砂型干燥炉台车,是干煤炉的重要组成部分。台车要在400～500℃条件下工作,所以,对台车的结构应给予足够重视。台车结构,常见的有轴承式和滚动式等形式(图1、2)。轴承式台车具有稳定性好的优点,但其缺点是,台车在炉内受热,引起构件涨缩变形,造成车轮运转不灵,且因轴承润滑困难,牵引动力大。滚动式台车,运动阻力比较小,维修方便,但其稳定性差,极易翻车,而且轨道上要铺放较多的滚轮。
Sand drying furnace trolley, is an important part of the dry coal stove. Trolley to 400 ~ 500 ℃ under the conditions of work, so the structure of the trolley should be given sufficient attention. Trolley structure, a common form of bearing and rolling (Figure 1,2). Bearing trolley has the advantages of good stability, but its disadvantage is that the trolley is heated in the furnace, causing the components to expand and deform, causing the wheel to run ineffective, and due to bearing lubrication difficulties, the traction power is large. Rolling trolley, exercise resistance is relatively small, easy maintenance, but its stability is poor, easy to overturn, and the track to be laid more rollers.
