8. Each hydraulic tubing is covered with a protective sleeve, so that the tubing life longer..
rods are all controlled by hydraulic pressure.
Precautions during operation of water well drilling rig:
1. Before drilling, the drilling rig shall be constructed in strict accordance with the hole location, orientation, angle and depth
2. Ensure that the drill pipe is not blocked, bent or cracked when installing it.
3. When clean water drilling is adopted, water supply is not allowed before spudding, and pressure drilling can only be carried out after the water returns. Sufficient flow shall be ensured, and dry drilling is not allowed. When there is much rock powder in the hole, water shall be increased to extend the pumping time, and drilling can only be stopped after the hole is effectively flushed.
4. During drilling, the distance shall be measured accurately. Generally, the drill pipe must be measured every 10m of drilling or when the drilling tool is changed, and the hole depth shall be verified and relevant records shall be made. 5. Check the gearbox, shaft sleeve, horizontal and vertical shaft gear, etc. for overheating and abnormal sound. If any problem is found, stop the machine immediately to find out the cause and deal with it in a timely manner. Don't leave the problem unsolved. As a result, mechanical damage is very fast and maintenance costs are high over the years.
