The transportation of substantial-temperature medium puts increased demands to 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 sort:
1. For media with a temperature lessen than one hundred twenty°C, there is often no Particular cooling method, as well as the medium by itself is used for lubrication and cooling. Which include DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (defense amount of shielded motor ought to exceed H quality when above 90°C); and DFCZ prevalent 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 up to two hundred°C; only CQB normal magnetic pump use temperature would not exceed one hundred°C. It is truly worth mentioning the medium that is simple to crystallize or has read more particles needs to be Geared up using a sealing area flushing line (created having an interface).
2. For mediums earlier mentioned 120°C and underneath three hundred°C, a cooling chamber shall be offered over the pump go over. The sealing chamber shall even be connected to the coolant (with double mechanical seal), once the coolant isn't allowed to penetrate into your medium. It should be taken soon after cooling its own medium (could be understood by simple heat exchanger).
three. For top temperature medium earlier mentioned 300°C, not just the pump head aspect needs to be cooled, but in addition the suspension bearing chamber need to be equipped by using a cooling procedure. The pump construction is mostly in the shape of the central aid. The mechanical seal is preferably a metal bellows sort, but the cost is superior ( The price is greater than 10 moments that of a traditional equipment seal).
