| 深宏远六叶负压风机的特点： Shen hong yuan Six of the suction ventilators features: 一、 风扇叶片与多V皮带轮组的平衡校正由专业技术人员负责。采用国外先进技术电脑平衡校正仪器，等级达4级水准（G6.3），符合ISO1940钢性运转体技术,达国际品质要求。 1, fan blades and multi-V pulley group balance correction by professional technical staff. Use of advanced technology from abroad balance correction computer equipment, the standard grade of 4 (G6.3) and with the operation of the ISO1940 steel technologies to international quality requirements. 二、 本机所匹配的1HP马达采用全铝合金外壳，密封严、抽风效能好、耗电量少、每小时只须0.75度电力。 2. This machine-match 1HP All motors used aluminum alloy shell, Seal strict,Good ventilation efficiency, Less power consumption, Only 0.75 per hour of electricity. 三、 传动皮带采用PK多V皮带,耐磨损,运转时无传统皮带打滑及噪音的困扰。 3.more transmission belt use PK V belts, wear resistance, When running the not traditional belt slipping and noise nuisance. 四、 百叶窗的设计运用空气顺流原理,不需要使用电力及人员开关,美观大方,且可以防雨水侵入。 4. Louver air downstream use of the design principles, Do not use electricity and personnel switch, handsome generous, and can prevent water intrusion. 五、 主体外框采用FRP材质,可减少金属共鸣,且抗酸碱,防腐蚀,增加使用年限。(可连续使用10-20年) 5. FRP materials by the main frame, Metal resonance can be reduced ,And resistance Acid-base,anti-corrosion, and increase life span. (Continuous use for 10-20 years). 深宏远负压风机的降温原理： Shen hong yuan the suction ventilators coolingPrinciple: 负压风机是利用空气对流、负压换气的降温原理，由安装地点的对向---大门或窗户自然吸入新鲜空气,将室内闷热气体迅速，强制排出室外,任何通风不良问题均可改善,降温换气效果可达90%-97%。 suction ventilators Is to use air convection cooling principle of negative pressure ventilation, by the location of the installation of the doors or windows - to the natural inhalation of fresh air, indoor hot gas rapidly, from the mandatory outdoor, Any adverse problems can be improved ventilation, Ventilation cooling effect of up to 90% -97%. EVAPORATIVE COOLING (夏天在编织，洗染，生产&加工服装工厂等很容易达到40度用这种风机很容易降下7－12度。) Temperature can easily exceed 40℃in spining,knitting,dyeing,finishing & garments factory during the summer if they are not equipped with cooling system.Such high temperature reduces product quality & worker productivity.Evaporative cooling is the most common method for reducing the temperature inside a factory.Air conditioning or refrigeratuib systems can be used,but their installation and operation costs are usually prohibitive. Evaporative cooling is a process that reduces the temperature 7-12℃of air by the evaporation of water into the airstreams.As water is evaporated,energy is lost from the air reducing its temperature.Reduced temperature enters in to room and room become cool. EVAPORATIVE COOLING PAD AND EXHAUST FAN SYSTEM A Pad-and-Fan cooling system typically consists of axial flow |
