本刊前几年分别发表过有关铁牛-55型拖拉机缸套、机体穴蚀的文章,文章虽短,但很有价值。但在乡镇农机修理厂,因设备有限,有些难以解决。我厂解决此问题采用下述方法。分析:铁牛-55型拖拉机,电起动的比汽油机起动的穴蚀多而严重。其机体进水道在缸套上部,缸套冷却水70%不能得到强制循环,只靠对流,缸套部分产生大量气泡。气泡破裂产生幅射波,增加了穴蚀的
A few years ago published articles about the tractor liner tractor -55, body cavitation articles, the article is short, but very valuable. However, in the township farm machinery repair shop, due to equipment is limited, some difficult to solve. I plant to solve this problem using the following method. Analysis: Tractor -55 tractor, electric start more than the gasoline engine pitting and more serious. Its body into the water channel in the upper cylinder, cylinder cooling water 70% can not be forced to cycle, only by convection, cylinder liner part of a large number of bubbles. Bubble rupture produces radiation waves, an increase of cavitation
