Rotary table is one of the important supporting equipment in petroleum cobalt repair operations, which is an important component for rotating and carrying drill string. During normal drilling, drive the drilling tool to rotate: when lifting or lowering the casing, support the weight of all drill string or casing string in the well; Complete auxiliary tasks such as reverse locking and insertion when performing disassembly, drill bit disassembly, and accident handling; When drilling with downhole power drilling tools, it is used to brake the upper drill string.
Rotary Table features:
1. Both the large and small gears are made of alloy steel material.
2. The overall main core is a cast steel component.
3. The pin transmission type can be fitted with roller bushings for API standard square or hexagonal drill rods, and can be used for both long and short slips.
4. The turntable has sufficient lubrication and reliable sealing.
