The transportation of significant-temperature medium puts increased necessities to the framework, elements and auxiliary process on the pump. Let's speak about the cooling specifications of different temperature changes and the company's relevant pump variety:
1. For media having a temperature lower than a hundred and twenty°C, there is frequently no Specific cooling program, and also the medium alone is utilized for lubrication and cooling. Including DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (protection volume of shielded motor need to exceed H grade when around ninety°C); and DFCZ typical style and IH chemical pump can use temperature to undertake suspension structure The higher limit is a hundred and forty°C ~ one hundred sixty°C; IHF lining fluorine pump can be used as many as 200°C; only CQB everyday magnetic pump use temperature isn't going to exceed 100°C. It can be well worth mentioning which the medium that is not difficult to crystallize or consists of particles need to be equipped which has a sealing surface area flushing line (built using an interface).
two. For mediums previously mentioned a hundred and twenty°C and beneath three hundred°C, a cooling chamber shall be supplied to the pump include. The sealing chamber shall even be linked to the coolant (with double mechanical seal), once the coolant will not be allowed to penetrate to the medium. It ought to be taken following cooling its individual medium (can be recognized by here uncomplicated heat exchanger).
3. For prime temperature medium higher than 300°C, not merely the pump head section has to be cooled, and also the suspension bearing chamber should be equipped by using a cooling procedure. The pump structure 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 periods that of a traditional equipment seal).
