工程机械经常在严寒、酷暑和风雪雨雾天气中作业,按一般的使用与管理办法往往造成机械运转不良,甚至造成故障和事故。我单位曾先后在渡口、重庆、武汉、上海等地施工。各种自然条件差异颇大:渡口干热;重庆雾多;武汉夏季闷热,冬季湿冷;上海地处长江口,风湿度大,平均相对湿度80%。在渡口攀钢建设中,发动机极易过热,增 Construction machinery is often operated in severe cold, intense heat and wind, snow, rain, and fog. The general use and management methods often cause machinery to malfunction and even cause malfunctions and accidents. Our company has successively constructed ferry, Chongqing, Wuhan, Shanghai and other places. Various natural conditions are quite different: ferry dry heat; Chongqing fog more; Wuhan summer hot, cold and wet in winter; Shanghai is located in the mouth of the Yangtze River, wind humidity, average relative humidity of 80%. During the construction of Panzhihua Iron and Steel Co., Ltd., the engine could easily overheat and increase.
