ST 180 Crawler Mounted Drilling Rig Features
1. The drilling rig hydraulic transmission of the rig effectively utilizes the power. This makes the overall power loss small and the drilling cost low.200m 300m 400m 500m 600m depth Truck crawler portable compressor DTH water well drilling rig
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.
