As of November 9, Zhenhai Refining & Chemical first permanent magnet speed regulating device safe operation of more than 2000 days, the cumulative energy-saving 2.06 million kilowatts, equivalent to 670,000 kilograms of standard coal, energy-saving effect is very obvious.
Permanent magnet speed control device is a new technology in the field of energy saving in recent years, the technology is in the motor and driven fan, pump equipment installed between a permanent magnet speed control device, by adjusting the permanent magnet device to achieve load speed adjustment , So as to achieve energy-saving goals.This technology compared with the traditional frequency control with simple structure, high reliability, adapt to harsh environments, small amount of routine maintenance, long service life and other characteristics of this technology has also been included in the National Development and Reform Commission 2014 edition of the national key energy-saving low-carbon technology promotion directory (energy-saving part).
Zhenhai Refining and Electrical Department for the first time in 2012, the technology used in the oil refinery No. 1 Cooling Water Tower No. 31 fan, but also the Sinopec system using the same type of permanent magnet speed control device one of the earliest enterprises. Digestion and application of work, prepared a detailed instructions for operation and maintenance, combined with the use of the scene constantly improve the routine inspection and regular maintenance requirements, but also within the company-wide application of such energy-saving technologies, and achieved remarkable results, and upgrading of the old refinery In the promotion project, it is actively promoted and applied to achieve the goal of saving energy and reducing the overall cost of equipment life cycle.
