Product Description
Product Introduction:
1.The clutch cylinder of a rotary drilling rig controls the clutch operation, ensuring smooth rotation and feed of the drill bit. Controlled by a hydraulic system, it enables rapid engagement and disengagement of the drill bit to adjust rotation speed and feed force.
2.The pressurizing cylinder of a rotary drilling rig applies pressure to the power head, transmitting it through the drill rod to the drill bit for cutting, crushing, or grinding.
3.The stabilizer cylinder of a rotary drilling rig adjusts the extension/retraction of the stabilizer arm to enhance rig stability and guidance during drilling. Its flexibility and adjustment capabilities allow the rig to adapt to varying working conditions, improving efficiency and borehole quality.
4.The rod coupling cylinder supports the mast and ensures stability and safety during rod lifting and lowering.
5.Customizable designs are available to meet client needs, offering integrated solutions.
