Rig adopts double motor drive single shaft Ishift AC frequency conversion Drawworks, realize double stages stepless speed regulationelectric drive control system adopts Siemens PLC and AC frequency conversion technology, The whole rig control system adopts theredundant heat backup mode,compatible,fault-tolerant performance is good; Equipped with high pump pressure F -1600 triplex cylindermud pump,Supporting the integration of driller control room, drller in driller's control room can complete the main operation.
Feature：
1.Give fullplay to the advantage of advanced digital AC frequency conversion electric transmission, and uses the machine,electricity,liquid, gas, digital control integration design, improve the control accuracy, simplifies the structure of drilling rig.
2. Equipment on the floor is installed at low position and overall hoisted. Reducing the workload of aerial work, improve the security.
3.Electric transmission adopts vector frequency conversion drive system, realize the fully digital control operation, obligate interface forremote fault diagnosis expert system,can realize the collection of control parameters and diling parameters (signal), display, storage, printing, remote monitoring and management.
4.Realizing bit pressure, driling rate, pump pressure, pump capacity to large range, high precision effectively control and greatly improvedthe dilling process. Using the characteristics ofrequency conversion technology, make Drawworks hover at zero speed, changed thetraditional way of driller operation.
5.The operation control system using dual PLC redundancy design, improve the reliability of the system. 1600 high pressure mud pump canimprove dilling speed,ensures the bit reliable high-speed rotation,lengthen the service life of the drill bit, improve driling efficiency.
