Product Description
The YGQZ-300 pneumatic water well drilling rig is a high-efficiency, multi-functional down-the-hole drilling equipment engineered for complex geological conditions including soil, clay, sand, and hard rock layers. Widely adopted in farmland irrigation, engineering water supply, residential domestic water supply, and groundwater exploration projects, this drilling rig delivers stable and reliable drilling performance, especially suitable for tough mountainous and rocky area water intake projects. Featuring simple operation, stable running status and low failure rate, it is an ideal core device for various civil and industrial water well drilling operations.
Features of the YGQZ-300 Water Well Drilling Rig: 1. It is a highly efficient and multifunctional downhole drilling rig, suitable for drilling water wells, irrigation wells, geothermal wells, and various other types of boreholes. It is especially effective for water extraction projects in mountainous and rocky areas.
2. The rig is capable of drilling in various formations (rock layers, clay, sand) with a maximum hole diameter of up to 300mm.
3. The machine uses a high-torque hydraulic motor powerhead and a branded diesel engine. The hydraulic control system is equipped with large-diameter hydraulic cylinders. The diesel engine has a two-stage air filtration system for protection and can also use clean air from a compressor.
4. The unique cam design and centrally controlled operating system make it easy to maintain and operate the machine.
5. The rig uses an excavator crawler chassis, providing excellent off-road capabilities. It can also be mounted on a truck for greater mobility.
6. Dual gear rotation and feed speeds allow the rig to work effectively in both soil and rock formations.
7. The system can be upgraded with dual systems: 1) Pneumatic system with an air compressor 2) Mud pump system with a mud pump.
