Drilling platform is the core equipment for drilling oil fields. Its normal operation and work efficiency are directly related to the economic construction and growth rate of oil wells. Due to the particularity of the drilling technology, the requirements for the electric control equipment of the drilling rig are particularly strict, and the selection of the frequency converter is very cautious. It has long been the world of imported products. Due to the high price of foreign frequency converters, long debugging cycle, and long maintenance cycle, the frequency converter failures are often not repaired in time, and quality accidents often occur. In this context, our CV3300 high-performance vector inverter, with its excellent technology, convenient debugging and maintenance, high efficiency, and stable performance, has been favored by users and has been successfully applied on a Chinese petroleum drilling platform in Xinjiang.
2. Advantages of easy drive CV3300 series inverters in oilfield drilling platform application equipment
Compared with traditional mechanical drives, frequency converter-driven drilling turntables have the following characteristics: energy saving, simple operation, stepless speed regulation, high control accuracy, and high work efficiency. The development and application of frequency conversion technology on oilfield drilling rigs has not only improved the level of drilling rigs, but also improved It improves the operating performance of the drilling rig, and more importantly, it strengthens the operating capability of the drilling rig, and improves the efficiency and quality of drilling.
3. Features of Yidrive CV3300 series inverter
Easydrive CV3300 series inverter is a general high-performance open-loop vector inverter with advanced control performance such as large low-frequency torque, self-identification of motor parameters, optimal acceleration and deceleration control, and wave-by-wave current limiting; powerful I/O expansion Functions, support a variety of communication control cards, can customize process control cards and other extended functions for customers; have functions that meet different process requirements, such as swing frequency control, multi-segment control, simple PLC control and other practical functions. It can be used to drive automation products such as machine tools, cables, textiles, food, chemicals, etc., to meet the performance and function requirements of different industrial equipment.

After this frequency conversion system upgrade, several obvious problems in the previous control system have been solved: 1. The driller can only adjust the turntable speed and drilling pressure by constantly changing gears, and then change the drilling speed, resulting in low work efficiency. . 2. The motor needs to be started several times each time the gear is shifted. Excessive starting current will be generated during the starting process, which will impact the power grid and other equipment. Sometimes the starting current is extremely large, causing other equipment to fail to work normally. 3. When working at low speed, the low speed control requirement can only be achieved by changing the low gear, and at the same time the motor is in the power frequency operation state, which wastes a lot of electric energy. Customers are very satisfied with the effect of using the machine, and have created a good influence and reputation in the industry.
