The transportation of high-temperature medium places higher specifications within the construction, supplies and auxiliary method from the pump. Let's take a look at the cooling prerequisites of various temperature alterations and the corporate's applicable pump kind:
1. For media which has a temperature decreased than one hundred twenty°C, there is normally no Unique cooling system, as well as medium alone is utilized for lubrication and cooling. Like DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (security standard of shielded motor must exceed H grade when about 90°C); and DFCZ common form and IH chemical pump can use temperature to adopt suspension structure The upper Restrict is one hundred forty°C ~ 160°C; IHF lining fluorine pump can be employed 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 below 300°C, a cooling chamber shall be delivered within the pump address. The sealing chamber shall also be connected 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 here immediately after cooling its personal medium (is often understood by straightforward warmth exchanger).
three. For high temperature medium previously mentioned three hundred°C, not only the pump head element 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 metallic bellows sort, but the cost is high ( The price is over ten periods that of a traditional equipment seal).
