The Impression Of Cooling Complications On Chemical Pumps

The transportation of high-temperature medium puts larger specifications on the framework, components and auxiliary method of your pump. Let's talk about the cooling necessities of different temperature variations and the corporate's applicable pump form:



1. For media that has a temperature reduced than a hundred and twenty°C, there is normally no special cooling technique, and the medium by itself is used for lubrication and cooling. For example DFL (W) H chemical pump, DFL (W) PH shielding chemical pump (protection amount of shielded motor should exceed H grade when around 90°C); and DFCZ prevalent type and IH chemical pump can use temperature to undertake suspension composition The upper limit is a hundred and forty°C ~ 160°C; IHF lining fluorine pump may be used up to 200°C; only CQB standard magnetic pump use temperature does not exceed one hundred°C. It can be really worth mentioning the medium that is simple to crystallize or contains particles must be Geared up with a sealing surface area flushing line (made having an interface).



2. For mediums over one hundred twenty°C and down below 300°C, a cooling chamber shall be supplied about the pump address. The sealing chamber shall get more info even be connected to the coolant (with double mechanical seal), once the coolant is just not permitted to penetrate into your medium. It ought to be taken following cooling its very own medium (might be understood by very simple warmth exchanger).



three. For high temperature medium over 300°C, not merely the pump head portion ought to be cooled, but will also the suspension bearing chamber should be equipped having a cooling method. The pump construction is usually in the form of a central assistance. The mechanical seal is preferably a metal bellows kind, but the value is large ( The value is over 10 instances that of a normal machine seal).
