The transportation of high-temperature medium places bigger requirements on the structure, materials and auxiliary system of your pump. Let us look at the cooling necessities 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 process, along with the medium itself is useful for lubrication and cooling. For instance DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (safety degree of shielded motor should really exceed H quality when more than ninety°C); and DFCZ widespread kind and IH chemical pump can use temperature to undertake suspension construction The higher limit is 140°C ~ one hundred sixty°C; IHF lining fluorine pump can be utilized approximately 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 over a hundred and twenty°C and beneath three hundred°C, a cooling chamber shall be provided about the pump cover. 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 click here 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 need to be equipped using a cooling process. The pump composition is generally in the form of a central assist. The mechanical seal is if possible a metallic bellows kind, but the value is substantial ( The worth is over 10 periods that of a normal device seal).
