摘要

分析了原料磨液压缸密封漏油、活塞杆断裂的原因，同一磨辊下，两个液压缸活塞杆受力不均，造成液压缸活塞杆疲劳断裂。在更换液压缸过程中，特别制作了一种新型简易辅助工具，可有效调整缸杆端与耳环端面间隙，确保了同一磨辊下两个液压缸活塞杆受力相同。更换液压缸后，通过控制石灰石粒度、磨机产量及料床厚度，加强磨机液压系统的维护，彻底解决了液压缸密封及活塞杆断裂问题。

Abstract:

It analyzed reasons of the oil leakage of raw mill sealing and cylinder piston head cracking. Under one mill roller, two cylinder piston rod bear different pressure, which caused cylinder fatigued cracking. While replacing hydraulic cylinder，one new simple installing tool was made to adjust the edge between piston rod and clevis end, which insures the same pressure bear by two piston rod of hydraulic cylinder. After replacing hydraulic cylinder, by controlling limestone grain size, the mill output and suitable raw material thicknesses, and strengthening maintenance of mill hydraulic system，hydraulic cylinder cracking problem has been solved completely.

Key words: raw mill hydraulic cylinder piston rod mill roller fatigued cracking
