HFPV-600 is a tracked hydraulic drilling rig developed by Hanfa Design, specifically designed for photovoltaic solar pile driving and other complex working conditions. It adopts new hydraulic technology and features low energy consumption, high torque, and flexible hole movement.
Its advantages lie in its compact structure and stability: the propulsion carriage is equipped with telescopic compensation function, which directly supports the ground during drilling, effectively reducing vibration and improving positioning accuracy.
In addition, it supports multi-mode operations and is compatible with hammer drilling (diameter 90-400mm) and spiral drilling (maximum 400mm), suitable for rock hardness range F=6-20, and suitable for penetration needs from soft soil to medium hard rock layers.
2、 Equipment features
- 1. Core parameters
Power system: The main engine has a power of 92kW, a rated speed of 0-110r/min, and a slope crossing ability of 35 º, suitable for complex terrain.
Drilling ability:
Hammer drilling: depth 20-120m, air pressure 0.7-2.46MPa (medium/high pressure switching), air consumption 10-26m ³/min.
Spiral drilling: depth 0-30m, spiral tube diameter 130-400mm, single thrust length 3200mm.
Mechanical design: The turntable has a tilt angle of 120 º, and the total angle of the drilling arm swinging left and right is 50 º, supporting multi angle operations.
Size and weight: 5300 x 1970 x 2620mm (length x width x height), with a total weight of 5800kg, balancing mobility and operational stability.
- 2. Energy efficiency and adaptability
By optimizing the hydraulic system to reduce energy consumption, equipped with multi speed regulation (0-110r/min), the drilling efficiency is improved. Air compression can switch between medium and high pressure, enhancing the ability to penetrate hard rocks.
3、 Solar energy system workflow
Solar panels convert light energy into electrical energy → energy storage system buffers → inverter power supply → drives hydraulic motors to complete drilling operations. This design can reduce dependence on traditional fuels, but it should be noted that the main power of the equipment still relies on a 92kW engine, and solar energy may be used as an auxiliary energy source.
4、 Application scenarios and engineering cases
- 1. Main application areas
Photovoltaic power station construction: precise installation of solar support pile foundations, suitable for complex terrains such as mountains and deserts.
Basic engineering: anchoring of water conservancy facilities, bridge pile foundations, and drilling of blasting holes in open-pit mines.
Special working conditions: water well drilling, DTH (down the hole hammer) blasting construction.
- 2. Typical cases
Mountain photovoltaic project: Install spiral piles on a slope of 35 º, with a daily drilling efficiency of 30-50 piles, significantly reducing the construction period.
Mining blasting hole operation: Penetrating through rock layers with F=18, drilling to a depth of 100m, and using high-pressure air system to achieve efficient crushing.
5、 Difference
- 1. Comparison with traditional equipment
Efficiency advantage: The hydraulic system of HFPV-600 provides higher torque (more than 30% higher than traditional mechanical drilling rigs), and the hole and displacement speed is faster, reducing non operational time.
Cost effectiveness: Although the initial investment is high, its low gas consumption and low maintenance requirements can reduce long-term operating costs, and the comprehensive energy efficiency ratio can be improved by about 25%.
- 2. User feedback
Positive evaluation: The equipment has strong stability, especially outstanding performance in hard rock conditions; Quick after-sales service response, providing one-year warranty and on-site technical guidance.
Improvement suggestion: Some users have pointed out that the propulsion efficiency of the spiral drill module in soft soil layers needs to be optimized.
summarize
HFPV-600 has become an important equipment in photovoltaic engineering and complex geological operations due to its high adaptability, low energy consumption, and reliability. Although the specific configuration of the solar energy system needs further clarification, its technical parameters and application cases have fully demonstrated its advantages in efficiency and cost control. Future technological iterations are expected to strengthen the integration and intelligence of clean energy, promoting sustainable development in the industry.
