The transportation of substantial-temperature medium puts increased 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 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 around 90°C); and DFCZ typical style and IH chemical pump can use temperature to adopt suspension structure The higher limit is a hundred and forty°C ~ 160°C; IHF lining fluorine pump may be used as much as two hundred°C; only CQB regular magnetic pump use temperature does not exceed one hundred°C. It's truly worth mentioning the medium that is easy to crystallize or has particles ought to be Geared up having a sealing area flushing line (created having an interface).
2. For mediums earlier mentioned 120°C and underneath 300°C, a cooling chamber shall be presented on the pump protect. The sealing chamber shall even be click here connected to the coolant (with double mechanical seal), once the coolant is not really allowed to penetrate in the medium. It ought to be taken right after cooling its individual medium (may be recognized by very simple heat exchanger).
3. For prime temperature medium higher than 300°C, not merely the pump head section must be cooled, and also the suspension bearing chamber should be equipped by using a cooling procedure. The pump structure is usually in the form of a central guidance. The mechanical seal is if possible a metallic bellows kind, but the value is substantial ( The worth is more than 10 occasions that of a standard machine seal).
