crawler chassis rotary water drilling rig
SPJ300 Water Well Drilling Rig is installed on a crawler. This crawler chassis drilling rig can work through rotary mud circulation or DTH drilling technique. SPT300 trailer chassis water well drilling rig is suitable for clay, sand, graveland pebble, and rock stratum. We add special device to add & reduce pressure during drilling which can enhance efficiency a lot. High hydraulic leg and hydraulic tower are chosen to save labor and keep safety during working.
The common rotary drilling rig, namely the rotary drilling rig with positive circulation mud flushing, consists of a tower, a winch, a rotary table, a drilling tool, a mud pump, a faucet, a motor, etc. During operation, the power machine drives the rotary table through the transmission device, and the driving drill rod drives the drill bit to rotate the broken rock layer at a rotation speed of 30 to 90 revolutions per minute. The mud is pumped and pressurized by the mud pump and then is pressed into the hollow drill rod through the faucet above the drill rod, flows downward into the drill bit, and is ejected from the nozzle to cool and lubricate the drill bit; Debris from the bottom of the well is taken out of the wellhead through an annular channel outside the drill pipe. after settling in the settling tank, mud flows back to the mud tank for recycling. Some rotary drilling rigs are equipped with mud pumps and air compressors at the same time.
◎ when drilling, the drilling rig uses an independent diesel engine as power, and uses mechanical transmission to make the mechanical winch and rotary table work at the same time;
◎ the drilling rig is equipped with four hydraulic support legs, which can move at the same time as well as independently, facilitating quick leveling of the drilling rig. Moreover, the two rear legs can extend horizontally, thus improving the stability of the whole drilling rig. Using hydraulic cylinders to lift the tower is convenient, reliable and simple to use, which can meet the construction requirements of different working conditions to the greatest extent.
◎ the main parts of the drilling rig, such as winch, turntable, gearbox, tower and chassis, are produced by our factory independently, with stable and reliable performance.
◎ the drilling rig is suitable for drilling high-rise buildings, bridges, geological mines, ports, dam foundations, water well construction, complicated ground source heat pump, etc.
◎ the drilling rig is simple to operate, has strong usability, convenient maintenance, less investment and quick effect, and is the best product for users.
