2. The unique pump set design is convenient for maintenance and reduces maintenance costs. 3. Centrally controlled hydraulic console for easy operation. 4. This series of drilling rigs adopts excavator crawler chassis with strong off-road performance. 5. The independent module design allows the drilling rig to be easily mounted on a truck, increasing its mobility. 6. Two-speed rotation and advance speed can meet different drilling needs in soil and rock layers. 7. The combined positioner can be adjusted and replaced according to different types of drill pipes and impactors to ensure accurate and reliable positioning and centering. 8. The structure of the hoist is convenient for the hoisting of the drill pipe and the impactor, and reduces the labor intensity.
The aspects should we pay attention to in the drilling process
Bit plays a very important role in the drilling of water well drilling rig, but the quality of a bit directly affects the efficiency and quality of water well drilling. Therefore, in the selection process, we should pay attention to the selection and use of lower bit. When we are operating the drill bit, we must pay attention to several aspects in order to better production and operation.
1. After the drilling structure of the drill bit of the water well drilling rig is drilled, the central drilling tool needs to be replaced in time. First, the hole bottom needs to be cleaned, and then the residue at the hole bottom needs to be blown away. After the drill bit stops rotating, the drilling tool in the water well drilling rig can be lifted up slowly. When the lifting force is just enough to lift the drilling tool, it is the most appropriate.
2. During the drilling process, the drill bit of the water well drilling rig shall be summarized. It is also necessary to carefully observe the follow-up situation of the casing, timely understand the specific situation in the hole, and keep the hole clean when necessary. Moreover, the drill bit in the water well drilling rig shall not be pulled out by force during the drilling process.
3. Sometimes there will be more residual rock slag at the bottom of the hole of the water well drilling rig, and the rotating part of the eccentric bit will be stuck by the rock slag, which will affect its retraction and production. At this time, it is necessary to transport air pressure, clean the hole again, make the DTH hammer work in a short time, and then lift the central drilling tool again.
Our machines can be applied to various countries in the world, suitable for various scenarios, various geological scenarios including deserts, swamps, grasslands, mountains, orchards, etc.especially suitable for water intaking in moutainnous area and rock layer. The drill adopts newest hydraulic technology, mating with big torque hydraulic motor rotation and large bore hydraulic oil cylinder driven, lower the labor, cut down assist time, improve efficiency of construction and project quality.
