The Impression Of Cooling Complications On Chemical Pumps

The transportation of significant-temperature medium places better requirements on the composition, materials and auxiliary system of the 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 120°C, there is generally no special cooling procedure, plus the medium by itself is used for lubrication and cooling. Which include DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (defense degree of shielded motor must exceed H quality when about 90°C); and DFCZ common form and IH chemical pump can use temperature to adopt suspension composition The upper Restrict is one hundred forty°C ~ 160°C; IHF lining fluorine pump can be employed around two hundred°C; only CQB common magnetic pump use temperature doesn't exceed a hundred°C. It website really is worth mentioning the medium that is simple to crystallize or incorporates particles needs to be Geared up by 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 presented on the 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 right after cooling its have medium (could be recognized by simple heat exchanger).



3. For top temperature medium above 300°C, not simply the pump head section has to be cooled, and also the suspension bearing chamber should be equipped that has a cooling system. The pump construction is usually in the shape of the central aid. The mechanical seal is preferably a metal bellows sort, but the cost is superior ( The price is greater than 10 instances that of a standard device seal).
