套管接箍生产设备中液压缸的机械锁定

Hydraulic Cylinder Mechanical Lock of Casing and Coupling Production line

介绍了从美国 PMC公司引进的套管接箍生产线中 V型座调整机构的液压缸机械锁定装置。指出 ,安装调试时 ,液压缸测试锁紧力要达到有效锁紧力的两倍左右 ;解锁压力要适当 ,不能偏低或偏高 ;使用时应做到锁定可靠、解锁可靠 ,保证机械锁和液压缸的使用寿命。

This article introduces the V type adjusting hydraulic cylinder mechanical lock equipment of casing and coupling production line which imported from PMC. USA. When the installation and adjusting,the measuring locking force of hydraulic cylinder shall meet 2 times of the locking force,the unlock force shall proper and not lower or higher. The lock shall be reliable and the unlock shall be reliable too so as to ensure the life of the mechanical lock equipment and hydraulic cylinder.
