CONSTRUCTION (ROBUST INDUSTRIAL)

● Panel - High thickness carbon steel plate, structured with square shaped folds, welded to the base of the drive, providing security and robustness to equipment.

● Housing (optional) - In high thickness carbon steel, welded, with aerodynamic "spiral" shape, bolted to the panel.

● Inlet cone (optional) - carbon steel conformed to hyperbolic flow profile, can be supplied with or without drilling, with brackets for mounting to the panel or screwed to the frame (optional).

● Rotor - Designed with minimum safety factor of 1.2 on the speed of the class consisting of:

-Center - Carbon steel precision machined, fixed to the shaft with screws and key.

-Backplate - Carbon steel disc, high thickness, structured, centerly fixed with locked screws.

-Blades - Carbon steel, backward inclined, welded to the back plate and the cone of the rotor.

.

-Rotor Cone- Carbon steel conformed to hyperbolic flow profile.

● Shaft (Arrangement 9) - Carbon steel SAE 1045 precision machined, minimum safety factor of 1.2 on the maximum speed of the constructive class.

● Bearings (Arrangement 9) - Calculated for a minimum life L10 of 40,000 hours.

● Transmission (Arrangement 9) - Pulleys and "V" belts, calculated for a minimum of 1.5 times the power of the drive.

● Welding - Electric in an inert atmosphere with qualified procedures 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.
