A CT450132 permanent magnetic coupler installed on a 132kW/1480rpm belt conveyor of the coal handling system for the 2×1,000,000 kW generating units in the Phase III Project of Huainan Pingwei Power Plant has successfully passed the 168-hour trial operation. The relevant experience is summarized as follows.

This paper focuses on introducing the application of permanent magnet transmission technology renovation for the inclined conveyor at Guixi Smelter of Jiangxi Copper Industry, and compares its operation with fluid couplings. The results show that the permanent magnet transmission technology renovation features high reliability, reduced vibration, lower operating noise, and adaptability to frequent start-stop operation.

Although disc-type and cylinder-type permanent magnet products both belong to permanent magnet speed regulation products, they are completely different in terms of application time, structure, safety, heat dissipation principle and heat dissipation effect. This paper conducts a comprehensive comparative analysis on permanent magnet speed regulators with disc-type and cylinder-type structures.

Both permanent magnet speed regulators and frequency converters are widely applied and relatively advanced technologies at present, both of which are used for equipment speed regulation. However, they differ in many aspects such as working principles, later operation and maintenance, and adaptability to the operating environment. A brief comparison is made as follows.

随着环境恶化、资源匮乏，节能减排已成为中国乃至世界各国政府工作重要内容之一，为此各国政府在节能减排相关技术的研发及产品的推广方面加大投资。根据我国的经济结构形式和高能耗产业的布局情况，工业领域的节能减排将是重中之重
