In the petrochemical industry landscape of Southeast Asia, Thailand holds a pivotal position. Ethylene, as the fundamental raw material in the petrochemical industry, can be found extensively in the production processes of various petrochemical products such as plastics and synthetic rubber. In recent years, the domestic plastic products, automobiles, electronics and other industries in Thailand have been booming, significantly boosting the domestic demand for ethylene. At the same time, neighboring manufacturing countries such as Vietnam and Indonesia, which have rapidly risen, have opened up vast export markets for Thai ethylene, keeping the market demand for Thai ethylene at a consistently high level.
The TPI Group of Thailand is a leading enterprise in the industrial sector of Thailand. With its outstanding R&D capabilities, it has joined the ranks of a few enterprises worldwide that possess proprietary production technologies for EVA. It has gained a prominent reputation on the international chemical stage. Facing such a major industry player, the overseas sales team of Wolong demonstrated extraordinary perseverance and professionalism. After more than two years of continuous tracking, Wolong established a professional team covering sales, technology, and management, and conducted multiple in-depth exchanges with the TPI Group. Through multiple rounds of rigorous and in-depth technical discussions, the Wolong team accurately grasped the strict requirements of TPI Group's EVA production equipment and successfully won the bid for the explosion-proof motor project of the primary and secondary machines of the EVA production line of the TPI Group.
The explosion-proof motors used in the project will work in conjunction with the Buchhalter compressor. Through multiple stages of compression, the ethylene gas will be gradually pressurized to the high-pressure conditions required for EVA production. The compressor unit adopted in this project is a horizontal opposed reciprocating six-stage eight-row structure, driven by a single-bearing-supported motor. This design not only places extremely high demands on the operational stability and reliability of the motor, but also tests the manufacturing process of the motor.
The 6.8MW-32P explosion-proof synchronous machine provided by Wolong is not only the result of Wolong Electric Drive's Nanyang Explosion-proof Group's first involvement in the EVA mainframe supporting project, but also an important breakthrough for the direct export of domestic explosion-proof motors. This achievement marks that China's domestic explosion-proof motors have successfully entered the core industrial chain of high-end chemical equipment in Southeast Asia, breaking the long-term technological monopoly of foreign enterprises in this field. This success not only accumulated valuable project experience for Wolong Electric Drive, but also laid a solid foundation for the further expansion of domestic motors in the global EVA project market.
