ST 200 Customized Crawler Mounted Drilling Rig
ST 200 Crawler Mounted Drill Rig Product Description
The drilling rig is a highly efficient and versatile drilling rig that is mainly used to drill wells, agricultural irrigation wells, ground heat pump wells and other wells. It is especially suitable for water intake projects in mountainous and rock formations.. The new hydraulic rig technology, supporting high hydraulic torque and a large rotating hydraulic propulsion diameter. Centralized control of the hydraulic console for easy operation. This series of platforms uses excavator crawler chassis for off-road performance.

What 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.
