How do I calculate the force required to support a spring?
Thread Content
As shown in the diagram: after the modification for central drainage in the storage tank (the red-colored added components include a tee, a valve, and two flanges), how can we determine whether the supporting force provided by the spring supports is still sufficient? It turns out that the total weight of this set was 350 kg, while after the modification it became 500 kg.
It depends on how many years the jar has been in use and what its capacity is.
Check whether your current weight falls within the design range of the spring bracket; the specifications are indicated on the label. After installation, verify that the spring bracket does not exceed its maximum travel limit
1. It is unclear whether this section of piping has any other support points in addition to the spring supports. The following explanation is based on the assumption that all loads are supported by spring brackets. 2. If it are variable spring brackets, verify the load capacity of those brackets; if both the original loads and the loads after the modification fall within this range, the increased weight after the modification will cause the springs to compress more, thereby achieving a new state of force balance. It should be noted that if the piping system experiences high-temperature expansion deformation and the new compression amount is insufficient to compensate for this thermal expansion, the spring needs to be replaced. 3. If it is a constant-force spring, in theory, a spring bracket suitable for the new load is required. Otherwise, the spring bracket is pressed to its limit and can no longer compensate for displacement. 4. From the schematic diagram, it appears to be a variable spring; with a very small load, the spring stiffness is likely low. For example: According to the standards of the JBT8130 sample, the original load model could be TD30-10; after modification, the load model becomes TD30-11
