Low noise centrifugal fan installed Texas Pacific sales agent fan centrifugal fan models complete

Low noise centrifugal fan installation | sales agent in Texas Pacific fans | centrifugal fan models complete low-noise fiberglass straight centrifugal blower fan has the following characteristics: Fans of the series can be connected directly with the pipeline, easy to install, reliable performance, reduce costs, save space; air conditioning can be widely used in train, bus air-conditioning and other needs of the occasion, air volume, high efficiency; ultra low noise, anti-corrosion. YTCL high pressure FRP Direct low noise centrifugal fan is widely used in ventilation, fire smoke, central air-supporting, air purification, filtration equipment and require relatively low noise applications, such as: office buildings, hotels, auditoriums, theaters, shopping malls, hospitals, basements, workshops and other factories require ventilation of the premises. Optimum operating point centrifugal fan before 1/3 of the fan characteristic curve, namely high pressure range; fan cooled card from the distance is greater than one times the minimum thickness of the fan; the fan outlet to avoid being for local personnel to operate the front of the device; cooling fan power consumption shall not exceed 10% of the whole device 4.2.3 Hair and ventilation system selection principles when things heat unevenly distributed, the need for a dedicated area for centralized cooling, the use of hair way, directly at the outlet portion is cooled, concentrated amount of wind, air pressure; the system is pressurized, dust and other difficult to enter. The disadvantage is that the wind speed is uneven, the presence of dead zone (low zone), depending on the inlet air, may also be in the local recirculation zone; Into the airflow through the fan, the temperature was increased. When the resistance is larger and more uniform heat distribution, the use of ventilation mode, the system uses exhaust dead zone does not exist, even wind speed can be more evenly flowing through the cooling surface; the negative is a negative pressure system in harsh environment dust easily enters, the higher the fan where the ambient temperature, affect life expectancy. 4.2.4 Characteristics of series and parallel fan when the system air pressure is not enough, fans can work in series, in order to improve their work pressure. The fan series, the fan characteristic curve changes; the air flow of each fan (slight increase) in the air flow, and pressure was the same amount of wind under the pressure of two fans and when the duct curve is relatively flat, the need to increase When the wind volume, the system can be used in parallel, when the fan used in parallel, their pressure than a single fan air pressure slightly increased, while the total amount of wind fan flow is the sum of all the advantages of a parallel system of airflow path is short, resistance small loss, more uniform air distribution, but low efficiency. 4.2.5 Fan speed control reduces system noise, fan noise is closely related to its rotational speed, reduce speed, fan noise significantly reduced life expectancy is one of the weaknesses of the system, controlling the fan speed can extend fan life and improve the system reliability; control the fan speed can also save energy, the fan at low speed, can reduce energy consumption and improve overall efficiency.
