HLF-6 Type Francis Wind Chassis

I. Product Overview

 Francis HLF-6 low-noise, energy-saving air box is a new kind of fan between axial and centrifugal fans among the same number of the machine than the centrifugal fan large amount of wind, air pressure higher axial fan with high efficiency , energy saving, low noise, easy installation. The main impeller fan, hairdryer, import collector, guide vanes, motor, box, inlet and outlet and other components. Meridian impeller has accelerated features twisted shaped leaves welded to the hub, the balancing test, speed test, with good aerodynamic performance. Duct silencer and streamlined collector connected into the overall functionality, built with guide vanes, with good air distribution, pressure stability. Meet the needs of modern high buildings lower noise.

 Second, product characteristics

 1, HLF-6 low-noise Francis wind chassis, box with frame, box board assembly is made by folding box board with high-quality steel, internal mezzanine for sound deadening material, ensures that the wind chassis lower noise. With low noise, vibration small, beautiful appearance, easy installation, easy maintenance features.

 2, HLF-6 wind chassis-type exhaust ventilation can be divided into two kinds, smoke type is PYHL-14A type Francis fan pack boxes, more than 60 minutes of continuous operation at high temperature medium temperature 3000C, 1000C temperature conditions continuous operation 20 hours / times without damage, can dual exhaust ventilation; ventilated for HL3-2A type Francis fan pack boxes, can be used for ventilation.

 Third, the product process

 1. Impeller: Baosteel produced blades made from high quality Q235 steel, metal cutting, hydraulic molding. Wheel Baosteel produced from high quality Q235 steel, hydraulic machine stretch forming. Leaves by special welding equipment welding protection of carbon dioxide gas. And by the significant number of hard-bearing balancing machine calibration, balancing accuracy G4.6 level and above.

 2, Hair Dryers: Baosteel produced from high quality steel with Q235 cutting shears, with three core Bending rounded, carbon dioxide gas welding. Spinning flow forming machine, beading machine spinning and then the two arc-shaped ribs on the barrel. Guarantee duct has sufficient strength, stiffness, elegant appearance.

 3, the inner tube: inner tube made of high quality steel Q235 Baosteel produced by cutting shears, with three core Coil rounded, with beading machine, including two arc-shaped spinning barrel ribs. To ensure that the inner tube has sufficient strength and rigidity. Wicket with plasma cutting cutting, hydraulic molding machines, with carbon dioxide protection welding.

 4, the muffler canister: cutting shears, three core coiling rounded, spinning machine spinning molding, beading machine beading. Spinning machine with a dedicated inlet flow forming, with conical porous plate welding, middle silencer cotton filling.

 5, cabinet: Cabinet profiles of metal roll forming cold-formed unit, box board for the duplex structure, the outer layer of Baosteel produced by the high-quality color-coated material shearing, bending, molding, cabinets layer for high-quality galvanized sheet, middle filled with polyurethane foam, good silencing effect. Box board and assembly methods for embedded profiles, improve fan seal, box board to ensure that the muffling effect, reducing the amount of air leakage fan.

 6. Chassis: heavy-duty metal chassis fan Cold Unit stretch forming C-production. C steel is a good quality of the new steel, mechanical properties of a section of the mechanical properties of the evolution of the channel formed, elegant appearance

 7, the assembly: After the fan assembly, X, Y, Z axis vibration velocity is less than 5.6mm / s.
