High Efficiency DQ30 Top Drive Rig For Electricity And Liquid Machine
Combination of machine, electricity and liquid machine DQ30 top drive rig
Top drive drilling device is a new type of drilling device which is used to replace the traditional drilling equipment. It moves the power part of the drilling machine from the lower rotary table to the upper tap of the drilling machine and directly drives the rotary drilling of the drilling tool. It is a combination of machine, electricity and liquid. It is the leading technology and equipment in petroleum drilling nowadays. The advantages of the top drive device are:
Save time.
Reverse drilling to prevent sticking
Drilling eyes
Directional drilling or coring drilling efficiency is high.
Accurate torque
Save mud
Easy to disassemble
Internal blowout preventer function
Use conventional faucet parts
It can save 20% - 40% drilling time and ensure the safety of operation, especially in drilling deviated wells, horizontal wells and highly difficult directional wells.
The direct drive top drive developed by our company has a high safety factor of 3, which is superior to the design requirements stipulated in APl Spec 8C standard. It has a strong overload capacity during drilling operation.
Gearless transmission mechanism, driven by motor directly into the spindle, can provide higher torque noise, no gear fault, transmission of energy loss to reduce the building maintenance convenience.
The permanent magnet synchronous torque servo motor is used. The effective power is more than 90%.
The center of gravity of the whole structure of the top drive keeps the same, so that there is no friction between the top drive and the slideway due to the bias, and the service life of the pulley is increased. ,
The structure is simplified, the weight is reduced, the effective lifting of the swimming system is ensured, and the wear and tear of the steel wire rope, bearing and other parts are reduced.
