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.
Technical advantages of water well drilling rig platform
High construction efficiency: full hydraulic top drive, meeting the construction of L-shaped well and high drilling efficiency; Intellectualization: automatic loading and unloading of drill pipe to reduce manual labor intensity; High mobility: all terrain off-road chassis, suitable for complex road conditions; Multi technology drilling: air DTH hammer, mud drilling and other construction technologies.
1. Power system to provide energy for the whole drilling rig;
2. Working system, equipment working according to process requirements;
3. Transmission system is the equipment that transmits, transports and distributes energy for the work unit;
4. Control system, control all systems and equipment, and accurately coordinate work according to process requirements;
5. Auxiliary system, equipment of auxiliary main system.
