The transportation of higher-temperature medium puts greater needs about the construction, components and auxiliary program in the pump. Let's discuss the cooling requirements of various temperature improvements and the corporation's relevant pump sort:
1. For media with a temperature lessen than one hundred twenty°C, there is often no Particular cooling method, and the 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 quality when about 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 can be used nearly 200°C; only CQB ordinary magnetic pump use temperature won't exceed 100°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 click here a hundred and twenty°C and beneath three hundred°C, a cooling chamber shall be supplied to 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 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 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 shape of a central assistance. The mechanical seal is ideally a steel bellows form, but the worth is higher ( The value is in excess of ten situations that of a standard device seal).
