Structure and principle of power head positive circulation drilling rig

Structure and principle of power head drilling rig

1, DZJ-1500 power head positive cycle drilling rig is composed of construction site, rig, motor, reducer, main winch, auxiliary winch, hydraulic oil pump, oil cylinder, mud pump, power distribution, drill pipe and drill bit.

2, the motor is a Y series ordinary motor

3. The speed reducer has three speeds of four-axis three-stage spur gear, deceleration, and cm, 31, 66, and 93 revolutions, and the speed change mode is gear speed.

4. The main shaft adopts Y type rubber oil seal, and the rest are skeleton oil seals.

working principle

1. The rig's walking and steering are all composed of hydraulic system. It is controlled by the operating handle to make it complete the walking forward, backward walking and steering U-turn.

2. The motor transmits the power to the output shaft through the reducer, which drives the drill rod and drill bit to cut. The mud is pumped through the mud pump to the center to discharge the cut slag from the well hole into the slurry tank. It enters the circulation through the mud pump.
