The transportation of high-temperature medium places higher requirements around the structure, materials and auxiliary system of the pump. Let us look at the cooling necessities of various temperature adjustments and the organization's applicable pump style:
one. For media by using a temperature reduced than a hundred and twenty°C, there is normally no Particular cooling method, and the medium alone is utilized for lubrication and cooling. Such as DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (security amount of shielded motor must exceed H quality when over ninety°C); and DFCZ frequent type 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 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 straightforward to crystallize or contains particles really should be equipped that has a sealing surface flushing line (intended with the interface).
two. For mediums above one hundred twenty°C and below 300°C, a cooling chamber shall be delivered within the pump address. The sealing chamber shall also be connected to the coolant (with double mechanical seal), in the event the coolant isn't permitted to mixed flow pump penetrate into the medium. It should be taken immediately after cooling its have medium (is often realized by basic warmth exchanger).
3. For high temperature medium earlier mentioned three hundred°C, not only the pump head portion really should be cooled, but additionally the suspension bearing chamber must be Geared up with a cooling program. The pump framework is normally in the shape of a central assistance. The mechanical seal is ideally a steel bellows form, but the price is higher ( The value is a lot more than ten situations that of a normal machine seal).
