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.
