SERIE 5000&6000 – SINGLE SURFACE

Centrifugal Fan with curved blades

LIMIT-LOAD – HEAVY-DUTY

BASIC DESCRIPTION

Centrifugal fan with backward curved blades, SINGLE SURFACE, LIMIT-LOAD, HEAVY-DUTY, high efficiency, developed, tested and certified by Chicago Blower Corporation. With rotor blades backward curved, designs 5500, 5800, 6100, 6105 and 6195. Width change percentage of the rotors from 40% to 110%.

APLICATIONS:

Industrial processes, mining, refineries, steel mills, platforms, paint systems, automotive industries, chemical and petrochemical industries, pollution control systems, etc..

OPERATING CHARACTERISTICS:

Operating Range: Flows and pressures according to the needs of each project, with wide range of sizing.
Mechanical efficiency: Above 80% in the range of maximum yield
Power consumption profile: "LIMIT-LOAD"
Operated fluid: air or gases without excess abrasive particles.
Temperature: Up to 120°C – Standard construction. Above, up to 600 °C – Requires special fittings.

CONSTRUCTION: (INDUSTRIAL HEAVY-DUTY)

● Structure - Profiles of welded carbon steel plates, providing security and robustness to the equipment.
● Housing - High thickness carbon steel plates, welded, with aerodynamic "spiral" shape.
● Inlet cone - Carbon steel conformed to hyperbolic flow profile.
● Rotor - Designed with a minimum safety factor of 1.2 on the maximum speed of the class, consisting of:
   - Center - Carbon steel precision machined, fixed to the shaft with screws and "key" or assembled by interference according to the class.
   - Backplate - Carbon steel disc, high thickness, structured, centerly fixed with locked screws.
   - Blades - Carbon steel, with simple surface, backward curved (LIMIT-LOAD), welded to the back plate and the cone rotor.
   - Rotor cone - Carbon steel conformed to hyperbolic flow profile.
● Shaft - Carbon steel SAE 1045 precision machined, minimum safety factor of 1.2 on the maximum speed of the constructive class.
● Bearings - Calculated for a minimum life L10 of 40,000 hours.
● Transmission (when applicable) - Pulleys and "V" belts, calculated for a minimum of 1.5 times the power of the drive, or flexible coupling "elastic sleeve" type.
● Welding - Electrical in an inert atmosphere with qualified procedure and operators.
● Balancing - All rotating assembly is subjected to rigorous static and dynamic balancing, according to ISO 1940 and ANSI S2.19, grade G = 6.3.

SURFACE TREATMENT

According to the procedure of the standard paint of SOMAX the carbon steel parts are subjected to surface treatment by abrasive blasting grade SA-2, further epoxy based paint with a minimum thickness of 25µ and epoxy finishing paint with a minimum thickness of 25µ . Other materials of construction and other surface treatments can be provided upon request.
