Product Description
Water Well Borehole Portable Pneumatic Diesel Drilling Crawler Machine Rigs
Introduction of pneumatic drilling rig
It is widely used for water well drilling, geothermal air-conditioning project and other boreholes, especially applicable to mountain area and rock formation water engineering.
Much higher efficient than the traditional mud rotary drill rigs, creating the considerable economic benefit for users. Especially solve problems to drill hard rocks that the traditional rotary drilling rig meet and it should work with air compressor.
When drill soft underground formation, it is OK to use mud rotary drilling, and there is mud drilling swivel system.

Characteristics of pneumatic rock drilling
Strong and reliable power
1. Adopt famous brand four cylinder diesel engine as power, large power, small volume, small vibration and stable operation.
2. The perfect combination of a patented diesel engine intake regulator with a pre-filter, oil filter and paper filter enhances the adaptability of the drilling rig to harsh environment and prolongs the service life of the diesel engine.
Powerful propulsion and slewing mechanism
1. The new rotary mechanism is composed of a cycloid hydraulic motor with large torque and a planetary reducer, which provides a powerful torque reserve for the drilling rig and reduces the probability of sticking.
2. The combination of hydraulic cylinder and pulley can produce 20KN lifting force, adjust the pressure regulating valve on the propulsion control valve, and obtain the optimum propulsion force needed in the working condition.
