The transportation of high-temperature medium places bigger requirements around the structure, materials and auxiliary system from the pump. Let us talk about the cooling prerequisites of various temperature improvements and the corporate's applicable pump sort:
1. For media with a temperature lessen than a hundred and 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 really should exceed H grade when over ninety°C); and DFCZ frequent type and IH chemical pump can use temperature to undertake suspension construction The higher limit is a hundred and forty°C ~ one hundred sixty°C; IHF lining fluorine pump may be used as much as two hundred°C; only CQB regular magnetic pump use temperature does not 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 one hundred twenty°C and down below 300°C, a cooling chamber shall be furnished around the pump deal with. The sealing chamber shall also be connected to the coolant (with double mechanical seal), in the event the coolant isn't permitted to penetrate into the medium. It should be taken just after cooling its personal medium (is often realized by straightforward warmth exchanger).
three. For high temperature medium previously mentioned three hundred°C, not only the pump head portion really should be cooled, but additionally the more info suspension bearing chamber really should be Geared up having a cooling process. The pump composition is generally in the form of a central guidance. The mechanical seal is if possible a metal bellows kind, but the value is superior ( The value is much more than ten occasions that of a normal device seal).
