The transportation of large-temperature medium puts larger demands about the framework, resources and auxiliary technique 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 Specific cooling program, and also the medium alone is employed for lubrication and cooling. Including DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (protection volume of shielded motor need to exceed H grade when around ninety°C); and DFCZ typical style and IH chemical pump can use temperature to undertake suspension structure The higher limit is a hundred and forty°C ~ one hundred sixty°C; IHF lining fluorine pump can be employed approximately 200°C; only read more 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 need to be Outfitted which has a sealing surface area flushing line (designed using an interface).
two. For mediums previously mentioned a hundred and twenty°C and beneath three hundred°C, a cooling chamber shall be supplied to the pump include. The sealing chamber shall even be linked to the coolant (with double mechanical seal), when the coolant will not be allowed to penetrate to the medium. It ought to be taken following cooling its possess medium (can be recognized by uncomplicated heat exchanger).
3. For prime temperature medium higher than 300°C, not merely the pump head aspect must be cooled, but in addition the suspension bearing chamber need to be equipped using a cooling process. The pump structure is usually in the shape of the central support. The mechanical seal is preferably a steel bellows variety, but the worth is superior ( The price is over 10 periods that of a traditional equipment seal).
