小型振动筛螺栓松动有哪些后果?

有些厂家(jia)往(wang)往(wang)会忽略一个个的小(xiao)细节,出了问(wen)题(ti)才(cai)去检修(xiu)。小(xiao)型振动(dong)筛长时间(jian)工作会造成螺栓松动(dong),这会造成什么后(hou)果(guo)呢?相信很(hen)多人都不(bu)太了解。

日(ri)常的(de)螺栓松动有(you)哪(na)些故障几项(xiang)呢?

日常(chang)小型振动(dong)筛螺栓松动(dong)后(hou),会造(zao)成(cheng)异(yi)常(chang)响声,部件位移(yi)和(he)其(qi)他(ta)故障,一开始螺栓会松动(dong),如果发(fa)现(xian)不及时,会造(zao)成(cheng)脱落,断(duan)裂的严重后(hou)果。

那么如果去防(fang)范振动筛螺栓(shuan)松(song)动呢?

一、规范振动(dong)筛(shai)机械安装和(he)规范调试(shi)。

把(ba)底架的槽钢固定(ding)在(zai)基(ji)础(chu)上,使同(tong)侧前(qian)后支(zhi)承座高度(du)差(cha)一(yi)致,同(tong)一(yi)端(duan)(入料端(duan)或排料端(duan))两(liang)侧的支(zhi)承座板(ban)在(zai)同(tong)一(yi)水(shui)平面内(nei),误差(cha)均在(zai)2mm以内(nei)。

弹(dan)簧在(zai)出厂(chang)前已进行静刚度测试,应选择刚度相同(或相近)的弹(dan)簧配置在(zai)同一台振动(dong)筛的不同支(zhi)承(cheng)位置。安装时把弹(dan)簧置于(yu)下(xia)支(zhi)承(cheng)座上,使支(zhi)承(cheng)座上的凸台进入弹(dan)簧的内(nei)孔上下(xia)均与支(zhi)承(cheng)板的凸台对中,将(jiang)筛板垂(chui)直下(xia)落,置于(yu)弹(dan)簧上。

机(ji)各部(bu)分(fen)连接须(xu)牢固(gu)可靠,所(suo)有(you)螺栓不得有(you)任何(he)松动(dong),各零部(bu)件不得有(you)任何(he)异常声响,筛机(ji)上参(can)振部(bu)分(fen)与周围固(gu)定物之(zhi)间的较小间隙(xi)为30-50mm。

筛机出厂(chang)时,双振(zhen)(zhen)幅调为(wei)5-8mm,用户可调整(zheng)振(zhen)(zhen)动电机的两偏心块间的夹(jia)角(jiao),调整(zheng)激振(zhen)(zhen)力的大(da)小,进而(er)调整(zheng)筛机振(zhen)(zhen)幅的大(da)小。

二、振动筛机械使(shi)用前的空(kong)转测试。

在启动(dong)筛(shai)(shai)机(ji)前,应(ying)检查周(zhou)围是(shi)否有妨碍(ai)筛(shai)(shai)机(ji)运转的障(zhang)碍(ai)物,各处联接螺(luo)栓是(shi)否紧(jin)(jin)固,尤其是(shi)振动(dong)电机(ji)、支承座、筛(shai)(shai)板(ban)的固定螺(luo)栓要重新紧(jin)(jin)固一遍。

检查两(liang)台振动电(dian)机的转向(xiang)是否(fou)相反,如转向(xiang)相同,应变更一台电(dian)机的电(dian)源接线,使两(liang)台振动电(dian)机的转向(xiang)相反。

筛(shai)机运(yun)转时,先(xian)空(kong)(kong)载启动、运(yun)行、停车(che)一次观察有无异常现象及声响(xiang),空(kong)(kong)运(yun)转时应平稳正常。

连续空运转4小(xiao)时后,测(ce)量轴承(cheng)温度,轴承(cheng)温度不得(de)超过75oC;并将各部位联接螺(luo)栓(shuan)重(zhong)新紧固(gu)一次,以(yi)后再反(fan)复进行2-3次

