Selection Procedure of Variable Effort Springs:
- For can type springs the spring height should be kept minimum from stability point of view. If spring height is less the moment on spring will reduce and tilting of spring (Fig. 5) can be avoided or significantly minimized.
- The spring which has lower spring rate will have lower load variation.
- While designing the spring hanger the sustained sagging should be minimized within +/-1 mm so that original piping system is not strained much.
