Xuwei 280 Water Well Drilling Rig

Mechanical top drive series drilling rig is a kind of water well drilling equipment (national invention patent: ZL201510479602.4) independently researched and developed by the company, which integrates the functions of water drilling and pneumatic drilling. It adopts the 525 gearbox for vehicle use, which doubles the transmission efficiency compared with that of hydraulic transmission and reduces the energy consumption of the power by 35%, which is more efficient and energy-saving. It solves the problems of difficult drilling of air down hole hammer in soil layer and low construction efficiency of rotary drilling rig in hard rock layer, gravel and pebble layer.

The main features of the drilling rig:

1、The rotary speed of the drilling rig can reach 33-1120r/min rotary speed range, and the maximum torque output is 9800N.m.

2、The drilling rig adopts long travelling speed doubling mechanism, mechanical power head, and the power head travels 2400MM, which is used to improve the drilling efficiency and reduce the occurrence of plugging and burning accidents.

3、The drilling rig adopts double oil pumps for oil supply, single pump for drilling and double pumps for combined flow when lifting down the drill; less power loss and short auxiliary time.
