JK-DR series(180, 200, 300, 350, 400, 500, 600, 800 and other models of rotary full hydraulic controlled water well drilling rigs are multifunctional, it can be used with air compressor, mud pump, even we can just use the dry hydraulic drilling method. The portable drilling rigs are not only designed for water, they can also be used in all conditions based on pore-forming purpose.This series of water well drilling machine has the characteristics of standardized configuration, compact and reasonable structure, fast drilling speed, economical and durable, low failure rate, etc. It has been recognized by the market once it is launched, and has been widely used in mining engineering construction, civil drilling, geothermal drilling and other fields. They are widely used in industrial and agriculture water project, testing well and other exploration borehole. In particular, drilling hole for geothermal heating, it can also meet the engineering basis for reinforcement, loose gravel drilling rock formation connected with a variety of engineering. Our drilling rigs are more efficiency and with low failure rate, more economic and durable, and with a high comprehensive cost performance.
