CONTINENTAL turbo blowers and turbo exhausters are made in accordance with current safety regulations. The various production phases undergo the checks provided for by the quality control plan to ensure that materials and assembly are free from defects. All machines are mechanically tested before dispatch. The centrifugal multistage machines (some times referred to as pumps, centrifugal machines, compressors, exhausters, blowers) are robustly designed and can be described as follows:
Construction
Casing
Depending on the model, the inlet and oulet heads and intermediate sections are made of either cast iron or aluminium. In order to suit the pressure requirements, it is possible to vary the number of stages with a maximum of *0 on the small machines and 7 on the larger ones. The heads and intermediate sections are spigotted to each other and clamped together by steel tie-rods. The inlet and outlet connections are normally mounted vertically, but if required may be oriented differently. Sealing between the components is ensured by the use of a compound sealant or, in certain cases, by ”O” rings.
Impeller Assembly
The impellers are cast in treated aluminium alloy, and for certain applications are fabricated by riveting. All impellers are statically balanced, then keyed to a ground carbon steel shaft. The complete rotor assembly is then dynamically balanced so as to ensure a minimum vibration amplitude of *0 MIC when running. Different types of impeller are available, i.e. radial or curved, which enables us to meet a wider variety of duties.
Bearing Housings
The bearings are mounted in independent cast iron housings. These housings are securely bolted to the inlet and outlet heads, and allow easy access for routine maintenance. The bearings are the only running contacts between the shaft and casing. Sealing of the housing is by graphitized straps, or on the larger machines by segmented carbon rings, which are held together by a stainless steel spring. Leakage is thus reduced to a minimum with this type of seal. In the case of aggressive gases, sealing is by the use of double mechanical seals. The bearings are lubricated either using grease for machines up to ***0 m3/h or by oil replenishment by a constant level oiler for the larger machines.
