Structural composition
Power system: mainly composed of air compressors, providing compressed air power for the drilling rig. Common types of air compressors include piston type, screw type, etc.
Drilling system
Drill rod: used to connect the drilling rig and drill bit, transmitting power and torque, allowing the drill bit to penetrate deep into the formation for drilling, and also serving as a channel for compressed air to enter the wellbore.
Drill bit: a component that directly acts on the formation, with various types depending on different geological conditions and drilling requirements, such as roller bits, diamond bits, down the hole hammer bits, etc. Its function is to break and cut rocks.
Pneumatic hammer or pneumatic motor: It is the core component of the drilling rig, which converts the energy of compressed air into mechanical impact or rotational motion to drive the drill bit to work.
Walking system: For some pneumatic water well drilling machines that require movement, they are equipped with walking mechanisms such as tracked or wheeled walking devices, which facilitate the movement and positioning of the drilling machine between different work sites, and improve the maneuverability and flexibility of the drilling machine.
Control system: used to control various operations of the drilling rig, such as drilling speed, rotation direction, lifting and lowering of drill rods, etc., generally including operating handles, buttons, pressure gauges, valves and other components. Operators use the control system to achieve precise control of the drilling rig and ensure the smooth progress of drilling work.
advantage
Efficient drilling: In hard rock formations, the drilling speed of pneumatic water well drilling machines is relatively fast, which can effectively improve construction efficiency.
Good maneuverability: The equipment is usually compact and can be equipped with tracked or wheeled walking devices, making it easy to move and operate in complex terrain conditions such as mountains and hills, and can reach areas with inconvenient transportation.
Suitable for various geological formations: especially suitable for drilling operations in hard rock formations such as granite, basalt, etc., and can also be applied in some loose formations.
Lower cost: Compared to some large hydraulic or electric drilling rigs, pneumatic water well drilling rigs have relatively lower purchase and operating costs, especially in areas with insufficient power supply or high power access costs, with obvious advantages.
Easy maintenance: Its structure is relatively simple, and maintenance and upkeep work are relatively easy. The required maintenance equipment and tools are also relatively few, reducing maintenance costs and downtime.
