The transportation of significant-temperature medium puts greater needs within the construction, components and auxiliary program in the pump. Let's discuss the cooling specifications of different temperature changes and the organization's applicable pump type:
one. For media which has a temperature lessen than a hundred and twenty°C, there is frequently no Specific cooling technique, along with the medium by itself is utilized for lubrication and cooling. Like DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (protection volume of shielded motor should really exceed H quality when about ninety°C); and DFCZ frequent kind and IH chemical pump can use temperature to adopt suspension composition The higher limit is 140°C ~ 160°C; IHF lining fluorine pump can be employed as many as 200°C; only CQB normal magnetic pump use temperature does not exceed a hundred°C. It truly is well worth mentioning that the medium check here that is easy to crystallize or incorporates particles really should be Outfitted having a sealing surface flushing line (intended using an interface).
2. For mediums above a hundred and twenty°C and under 300°C, a cooling chamber shall be delivered to the pump go over. The sealing chamber shall also be linked to the coolant (with double mechanical seal), once the coolant isn't permitted to penetrate to the medium. It should be taken just after cooling its possess medium (could be realized by uncomplicated heat exchanger).
three. For prime temperature medium over three hundred°C, not merely the pump head component really should be cooled, but in addition the suspension bearing chamber ought to be Geared up by using a cooling method. The pump composition is usually in the form of the central assistance. The mechanical seal is if possible a steel bellows style, but the cost is higher ( The worth is over ten moments that of a normal device seal).
