Air Compresspor Mud Pump Crawler Underground Deep Water Well Borehole Drilling Rig Machine

ST 300 Crawler Mounted Drill Rig Descrption:

water well drilling rig is a lightweight, efficient, versatile drilling hole equipment, which borehole drilling machine is mainly applied in drilling wells, irrigation wells, geothermal wells and air holes for other purposes, especially for mountain and rock formation water engineering. The water well drilling rig machine can work on different formations, well drilling diameter up to 245mm. The drill machine adopts new hydraulic technology, supporting high torque hydraulic motor rotation and big bore drill hydraulic propulsion, branded multi-cylinder engine-powered two-stage air filter and the intake air compressor designed for hydraulic systems, extend the life of diesel engines. Unique pump design to facilitate maintenance, reduce maintenance costs. Centralized hydraulic control console, easy to operate.

What is the working principle of pneumatic drilling rig?

The pneumatic column drilling rig is powered by compressed air, supports the self weight of the drilling rig by the column, and carries the reverse torque and vibration generated in the drilling process. It can be widely used in the drilling construction of water exploration, water injection, pressure relief, gas exploration and drainage holes and geological exploration at different angles in mining wells.

Pre drilling inspection

1. Check whether the oil level, coolant and hydraulic oil of the drilling rig are sufficient.
2. Check whether the connecting screws of each part of the drilling machine are fastened.
3. The oil mist shall be added in time according to the use condition (it is forbidden to use the secondary polluted oil).
4. Check whether the left and right chains work hard at the same time and adjust them consistently
