The transportation of high-temperature medium places higher specifications around the structure, supplies and auxiliary method of your pump. Let us look at the cooling necessities of various temperature adjustments and the business's applicable pump type:
one. For media that has a temperature decrease than one hundred twenty°C, there is generally no special cooling procedure, as well as medium by itself is used for lubrication and cooling. Which include DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (defense amount of shielded motor ought to exceed H quality when in excess of 90°C); and DFCZ prevalent variety and IH chemical pump can use temperature to adopt suspension framework The upper Restrict is 140°C ~ a hundred and sixty°C; IHF lining fluorine pump can be utilized up to two hundred°C; only CQB normal magnetic pump use temperature would not exceed one hundred°C. It is worthy of mentioning that the medium that is not hard to crystallize or is made up of particles should be Outfitted with a sealing floor flushing line (designed by having an interface).
2. For mediums above one hundred twenty°C and below 300°C, a cooling chamber shall be delivered within the pump address. The sealing chamber shall also be linked to the coolant (with double mechanical seal), in the event the coolant just isn't permitted to penetrate into the medium. It should be taken immediately after cooling its personal medium (might be understood by straightforward warmth exchanger).
three. For high temperature medium previously mentioned three hundred°C, don't just the pump head component ought to be cooled, but also the suspension bearing chamber needs to be Outfitted which has a cooling method. The pump construction is mostly in the shape of the central support. The mechanical seal is preferably a steel bellows form, but the worth is high ( The more info value is a lot more than ten situations that of a traditional equipment seal).
