Product Introduction
Features of ZJD2800 hydraulic reverse circulation drilling rig
1. Full hydraulic continuously variable transmission is equipped with imported transmission components, which has reliable and stable transmission performance, adopts frequency conversion motor, which is efficient and energy saving. Reasonable optimization of power configuration, strong and powerful, high work efficiency, fast hole formation.
2. The hydraulic and electrical dual-circuit control system increases the reliability of equipment operation. The electrical control system adopts PLC, monitoring screen. wireless communication module and combines manual control to form a dual-circuit control method, which can be remotely controlled by remote control or can be manually completed operation.
3. Full hydraulic power rotating head, providing large torque and large lifting force to overcome complex formations such as gravel and rocks and hard rock formations.
4. The operating system is a combination of wireless remote control, manual and automatic operation.
5. Optional counterweight to pressurize the bottom of the hole to ensure the verticality of the hole and improve the drilling efficiency.
6. A dual-mode operating system with intelligent operation and wireless operation. The intelligent system uses advanced sensor technology to display real-time operating parameters of equipment, real-time storage and printing of construction data, multi-point video monitoring system combined with GPS positioning, GPRS remote real-time transmission and monitoring of drilling rig site operations happening.
7. It is relatively small in size and light in weight. It is easy to disassemble the drilling rig. All electrical and hydraulic connectors involved in disassembly and assembly use aviation plugs or quick connectors, and structural parts have disassembly and assembly signs.
8. Tilting suspension power head and tilting frame, combined with hydraulic auxiliary crane, compact and reasonable structure, safe and convenient to disassemble and assemble drill pipe and drill bit.
9. Large-diameter drill pipes and double-walled drill pipes adopt high-pressure gas lift sealing device and advanced RCD construction method to achieve fast footage.
10. The operation room is installed on the working platform, which is convenient for operation and comfortable environment. The temperature adjustment equipment can be installed on your own.
11. Optional stabilizer to assist drilling to control the verticality and hole accuracy and reduce drill tool wear.
12. The equipment configuration function can be selected according to actual construction needs, with specific efficiency and diversified choices:
A. Install inclined platform feet for inclined pile construction;
B. Drill rod auxiliary crane with hydraulically driven telescopic boom and hydraulic hoist;
C. The mobile walking system of the drilling rig (walking or crawler);
