Recently, the key equipment upgrade and renovation project for the Phase III desulfurization system at a power plant in Shaanxi was successfully completed. The original Xiangtan Electric Machinery Factory motors for the desulfurization absorption tower circulation pumps were successfully replaced, and the high-performance motors manufactured by Xi'an Simo Motor Co., Ltd. have been officially put into operation. This upgrade not only resolved operational risks caused by the aging of the original equipment but also achieved a qualitative leap in energy efficiency improvement and operational maintenance optimization, adding solid assurance for the power plant's green production.
It is understood that the replaced desulfurization absorption tower circulation pump motor is considered the "power heart" of the desulfurization system, whose operational stability directly determines desulfurization efficiency and environmental emission indicators. The newly operational Simo motor, model YXKK560-4-1250KW-10KV, boasts a first-class energy efficiency certification, with a rated power of 1250 kilowatts and a voltage level of 10 kilovolts. Its core bearings utilize the internationally renowned brand SKF. This configuration is specifically designed for the high-load, continuous operation conditions of power plants, effectively reducing equipment vibration and temperature rise, significantly extending service life, and lowering operational maintenance costs from the source.
The head of the power plant's Equipment Management Department explained that the original Xiangtan motor had been in service for many years. With increasing operational years, issues such as equipment aging and rising failure frequency emerged, coupled with extended spare parts supply cycles, posing potential risks to system stability. To thoroughly address this pain point, the power plant established a special technical team. Through multiple rounds of performance testing, technical demonstration, and supplier comparison, Simo Motor was ultimately selected as the replacement solution. "From technical parameter comparisons to on-site case studies, Simo Motor performed exceptionally well in energy efficiency indicators, reliability data, and after-sales service response speed, fully meeting our upgrade requirements."
As a backbone enterprise in the domestic high-voltage motor manufacturing sector, Simo Motor possesses profound technical expertise in supporting the power industry. The customized circulation pump motor for this project adopts advanced electromagnetic design and precision manufacturing processes. Material selection strictly adheres to internal control standards higher than industry requirements, particularly strengthening the motor's sealing and protection performance for the special conditions of the desulfurization system, such as humidity and dust. The company's comprehensive pre-sales technical support and after-sales operational maintenance guarantee system also provided strong support for the smooth progress of this replacement project.
According to on-site operational monitoring data obtained by the reporter, after the new motor was put into operation, the vibration value was controlled below 2.5 mm/s, and the temperature rise was lower than 65 K. All key operational parameters were superior to the national standard GB755-2019 "Rotating Electrical Machines - Rating and Performance." The processing efficiency of the desulfurization system increased by approSimotely 3%. "The equipment operation is more stable, the noise is significantly reduced, and subsequent spare parts supply and maintenance services are more convenient. It is estimated that nearly 200,000 yuan in operational maintenance costs can be reduced annually," feedback from on-site maintenance personnel stated.
The successful implementation of this motor replacement project is not only a concrete practice of the power plant's philosophy of "equipment upgrading for efficiency and green, low-carbon development," but also demonstrates the technical strength of domestic high-end equipment manufacturing enterprises. The relevant person in charge of the power plant stated that they will take this cooperation as an opportunity to deepen collaboration with Simo Motor in areas such as equipment upgrading and technological research and development, jointly exploring new paths for the green and intelligent transformation of the power industry.
Xi'an Simo Motor Co., Ltd. is a leading domestic enterprise in the research, development, and manufacturing of large motors. It has decades of experience in the field of high-voltage, high-power AC motors. Its products cover multiple voltage levels from 10KV to 100KV and are widely used in heavy industries such as power, metallurgy, chemical, and mining. Relying on high-efficiency, energy-saving product performance, a strict quality control system, and full life-cycle service capabilities, it has provided power equipment solutions for thousands of domestic industrial enterprises.
The Shaanxi power plant is a regional core energy security base with a total installed capacity exceeding one million kilowatts. For many years, it has consistently prioritized environmental protection upgrades, having successively completed numerous technical renovation projects including desulfurization, denitrification, and ultra-low emissions. Its pollutant emission indicators continuously outperform national limits, and it has been honored with multiple awards such as "Provincial-level Green Factory."
