圆振动筛

产品介绍:


        圆振动筛是一种做圆形振动、多层数、高效新型振动筛。圆振动筛采用筒体式偏心轴激振器及偏块调节振幅,物料筛淌线长,筛分规格多,具有结构可靠、激振力强、筛分效率高、振动噪音小、坚固耐用、维修方便、使用安全等特点,该振动筛广泛应用于矿山、建材、交通、能源、化工等行业的产品分级。


概念:

  振(zhen)(zhen)(zhen)(zhen)动(dong)(dong)(dong)(dong)筛按振(zhen)(zhen)(zhen)(zhen)动(dong)(dong)(dong)(dong)频(pin)率(lv)是否接近或远离共振(zhen)(zhen)(zhen)(zhen)频(pin)率(lv)分为共振(zhen)(zhen)(zhen)(zhen)筛和惯性(xing)(xing)振(zhen)(zhen)(zhen)(zhen)动(dong)(dong)(dong)(dong)筛。共振(zhen)(zhen)(zhen)(zhen)筛曾一度崛起,受到各国普遍重视(shi),发展很快;但在生产实践中,暴露出(chu)结构复(fu)杂、调整困难、故(gu)障较多等缺点(dian)。而惯性(xing)(xing)振(zhen)(zhen)(zhen)(zhen)动(dong)(dong)(dong)(dong)筛由于激振(zhen)(zhen)(zhen)(zhen)器的(de)结构简单(dan),工作可靠(kao)(kao),便(bian)于维(wei)修,从而得到了广泛的(de)使用。惯性(xing)(xing)振(zhen)(zhen)(zhen)(zhen)动(dong)(dong)(dong)(dong)筛是靠(kao)(kao)固(gu)定在其中部的(de)带(dai)偏心块的(de)惯性(xing)(xing)振(zhen)(zhen)(zhen)(zhen)动(dong)(dong)(dong)(dong)器驱动(dong)(dong)(dong)(dong)而使筛箱产生振(zhen)(zhen)(zhen)(zhen)动(dong)(dong)(dong)(dong)。惯性(xing)(xing)振(zhen)(zhen)(zhen)(zhen)动(dong)(dong)(dong)(dong)筛按振(zhen)(zhen)(zhen)(zhen)动(dong)(dong)(dong)(dong)器的(de)形式可分为单(dan)轴振(zhen)(zhen)(zhen)(zhen)动(dong)(dong)(dong)(dong)筛和双轴振(zhen)(zhen)(zhen)(zhen)动(dong)(dong)(dong)(dong)筛。


  振(zhen)(zhen)(zhen)动(dong)(dong)(dong)(dong)筛(shai)(shai)(shai)(shai)按筛(shai)(shai)(shai)(shai)面工作时运(yun)(yun)(yun)动(dong)(dong)(dong)(dong)轨(gui)迹的特点(dian),分为(wei)圆运(yun)(yun)(yun)动(dong)(dong)(dong)(dong)振(zhen)(zhen)(zhen)动(dong)(dong)(dong)(dong)筛(shai)(shai)(shai)(shai)(简(jian)称(cheng)(cheng)圆振(zhen)(zhen)(zhen)动(dong)(dong)(dong)(dong)筛(shai)(shai)(shai)(shai))和直(zhi)(zhi)线运(yun)(yun)(yun)动(dong)(dong)(dong)(dong)振(zhen)(zhen)(zhen)动(dong)(dong)(dong)(dong)筛(shai)(shai)(shai)(shai)(简(jian)称(cheng)(cheng)直(zhi)(zhi)线振(zhen)(zhen)(zhen)动(dong)(dong)(dong)(dong)筛(shai)(shai)(shai)(shai))两(liang)大(da)类(lei)。圆振(zhen)(zhen)(zhen)动(dong)(dong)(dong)(dong)筛(shai)(shai)(shai)(shai)由(you)于振(zhen)(zhen)(zhen)动(dong)(dong)(dong)(dong)器安装的位(wei)置(zhi)偏差,实际筛(shai)(shai)(shai)(shai)箱运(yun)(yun)(yun)动(dong)(dong)(dong)(dong)轨(gui)迹一(yi)般为(wei)椭圆。即使(shi)直(zhi)(zhi)线振(zhen)(zhen)(zhen)动(dong)(dong)(dong)(dong)筛(shai)(shai)(shai)(shai),由(you)于制造与设计偏差,通常(chang)筛(shai)(shai)(shai)(shai)箱的运(yun)(yun)(yun)动(dong)(dong)(dong)(dong)轨(gui)迹也不完全是直(zhi)(zhi)线,只是接(jie)近直(zhi)(zhi)线振(zhen)(zhen)(zhen)动(dong)(dong)(dong)(dong)。圆振(zhen)(zhen)(zhen)动(dong)(dong)(dong)(dong)筛(shai)(shai)(shai)(shai)由(you)于激振(zhen)(zhen)(zhen)器是一(yi)根轴(zhou),所以(yi)又叫(jiao)单轴(zhou)振(zhen)(zhen)(zhen)动(dong)(dong)(dong)(dong)筛(shai)(shai)(shai)(shai),直(zhi)(zhi)线振(zhen)(zhen)(zhen)动(dong)(dong)(dong)(dong)筛(shai)(shai)(shai)(shai)激振(zhen)(zhen)(zhen)器由(you)两(liang)根轴(zhou)组成(cheng),所以(yi)也称(cheng)(cheng)双轴(zhou)振(zhen)(zhen)(zhen)动(dong)(dong)(dong)(dong)筛(shai)(shai)(shai)(shai)。

  当然振(zhen)(zhen)(zhen)动(dong)(dong)(dong)筛(shai)(shai)还有(you)其其他许多分类方(fang)法,例(li)如,按(an)(an)照支撑弹簧的结构(gou)不(bu)同(tong),又有(you)线形弹簧振(zhen)(zhen)(zhen)动(dong)(dong)(dong)筛(shai)(shai)和非线形弹簧振(zhen)(zhen)(zhen)动(dong)(dong)(dong)筛(shai)(shai)。按(an)(an)支承装(zhuang)置(zhi)安装(zhuang)位置(zhi)不(bu)同(tong),可分为(wei)座式(shi)振(zhen)(zhen)(zhen)动(dong)(dong)(dong)筛(shai)(shai)和吊式(shi)振(zhen)(zhen)(zhen)动(dong)(dong)(dong)筛(shai)(shai),按(an)(an)筛(shai)(shai)箱与水(shui)平面是(shi)否成角度安装(zhuang),可分为(wei)水(shui)平筛(shai)(shai)和倾斜筛(shai)(shai)。按(an)(an)工作(zuo)频(pin)(pin)率的高(gao)低(di),可分为(wei)高(gao)频(pin)(pin)振(zhen)(zhen)(zhen)动(dong)(dong)(dong)筛(shai)(shai)和低(di)频(pin)(pin)振(zhen)(zhen)(zhen)动(dong)(dong)(dong)筛(shai)(shai)等(deng)等(deng)。
