GK 200 Core Drilling Rig Main Advantages:
1. The drill adopts mechanical transmission, with simple structure and easy maintenance and operation.
2. The drilling rig is equipped with water brake device, which can control the tripping speed, reduce the wear of drum, brake belt and other parts, the impact force of lifting and tripping.
3. Technical improvement is made on the original drilling rig. The shaft diameter device is added in the clutch part to enhance the power of the driving shaft, and the gear in the gearbox of the drilling rig is also improved in material and technology on the original basis.
4. It is applicable to deep hole drilling projects such as coalfield geology, hydrogeology, metal deposits, non-metal deposits and natural gas, with strong practicability, operability and universality. It can meet the process requirements of diamond drilling, cemented carbide drilling
5. Motor or diesel engine for users to choose according to the operating environment or conditions.
GK 200 Core Drilling Rig Main Application:
(1) general survey exploration and, geo-exploration, road and building exploration, shothole drill
(2) Selects different drill bit of diamond, alloy or steel grit according to the stratum.
(3) Drills in loams and base rock layers of two to nine grades.
The important role of bits 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.
