The pneumatic 1000 water well drilling rig has the following advantages:
1. High drilling efficiency: Adopting the principle of pneumatic impact, it uses compressed air to drive the impactor, which can generate high-frequency impact energy. It has a high efficiency in breaking rocks and can also drill quickly in areas with a large amount of rocks such as mountainous areas. For example, some drilling rigs can drill 35 - 40 meters per hour.
2. Adaptable to multiple strata: It can be used in conjunction with medium and high wind pressure series impactors and can operate under various geological conditions such as loose layers and bedrock. It can effectively drill in soil layers, gravel layers, or hard rock layers.
3. Large drilling diameter: The drilling diameter can usually be adjusted within a certain range, such as 130 - 350 millimeters, which can meet the needs of different water well construction projects.
4. Strong power: Generally equipped with high-power engines, such as imported Cummins engines or Yuchai engines, etc., it provides strong power support to ensure the stable operation of the drilling rig under various working conditions.
5. Flexible movement: Some pneumatic 1000 water well drilling rigs use crawler chassis, which have strong cross-country performance and can easily cope with various complex working sites. They can also be equipped with hydraulic high outriggers, which are convenient for loading and unloading the vehicle and leveling the drilling rig, saving hoisting costs.
6. Simple operation: Most of the actions are realized by the hydraulic system, such as the lifting of the drilling rig tower, the connection and disassembly of drill pipes, rotation, feeding, outriggers, winch and other actions. This reduces the labor intensity of operators and enables flexible drilling at multiple angles.
7. Strong slag removal ability: Using compressed air as the power source, during the drilling process, high-pressure air can quickly discharge the rock cuttings out of the hole, effectively avoiding the accumulation of rock cuttings in the hole, improving the drilling efficiency, and at the same time, it is beneficial to maintaining the stability of the borehole wall.
8. High safety performance: The pneumatic drilling rig itself has the characteristics of safety and explosion protection, and it is relatively safe to use in environments with flammable and explosive gases. It is also equipped with various safety devices. For example, the hydraulic outriggers can ensure the stability of the drilling rig during construction and reduce potential safety hazards.
