400m Crawler Pneumatic Rotary Water Well Drilling Rig Machine Prices For Sale/Drilling Rig
Introduction of crawler type Crawler Mounted Drill Rig
Water and air drilling rig is an efficient and multifunctional drilling equipment. It is mainly suitable for drilling water wells, agricultural irrigation wells, geothermal air conditioning holes and other wells, especially suitable for water intake projects in mountainous areas and rock formations. . The efficiency is ten times higher than that of traditional rotary drilling rigs, and the economic benefits created for users are extremely considerable. In particular, it solves the difficulty in drilling the soil layer with air DTH hammer, and the construction problem of the rotary drilling rig in the hard rock layer, gravel and pebble layer. It can work efficiently under various geological structures and realize the perfect combination of water drilling and air drilling.

Operation of well drilling machine when adding drill pipe
1. When the depth of one drill pipe needs to be connected after drilling, stop the propulsion first, then stop the rotation, and turn off the cooling water;
2. Stop the rotation and operate the fast forward and backward handle to the fast backward position to make the chuck quickly back in place; 3. The gyrator reverses, at the same time, it retreats the feed oil cylinder to rotate the water braid shaft away from the drill pipe;
4. Operate the clamping handle to make the gripper clamp the drill pipe and open the micro regulating flow valve (right rotation)
5. Connect the drill pipe to be added to the previous drill pipe, and the rotator moves forward while rotating. When the trapezoidal conical thread of the water braid shaft is in screw contact with the conical thread of the newly added drill pipe, immediately operate the gripper handle, loosen the gripper and complete the drill pipe addition.
