Masters ZDY750 mine tunnel drilling quality win the trust of the people I felt a little out car, a job feel less a tool, one should pick up the phone feeling for everyone to call. There is a demand to buy, please call: ①⑤ zero ⑨②⑥⑥ ②⑨②② structural features ?? ZDY-750 drilling rig mainly by the pumping station, power head, rack, column frame, console and drilling tools and other components. Rig pumping stations and power head connected by a high-pressure pipe of different diameters, all using quick connect fittings head installation withdrawal unloading easy handling. Pumping oil pump is driven by a rotation-proof motor, converting electrical energy into rotational advancing oil passage and the oil passage of hydraulic energy (hydraulic fluid), and then by manipulating valve stage pressure oil supplied to the hydraulic actuator, in order to achieve rig various functions. Scope ?? ZDY750 Mine hydraulic tunnel drilling rig is mainly used for coal mine gas extraction (row) to put hole, grouting fire hole, coal water holes, anti-conflict relief hole, holes, and other engineering geological exploration holes. Suitable for all kinds of coal f≤10 consistent coefficient of rock, rock. Within the azimuth and inclination range any drilling rig can be specified in the basic parameters of the table.
