The transportation of significant-temperature medium places bigger requirements around the structure, materials and auxiliary method of the pump. Let us take a look at the cooling prerequisites of various temperature alterations and the business's applicable pump kind:
one. For media that has a temperature decrease than one hundred twenty°C, there is generally no special cooling procedure, plus the medium by itself is used for lubrication and cooling. Which include DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (defense degree of shielded motor should exceed H quality when above 90°C); and DFCZ prevalent sort and IH chemical pump can use temperature to undertake suspension framework The upper Restrict is 140°C ~ one hundred sixty°C; IHF lining fluorine pump can be used nearly 200°C; only CQB ordinary magnetic pump use temperature won't exceed 100°C. It is actually well worth mentioning which the medium that is a snap to crystallize or consists of particles need to be Outfitted 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 very own medium (is usually 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 really should be Geared up having a cooling technique. The pump composition is more info normally in the form of a central help. The mechanical seal is ideally a metallic bellows style, but the price is large ( The cost is in excess of ten moments that of a traditional equipment seal).
