I. Motor failure

Motor failure is one of the most common failures of rock drills. When the motor fails to start, runs erratically, or is too hot, it indicates that the motor may have a problem. The causes of this kind of failure may be internal motor failure, power supply problems, poor wiring connections and so on. The solution is to check whether the power supply is normal, confirm whether the circuit connection is correct, and check the internal state of the motor.

Second, rock drilling hydraulic system failure

Failure of rock drill hydraulic system will lead to rock drill can not work properly, oil leakage, clogging and other problems. The main reasons for this kind of failure are pipe wear, oil seal aging, hydraulic system pressure is too high. The solution is to replace the damaged parts in time, check the quality of the pipeline regularly, clean the hydraulic system, and ensure that the pressure is controlled within the normal range.

Third, machine vibration

Machine vibration will reduce the service life and efficiency of the rock drill, and seriously affect the safety of the operator. The reasons for this kind of failure are wear and tear of rock drill bits, unstable positioning of rock drill, unequal foundations and so on. The solution is to replace the damaged parts, check the positioning stability, level the foundation and so on.

Insufficient knocking force

Insufficient knocking force will lead to rock drill can not effectively cut, aggravate the load on the equipment, resulting in damage to mechanical components. The causes of this failure are related parts damage, insufficient air pressure, etc.. The solution is to replace the damaged parts, check the air pressure to ensure that the rock drill can work normally.

Fifth, the cooling system failure

Cooling system failure will lead to rock drill overheating, reduce machine performance, affect the service life. The reasons for this kind of failure are water pump failure, radiator blockage and so on. The solution is to check all the parts of the cooling system, clean the radiator, and ensure that the water pump works normally.
