Rural Drought Resistant Pneumatic Water Well Drilling Rig Suitable For Various Geological Formations
Overview of ST-350 Pneumatic Drilling Rig
ST-350 series drilling rig is an efficient and versatile drilling and drilling equipment. It is mainly used for drilling
wells,agricultural irrigation wells, geothermal air-conditioning holes and other wells. It is especially suitable for water intake projects in mountainous and rock formations. . The efficiency is ten times higher than that of the traditional rotary drilling rig, and the economic benefits created for the users are extremely impressive. In particular, it solves the difficulty of drilling the soil air DTH hammer, the construction problem of the rotary rock drill with hard rock layer, gravel and pebble layer, and can work efficiently under various geological structures, achieving the perfect combination of rhinestone and air drilling.

Advantages of ST-350 Pneumatic Drilling Rig:
1. The pneumatic water well drilling rig is mechanical transmission, the other is hydraulic transmission, and the power is effectively utilized. The overall power loss is small and the drilling cost is low.
2. The water well drilling rig has more positive speed series and 14-500r/min speed range, and the output torque is 13428-250N.m.
3. The water well drilling rig adopts long-stroke double-speed mechanism and mechanical power head, and the power head stroke is 3800MM, which is used to improve drilling efficiency and reduce the occurrence of blockage and burning drill accidents.
4. The water well drilling rig adopts double oil pump for oil supply. When drilling, it uses single pump. When lifting the drill,it uses two pumps to merge; the power loss is small and the auxiliary time is short.
5. The rig has advanced structure and reasonable layout, which is convenient for maintenance, maintenance and repair.
6, using the crawler chassis, the leg cylinder stroke 1.5m can be automatically loaded, easy to move and transport.
7. The water well drilling rig is in machinery. Some functional interfaces are reserved in the hydraulic system, and the functions can be expanded according to the process requirements of different users.
Working principle
Drilling and rock breaking: The power drives the drilling tool to rotate (or impact), and the drill bit cuts/breaks the formation rock to form a borehole.
Slag discharge cycle: Mud (or compressed air) is injected into the drill pipe through a mud pump, carrying rock debris back to the surface from the gap between the borehole and the drill pipe, achieving continuous slag discharge.
Depth control: The winch is combined with a hydraulic feeding system to accurately control the speed and pressure of drilling tool lowering, ensuring the verticality of the borehole.
Well completion operation: After drilling to the target depth, insert the well pipe, fill the filter material, and complete the construction of the water well.
