Diesel Driven Hydraulic Portable 200m Pneumatic Water Well Boring Drilling Rig Machine
Introduction of 200 crawler type water well drilling rig:
ST200 series deep(water) well-drilling 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 full ground chassis for transportation with good maneuverability.Very
flexible in difficult roads and can be widely used in many fields such as resource exploration of hydrology wells, coalbed
methane, the shallow layer of shale gas, terrestrial heat, etc, and can also be used for coal-mine gas exploitation salvage work.
The top-mounted driving head principal shaft has a great drift diameter, suitable for many kinds of construction work such as
slurry drilling, air drilling, and air foam drilling, meeting the demands for well-drilling at different terrain strata.

Operating time characteristics of drilling equipment
1. Wear fast. Due to the processing, assembly and adjustment of new machine parts, the friction surface is rough, the contact area is small, and the surface pressure state is uneven, which speeds up the wear of the mating surface of the parts.
2. Poor lubrication. Because the fit clearance of newly assembled parts is small, and it is difficult to ensure the uniformity of fit clearance due to assembly and other reasons, the lubricant (fat) is not easy to form a uniform oil film on the friction surface, so as to reduce the lubrication performance and lead to abnormal early wear of parts.
3. Looseness occurs. Due to the influence of newly processed assembly parts, heat, deformation, rapid wear and other reasons, the original tightened parts can be easily loosened.
4. Leakage occurs. Due to the looseness, vibration and heating of the machine, leakage may occur on the sealing surface and coupling of the machine.
5. Operation error. Due to the lack of understanding of the structure and performance of the machine, misoperation is easy to lead to failure and even operation accidents.
