The transportation of substantial-temperature medium puts larger necessities to the framework, resources and auxiliary technique on the pump. Let's discuss the cooling specifications of different temperature changes and the company's relevant pump variety:
1. For media with a temperature lower than a hundred and twenty°C, there is frequently no Specific cooling method, and also the medium alone is employed for lubrication and cooling. Including DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (protection volume of shielded motor need to exceed H grade when around 90°C); and DFCZ common sort and IH chemical pump can use temperature to adopt suspension framework The upper Restrict is 140°C ~ a hundred and sixty°C; IHF lining fluorine pump can be utilized 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 needs to be Geared up using a sealing area flushing line (created having an interface).
2. For mediums higher than 120°C and underneath 300°C, a cooling chamber shall be presented on the pump more info protect. The sealing chamber shall even be connected to the coolant (with double mechanical seal), if the coolant is not allowed to penetrate in the medium. It should be taken soon after cooling its have medium (could be understood by straightforward warmth exchanger).
three. For high temperature medium earlier mentioned three hundred°C, not just the pump head portion really should be cooled, but additionally the suspension bearing chamber really should be Geared up having a cooling technique. The pump framework is usually in the shape of the central support. The mechanical seal is preferably a steel bellows form, but the worth is high ( The value is a lot more than ten periods that of a traditional equipment seal).
