ASC series mainly serves the mud purification treatment in trenchless construction, The comprehensive treatment of cyclone and shale shaker is used to separate the mud particles, reduce the sand content of the mud, so that the mud can be recycled. It has the advantages of saving the cost of mud making, meeting the requirements of construction grouting, and reducing environmental pollution.AsC series desander can be matched with the construction equipment includes horizontal directional drilling rig, pipe jacking machine, etc.
ASC series:ASC60、ASC120、ASC200A、ASC200B、ASC200C
The rig is powered by CUMMINS high efficiency turbocharged engine, which is economical, practical and easy to maintain. Independent research and development of large torque, strong impact power head, stable and reliable work, wide range of formation adaptation. Independently developed crawler chassis, with large traction, variety road adaptability, smooth and reliable crawler Motor +gear box chain structure is adopted for feed and pull back, with wide speed range. The hydraulic system adopts load sensing technology, the system has higher efficiency. A wide range of mast, multi-Angle changes, can be adapted to a variety of different working conditions. Swing operation panel let operators to operate the drilling rig with more convenience and easiness.
The single roler bit is composed of a single cone and a lug matched by a bearing.According to different strata and construction requirements, different cutting struclures can be selected; wear resistant carbide are welded and cemented carbide inserts are inserted on the back of the lug.
Rotary drilling rig drives the shaft to rotate and exert positive pressure so that the rotary dril- ing bit can impact, roll and shear the rock. Crush the rock to form a crushing ring zone.Then break the middle pillar by the swing of the shaft and take the broken pillar out to form a hole.
