What Causes The Weak Rotation of A Rotary Drilling Rig And What Are The Solutions

In engineering construction, if the rotary drilling rig experiences weak rotation, it will affect the construction efficiency. The following is an analysis of the common causes and solutions to this problem for everyone.

1. Hydraulic system failure: Insufficient or contaminated hydraulic oil can lead to insufficient system pressure. It is necessary to check the oil level and replace it with clean hydraulic oil. If the hydraulic pump or motor is worn and leaking, its components should be repaired or replaced.

2. Problems with slewing bearings: If the gears of the slewing bearing are worn or poorly lubricated, grease can be added. In severe cases, the supporting device needs to be replaced.

3. Insufficient power: The engine power drops. Check the fuel, intake system and engine condition, and carry out timely maintenance and repair.

4. Control valve jamming: If the valve core of a multi-way directional control valve is stuck, the hydraulic oil will not flow smoothly. Disassemble and clean the valve core or replace the control valve.

5. Mechanical component jamming: If the transmission components of the rotary mechanism, such as gears and pins, get stuck, it is necessary to inspect and remove foreign objects, and lubricate the moving parts.

6. Abnormal electrical control system: Sensor or line failure causes poor signal transmission. Inspect the circuit and repair or replace the damaged components.

In conclusion, if a rotary drilling rig has weak rotation, it is necessary to investigate from multiple aspects such as hydraulics, mechanics, power and electricity. After identifying the cause, targeted solutions should be taken to ensure the normal operation of the equipment and improve construction efficiency.
