The transportation of large-temperature medium places greater prerequisites within the composition, elements and auxiliary method with the pump. Let's mention the cooling requirements of different temperature variations and the business's relevant pump type:
1. For media that has a temperature reduce than one hundred twenty°C, there will likely be no Particular cooling process, and the medium by itself is employed for lubrication and cooling. Which include DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (defense level of shielded motor must exceed H quality when around 90°C); and DFCZ frequent variety and IH chemical pump can use temperature to undertake suspension structure The upper limit is one hundred forty°C ~ a hundred and sixty°C; IHF lining fluorine pump can be employed as much as 200°C; only CQB common magnetic pump use temperature won't exceed a hundred°C. It's well worth mentioning the medium that is a snap to crystallize or contains particles ought to be Outfitted by using a sealing floor flushing line (intended having an interface).
two. here For mediums above 120°C and below 300°C, a cooling chamber shall be supplied within the pump protect. The sealing chamber shall even be linked to the coolant (with double mechanical seal), if the coolant will not be permitted to penetrate in the medium. It ought to be taken immediately after cooling its individual medium (is usually understood by very simple warmth exchanger).
three. For top temperature medium earlier mentioned three hundred°C, not simply the pump head portion should be cooled, and also the suspension bearing chamber really should be Outfitted by using a cooling technique. The pump construction is usually in the form of a central aid. The mechanical seal is if possible a metallic bellows variety, but the cost is large ( The value is greater than 10 situations that of a traditional device seal).
