Crawler mobile drilling rig pneumatic drill mining Water pneumatic dual-purpose water well drilling rig
Water Well Drilling Rig introduce
ST series deep(water) well drlling rig uses full hydraulic control
and the top drive to drive the rotation of drilling tools with very
high drilling efficiency. Reasonable overall layout uses the
tractor-mounted or all terrain chassis for transportation with good
maneuverability. Very flexible in difficult roads, it can be widely
used in many fields such as resource exploration of hydrology
wells, coalbed methane, shallow layer of shale gas, terrestrial
heat, etc, and can also be used for coal-mine gas exploitation or
salvage work.
The top-mounted driving head principal shaft has a great drift
diameter,which is suitable for many kinds of construction work such
as slurry drilling, air drilling, and air foam drilling, meeting
the demands of well-drilling in different terrain strata.

Water Well Drilling Rig Performance Characteristics
* Mature and reliable hydraulic top drive power head with large
bearing capacity and good sealing effect.
* The gap adjustable telescopic drill collar can meet the
requirements of long casing construction and has high work
eficiency.
* Unique hydraulic matching technology for high system efficiency.
* Integrated visualization pressurize and pressurize decompression
feed system for fine adjustment of diling pressure according to
dilling depth.
* Four hydraulic high supporting legs are provided to achieve rapid
leveling of the rig without liting. The swing-type centering device
provides a wide working space when working.
Common faults and maintenance methods of drilling rigs:
Fault 1: Insufficient pressure in the hydraulic system of the drilling rig, and fatigue of the pressure regulating valve requires adjusting the limit nut or replacing the spring.
Fault 2: The drilling rig coupling heats up and the elastic ring is excessively worn; The reason is that the coaxiality between the drilling rig power machine and the clutch is poor, and it is necessary to improve the assembly coaxiality;
Fault 3: If the oil pump of the drilling rig fails to start or the oil level is insufficient, first check the oil level in the oil tank and add oil to the oil level line. If the fault is still not resolved, check whether the filter is blocked. In addition, check whether the oil tank vent is blocked or if the oil suction pipe joint is loose and intake is caused;
Fault 4: The hoist brake of the drilling rig slips, mainly due to oil stains inside the brake band that need to be removed; If there is no oil stains, check the gap between the brake band and brake wheel. If it is too loose, adjust it appropriately;
So, it is necessary for operators to regularly clean, maintain, and upkeep the drilling rig, promptly identify the root cause of problems and take action, so that the use time of the drilling rig will be longer.
