be applied to geological exploration and prospection, and it also could be used for superficial petroleum and natural gas exploration and for groundwater finding drilling. It could be applied to the projects drilling of dam grouting and sap ventilation etc.
Adapted on core drilling with tungalloy-carbid-tipped and diamond oil as well as engineering geology exploration, hydrology well drilling and basic pile engineering Fed with double cylinders that travel much longer The adopted technology can be adapted on many models, especially on large diameter drill pipe drilling that extracts the core with wire line (up part), thus it is more effective for improving drilling efficiency and decreasing the rate of trouble Hydraulic spider disk with a hydraulic lock is supplied oil in two opposite directions Strong and steady clamping force The drill is aligned a water brake Steady and secure in deep hole drilling Adopts a double-gear pump to supply oil Operates with single or double gears, so there is a low consumption of energy and a low temperature of hydraulic system oil, and the drilling is steady Hand reeling oil pump may be used to hoist the drilling tools in hole when the power engine can not operate Tight structure and reasonable layout Low centroids a long traveling distance (up to 460 mm), a reliable fixation and a good stability in high speed drilling Easy to master the hole condition with a long life anti-vibration instrument.
