300M Hydraulic Water Well Drilling Rig Pneumatic Crawler Drill For Multi Function
Introduction to drilling rig
pneumatic crawler water well drilling rig 300m, is a kind of top driven high efficiency and multifunctional hydraulic drilling rig with advanced technology, convenient operation, high working efficiency, reliability and durability. It is widely used in drilling wells, inspection wells, precipitation wells, rescue wells, Ground source air conditioning holes, CBM, natural gas, oil extraction and other projects. this machine can drill holes with air compresse in all formations , the drilling speed is very fast when drill the hard rock , which hardness is f=4-20.

Characteristics of drilling rigs
1. This pneumatic water well drilling machine has the compact body. The fuselage width only 1.9 meters, fully suitable for farming courtyard home drilling or other narrow condition drilling. Drilling depth up to 240-300 meters.
2. Fully hydraulic control is convenient and flexible: can adjust the drilling speed, torque, and promote axial pressure, anti-axial pressure, propel and improve the speed to meet the different conditions use of drilling tools and different construction needs.
3. Multi-function drilling: A variety of drilling processes can be used on this rig, such as: DTH drilling, mud drilling, roller cone drilling, drilling with the follow-pipe and the being developed core drilling, etc. This drilling machine can be installed, according to user needs, mud pump, generator, welding machine, cutting machine. Meanwhile, it also comes standard with a variety of winch.
4. High leg crawler type: high leg is easy for loading and unloading, no need of crane in truck loading. Crawler walking is more adapt to the movement in muddy field.
How can we do a good job in the maintenance of well drilling rig? Today, I'll talk about the five steps of well drilling rig
1. Pay attention to check whether the bolts and nuts of water and gas pipelines and various accessories of the drilling rig are firm at any time
2. . Always check the lubricating oil condition of the wind motor
3. . When the working face is immersed in water, a large-diameter drill head shall be used to insert the drill pipe when opening the hole, so that the drill pipe is 1-2 meters above the water surface to prevent mud and rock slag from falling into the hole
4. . The drilling rig is not allowed to reverse during drilling operation, so as to prevent the drill pipe from falling into the hole
5.. When the drilling rig stops working for a short time, a small amount of air pressure shall be given to prevent sediment from invading the interior of the percussion device of the drilling rig. If the drilling rig stops working for a long time, the percussion device shall be lifted 1-2m away from the hole bottom for fixation
