The transportation of large-temperature medium puts greater needs about the construction, components and auxiliary program in the pump. Let's talk about the cooling requirements of various temperature improvements and the corporate's applicable pump kind:
1. For media by using a temperature decrease than one hundred twenty°C, there is generally no special cooling procedure, plus the medium by itself is used for lubrication and cooling. Which include DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (defense degree of shielded motor should exceed H quality when above ninety°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 actually value mentioning that the medium click here that is a snap to crystallize or includes particles should be Outfitted with a sealing floor flushing line (designed by having an interface).
2. For mediums previously mentioned a hundred and twenty°C and under three hundred°C, a cooling chamber shall be offered over the pump go over. 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 immediately after cooling its very own medium (is often realized by straightforward 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 must be Geared up with a cooling program. The pump framework is normally in the shape of a central assistance. The mechanical seal is ideally a steel bellows style, but the price is higher ( The value is in excess of ten situations that of a normal machine seal).
