Recently, the reverse circulation drill series launched by Shandong Zhengyuan Drilling & Production Intelligent Equipment Co., Ltd. has officially hit the market. Boasting the core advantages of high efficiency, environmental friendliness, multi-functionality and strong adaptability, these drills have become a new preferred choice for geological exploration, water well drilling, mine construction and other fields, gaining high market attention immediately upon launch.
As a well-known brand in the domestic drilling rig industry, Shandong Zhengyuan has been deeply engaged in the R&D and manufacturing of drilling and production equipment for many years. The newly launched reverse circulation drill series is a high-quality masterpiece developed by the company based on market demand and cutting-edge technologies. The products fully adopt advanced foreign RC drilling technologies and are equipped with double-wall drill pipe design. They efficiently collect and discharge slag through cyclone collectors, and are matched with air compressor air supply slag discharge systems. Compatible with medium and high air pressure series hammers and various drill bits, these drills can easily handle various complex formations such as loose layers and bedrocks, realizing compressed air reverse circulation DTH drilling. With a drilling depth ranging from 300 to 600 meters and a drilling diameter of 105 to 500 mm, the footage efficiency can reach 10-35 m/h, greatly improving construction efficiency.
In terms of core configuration and operation design, this series of reverse circulation drills fully reflects professionalism and user-friendliness. The whole machine adopts a diesel engine-driven full hydraulic system. All processes including drill frame lifting, rotary feeding, outrigger leveling and crawler traveling are controlled by hydraulics. Equipped with rotary motors from a US-funded enterprise, the two-point drive design features low failure rate and large torque, allowing flexible adjustment of rotary speed and drilling axial pressure according to working conditions. An independent hydraulic oil radiator ensures continuous operation in high-temperature outdoor environments. The multi-functional hydraulic jack enables automatic leveling of the machine body and loading/unloading without additional lifting equipment. Meanwhile, the product is equipped with an exclusive simple cab, which effectively isolates harsh outdoor environments and reduces the labor intensity of operators. The standard modular design supports flexible switching between crawler chassis and vehicle-mounted type. The crawler traveling system has a climbing capacity of 21° and a small turning radius, enabling flexible movement and construction even in narrow and muddy working conditions.
In addition, the series of reverse circulation drills pursue excellence in details and quality. The drill centralizer combined with a level ensures high hole-opening accuracy. The compensating slide plate effectively protects drill pipe threads and extends service life. The reliable air pre-filtration system is suitable for harsh working conditions, reducing engine wear. The specially designed oil mist lubricator continuously lubricates the hammer, further improving equipment durability. The full hydraulic control allows flexible adjustment of parameters such as rotation speed and propulsion speed, adapting to various processes such as DTH drilling and air-lift reverse circulation drilling. It can also be equipped with accessories such as mud pumps, generators and foam pumps according to user needs, realizing multi-purpose of one machine and greatly reducing the cost per meter of drilling.
Adhering to the core concept of "building high-quality drilling and production equipment to empower engineering construction efficiency", Shandong Zhengyuan's launch of reverse circulation drills is not only an accurate response to market demand, but also a reflection of its technical strength. At present, this series of products has fully opened for pre-order. With the core advantages of high cost performance, strong adaptability and high stability, it has become a popular choice for engineering construction units all over the world.
Moving forward, Shandong Zhengyuan will continue to deepen its layout in the drilling and production equipment field, increase R&D investment, continuously optimize product performance, provide more professional, efficient and reliable drilling solutions for global customers, and contribute to the high-quality development of the drilling engineering industry.
