Analysis of Rotary Drilling Rig Technology at Home And Abroad

Rotary drilling RIGS, as key equipment for pile foundation construction, are widely used in the construction field both at home and abroad. Due to the differences in research and development history and industrial foundation among various countries, technologies present their own characteristics. Understanding the technical differences between domestic and foreign rotary drilling RIGS can help China draw on advanced experience and promote the progress of the industry.

1. Power system technology: Foreign brands such as Bauer from Germany mostly adopt high-performance engines, which are powerful and have excellent fuel economy. Some domestic enterprises have also made technological breakthroughs. For instance, Sany's electric rotary drilling rig has achieved zero emissions and remarkable energy-saving effects.

2. Degree of automation and intelligence: European and American products are equipped with advanced sensors and intelligent control systems, which can automatically monitor and adjust drilling parameters. In recent years, the domestic development has been rapid. The Yutong motor direct drive pure electric rotary drilling rig has a sensitive and precise electrical control system, making the operation more intelligent and efficient.

3. Hydraulic system performance: The hydraulic systems of well-known foreign brands are mature, with stable pressure and fast response speed, which can ensure the efficient and stable operation of the drilling rig. Domestic enterprises have been continuously improving, and the performance of hydraulic components has gradually improved, narrowing the gap with foreign counterparts.

4. Drill pipe and drill bit design: Abroad, emphasis is placed on the innovation of drill pipe materials and structures to adapt to complex strata. In China, various types of drill bits have been developed for different geological conditions, such as alloy drill bits, to enhance rock-breaking capabilities.

5. Manufacturing process and quality stability: With its profound industrial accumulation, foreign countries have exquisite manufacturing processes, and their equipment is highly durable and reliable. Domestic enterprises have strengthened process management, and the quality of their products has steadily improved. Some products have reached international standards.

6. Service and After-sales System: Foreign enterprises have a global layout, and their after-sales response is prompt, capable of providing timely technical support. Domestic enterprises are also improving their service networks, enhancing service levels and shortening service radii.

The rotary drilling rig technologies at home and abroad each have their own advantages and disadvantages. It started early abroad and has rich experience in power, hydraulics, manufacturing processes and other aspects. The domestic development is rapid, and breakthroughs have been made in the fields of electrification and intelligence. In the future, domestic and foreign technologies are expected to integrate with each other. Domestic enterprises need to increase investment in research and development, enhance their core competitiveness, and push the technology of rotary drilling RIGS to a new height to better serve the construction industry.
