As a kind of high-intensity, long-time running engineering equipment, the stability and service life of water well drilling rigs have a great impact on the construction efficiency and economic benefits.

Whether it is vehicle-mounted, tracked or trailer-mounted water well drilling rigs, if there is a lack of scientific and systematic daily maintenance management, it will not only shorten the life of the equipment, but also may break down in critical projects, causing unnecessary losses.

In this article, we will systematically explain how to properly maintain water well drilling rigs from four aspects: daily maintenance, regular maintenance, replacement of wearing parts and usage habits.

Daily maintenance: basic but critical

a. Pre-operation checks

Before each operation, you must routinely check whether the hydraulic oil level, fuel, battery voltage, coolant and lubrication system is normal. Timely elimination of hidden dangers such as oil leakage, loosening, abnormal sound.

b. Monitoring during operation

During the operation of the equipment, real-time attention should be paid to whether the oil pressure, temperature, rotating torque, pump pressure and other parameters are within the normal range.

Once abnormal vibration and pressure fluctuation occurs, stop the machine immediately for inspection.

c. Cleaning after operation

After operation, the mud, oil and debris attached to the drill pipe, drill bit, pump body and base should be cleaned to prevent corrosion and accumulation leading to wear of parts.

Regular maintenance: preventing failures in advance

a. Hydraulic system maintenance

Hydraulic system is the core of water well drilling rig, it should replace the hydraulic oil and clean the filter element once every 300-500 hours of work, and check whether the hydraulic pump, control valve, and oil pipe interface are aging or blocked regularly.

b. Power system maintenance

The engine should change oil, air filter and diesel filter regularly to keep the air intake smooth and oil supply clean. Battery terminals should be kept clean and firm to avoid oxidation.

c. Inspection of structural parts

Check whether there are cracks, deformation, loose bolts, etc. on the slewing bearing, guide rail, main frame, etc., and tighten or weld them in time to avoid structural hidden danger.

Replacement of wearing parts: maintenance instead of repair

Drill bits and drill pipes

Drill bits are high-frequency consumables and should be replaced in a timely manner according to the wear and tear of the ground to avoid ‘working with disease’.

Drill pipes should be replaced in time according to the wear and tear of the ground to avoid ‘sick operation’. Drill pipes should pay attention to whether they are bent or thread damage to prevent breakage, which may lead to jamming.

Belt and seals

Transmission belt will be aged and loose after long-term use, and should be adjusted regularly or replaced.

Seals, bearings, gaskets, etc. should be replaced in time according to the length of use and the environment, so as to avoid leakage of the hydraulic system or a decline in efficiency.

Good operating habits are the basis of security

a. Strictly according to the norms of operation

Prevent brutal operation, frequent starting or overloading, which will accelerate component fatigue and system aging.

b. Establish equipment maintenance files

Record each maintenance, repair and replacement, forming a ‘medical report’ of the equipment, which can pre-judge the failure points and improve the management level.

c. Train operators

The technical level of operators directly affects the use of equipment. Enterprises should organise regular technical training to improve the team’s understanding of the equipment and maintenance awareness.

Conclusion

Maintenance is not a cost, but a ‘value-added investment’ in equipment. A well-maintained water well drilling rig can not only significantly improve the working efficiency, but also greatly extend its service life and reduce the failure rate and repair costs.

We recommend that customers consider maintenance as part of their daily work, and establish a scientific maintenance management system by combining the technical support and service programmes of the manufacturer.
