液袋式液压胀管在高压加热器制造中的应用

The Application of Hydraulic Expanding in the High-Pressure Heater Manufacturing

目前高加胀管的几种方法,着重介绍了液袋式胀管的结构和工作原理,并对液袋式胀管方法和“O”型圈胀管方法进行比较,得出液袋式胀管方法是最经济有效的结论。

This article introduces the several methods of hydraulic expanding in high - pressure heater currently, as well as the structure and the work principles of the liquid bag type hydraulic expanding. It also takes the comparison between the liquid bag type hydraulic expanding method and ＂O＂ type hydraulic expanding method, which proves the liquid bag type hydraulic expanding method is more economic.
