5 Fabrication and technical standards
5.1 Bedplate: welded by superior U steel and high-quality steel plate.
5.2 Mixing chamber: "W" shape jacket structure, consisting of chamber body and side plates, all of which are welded by superior steel plate through aging treatment, inner side walls are hard chromium coating up to 0.12-0.15mm thick, hardness is around HRC50. Cavity of the jacket could pass through cooling water or heating steam. There is a plug-in type thermocouple fitted at bottom of the chamber, which is used for monitoring compound temperature.
5.3 Rotor assembly: rotor assembly is made up of rotor shaft, rotor body and rotor wing blades, rotor wing blades and other working surfaces are through processing and polishing, hard chromium coating up to 0.12-0.15mm thick, hardness is around HRC50. Rotor shaft is with hollow structure, where there are pre-made holes extending to hollow cavity of the wing blades, therefore, forced cooling or heating rotor is possible. Dust stop of rotor ends are adopted with inlay type alloy moveable ring and fixed sealing ring. Inlay type alloy movable sealing ring is up to 8mm thick, hardness is around HRC55, the fixed sealing ring is made of 10-1 copper, which is embedded PTFE with self-lubricating function, this dust stop system is pretty reliable and featuring of an extra long service life.
5.4 Frame: welded by high-quality carbon constructional steel plate through vibration treatment.
5.5 Main air cylinder: cylinder inner side walls are through fine polishing treatment, so as to increase service life.
5.6 Upper ram: "M" shape jacket structure, welded by high-quality steel plate, through aging treatment and polish processing, hard chromium coating up to 0.12-0.15mm thick, hardness is around HRC50. There is inlaid wear-resistant sealing strip made of bakelite resin surrounding the ram. Jacket cavity of the upper ram could pass through cooling water or heating steam to achieve specific mixing result.
5.7 Tilting device: mixing chamber tilting device is driven by motorized worm &gears or hydraulic oil cylinder powered by hydraulic station.
5.8 Main motor: installation dimension and power grade are all in line with international standards.
5.9 Hard-tooth gear box: made of 20CrMnT, through carburizing and quenching treatment.
