一、电动脚踏两用风机产品简介
DJF-1电动脚踏两用风机是人防工事,防空地下室在战时电源被毁,敌方使用原子、化学或细菌武器的情况下,采用滤毒式通风设备。其技术指标的重点,是*保*战时人力驱动情况下,满足400人单元的滤毒式通风要求,同时,考虑到平、战结合,可利用人力驱动电源为人防工事、地下旅馆、餐厅和商场等进行通风换气。
二、电动脚踏两用风机主要技术
1、战时(脚踏驱动)在四个人驱动,脚踏转速为n=40转/分时。风量:Q≮1200立方公尺/小时风压:(全压):P≮120毫米水柱四个一般体力的人,能连续运转20分钟以上。
2、平时(电动)
用Y90S-4电动机传动(电机功率N=1。1千瓦,转速n=1400转/分,电源为三相380伏)
风量:Q=2600~3060立方米/小时墙风压(全压)P=90~60毫米水柱

三、电动脚踏两用风机产品尺寸
三、DJF-1电动脚踏两用风机安装
1.安装前应仔细检查通风机各连接部分,叶片与机壳是否有碰擦现象。按图校正风口与叶轮之间间隙尺寸,而保持为水平位置。
2.如机架为散装件装箱,则应先将散装件按DJF-1型风机外形尺寸图整装成机架后,按图示地脚螺栓尺寸,共(11处)分别将机架及增速箱固定到位,尽量使两轴线同心并在其连接处“铰链联轴器”上装园推销。然后按使用说明书维护保养一节进行电动、脚踏变换工况(工况变换手把设在增速箱一侧)试运转。
四、DJF-1电动脚踏两用风机维护保养
脚踏电动两用风机的经常工作方式是电动。只有在战时才使用脚踏。但一旦使用,都是危急情况,要确保能可靠运转,所以,平时要加强维护保养,特别是各运动部分。
1.检查齿轮箱有无漏油和渗油,必要时更换密封垫圈。
2.对链条、牙盘和飞轮均要定期加润滑油,不使锈蚀。
3.检查支架部分结构,有否锈蚀损坏或失落紧固件。
4.齿轮箱维护:打开齿轮箱检查润滑油,若已变质,则倒尽后加新的120号机油,若油量不足,则加添到油平面与轴的下表面齐平。然后由一人慢速运转,检查有否相擦或撞击声。若无故障,则四个人同时运转5分钟,若有故障,应及时进行修理或更换零件。
5.风机长期不使用,将皮带卸下,或将电机底板调松,使皮带松驰。
