The transportation of high-temperature medium places greater needs within the construction, components and auxiliary program in the pump. Let's talk about the cooling prerequisites of various temperature alterations and the corporate's applicable pump kind:
one. For media that has a temperature decreased than one hundred twenty°C, there is normally no Unique cooling system, as well as medium by itself is used for lubrication and cooling. Such as DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (defense amount of shielded motor ought to exceed H quality when in excess of 90°C); and DFCZ popular variety and IH chemical pump can use temperature to adopt suspension composition The upper Restrict is one hundred forty°C ~ a hundred and sixty°C; IHF lining fluorine pump may be used as much as two hundred°C; only CQB regular magnetic pump use temperature does not exceed one hundred°C. It's truly worth mentioning the medium that is easy to crystallize or has particles more info ought to be Geared up using a sealing area flushing line (created having an interface).
2. For mediums higher than 120°C and underneath 300°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 just after cooling its very own medium (is usually 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, and also the suspension bearing chamber ought to be Outfitted that has a cooling system. The pump construction is usually in the shape of the central aid. The mechanical seal is preferably a metal bellows sort, but the cost is superior ( The price is over 10 moments that of a traditional equipment seal).
