May I ask if a damper is needed for the vulcanizing agent pump?
Thread Content
For wet vulcanization, the vulcanizing agent pump has a capacity of 2.1 m3/h and an outlet pressure of 0.6; the secondary pump is a metering pump. Is it generally necessary to install a damper? Thank you all
Catalyst sulfidation doesn’t have such strict requirements for flow stability, so it should be fine without a damper.
Adding dampers should give better results! ! ! ! ! ! !
Personally, I don’t think it’s necessary to add one; we’ve used gear pumps before, as well as metering pumps, and the flow rate requirements for this aren’t that strict
We don’t add it here; the amount of sulfurization is more or less that amount, and there’s no need for excessive precision
There’s no need for excessive precision; there are always some fluctuations in the material flow rate. As long as the overall sulfur content remains within acceptable limits, that’s fine. We use metering pumps without dampeners
A buffer must be installed for a metering pump with such high flow rates. The main purpose of using a buffer is to reduce vibrations in the pipes; these metering pumps generate significant pulsations, and without a buffer, the pipe supports could be damaged by those vibrations. Add it; it’s not much money.
There is no damper at the outlet of the vulcanizing agent pump in our unit
