The transportation of large-temperature medium puts larger demands about the framework, resources and auxiliary technique on the pump. Let's discuss the cooling specifications of different temperature variations and the corporation's relevant pump variety:
1. For media with a temperature decrease 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 grade when about 90°C); and DFCZ common form and IH chemical pump can use temperature to adopt suspension composition 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 needs to be Geared up using a sealing area flushing line (made with an interface).
2. For mediums higher than 120°C and underneath 300°C, a cooling chamber shall be presented on the pump protect. The sealing chamber shall even be connected to the coolant (with double mechanical seal), if the coolant is not allowed to penetrate in the medium. It ought to be taken right after cooling its very own medium (is usually realized by basic warmth exchanger).
3. For high temperature medium previously mentioned three hundred°C, not only the pump head portion really should be cooled, but additionally the suspension bearing chamber must be Geared up with a get more info 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 a lot more than ten situations that of a traditional machine seal).
