How To Keep Your Rotary Drill Working Smoothly For Longer

In the fields of construction, mining, and geological exploration, rotary drilling rigs are one of the core equipment and undertake key tasks. Whether it is a newly purchased equipment or a used rotary drilling rig, good maintenance can significantly extend the service life and improve the working efficiency. Especially for high-intensity working equipment such as crawler rotary drilling rigs, scientific management is essential.

What is a rotary drill, and how does it work?

A rotary drilling rig machine is a is a professional equipment that uses a rotating drill bit to drill holes in underground rock and soil. It uses the power head to drive the drill rod to rotate, and pushes the drill bit into the formation through pressure and torque. It is widely used in projects such as piling, foundation construction, and deep well drilling. Crawler rotary drilling rigs have good mobility and are suitable for operations in complex terrain.

10 tips for maintaining rotary drilling rigs

Regularly replace hydraulic oil and grease

The hydraulic system is the "heart" of the rotary drilling rig unit, and the cleanliness of the hydraulic oil directly affects the performance of the whole machine. It is recommended to replace the hydraulic oil at the time interval required by the manufacturer, and use high-quality grease to lubricate key components such as the turntable and slewing mechanism to prevent dry grinding and wear.

Check and clean the filter and cooling system

The blockage of the filter will lead to a decrease in the heat dissipation effect of the system, and in severe cases, may cause damage to the hydraulic pump. They should be disassembled and cleaned regularly. The fan and radiator of the cooling system should also be kept clean to ensure that the temperature of the engine and hydraulic system is within a reasonable range to extend the service life of the equipment.

Check the wear of the drill rod and drill bit daily

Drill pipes and drill bits are high-wear parts that are in direct contact with the formation, so operators should check whether the drill pipes and drill bits have cracks, bends or excessive wear before and after operations. If there is a problem, they should be replaced in time to prevent breakage during drilling and affect the progress of the project.

Tighten loose bolts in time

Vibration operation can easily cause some bolts to loosen. It is necessary to regularly inspect the connection parts of the equipment, especially the key parts such as the power head, slewing bearing, crawler chassis, etc., and tighten them in time to avoid safety accidents caused by parts falling off.

Perform preheating and shutdown operations according to the manual of the rotary drilling rig

Preheating should be performed before starting the cold machine to avoid damage to the pump station due to excessive viscosity of the hydraulic oil. When shutting down, unload the pressure first, and then gradually shut down the system to prevent sudden power failure from causing impact on the system, ensuring that the crawler rotary drilling rig runs more smoothly and reliably.

Control the speed and pressure during operation to avoid overload

Reasonable control of speed and drilling pressure is the key to ensuring the stable operation of equipment. Excessive speed or pressure will not only damage the drilling tool but also the power system. During operation, parameters should be adjusted according to geological conditions to avoid overload operation.

Check whether the electrical system connection is reliable

The stability of the electronic control system directly affects the safety and reliability of the entire machine operation. Check whether the wire plug, sensor, electric control box, etc., have poor contact, wear, or water ingress problems to prevent abnormal operation of the equipment due to short circuit or signal loss.

Avoid long-term no-load operation

If the equipment runs no-load for too long, it will cause fuel waste and additional wear of mechanical parts. When not in operation, the engine should be turned off in time, or the system operation frequency should be reduced, which is energy-saving and helps to reduce the failure rate.

Regularly inspect and maintain the crawler chassis

The crawler is the core moving component of the crawler rotary drilling rig. The crawler tension, chain wear, and whether the supporting wheels are lacking oil or damaged should be checked regularly to keep the walking system flexible and efficient.

Record maintenance logs to form equipment files

Every repair, maintenance, and parts replacement should be recorded in detail to establish a complete equipment use file. This not only helps to understand the status of the equipment, but also provides a reference when the equipment is transferred or evaluated, and improves the residual value of the drilling rig for sale.

Why do people prefer to buy second-hand rotary drilling rigs? 

Due to the high price of new drilling rigs, many construction units choose used rotary drilling rigs as an alternative. High cost performance, low maintenance cost, and short delivery cycle are its main advantages. Under the premise of ensuring that the equipment is in good condition, choosing a drilling rig for sale can not only be put into use quickly, but also reduce project costs.

Conclusion

Whether you are using new or second-hand equipment, scientific maintenance is the key to ensuring the long-term stable operation of the rotary drilling rig. Through regular inspections and professional maintenance, you can significantly extend the life of the rotary drilling rig unit, improve operating efficiency, and ensure efficient progress of the project.
