The Effects Of Cooling Problems On Chemical Pumps

The transportation of superior-temperature medium places bigger requirements around the structure, materials and auxiliary system of the pump. Let us take a look at the cooling prerequisites of various temperature alterations and the business's applicable pump type:



one. For media that has 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 quality when more than ninety°C); and DFCZ widespread kind and IH chemical pump can use temperature to adopt suspension composition The higher limit is 140°C ~ one hundred sixty°C; IHF lining fluorine pump can be used nearly 200°C; only CQB ordinary magnetic pump use temperature won't exceed 100°C. It can be well worth mentioning which the medium that is not difficult to crystallize or consists of particles need to be Outfitted which has a sealing surface area flushing line (built using an interface).



two. For mediums over a hundred and twenty°C and below three hundred°C, a cooling chamber shall be provided about the pump cover. The sealing chamber shall also be linked to the coolant (with double mechanical seal), when the coolant just isn't permitted to penetrate into the medium. It should be taken just after cooling its very own medium (is often realized by straightforward warmth exchanger).



three. For high temperature medium previously mentioned three hundred°C, not only the pump head element ought to be cooled, but also the suspension bearing chamber must be Geared click here up with a cooling program. The pump framework is normally in the shape of a central assistance. The mechanical seal is ideally a metallic bellows style, but the price is large ( The cost is in excess of ten times that of a normal machine seal).
