Rotary drilling rig safety education content Analysis of common faults of rotary drilling rigs.Turkey Excavator sprocket

Rotary drilling rigs often have no action, high water temperature, no power, weakness, boredom, single pump walking, stuck machine, hydraulic pump trembling, lack of power, no action, slow action, large hydraulic pump noise, powerlessness, suffocation, suffocation The car, the oil temperature is high, the arm is dropped, the card is issued and other faults.Turkey Excavator sprocket

The fuel system can be divided into a high-pressure part and a low-pressure part: the high-pressure water pump is mainly the pump nozzle part, and the low-pressure part includes the fuel pump, fuel filter, oil-water separator, etc. If there is air, impurities, insufficient pressure in the system, pressure relief in the system, blockage, insufficient injection volume of the pump nozzle, etc., the above faults will be caused.Turkey Excavator sprocket

Common fault analysis of rotary drilling rig:

1. Failure phenomenon: the drill pipe slowly falls after the shutdown

Analysis of the problem: the gap between the friction plates is too large

Treatment method: replace the friction plate

Discrimination method: The drill pipe slides down automatically after the machine is stopped

2. Fault phenomenon: the floating solenoid valve is stuck and the pump is not in the neutral position

Problem analysis: cleaning valve core or water pump solenoid valveTurkey Excavator sprocket

Treatment method: After the electrical plug is unplugged, the solenoid valve of the manual water pump

3. Fault phenomenon: the main hoist only has the lowering actionTurkey Excavator sprocket

Analysis of the problem: the motor relief valve is stuck, so that the press cannot be returned

Treatment method: remove the motor relief valve and clean it, and then reassemble it

Identification method: The quantitative motor is lowered to the A port overflow valve

4. Failure phenomenon: the main winch appears to drop when the drill pipe is pumped

Analysis of the problem: the motor relief valve is stuck, so that the press cannot be returned

Treatment method: remove the motor relief valve and clean it, and then reassemble it

Identification method: the quantitative motor is lowered to the B port relief valve

5. Fault phenomenon: the mast is not synchronized

Problem analysis: The drill pipe bolt damping hole drill bit in the large cavity of the oil cylinder is inconsistentTurkey Excavator sprocket

Treatment method: need to replace the hinge bolts of the same size process pump

Identification method:

6. Failure phenomenon: the mast is not vertical

Problem Analysis: The level sensor is damaged and needs to be replaced

Identification method: use theodolite to measure the verticality of the mast

7. Failure phenomenon: the lifter is inflexible or unable to rotate

Analysis of the problem: the elevator has not been used for a long time and the machine has not been rustedTurkey Excavator sprocket

Treatment method: disassemble and replace damaged parts

8. Fault phenomenon: insufficient torque of power head

Problem Analysis: Insufficient engine power, abnormal engine noise, black smoke, speed loss

Treatment method: Check the cause of the engine failure and replace the engine equipment with the appropriate powerTurkey Excavator sprocket
