Instruction Manual for New Hydraulic Drilling Rig
Thank you for choosing to use our hydraulic drilling rigs, and I hope you can give us better feedback.
. Installation and debugging
1. First check whether the drilling rig equipment and tools are in good condition.
2. First add 30-40 catties of hydraulic oil, gasoline engine should add 95 gasoline, gasoline engine oil should be replaced in time.
3. When lifting, do not lift the drilling rig too high, and it is forbidden to stand or work below.
4. Please read the instruction manual and perform the actual drilling work after the operation is proficient.
. Matters needing attention
1. During the actual drilling, first find the position of the wellhead, and level the position where the machine is placed to avoid shaking.
2 Stand up the folded part of the drilling rig and fasten the fixing point screws.
3. Connect one end of the high-pressure water pipe to the water inlet of the main engine, and the other end to the water outlet of the pump, and tighten it with iron wire.
4. Dig a reservoir next to the well drilling machine, put the water inlet of the pump directly in the pool, and use circulating water when working.
5. When drilling, the safety cover is opened, the drill bit and the drill pipe are connected to the main engine, and the wire rope is kept in a slack state. No matter whether each rod is drilled to the bottom, the main engine part falls to the bottom. When changing the rod, lift it up again and close the safety cover. Well, let the joint head be 5 cm above the safety cover, and rewind the wire at this position.
6. When drilling down two to three drill pipes, make sure whether the water pump is blocked by mud, and keep the water pump running smoothly, so as not to block the drill bit or the mud can not rush up, causing difficulty in lifting the rod.
7. During drilling, if it is necessary to rewind the wire, first stop the reversing switch to the middle position, and wait until the speed of the drilling rig stops before rewinding the wire.
8. In the process of transportation, it can be installed separately, be careful not to damage the parts, and not to be exposed to rain or water.
. Mastering the water layer
When the drilling rig is about to drill to the required depth, it should be noted that the water is washed with large grains of sand or mud, like water-white mud eggs, irregularly rounded and somewhat smooth, all of which are water layers. so far.
.Equipment maintenance
Whether the gear box of the drilling rig and the reduction box of the lifting rod are short of oil, every time the well is drilled and completed, the water pump, drill bit and joint head should be flushed, and the joint head, V-belt, wire rope, etc. should be checked frequently for damage or replaced in time. We are not responsible for any accident caused by improper operation, please use it carefully. Please contact us if you have any details.
