The transportation of large-temperature medium puts larger demands to the framework, elements and auxiliary process with the pump. Let us speak about the cooling needs of different temperature modifications and the company's relevant pump form:
one. For media using a temperature decreased 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 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 may be used around two hundred°C; only CQB common magnetic pump use temperature does not exceed one hundred°C. It's truly worth mentioning the medium that is easy to here crystallize or has particles ought to be Geared up having a sealing area flushing line (developed having an interface).
2. For mediums earlier mentioned 120°C and underneath three hundred°C, a cooling chamber shall be offered over the pump go over. The sealing chamber shall even be connected to the coolant (with double mechanical seal), once the coolant is not really allowed to penetrate to the medium. It ought to be taken right after cooling its individual medium (may be recognized by very simple heat exchanger).
3. For prime temperature medium higher than 300°C, not merely the pump head section must be cooled, but in addition the suspension bearing chamber need to be equipped using a cooling process. The pump structure is generally in the form of a central guidance. The mechanical seal is if possible a metallic bellows kind, but the value is substantial ( The worth is more than 10 occasions that of a standard device seal).
