The transportation of large-temperature medium puts larger demands about the framework, resources and auxiliary technique on the pump. Let's discuss the cooling specifications of various temperature variations and the corporation's relevant pump variety:
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 standard of shielded motor need to exceed H grade when about 90°C); and DFCZ common form and IH chemical pump can use temperature to adopt suspension composition The upper Restrict is one hundred forty°C ~ 160°C; IHF lining fluorine pump can be employed around two hundred°C; only CQB common magnetic pump use temperature doesn't exceed a hundred°C. It's truly worth mentioning the medium that is easy to crystallize or has particles needs to be Geared up using a sealing area flushing line (created having an interface).
2. For mediums earlier mentioned 120°C and under three hundred°C, a cooling chamber shall be offered on the pump include. The sealing chamber shall even be linked to the coolant (with double mechanical seal), when the coolant is just not permitted to penetrate in to the medium. It ought to be taken after cooling its very own medium (is usually realized by basic 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 needs to be Geared up with a cooling method. The pump framework is mostly in the shape of the central support. The mechanical seal is preferably a steel bellows variety, but the worth is high ( The price here is over 10 periods that of a traditional equipment seal).
