变频技术在港口作业中的应用 摘要 如今，世界的经济全球化，贸易也随之全球化。我国从1978年改革开放至今，对外贸易也逐年增长，近年来更是突飞猛进。 以上海港为例：集装箱吞吐量从1978年9月的中国大陆港口“第一箱”，到2003年突破1000万标准箱、2006年突破2000万标准箱，再到2010年10月历史性的超过新加坡港，首次成为世界集装箱第一大港。散货同样如此：在很久之前的上海，码头上运煤是靠人力背麻袋的形式一点、一点的运，到如今带式输送机全电气化，自动化。短短的三十年时间，码头上早已没有往日的人声嘈杂，没有了“码头号子”，没有了划一的口号和整齐的步伐。 如今的港区是机械化、电气化作业。而在这作业方式转变的过程中，我们体会到机械化、电气化给予我们带来的方便、快捷、高效，但同时我们也不能回避遇到的问题。有时，换一种能源可以节约更多的财力；同样完成一项工作，不同的作业方式在节能上却有着千差万别。这些问题往往很少能有人注意到，但这些节能、降耗所能体现出的价值对于一个公司来说是何等的重要啊。本篇论文将围绕这两条主线进行深入研究和探讨，以实例阐明论点。为今后港区良好、可持续发展提供借鉴。 关键词： 变频，轮胎式集装箱起重机，带式输送机，节能 ABSTRACT With the economic globalization, counties are now doing trade globally. Since the implementation of the Reform and Opening-up Policy in 1978, China has done more foreign trade year by year, and the increase is even more in recent years. Take Shanghai Port as an example: In September 1978, container throughput capacity of Shanghai Port was listed as the first in China and the port was regarded as the “First Port” in China; by 2003, the container throughput capacity of Shanghai Port had surpassed 10 million TEU; by 2006, the capacity had exceeded 20 million TEU, and in October 2010, the capacity of the Shanghai port firstly surpassed that of the Singapore port to become the worlds largest container port. Long time ago, coal were moved by dockers package by package at dock in Shanghai. And nowadays, you will see electric and automatic belt conveyor everywhere at Shanghai’s modern port. After a short period of three decades, there has been no labor song and uniform pace any more. Our port today is mechanized and electrical. We are benefit from the convenience, quickness and efficiency of the transformation, but at the same time, we are faced with several problems. Energy consumption is one of them. When we complete a certain task, it will save the company a huge amount of energy if we change the energy source. However, few people recognize the problem. This assay will analyze these two main points with examples to provide a guidance of b
