The hydraulic system is the muscle of the crawler mounted drill rig, and its control is a vital part of the overall control system. Hydraulic valves are used to direct the flow of hydraulic fluid to different actuators, such as cylinders and motors.
[pdf] A flow line, used on a drilling rig, is a large diameter pipe (typically a section of casing) that is connected to the bell nipple (under the drill floor) and extends to the possum belly (on the mud tanks) and acts as a return line (for the drilling fluid as it comes out of the hole), to the mud. .
The is used to slow the flow of returning before it hits the . This enables the shale shaker to clean the. .
A stinger line is similar to a flow line, but unlike a flow line is not used to maintain circulation. The stinger line is attached to the .
Another common add on is the sample box. This is a heavy duty rubber hose that is inserted at the end of the flow line and at the other end emplaced into the sample box itself. The.
[pdf] The KT5C Integrated down the hole drill rig for open use is an advanced drilling device integrating the down the hole drilling system and screw air compressor system, characterized by compact structure, excellent integrity and mobility.
