The Affect Of Cooling Issues On Chemical Pumps

The transportation of superior-temperature medium places bigger requirements on the structure, 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 by using a temperature decrease than 120°C, there is usually no Distinctive cooling process, along with the medium itself is useful for lubrication and cooling. For instance DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (safety level of shielded motor should really exceed H grade when more than ninety°C); and DFCZ frequent kind 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 can be used nearly 200°C; only CQB everyday magnetic pump use temperature isn't going to exceed 100°C. It can be well worth mentioning which the medium that is not difficult to crystallize or click here consists of particles need to be equipped which has a sealing surface area flushing line (built with the interface).



two. For mediums earlier mentioned 120°C and down below 300°C, a cooling chamber shall be presented around 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 into your medium. It should be taken soon after cooling its own medium (could be understood by simple heat exchanger).



three. 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 equipped by using a cooling procedure. The pump structure is usually in the form of a central guidance. The mechanical seal is if possible a metal bellows kind, but the value is substantial ( The worth is more than 10 occasions that of a standard device seal).
