The transportation of large-temperature medium puts larger necessities to the framework, elements and auxiliary process with the pump. Let's speak about the cooling needs of different temperature changes and the company's relevant pump form:
1. For media having a temperature lower than a hundred and twenty°C, there is frequently no Specific cooling program, and also 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 ninety°C); and DFCZ typical type and IH chemical pump can use temperature to undertake 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 truly is really worth mentioning which the medium that is more info straightforward to crystallize or contains particles really should be equipped that has a sealing surface area flushing line (intended with the interface).
two. For mediums over 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 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 additionally the suspension bearing chamber must be Geared up with a cooling program. The pump framework is normally in the shape of a central assistance. The mechanical seal is ideally a steel bellows form, but the price is superior ( The value is a lot more than ten situations that of a normal machine seal).
