How to calculate the total compression amount of the plate bundle in a plate heat exchanger?
To calculate the total compression amount of a plate heat exchanger’s plate bundle, this value is the difference between the length of the plate bundle before the bolts are tightened and its length after tightening, expressed as a ratio to the length of the bundle before tightening. The calculation formula is: Ф = (L1 + L2) / L1 * 100%. Here, Ф represents the total compression amount of the plate bundle； L1 – Length of the plate bundle before tightening, in mm. L2 – Length of the plate bundle after tightening, in mm. The total compression of the plate bundle should generally be kept within 20%.
Plate corrugation depth + plate thickness; actual values required. Then multiply by the number of plates.
