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.
Spt 300 drilling rig can be towed and moved by tractors and other
tractors, so it is convenient and fast to move and has good
maneuverability. This drilling rig is equipped with 108 x 108 x
7500 mm Kelly and Φ 89x6000 mm sub - drill rod.
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.
SPJT300 Water Well Drilling Rig is installed on a trailer. This
drilling rig can work through rotary mud circulation or DTH
drilling technique.
SPjT300 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.
