Recently, several 220KW high-performance inverters of QD200 series of Qirod Electric have been successfully applied to the coke oven project renovation of Jiangsu Tianyu Energy Chemical Group Co., Ltd. At present, the equipment has successfully completed the commissioning and trial operation, and is actively cooperating with the entire coke oven renovation project. Start production early.

This technical transformation project belongs to Guanmao Coking Co., Ltd., a subsidiary of Jiangsu Tianyu Energy Chemical Group Co., Ltd. Due to the early construction time, the original two TH3846D tamping coke ovens have been unable to meet the current production needs, and The original system has low degree of automation and high energy consumption. The frequency conversion system introduced this time is to control the newly added coke oven drum cooling Roots blower. In this project, our engineers made detailed technical exchanges with Party A and the design institute. Party A also recognized the successful cases of our company in the coking project and the technical performance of the equipment. It stands out among the manufacturers and wins the favor of customers.

The whole system after the transformation has high control accuracy, can automatically adjust the speed and pressure, avoid frequent use of mechanical valve adjustment, and obtain stable pressure while stabilizing the speed; in addition, the motor starts and adjusts the speed smoothly, and there is no start-up current impact, extending the fan. and other equipment, reduces the noise of the Roots blower at high speed, and also achieves good energy-saving effect, bringing indirect economic benefits to the enterprise.
