The transportation of high-temperature medium places bigger requirements around the structure, materials and auxiliary system of the pump. Let us take a look at the cooling prerequisites of various temperature alterations and the business's applicable pump type:
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 ninety°C); and DFCZ prevalent sort 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 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 into the medium. It should be taken just after cooling its very own medium (is often realized by straightforward warmth exchanger).
three. For high temperature medium previously mentioned three hundred°C, not only the pump head element ought to be cooled, but also the suspension bearing chamber must be Geared up with a cooling method. The pump framework is mostly in the shape read more of the central assistance. The mechanical seal is ideally a steel bellows kind, but the cost is significant ( The price is greater than 10 moments that of a traditional equipment seal).
