Sealing of reaction vessels with stirring and vacuum function and ordinary crystallizers
Thread Content
After feeding the material into the reactor, it needs to be heated; negative pressure is used to remove some water before the reaction takes place. The reaction temperature is around 80°C, at atmospheric pressure, and stirring is required. Is a mechanical seal sufficient for sealing such a reactor? Will there be oil leakage? Is a packing seal and a mechanical seal needed? Is it easy to manufacture with double sealing? Also, for the crystallizer, it only has stirring; is dual sealing needed to prevent oil leakage? The pharmaceutical intermediates produced have low added value; so how is sealing handled in such cases? . I would appreciate some guidance from those with more experience, thank you

Can a mechanical seal alone be used for the sealing of such a reactor? Sure ； Will there be oil leakage? Is a packing seal and a mechanical seal needed? During normal usage, oil leakage is unlikely ； For safety reasons, an additional packing seal can also be used ； Is it easy to manufacture with double sealing? It’s not difficult. Also, for the crystallizer, it only has stirring; is dual sealing needed to prevent oil leakage? It can be used, or it can be left unused ； The pharmaceutical intermediates produced have low added value; so how is sealing handled in such cases? It has nothing to do with added value; it’s related to reliability ；
