The service life of pneumatic water well drilling rig is affected by various factors, generally speaking, its normal service life is around 8-15 years. Here are some factors that affect its lifespan:
Working environment:
In harsh working conditions such as high temperature, high humidity, high dust, corrosive environment, etc., drilling rigs are prone to corrosion, wear and tear, which can shorten their service life. For example, when used in damp and high salt environments such as the seaside, the metal parts of the drilling rig are more prone to rusting and corrosion, and their service life may be reduced by 3-5 years compared to using in dry and clean environments.
Maintenance and upkeep:
Regular comprehensive and standardized maintenance and upkeep can promptly identify and address potential issues, replace worn parts, maintain the drilling rig in good working condition, and extend its service life. On the contrary, drilling rigs that lack maintenance and upkeep are prone to malfunctions and their service life will be greatly shortened.
If operated correctly, maintained regularly, and vulnerable parts are replaced in a timely manner according to actual conditions during use, pneumatic water well drilling rigs can usually be used for 12-15 years or even longer; If not used properly and maintained properly, serious malfunctions may occur within 8-10 years, making it impossible to function properly.

Daily maintenance
1. Cleaning equipment:
After each day's work, compressed air or brushes should be used to remove dust, dirt, and debris from the surface of the drilling rig to prevent them from entering the interior of the rig and accelerating component wear. Special attention should be paid to cleaning the surfaces of vulnerable components such as drill bits, drill rods, and impactors to maintain their cleanliness.
2. Check component connections:
Carefully check whether the connecting bolts, nuts, etc. between the various components of the drilling rig are loose. If they are loose, they should be tightened in a timely manner. Especially at the connection part of the drill rod, if the connection is not firm, it is easy to shake during drilling, leading to increased wear and even breakage of the drill rod.
3. Lubrication components:
Lubricate each lubrication point of the drilling rig according to the requirements of the equipment manual. Generally speaking, the gears, bearings, chains, and other parts of the drilling rig need to be regularly coated with lubricating oil or grease to reduce friction and minimize component wear. For example, the main lubrication points of the drilling rig should be inspected and lubricated at least once a week.
regular maintenance
4.Replacing filters:
Air filters, oil filters, and fuel filters may become clogged after a period of use, affecting the normal operation of the drilling rig. The filter should be replaced regularly according to the operating environment and working hours of the drilling rig. Usually, the air filter needs to be replaced every 200-300 hours of work; Replace the oil filter and fuel filter every 500-600 working hours.
5.Inspect vulnerable parts:
Conduct a comprehensive inspection of the vulnerable parts of the drilling rig at regular intervals, such as monthly or quarterly. In addition to the visual inspection during daily maintenance, it is also necessary to use professional tools to measure and evaluate the wear of components. For example, using a caliper to measure the diameter wear of a drill bit, using a dial gauge to measure the curvature of a drill rod, etc. For components with wear approaching the limit, they should be replaced in a timely manner to avoid affecting the performance of the entire drilling rig due to component damage.
6. Maintaining the air compressor:
The air compressor is an important component of the pneumatic water well drilling rig, and its performance directly affects the efficiency of the drilling rig. Regularly discharge the accumulated water in the compressor storage tank to prevent moisture from entering the pneumatic system and corroding components. At the same time, check the tightness of the belt of the compressor. If there is any looseness, adjust it in a timely manner to ensure the normal operation of the compressor.
Special maintenance
1. Long term parking and maintenance:
If the drilling rig needs to be parked for a long time, it should be thoroughly cleaned and maintained first. The surface of the drilling rig should be cleaned of oil, dust, etc., and rust proof oil should be applied to the parts that are prone to rusting. Then park the drilling rig in a dry and well ventilated indoor area, avoiding direct sunlight and rain. During the parking period, the drilling rig should be started and tested at regular intervals to check the performance of each component and prevent rusting or damage caused by prolonged parking.
2. Maintenance after use in harsh environments:
When the drilling rig is used in harsh environments such as high temperature, high humidity, dusty or corrosive environments, special maintenance should be carried out in a timely manner. After use in a dusty environment, it is important to clean the air intake and exhaust ports of the drilling rig to prevent dust from entering the interior of the rig; After use in corrosive environments, the surface of the drilling rig should be rinsed with clean water, and then coated with anti-corrosion paint or rust proof oil to protect the metal parts of the drilling rig.
