The Influence Of Cooling Issues On Chemical Pumps

The transportation of high-temperature medium puts greater demands about the framework, components and auxiliary program in the pump. Let's discuss the cooling specifications of various temperature variations and the corporation's relevant pump variety:



1. For media with a temperature lessen than a hundred and twenty°C, there is often no Particular cooling program, and 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 need to exceed H grade when around 90°C); and DFCZ typical style and IH chemical pump can use temperature to adopt suspension structure The higher limit is a hundred and forty°C ~ 160°C; IHF lining fluorine pump can be employed approximately 200°C; only CQB standard magnetic pump use temperature will not exceed a hundred°C. It is worth mentioning the medium that is simple to crystallize or incorporates particles must be equipped by using a sealing surface flushing line (made with an interface).



2. For mediums above 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 your medium. It should be taken immediately after cooling its personal medium (might be understood by easy heat exchanger).



three. For top temperature medium over three hundred°C, don't just the pump head component should be cooled, but will 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 variety, but the worth is check here high ( The price is over 10 periods that of a traditional equipment seal).
