做到七大事項延長振動平臺的使用壽命
振(zhen)動平(ping)臺(tai)又叫(jiao)振(zhen)實臺(tai),主要(yao)(yao)用(yong)于物(wu)料的震實,減少物(wu)料內的空氣和縫隙。要(yao)(yao)想延長(chang)振(zhen)動平(ping)臺(tai)的使用(yong)壽(shou)命,除了要(yao)(yao)按時(shi)的保養和維護之外(wai),在平(ping)時(shi)的使用(yong)過程中還要(yao)(yao)注意哪些事(shi)項呢(ni)?今天小(xiao)編就來大家說說這(zhe)個(ge)問題。
應(ying)將(jiang)振(zhen)動平(ping)臺安裝(zhuang)在牢固(gu)的基礎(chu)上(shang),地腳螺栓(shuan)應(ying)有足夠強(qiang)度(du)并(bing)(bing)擰緊(jin)(jin),同時(shi)在基礎(chu)中(zhong)(zhong)間必須(xu)留有地下(xia)坑道,以便經(jing)常調整與維(wei)修。使(shi)用(yong)前要(yao)進行檢(jian)(jian)查(cha)和試(shi)運(yun)轉(zhuan),檢(jian)(jian)查(cha)機件是(shi)否完好(hao)(hao),所有緊(jin)(jin)固(gu)件,特別是(shi)軸(zhou)承(cheng)(cheng)座螺栓(shuan)、偏心塊螺栓(shuan)、電動機和齒(chi)(chi)輪(lun)箱(xiang)(xiang)螺拴等,必須(xu)緊(jin)(jin)固(gu)牢靠。動平(ping)臺不宜空載(zai)(zai)長時(shi)間運(yun)轉(zhuan)。在生產作業(ye)中(zhong)(zhong),必須(xu)安置牢固(gu)可靠的模(mo)板鎖緊(jin)(jin)夾具,以保證模(mo)板和混凝土臺面(mian)一起振(zhen)動。齒(chi)(chi)輪(lun)箱(xiang)(xiang)中(zhong)(zhong)的齒(chi)(chi)輪(lun)因受高速重載(zai)(zai)荷,故應(ying)潤(run)(run)滑和冷(leng)卻良(liang)好(hao)(hao);箱(xiang)(xiang)內油平(ping)應(ying)保持(chi)(chi)在規定的水平(ping)面(mian)上(shang),工作時(shi)溫(wen)升不得超過70oC.振(zhen)動臺所有軸(zhou)承(cheng)(cheng)應(ying)經(jing)常檢(jian)(jian)查(cha)并(bing)(bing)定期(qi)拆(chai)洗(xi)更換潤(run)(run)滑脂,使(shi)軸(zhou)承(cheng)(cheng)潤(run)(run)滑良(liang)好(hao)(hao),并(bing)(bing)應(ying)注(zhu)(zhu)意檢(jian)(jian)查(cha)軸(zhou)承(cheng)(cheng)溫(wen)升當有過熱現象時(shi)應(ying)立即(ji)設法(fa)。電動機接地應(ying)良(liang)好(hao)(hao)可靠,電源線和線接頭應(ying)絕緣良(liang)好(hao)(hao)。不得有破損漏電現象。振(zhen)動臺面(mian)應(ying)經(jing)常保持(chi)(chi)清(qing)潔平(ping)整,以便與鋼(gang)模(mo)接觸(chu)良(liang)好(hao)(hao)。因臺面(mian)在高頻重載(zai)(zai)下(xia)振(zhen)動,容(rong)易產生裂紋,必須(xu)注(zhu)(zhu)意檢(jian)(jian)查(cha),及(ji)時(shi)修補。每班作業(ye)完畢應(ying)及(ji)時(shi)清(qing)洗(xi)干凈(jing)。
振動平(ping)臺(tai)在使(shi)用前雖然廠家在發(fa)(fa)貨時是經(jing)過調(diao)試及各(ge)種檢測以后才發(fa)(fa)給(gei)客戶(hu),振動平(ping)臺(tai)經(jing)過中途運(yun)輸發(fa)(fa)到用戶(hu)公司在使(shi)用前怎樣進行安(an)裝呢(ni)?下(xia)(xia)面振動平(ping)臺(tai)廠家將安(an)裝方法(fa)列舉如下(xia)(xia):
振(zhen)(zhen)(zhen)動(dong)(dong)平臺(tai)進(jin)(jin)行安裝(zhuang)(zhuang)(zhuang)時,基礎接觸面(mian)要(yao)水平,不超過(guo)±0.15;地(di)角(jiao)基礎螺(luo)(luo)栓擰緊(jin)(jin),不得有松(song)動(dong)(dong)現象;檢(jian)查(cha)電(dian)(dian)機(ji)固定(ding)螺(luo)(luo)絲(si)(si)和(he)平臺(tai)緊(jin)(jin)固螺(luo)(luo)絲(si)(si),均不得松(song)動(dong)(dong);待檢(jian)查(cha)安裝(zhuang)(zhuang)(zhuang)無(wu)誤(wu)時,可(ke)進(jin)(jin)行空(kong)載(zai)試車,在空(kong)載(zai)試車無(wu)異常(chang)的(de)(de)情況下,進(jin)(jin)行負載(zai)作業;若需調(diao)整(zheng)振(zhen)(zhen)(zhen)幅(fu),可(ke)先通過(guo)變頻器(qi)調(diao)節,降(jiang)低頻率增大(da)振(zhen)(zhen)(zhen)幅(fu),升高(gao)頻率減振(zhen)(zhen)(zhen)幅(fu),也可(ke)通過(guo)機(ji)械式(shi)調(diao)整(zheng),打開振(zhen)(zhen)(zhen)動(dong)(dong)電(dian)(dian)機(ji)防護罩將每一端的(de)(de)外偏(pian)(pian)心塊(kuai)鎖緊(jin)(jin)螺(luo)(luo)絲(si)(si)松(song)開,調(diao)整(zheng)外偏(pian)(pian)心塊(kuai)和(he)內偏(pian)(pian)心塊(kuai)之間(jian)夾角(jiao)來改(gai)變激振(zhen)(zhen)(zhen)力(li)大(da)小(xiao)從(cong)而調(diao)整(zheng)到(dao)需要(yao)的(de)(de)工作振(zhen)(zhen)(zhen)幅(fu);振(zhen)(zhen)(zhen)動(dong)(dong)電(dian)(dian)機(ji)工作的(de)(de)運(yun)(yun)轉方向,立式(shi)裝(zhuang)(zhuang)(zhuang)為同向運(yun)(yun)轉;臥式(shi)裝(zhuang)(zhuang)(zhuang)為同步反(fan)向運(yun)(yun)轉;在振(zhen)(zhen)(zhen)動(dong)(dong)電(dian)(dian)機(ji)調(diao)整(zheng)好(hao)后,要(yao)裝(zhuang)(zhuang)(zhuang)好(hao)防護罩,確保;要(yao)定(ding)期檢(jian)查(cha)各個(ge)部分的(de)(de)緊(jin)(jin)固螺(luo)(luo)絲(si)(si),檢(jian)查(cha)帶(dai)負荷的(de)(de)箱體與臺(tai)面(mian)的(de)(de)緊(jin)(jin)固情況,以免造成二次(ci)振(zhen)(zhen)(zhen)動(dong)(dong)損壞臺(tai)面(mian)。
