HW-220L Mud/Air Drilling Rig
HW-220L series drilling rig is a kind of high efficient and multiple functions drilling equipment, It is mainly suitable for drilling wells, agricultural irrigation wells, geothermal air conditioning holes and other well holes, It is especially suitable for water intake projects in mountainous and rocky strata. The efficiency is more than ten times higher than that of the traditional rotary drilling rig, and the economic benefit created for the user is very considerable. Especially to solve the soil air DTH drilling difficulties, the construction problems of rotary drill hard rock layer, gravel layer, able to work effectively in a variety of geological structure, to achieve the perfect combination of water and pneumatic drill.
