ST 180 Crawler Mounted Drilling Rig Working Process
After starting the engine, run it at low speed for 3-5 minutes, and turn the power head under no-load, so as to facilitate the normal operation of the hydraulic system.
2. During the operation of the drilling rig, the operator shall often observe whether the indications of various instruments are normal, and stop in time for inspection in case of any abnormality.
3. During operation, special attention shall be paid to the operation control handle in place to avoid pressure impact on the system.
4. During use, check and fasten the pipe joints with pressure vibration and the fastening bolts of the oil pump to ensure that there is no oil and air leakage.
5. The drilling rig must be commanded by a specially assigned person when walking, and special attention shall be paid to dangerous sections such as high-voltage line and puddle.
6. No one is allowed to stand within the rotating range of the drilling rig.
7. After the drilling rig is transferred, the crawler must be extended immediately after getting off the flatbed truck.
8. When checking the hydraulic oil, wait until the hydraulic oil cools down.
Five experiences in finding water from large wells in Qingshi Mountain area:
1, The groundwater level of thick limestone is generally deep, and when the water level is shallow, fractured zones and fault zones can be found.
2, Thick marl is generally not easy to drill a well, and a well with good water volume can be found when the supply conditions are good due to severe weathering and fragmentation.
3, The dolomitic gray layer is better in areas with longer seasonal spring periods and is generally not easy to drill wells.
4, When the supply conditions of limestone mixed with shale are very certain, the conditions are better.
5, In general, in the case of engineering drilling rigs, the water level in the limestone formation is not high enough to reach the area, which means that there is generally not enough water pump to continuously pump water.
