PYHL-14A Type Fire Temperature Francis Fan

I. Product Overview

 Francis PYHL-14A low-noise, energy-saving fire temperature exhaust fan is a new fan between axial and centrifugal fans among the same number of the machine relatively large amount of wind centrifugal fan, air pressure than the axial fan high, with high efficiency, energy saving, low noise, easy installation. Widely used in hotels, restaurants, auditoriums, theaters, tunnels, underground garages, underground shopping malls, underground warehouses, senior construction sites, etc., are ideal for smoke ventilation products have been sold all over the country, the majority of users.

 Second, product characteristics

 A fan structure: the main impeller fan, hairdryer, import collector, guide vanes, motors and other components. Meridian impeller has accelerated features twisted shaped leaves welded to the hub, the balancing check, after the speed test, with good air performance; duct silencer and streamlined collector connected into the overall functionality, built with wicket , has a good air distribution, pressure stability.

 2, fan performance: PYHL-14A type Francis fire temperature exhaust fan can be used as high-temperature exhaust, ventilation dual, fully enclosed motor with built-in temperature, arranged a special motor cooling system, according to JB / T10281 -2001 "fire exhaust fan technology" standards designed by the national Fire Equipment quality supervision and inspection Center by GA211-1999 "high-temperature exhaust fan fire test method" high-temperature test, can at 300 ? high temperature continuous run for 60 minutes or more, and its performance relies on the domestic level.

 3. The front fan inlet using silencer-type flow line design, can further reduce the fan noise.

 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, 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, welding with conical porous holes in the middle silencer cotton filling.

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

 6, high temperature performance: cooling fan motor with a special system to ensure high temperature at 300 ? operating normally 60 minutes or more, at 100 ? for 20 hours / time is not damaged, full compliance with state fire codes.
