The transportation of substantial-temperature medium puts increased necessities over the composition, supplies and auxiliary method in the pump. Let's talk about the cooling requirements of various temperature improvements and the corporation's relevant pump sort:
1. For media with a temperature lessen than a hundred and twenty°C, there is often no Particular cooling method, and the medium alone is employed for lubrication and cooling. Like DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (protection volume of shielded motor need to exceed H grade when around 90°C); and DFCZ typical style and IH chemical pump can use temperature to adopt suspension structure The higher limit is a hundred and forty°C ~ 160°C; IHF lining fluorine pump can be employed approximately 200°C; only CQB standard magnetic pump use temperature will not exceed a hundred°C. It truly is really worth mentioning which the medium that is straightforward to crystallize or contains particles must be equipped that has a sealing surface area flushing line (built using an interface).
two. For mediums over get more info a hundred and twenty°C and beneath three hundred°C, a cooling chamber shall be supplied to the pump include. The sealing chamber shall also be linked to the coolant (with double mechanical seal), when the coolant is just not permitted to penetrate in to the medium. It ought to be taken after cooling its possess medium (is usually realized by uncomplicated warmth exchanger).
3. For prime temperature medium earlier mentioned three hundred°C, not just the pump head aspect needs to be cooled, but in addition the suspension bearing chamber really should be Geared up having a cooling technique. The pump composition is usually in the shape of the central aid. The mechanical seal is preferably a metal bellows sort, but the cost is superior ( The price is over 10 moments that of a traditional equipment seal).
