Tough demands are placed on the sealing systems in use when in­dus­trial plants are to operate without re­stric­tions in a wide range of ap­pli­ca­tions. Espey® carbon floating ring seals by EagleBurgmann Espey offer the optimum solution: from simple, standard fans with straight­for­ward re­quire­ments up to special fans for large pressure in­creases; fans that may also be subject to ex­tremely dif­fi­cult con­di­tions such as flue gases or po­ten­tially ex­plo­sive en­vi­ron­ments. All these factors - the ro­bust­ness, the wide range of op­er­at­ing pa­ra­me­ters, and the large number of ap­pli­ca­tion-spe­cific optional mod­i­fi­ca­tions to the seal - have con­tributed to decades of suc­cess­ful ap­pli­ca­tions in almost every in­dus­trial sector, such as plant con­struc­tion, chemical and petro­chem­i­cal en­gi­neer­ing, power plant tech­nol­ogy, waste disposal, the steel industry and vapour com­pres­sion.

APPLICATION EXAMPLE: SEALING OF A CONTINUOUS KILN FOR HEAT TREATMENT

Issue and chal­lenge:

Industrial processing system with piping, motors, and service platform in a manufacturing facility.

The manufacture of precision strips with extremely close tolerances from copper and copper alloys requires a continuous kiln with heating and cooling zones for tempering the strip in closed chambers containing an inert gas atmosphere. The tempering process permits recrystallization after previous rolling, in order to achieve the desired mechanical and physical parameters such as expansion, grain size and strength. The strips are transported through the plant without contact on a gas cushion generated by a system of nozzles. The energy required by the flow of gas for this purpose is provided by fans. For reasons of assembly and servicing, the fan motors are mounted outside the chambers. Since very little space is available, the entry of the shafts into the processing area must be implemented with a very short shaft seal. This system protects the copper strips from the oxygen in the atmosphere.
