When the chemical process pump in the delivery of high temperature medium, which set the chemical pump on the structure, materials and auxiliary systems put forward higher requirements, but it also involves the chemical process pump cooling problems, mainly Different cooling problems under changing temperature. The following small series to tell you about the chemical process pump cooling problems have what the requirements are as follows: chemical process pump cooling problem 1. For temperatures below 120 ℃ medium, usually do not set a special cooling system, use more of their own media To lubricate and cool. DFL (W) H chemical pump, DFL (W) PH shield chemical pump (class H should be used for shielded motor over 90 ℃); DFCZ common type and IH chemical pump can make the temperature Up to 140 ℃ ~ 160 ℃; IHF lined with fluorine pump up to a maximum temperature of 200 ℃; only CQB ordinary magnetic pump temperature does not exceed 100 ℃. It is worth mentioning that for the easy-to-crystallize or media containing particles should be equipped with a sealing surface flushing pipe (design have left interface). 2. For media above 120 ° C and within 300 ° C, a cooling chamber is normally to be provided on the pump cover and the seal chamber is also to be filled with coolant (to be fitted with a double-ended mechanical seal). When coolant is not allowed to penetrate the medium , It should be taken after the cooling medium itself access (through a simple heat exchanger). The company has DFCZ chemical process pump, GRG high temperature pipeline pump and HPK hot water circulation pump (under development) to choose from, the other CQB-G high temperature magnetic pump can be used within 280 ℃ high temperature medium 3. For more than 300 ℃ High-temperature medium, not only need to cool the pump head part, the suspension bearing chamber should also be equipped with cooling system, the pump structure is generally the central support form, the mechanical seal is best to use metal bellows type, but the price is high (the price is normal mechanical seal 10 Multiple). There are currently DFAY centrifugal pump temperature can reach 420 ℃ (under development).
