Product name: Electric drive drilling rigs
Place of origin: China
Features:
1. It has been designed to fit for well depth of 4,920~22,960ft (1500~7000m).
2. The manufacture of the main components is based on the related api specifications and the basic parameters are accorded to sy/t5609-1999 <
> and api specifications.
3. The technology of ac frequency conversion to control speed and the number control has been adopted to adjust the hoisting speed, rotation speed of the rotary table and stroke number of the slurry pump. Thus the performance of speed control of hoisting winch, rotary table, slurry pump and the ratio of the power utilization had been largely promoted.
4. The wholly moved parallelogram substructure (with various models) enables the equipments and derrick to be assembled at low level and to be lifted to the designated position by the draw works.
5. The main brake adopts the hydraulic plate type which provides the big moment of brake and is sensitive and reliable. The auxiliary brake is equipped with the electromagnetism eddying brake or eton brake.
6. The rotary table is driven by independent drive system or drawing through the chain.
7. Modular design, simple structure, convenient to disassembly and assembly departments.
