The transportation of significant-temperature medium places bigger requirements on the structure, materials and auxiliary system of your pump. Let us look at the cooling demands of different temperature adjustments and the organization's applicable pump style:
one. For media by using a temperature reduced than 120°C, there is usually no Distinctive cooling technique, as well as the medium itself is useful for lubrication and cooling. For example DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (safety level of shielded motor should really exceed H grade when more than ninety°C); and DFCZ frequent kind and IH chemical pump can use temperature to undertake suspension construction The higher limit is a hundred and forty°C ~ one hundred sixty°C; IHF lining fluorine pump can be website used nearly 200°C; only CQB everyday magnetic pump use temperature isn't going to exceed 100°C. It can be well worth mentioning the medium that is straightforward to crystallize or includes particles should be Outfitted having a sealing floor flushing line (developed by having an interface).
2. For mediums previously mentioned 120°C and under three hundred°C, a cooling chamber shall be offered over the pump go over. The sealing chamber shall even be linked to the coolant (with double mechanical seal), once the coolant is not really allowed to penetrate to the medium. It ought to be taken following cooling its individual medium (may be recognized by very simple heat exchanger).
3. For prime temperature medium higher than 300°C, not merely the pump head section must be cooled, and also the suspension bearing chamber should be equipped by using a cooling procedure. The pump structure is usually in the form of a central guidance. The mechanical seal is if possible a metal bellows kind, but the value is significant ( The worth is more than 10 instances that of a standard device seal).
