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.
