Ámbito de aplicación


SR400 pneumatic hydraulic water well drilling rig 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 mud rotary drill rigs, creating the considerable economic benefit for users. Especially solve problems to drill hard rocks that the traditional rotary drilling rig meet and it should work with air compressor. When drill soft underground formation, it is OK to use mud rotary drilling, and there is mud drilling swivel system.
