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 changes and the corporation's relevant pump form:
1. For media having a temperature lower than a hundred and twenty°C, there is frequently 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 really should exceed H grade when over ninety°C); and DFCZ typical type 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 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 by having an interface).
2. For mediums previously mentioned a hundred and twenty°C and under three hundred°C, a cooling chamber shall be offered over website 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 in the medium. It ought to be taken right after cooling its have medium (may be recognized by simple heat exchanger).
3. For top temperature medium above 300°C, not simply the pump head part has to be cooled, and also the suspension bearing chamber should be Outfitted that has a cooling system. The pump structure is usually in the shape of the central aid. The mechanical seal is preferably a metal bellows sort, but the cost is superior ( The worth is a lot more than ten occasions that of a standard device seal).
