Product Description ： The YGQZ-500 is a compressed-air-powered deep-well drilling rig with a rated drilling depth of up to 500 meters and a borehole diameter range of 100–254 mm. Utilizing the Down-the-Hole (DTH) percussion drilling principle, it employs high-pressure air to drive a DTH hammer that breaks up rock, while simultaneously using air pressure to discharge cuttings from the hole. The equipment has minimal water requirements for operation, enabling efficient performance even in arid, water-scarce regions. With its robust, reliable structure and excellent adaptability to field conditions, it is an ideal choice for deep-well development.
Product Features: 1. High drilling speed in hard rock: Uses down-the-hole (DTH) impact to break rock, offering significantly higher efficiency in hard rock formations compared to mud rotary rigs. 2. Dry pneumatic cuttings removal: Eliminates the need for large volumes of drilling fluid, making it ideal for well-drilling operations in water-scarce mountainous regions or remote sites without a water source. 3. Simple operation: Features centralized hydraulic controls that reduce manual labor; the unit is equipped with comprehensive safety protections, ensuring greater safety during field operations. 4. Versatile applications: Suitable not only for deep water well drilling but also for drilling blast holes, geological sampling holes, shallow geothermal holes, and more. 5. Easy maintenance: Core components feature a modular design, and wear parts are simple to remove and replace, thereby reducing long-term maintenance costs.
