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 variations and the corporation's relevant pump variety:
1. For media having a temperature lower than a hundred and twenty°C, there is frequently no Particular cooling program, and also the medium alone is employed 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 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 ~ 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 here particles need to be equipped which has a sealing surface area flushing line (built using an interface).
two. For mediums over 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), when the coolant is just not permitted to penetrate in to the medium. It ought to be taken after cooling its very own medium (is usually realized by basic warmth exchanger).
3. For high temperature medium earlier mentioned three hundred°C, not just the pump head portion really should be cooled, but additionally the suspension bearing chamber really should be Geared up having a cooling technique. The pump composition is generally in the form of a central assist. The mechanical seal is if possible a metallic bellows type, but the value is substantial ( The cost is much more than 10 instances that of a standard device seal).