带料运转时,给(ji)料要均(jun)匀(yun),使物(wu)(wu)(wu)(wu)料在筛(shai)面上(shang)均(jun)匀(yun)分布,如物(wu)(wu)(wu)(wu)料“跑偏(pian)”,应调整给(ji)料点。筛(shai)机(ji)(ji)(ji)停(ting)机(ji)(ji)(ji)前,应先停(ting)止给(ji)料,等(deng)筛(shai)面物(wu)(wu)(wu)(wu)料走完后,再停(ting)机(ji)(ji)(ji)。停(ting)机(ji)(ji)(ji)后要及时清理筛(shai)面上(shang)的(de)物(wu)(wu)(wu)(wu)料和杂物(wu)(wu)(wu)(wu)。

三、小型振动筛定(ding)期(qi)检修(xiu) 振动筛定(ding)期(qi)检修(xiu)包括周检和月检。 

(1)振(zhen)动(dong)(dong)筛(shai)(shai)(shai)(shai)周检(jian):检(jian)查激振(zhen)器、筛(shai)(shai)(shai)(shai)面(mian)、支承装置等各部螺栓(shuan)紧(jin)(jin)固(gu)(gu)情况,振(zhen)动(dong)(dong)筛(shai)(shai)(shai)(shai)当有松动(dong)(dong)时应(ying)加以紧(jin)(jin)固(gu)(gu)。检(jian)查传动(dong)(dong)装置的使用状况和(he)连接螺栓(shuan)的锁紧(jin)(jin)情况,振(zhen)动(dong)(dong)筛(shai)(shai)(shai)(shai)检(jian)查三(san)角带张紧(jin)(jin)程度,必要时适当张紧(jin)(jin)。振(zhen)动(dong)(dong)筛(shai)(shai)(shai)(shai)检(jian)查筛(shai)(shai)(shai)(shai)子(zi)时,振(zhen)动(dong)(dong)筛(shai)(shai)(shai)(shai)须特别注(zhu)意查看在飞轮上(shang)的不(bu)平衡(heng)重(zhong)块固(gu)(gu)定得是否(fou)可靠,如固(gu)(gu)定不(bu)牢,筛(shai)(shai)(shai)(shai)子(zi)运(yun)转时,振(zhen)动(dong)(dong)筛(shai)(shai)(shai)(shai)不(bu)平衡(heng)重(zhong)块就可能脱离飞轮,导致(zhi)安全(quan)事故。

(2)振(zhen)动(dong)筛(shai)(shai)(shai)(shai)(shai)月检(jian):检(jian)查(cha)筛(shai)(shai)(shai)(shai)(shai)面磨损情况,振(zhen)动(dong)筛(shai)(shai)(shai)(shai)(shai)如(ru)发现明显的(de)局(ju)部(bu)磨损应采(cai)取(qu)必要的(de)措施(如(ru)调换(huan)位置等(deng)),并重新紧固筛(shai)(shai)(shai)(shai)(shai)面。振(zhen)动(dong)筛(shai)(shai)(shai)(shai)(shai)检(jian)查(cha)整(zheng)个筛(shai)(shai)(shai)(shai)(shai)框,振(zhen)动(dong)筛(shai)(shai)(shai)(shai)(shai)主(zhu)要检(jian)查(cha)主(zhu)梁(liang)和全部(bu)横梁(liang)焊(han)缝情况,振(zhen)动(dong)筛(shai)(shai)(shai)(shai)(shai)并仔细检(jian)查(cha)是否(fou)有(you)局(ju)部(bu)裂纹。检(jian)查(cha)筛(shai)(shai)(shai)(shai)(shai)箱侧板全部(bu)螺栓情况,振(zhen)动(dong)筛(shai)(shai)(shai)(shai)(shai)当发现螺栓与侧板有(you)间隙或松动(dong)时,振(zhen)动(dong)筛(shai)(shai)(shai)(shai)(shai)应更换(huan)新的(de)螺栓。
