Engineering Drilling Rigs Features:
The Type 50 rig is a high, medium and low speed rig with hydraulic feed. Compared with other similar products, it has the advantages of light weight, simple structure, fast drilling speed, large diameter of coring sample, etc. It is the advanced portable hydraulic drilling machine in China. It is especially suitable for coring operations in mountainous areas, hills, rivers and other special difficult terrains, as well as engineering geological surveys for railways, hydropower, traffic, bridges, dam foundations, etc.; geological core drilling, physical exploration; small grouting holes, Drilling of blastholes; drilling of small wells.
Prevention method of drilling tool breaking of water well drilling rig
1. All pipes, joints and couplings shall be stored and used according to the new and old degree. Check the bending and wear of drilling tools by lifting and lowering drilling tools, correcting hole depth and relocation time.
2. It is forbidden to use a sledge hammer to knock the drill pipe and its joint when screwing and unloading the drilling tool.
3. When the rotary resistance is too large during reaming or drilling, it is not allowed to start the machine forcibly.
4. Master reasonable WOB, and do not blindly pressurize drilling.
