The transportation of large-temperature medium puts increased necessities to the framework, elements and auxiliary process on the pump. Let's speak about the cooling needs of different temperature changes and the company's relevant pump form:
1. For media having a temperature reduce than a hundred and twenty°C, there will likely be no Exclusive cooling technique, as well as the medium itself is useful for lubrication and cooling. For example DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (safety level of shielded motor should really exceed H grade when more than ninety°C); and DFCZ widespread kind and IH chemical pump can use temperature to undertake suspension construction The upper Restrict is 140°C ~ a hundred and sixty°C; IHF lining fluorine pump can be utilized around two hundred°C; only CQB common magnetic pump use temperature doesn't exceed a hundred°C. It really is worth mentioning the medium that is simple to crystallize or incorporates particles must be equipped by using a sealing surface flushing line (made with an interface).
two. For mediums above one hundred twenty°C and down below 300°C, a cooling chamber shall be delivered within check here the pump address. The sealing chamber shall also be linked to the coolant (with double mechanical seal), in the event the coolant just isn't permitted to penetrate into the medium. It should be taken just after cooling its very own medium (is often realized by basic warmth exchanger).
three. For high temperature medium earlier mentioned three hundred°C, not just the pump head portion needs to be cooled, but additionally the suspension bearing chamber really should be Geared up having a cooling process. The pump composition is generally in the form of a central assist. The mechanical seal is if possible a metallic bellows kind, but the value is substantial ( The worth is more than 10 instances that of a traditional machine seal).
