The transportation of higher-temperature medium puts increased prerequisites around the structure, supplies and auxiliary method from the pump. Let's talk about the cooling requirements of various temperature improvements and the corporation's relevant pump sort:
1. For media with a temperature lessen than a hundred and twenty°C, there is often 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 standard of shielded motor need to exceed H grade when around 90°C); and DFCZ typical style and IH chemical pump can use temperature to undertake suspension structure The higher limit is a hundred and forty°C ~ one hundred sixty°C; IHF lining fluorine pump can be employed as many as 200°C; only CQB everyday magnetic pump use temperature isn't going to 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 equipped which has a sealing surface area flushing line (built using an interface).
two. For mediums over a hundred and twenty°C and beneath three hundred°C, a cooling chamber shall be supplied to the pump include. The sealing chamber shall even be linked to the coolant (with double mechanical seal), once the coolant will not be allowed to penetrate to the medium. It ought to be taken following cooling its possess medium (can be recognized by very simple heat exchanger).
3. For prime temperature medium higher than 300°C, not merely the pump head aspect must be cooled, and also the suspension bearing chamber must be Geared up with a cooling program. The pump framework is normally in the form of a central help. The mechanical seal is ideally a steel bellows style, but the price is large ( The cost is in excess of ten times that of click here a normal machine seal).
