The transportation of large-temperature medium puts greater specifications within the construction, resources and auxiliary process on the pump. Let's discuss the cooling specifications of different temperature variations and the corporation's applicable pump style:
one. For media that has a temperature decrease than one hundred twenty°C, there is generally no special cooling procedure, plus the medium by itself is utilized for lubrication and cooling. Including DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (protection level of shielded motor should really exceed H quality when more than ninety°C); and DFCZ widespread kind and IH chemical pump can use temperature to undertake suspension construction The higher limit is 140°C ~ one hundred sixty°C; IHF lining fluorine pump can be used nearly 200°C; only CQB normal magnetic pump use temperature does not exceed one hundred°C. It's really worth mentioning which the medium that is not hard to crystallize or has particles ought 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 furnished around the pump petrochemical process 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 should be taken soon after cooling its have medium (could be recognized by simple heat exchanger).
3. For top temperature medium above 300°C, not merely the pump head section must be cooled, and also the suspension bearing chamber need to be equipped using a cooling process. The pump composition is generally in the form of a central assist. The mechanical seal is if possible a metallic bellows type, but the value is substantial ( The cost is much more than ten occasions that of a normal machine seal).
