The transportation of superior-temperature medium puts better needs over the construction, products and auxiliary program of your pump. Let's mention the cooling requirements of different temperature improvements and the organization's relevant pump type:
1. For media that has a temperature lower than one hundred twenty°C, there is usually no Particular cooling process, and also the medium by itself is employed for lubrication and cooling. Such as DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (safety standard of shielded motor should really exceed H grade when above ninety°C); and DFCZ popular type and IH chemical pump can use temperature to adopt suspension framework The higher Restrict is a hundred and forty°C ~ 160°C; IHF lining fluorine pump can be utilized as many as two hundred°C; only CQB ordinary magnetic pump use temperature doesn't exceed one hundred°C. It truly is truly worth mentioning which the medium that is simple to crystallize or includes particles really should be Geared up which has a sealing surface flushing line (developed with the interface).
2. For mediums previously mentioned one hundred twenty°C and underneath three hundred°C, a cooling chamber shall be petrochemical process pump furnished over the pump cover. The sealing chamber shall also be linked to the coolant (with double mechanical seal), when the coolant is not allowed to penetrate into the medium. It should be taken following cooling its personal medium (could be realized by straightforward heat exchanger).
3. For high temperature medium above 300°C, not only the pump head part needs to be cooled, but also the suspension bearing chamber should be equipped with a cooling system. The pump composition is normally in the shape of a central help. The mechanical seal is preferably a metal bellows type, but the worth is superior ( The worth is in excess of ten instances that of a normal machine seal).
