Exhaust fan in the design of fire control system is like? Tall Building fire control target, generally have fire fighting equipment (fire pumps, spray pumps, etc.), smoke control facilities, fire shutter, fire elevators. One important facilities such as fire? Shaw anti pumps, spray pumps, smoke exhaust fan exhaust fan price and reliable start and stop, direct influence and determine the reliability of the entire fire control system. Therefore, "automatic fire alarm system design specifications": fire pumps, smoke and exhaust fan control device, when encoding module using the bus control unit, which means that these devices in addition to receiving the fire detector alarm signal sent by the self-start work, it must also be able to independently control the start and stop fire exhaust fan prices, not due to other non-fire-fighting equipment failures and affect their start and stop. That is, the use of such equipment can not be a single fire alarm system control module transmission bus encoding means to control the start and stop them, but also has a manual control function, by hardware circuits directly control operation start line. This is part of the design can not be ignored. Model Description: 1, the performance of fan performance table lists the properties of the kitchen exhaust fan in the most efficient range, according to the performance of the air volume is divided into five working points, according to prevail in the selection of the performance table. Fan factory is qualified products at rated air flow. 2, the wind turbine installation can be divided into horizontal and rooftop exhaust fan, such as when to air flow, total pressure, dimensions and other properties have special requirements, our company will provide you with a separate design and production. 3, HTF-Ⅰ, HTF-Ⅱ represents pressure type fire temperature exhaust fan, leaf type axial flow type: HTF-Ⅰ (single speed) and HTF-Ⅱ (double speed) of two; HTF-Ⅲ, HTF -Ⅳ representation pressure fire temperature exhaust 4, HTF-X as a silencer fire temperature exhaust fan, the user can choose according to the actual needs of different species. 5, HTF-W series rooftop fire temperature exhaust fan, the user can choose according to actual needs retardant fiberglass hood or steel hood. 6, HTF-D as a low pressure type fire temperature exhaust fan. 7. Special Note: GYF and HTF series fan is like .S) overview, with the same machine number than the centrifugal fan large amount of wind, air pressure higher axial fans, and other characteristics can be axially mounted; low noise, low power consumption, efficient wide area, easy to install and use than the centrifugal fan, reliable operation. Features 1. Compact structure, easy installation, reliable operation; The fan than axial or centrifugal small size in the case of the same amount of wind, air pressure can be directly connected to the duct, horizontal or vertical installation, easy operation Features. 2. Low noise: The fan casing is specially designed to greatly reduce the outflow of noise. In the unit amount of wind, air pressure unit operating conditions, than A sound level can be reduced 2-3dB (A), while in the case of low speed, can obtain higher fan pressure. In the industrial and mining enterprises and senior civil ventilation system can replace the low-pressure centrifugal fan or replaced without the need for a large number of high-pressure axial fan silencer measures. 3. Wide range of applications: This series points single-speed and two-speed two models, according to different occasions, changing the mounting angle of the fan, change the number of leaves and converting speed to its requirements. The Experimental Study of T35 axial fan FT35 corrosion axial fan BT35 proof axial fans BFT35 flame proof axial fan axial fan axial fan type structure form T35 by determining the airfoil axial fans, with a cylinder shaped hub structure, axial fan motors were modified design, axial fan structure reduces the flow losses, thus the efficiency of axial flow fan outlet area of ??a circle by up to 77% calculated box exhaust fan, axial fans Press exit loop area calculation increased to 89.5%, axial fan A sound level lower than 3.6 dB. T35 axial flow fan according to the impeller diameter is divided into 13 machine number, in order of priority is: №2.8,*,3.55,4,4.5,5,5.6,6.3,7.1,8,9,10,11.2. Each machine axial fan number is divided into 15 °, 20 °, 25 °, 30 °, 35 ° and other five kinds of blade mounting angle. T35 axial flow fan numbers are used for each machine impeller and motor directly connected to the structure. Axial fan impeller peripheral speed of not more than 60m / s condition, equipped with three kinds of speed: 2900,1450,960r / min jgf exhaust fan, the intake side of the impeller axial direction of the fan. Note: Axial fans equipped with three-phase motors in general, if you need single axial fan, please specify when ordering. paiyanfpaiyan xgf exhaust fan, exhaust fan where the good (certified), provided by the Shandong Liaoyuan exhaust fan Fan Air Conditioning Equipment Co.
