Product Information of DFQ-150 Drilling Rig Machine
DFQ-150 drilling rig is a lightweight, high efficiency and multi-function drilling equipment,it can be
hauled by tractor or cars, easy to transport,convenient and quick. It adopts to two kinds of
working way---with mud pump or air compressor, strong applicability.
It is widely used for water well drilling,geothermal air-conditioning project and other boreholes,
especially applicable to mountain area and rock formation water engineering. Much higher efficient
than the traditional rotary drill rigs, creating the considerable economic benefit for users. Especially
solve the problems to drill very hard rocks that the traditional rotary drilling rig meet, our DFQ-150
is able to work efficiently under all kinds of geological conditions.
