河南粉末输送泵简介
河南粉末输送泵是一种新型的粉体气力输送设备,属于低压稀相输送类别,利用高速气流的引射作用来输送粉状物料,在当量距离450m,提升高度40m范围内使用效果*。目前广泛应用于粉煤灰、氧化铝粉、干窑灰、焦粉、水泥粉料等干燥松散粉料的中短距离输送。
LFB-1系列粉末输送泵是我厂在引进国外先进技术的基础上,针对国内不同类型气力输送设备存在的各种问题和建材院合作而开发出的新型低压气力输送泵,该产品广泛适用于电力除灰、水泥均化及倒库、各种粉状物料的输送,*低耗、全封闭、,没有维护、气源可选用罗茨风机、压缩空气。
河南粉末输送泵工作原理
河南粉末输送泵是利用气流射流作用,使空气带动灰粒把灰送到灰库,粉末输送泵主要有四部分组成分别为喷嘴、圆柱形泵体、喷嘴调节装置、底部汽化装置,粉末输送泵工作时的能量来自二部分:一部分是风机的动能,另一部分是料柱的势能。料柱高、势能大、压力大、输送量相应就大,反之则小。
河南粉末输送泵正常工作时保持一定的料位高度,当短时间内电收尘下料量增大而粉末输送泵仍正常工作则料位高度自然升高,随着料位高度的提高料压增大势能增加输送量相应就大直到系统自动平衡,当短时间内电收尘下料量减少而粉末输送泵仍正常工作则料位高度自然降低,随着料位高度的降低、料减少势能降低、输送量相应就小,直到系统自动平衡。
河南粉末输送泵优点
1、设备投资小,用一台粉末输送泵可替代二台仓泵,降低了设备投资。2、粉末输送泵的用气压力为0.04Mpa-0.1Mpa,降低了供气压力,节约了耗气量,同时降低了电机功率。
3、降低了维修费用。该系统一次安装调试投运后,基本不用操作,几乎没有维护量,检修工只须定期检查即可。
4、低压力输送,设备密封性较好,运行可靠,无堵管现象,环境面貌*完善
该设备自投放市场以来经多家使用证明该泵与仓式泵、斗式提升机等设备相比,具有体积小,风压低(0.2--1大气压,一般不需空压机,只配罗茨 风机即可)、易布置、无扬尘、符合环保要求等一系列优点。广泛用于 电力、建材、化工等领域,是在当量距离680m,高度50m内用来提升输送水泥、生料、粉煤灰等粉状物料的理想设备,该粉末输送泵主要特点是使用寿命长、运转可靠,几乎没有维修量和磨损件.
