The transportation of large-temperature medium puts greater needs about the construction, components and auxiliary program in 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 widespread sort and IH chemical pump can use temperature to undertake suspension framework The upper Restrict is 140°C ~ a hundred and sixty°C; IHF lining fluorine pump can be utilized nearly two hundred°C; only CQB ordinary magnetic pump use temperature won't exceed one hundred°C. It is actually value mentioning that the medium that is a snap to crystallize or includes particles should be Outfitted with a sealing floor flushing line (designed using an interface).
two. For mediums previously mentioned one hundred twenty°C and below 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 just isn't permitted to penetrate into the medium. It ought to be taken just after cooling its here very own medium (is often realized by basic warmth exchanger).
three. For high temperature medium previously 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 form of a central help. The mechanical seal is ideally a steel bellows style, but the price is higher ( The value is in excess of ten times that of a normal machine seal).
