Choosing a suitable pneumatic water well drilling rig requires
comprehensive consideration of multiple factors, and the following
are some key points:
Rock hardness:
For rock formations with high hardness, such as granite, quartzite,
etc., it is necessary to choose pneumatic water well drilling
machines with high impact energy and good drill bit wear resistance
to ensure effective rock fragmentation and improve drilling
efficiency. For example, some drilling rigs with high-pressure,
high flow air compressors can provide powerful impact power and are
suitable for drilling in hard rocks.
Stratigraphic structure: If the geological structure is complex,
with many fractures, faults, or unstable interlayers, the stability
and adaptability of the drilling rig need to be considered. A
drilling rig with good guidance and anti inclination function can
better cope with this situation, avoiding drilling deviation or
collapse.
Depth of water well
Shallow well:
For shallow water wells with a depth of less than tens of meters, a
typical small pneumatic water well drilling rig can meet the
requirements. This type of drilling rig has a simple structure,
easy operation, and low cost, and can quickly complete shallow well
drilling operations.
Deep well: When the depth of a water well exceeds hundreds or even
hundreds of meters, it is necessary to choose a pneumatic water
well drilling rig with high power, high drill pipe strength, and
good slag discharge capacity. At the same time, in order to ensure
the verticality and stability of the borehole, the drilling rig
should also be equipped with advanced inclinometer and correction
devices.

Routine maintenance
1. Check the air source:
Before starting up every day, check the working status of the air
compressor to ensure that the air pressure is stable and within the
range required by the drilling rig. At the same time, check whether
there is any air leakage in the trachea. If there is any leakage,
repair or replace damaged components in a timely manner.
2.Cleaning the drilling rig:
After each shift, the surface of the drilling rig should be
promptly cleaned of dust, oil stains, and debris to maintain its
cleanliness. Especially at the joints of drill bits, drill rods,
and the heat dissipation ports of the machine body, it is necessary
to ensure that there are no debris blockages to avoid affecting the
normal operation of the drilling rig.
3.Check the connecting components:
Before and after each shift, carefully check whether the connecting
bolts and nuts between the various components of the drilling rig
are loose. If any looseness is found, it should be tightened in a
timely manner. Special attention should be paid to the connection
between the drill rod and the drill bit, the connection between the
drill rods, and the connection between the drilling rig and the air
compressor to prevent safety accidents or affect drilling
efficiency due to weak connections.
regular maintenance
1. Replace lubricating oil:
According to the instructions of the drilling rig, regularly
replace the lubricating oil of each lubrication part of the
drilling rig. Generally speaking, a new drilling rig should undergo
its first oil change after running for a period of time (such as
50-100 hours), and then change it every certain working time (such
as 200-300 hours) thereafter. When replacing lubricating oil,
thoroughly clean the oil tank and lubrication system to ensure that
there are no impurities left.
2.Air filter maintenance:
The air filter is a key component that ensures the quality of air
entering the air compressor and needs to be cleaned or replaced
regularly. Generally, every 50-100 hours of work, the filter
element of the air filter should be cleaned, and compressed air can
be used to blow away the dust on the filter element from the inside
out; If the filter element is damaged or severely clogged, it
should be replaced with a new one in a timely manner to ensure
smooth air intake of the air compressor and improve work
efficiency.
3.Check worn parts:
Every certain working time (such as 100-200 hours), inspect the
drill bit, drill rod, impactor and other easily worn parts of the
drilling rig. Observe the wear of the drill bit, such as severe
wear of the alloy teeth and deformation of the drill bit body, and
replace the drill bit in a timely manner; Check whether the drill
rod has defects such as bending, wear, cracks, etc. If there are
any problems, the drill rod should be repaired or replaced in a
timely manner; At the same time, check the wear of the piston,
cylinder and other components of the impactor, and repair or
replace them if necessary.
Key component maintenance
1. Air compressor maintenance:
The air compressor is the power source of the pneumatic water well
drilling rig, and its maintenance is crucial. In addition to
regularly replacing the lubricating oil and air filter element, it
is also necessary to regularly check the tightness of the belt of
the air compressor. If the belt is too loose, it will cause the
speed of the air compressor to decrease, affecting the air pressure
output. The belt tension should be adjusted in a timely manner; At
the same time, check the cooling system of the air compressor to
ensure that the cooling water pipeline is unobstructed, the cooling
water pump is working properly, and prevent damage to the air
compressor due to overheating.
2. Control system maintenance:
The control system of the drilling rig includes various components
such as valves, pressure gauges, sensors, etc., and the working
status of these components should be checked regularly. Ensure that
the valve switch is flexible and there is no leakage; The pressure
gauge indicates accurately. If the pressure gauge reading is found
to be inaccurate, it should be calibrated or replaced in a timely
manner; Sensors should be kept clean and free of impurities such as
oil and dust to ensure accurate signal transmission and normal
operation of the control system.
