PYHL-14A Axial-Flow Smoke Exhaust Fan for Fire Protection

HL3-2A Mixed-Flow Ventilator, PYHL-14A Axial-Flow Smoke Exhaust Fan

Applications

The HL3-2A mixed-flow ventilator is used for ventilation and air exchange; the PYHL-14A axial-flow smoke exhaust fan can be used for both high-temperature smoke exhaust and ventilation. The operating conditions are as follows:

1. Applications: The HL3-A model is used for ventilation and air exchange in air-conditioning projects for refrigeration, air conditioning, textiles, ships, civil buildings, and other applications. The PYHL-14A model is used for high-temperature smoke exhaust in tunnels, underground garages, metallurgical facilities, and other applications. In the event of a fire, it can rapidly exhaust smoke and reduce the temperature, helping firefighters enter the affected area in time to extinguish the fire. It is an essential facility for fire safety.

2. Types of gases conveyed: Air and other gases that are non-flammable, harmless to humans, and non-corrosive to steel. Explosion-proof mixed-flow fans can be selected for special environments.

3. Impurities in the gas: The gas must not contain sticky substances. The content of dust and hard particles must not exceed 100mg/m³.

4. The HL3-2A ventilator can operate continuously in ambient temperatures from -20℃ to +45℃. The PYHL-14A axial-flow smoke exhaust fan can operate continuously for more than 30min at an ambient temperature of 280℃.


Structural Features

The fan mainly consists of an impeller, casing, inlet silencer, guide vanes, and motor. The impeller features welded blades with a twisted airfoil profile and meridional acceleration characteristics, mounted on the hub. After dynamic balancing and overspeed testing, it delivers excellent aerodynamic performance.

The casing is cylindrical and formed as a single piece using a fully automatic hydraulic flanging machine. It features patented rib-forming technology, providing high strength and good roundness.


Performance and Selection

1. Fan performance can be found in the performance table. The listed performance values are within the maximum-efficiency range and are divided into five operating points by airflow rate. Select the fan according to the performance table.

2. For factory-qualified fans, the total pressure at the rated airflow rate does not deviate by more than ±5%.

3. The selection table shows performance under standard conditions. Performance specified in technical documents or order requirements is also based on standard conditions: atmospheric pressure pa=101325Pa, t =20℃, and air at a relative humidity of ψ=50%. If actual operating conditions differ from these, convert the values using the relevant formulas.

4. Fans can be installed vertically or horizontally. Specify vertical installation when ordering. If special requirements apply to performance parameters such as airflow rate, pressure, or installation dimensions, the manufacturer can design and manufacture the fan accordingly.

6. The noise values in the performance table are measured with ductwork installed.

Overall and Installation Dimensions


Overall and Installation Dimensions of the PYHL-14A Axial-Flow Smoke Exhaust Fan


image.png


Technical Notes:

1. The fan's overall dimensions are standardized. The length is generally based on the midpoint of the fan speed range; use this drawing as the reference when preparing drawings.

2. Dimensions should be machined as accurately as possible. The permitted deviation in the overall fan length is ±10mm, and the permitted deviation in the support leg dimensions is ±5mm.

Notes: 1. To ensure the installation dimensions required by the user, the base mounting holes (4-φ) are for reference only. Unless otherwise specified by the user, fan flanges are generally not drilled. Special requirements can be accommodated upon request.

2. Products below fan size 7# generally use a design without an inner cylinder. Special requirements can be accommodated upon request.


Overall and Installation Dimensions of the PYHL-14A Dual-Speed Axial-Flow Smoke Exhaust Fan

Technical Notes:

1. The fan's overall dimensions are standardized. The length is generally based on the midpoint of the fan speed range; use this drawing as the reference when preparing drawings.

2. Dimensions should be machined as accurately as possible. The permitted deviation in the overall fan length is ±10mm, and the permitted deviation in the support leg dimensions is ±5mm.
