礦用振動篩在礦業(ye)生產中有著舉足輕重旳(di)地位，對其檢查(cha)與維護(hu)也(ye)有著嚴格旳(di)要求與規范，筆(bi)者根據多(duo)年(nian)從業(ye)經(jing)驗(yan)，特總結如下
1、振動篩日(ri)常維護
振動篩(shai)日常維(wei)護(hu)內容包括篩(shai)子表(biao)面(mian)，振動篩(shai)特(te)別是篩(shai)面(mian)緊(jin)固情況，振動篩(shai)松動時應及時緊(jin)固。振動篩(shai)定期清(qing)洗(xi)篩(shai)子表(biao)面(mian)，振動篩(shai)對于(yu)漆皮脫落部位應及時修理(li)、除銹并涂漆，對于(yu)裸露的加工表(biao)面(mian)應涂以工業凡士林以防(fang)生(sheng)銹。
2、振動(dong)篩定期(qi)檢查(cha)
振動篩定期檢(jian)查包括周檢(jian)和月檢(jian)。
(1)、振動(dong)(dong)(dong)(dong)篩(shai)周(zhou)檢(jian)：檢(jian)查(cha)(cha)(cha)激振器、篩(shai)面(mian)、支承裝(zhuang)置等各(ge)部(bu)螺栓緊(jin)(jin)(jin)固(gu)情況，振動(dong)(dong)(dong)(dong)篩(shai)當(dang)有松動(dong)(dong)(dong)(dong)時(shi)應加以緊(jin)(jin)(jin)固(gu)。檢(jian)查(cha)(cha)(cha)傳動(dong)(dong)(dong)(dong)裝(zhuang)置的使用(yong)狀(zhuang)況和連接螺栓的鎖緊(jin)(jin)(jin)情況，振動(dong)(dong)(dong)(dong)篩(shai)檢(jian)查(cha)(cha)(cha)三角帶張緊(jin)(jin)(jin)程度，必要時(shi)適當(dang)張緊(jin)(jin)(jin)。振動(dong)(dong)(dong)(dong)篩(shai)檢(jian)查(cha)(cha)(cha)篩(shai)子時(shi)，振動(dong)(dong)(dong)(dong)篩(shai)須特別(bie)注意查(cha)(cha)(cha)看在飛輪(lun)上的不(bu)平衡(heng)重塊固(gu)定得是否可靠，如固(gu)定不(bu)牢，篩(shai)子運轉時(shi)，振動(dong)(dong)(dong)(dong)篩(shai)不(bu)平衡(heng)重塊就可能脫離飛輪(lun)，導致安全事故(gu)。
(2)、振(zhen)(zhen)動(dong)篩(shai)月檢(jian)(jian)(jian)：檢(jian)(jian)(jian)查(cha)篩(shai)面磨損情況(kuang)，振(zhen)(zhen)動(dong)篩(shai)如發現明顯的局(ju)部(bu)磨損應(ying)采取必要的措施(shi)(如調換(huan)位置等)，并重新(xin)緊固篩(shai)面。振(zhen)(zhen)動(dong)篩(shai)檢(jian)(jian)(jian)查(cha)整個篩(shai)框，振(zhen)(zhen)動(dong)篩(shai)主(zhu)要檢(jian)(jian)(jian)查(cha)主(zhu)梁和全(quan)部(bu)橫(heng)梁焊縫情況(kuang)，振(zhen)(zhen)動(dong)篩(shai)并仔細檢(jian)(jian)(jian)查(cha)是(shi)否有(you)局(ju)部(bu)裂紋。檢(jian)(jian)(jian)查(cha)篩(shai)箱(xiang)側(ce)板全(quan)部(bu)螺栓(shuan)情況(kuang)，振(zhen)(zhen)動(dong)篩(shai)當發現螺栓(shuan)與(yu)側(ce)板有(you)間(jian)隙(xi)或松動(dong)時，振(zhen)(zhen)動(dong)篩(shai)應(ying)更換(huan)新(xin)的螺栓(shuan)。
3、振(zhen)動篩修理
對振(zhen)動(dong)(dong)(dong)篩(shai)(shai)(shai)篩(shai)(shai)(shai)子進(jin)(jin)行(xing)定期(qi)檢查時所發現的(de)問題，振(zhen)動(dong)(dong)(dong)篩(shai)(shai)(shai)應進(jin)(jin)行(xing)修(xiu)(xiu)理(li)。振(zhen)動(dong)(dong)(dong)篩(shai)(shai)(shai)修(xiu)(xiu)理(li)內(nei)容(rong)包括及(ji)時調整三角帶拉(la)力(li)，更(geng)換(huan)(huan)新(xin)帶，更(geng)換(huan)(huan)磨損(sun)的(de)篩(shai)(shai)(shai)面以及(ji)縱向墊條(tiao)，更(geng)換(huan)(huan)減振(zhen)彈簧，更(geng)換(huan)(huan)滾動(dong)(dong)(dong)軸(zhou)承、傳動(dong)(dong)(dong)齒輪和(he)密(mi)封，更(geng)換(huan)(huan)損(sun)壞的(de)螺栓，修(xiu)(xiu)理(li)篩(shai)(shai)(shai)框構件的(de)破損(sun)等。
篩(shai)框側板及(ji)梁應(ying)(ying)避免發生應(ying)(ying)力集中，振(zhen)動篩(shai)因此不(bu)允(yun)許在(zai)這些構件上施以焊接。振(zhen)動篩(shai)對于下(xia)橫梁開裂應(ying)(ying)及(ji)時更換，側板發現裂紋(wen)損(sun)傷時，應(ying)(ying)在(zai)裂紋(wen)盡頭及(ji)時鉆5mm孔(kong)，然后在(zai)開裂部位加補強板。激(ji)振(zhen)器的拆卸、修理和裝配應(ying)(ying)由專職(zhi)人員在(zai)潔凈場所(suo)進(jin)行。
振(zhen)(zhen)(zhen)動篩拆卸(xie)后檢(jian)查(cha)滾動軸承磨損情況(kuang)，振(zhen)(zhen)(zhen)動篩檢(jian)查(cha)齒(chi)(chi)輪齒(chi)(chi)面(mian)，振(zhen)(zhen)(zhen)動篩檢(jian)查(cha)各(ge)部件聯接情況(kuang)，振(zhen)(zhen)(zhen)動篩清洗箱體中的(de)潤滑(hua)回路使之暢通(tong)，振(zhen)(zhen)(zhen)動篩清除(chu)各(ge)結合面(mian)上的(de)附著物，振(zhen)(zhen)(zhen)動篩更(geng)換全部密封件及其(qi)他損壞零件。
振動篩維修時應特(te)別(bie)注意：
(1)激振(zhen)器及傳動(dong)裝置拆卸應(ying)(ying)由有經(jing)驗的技術工人進行，振(zhen)動(dong)篩(shai)(shai)嚴禁野蠻操作，振(zhen)動(dong)篩(shai)(shai)防止損(sun)壞設備。振(zhen)動(dong)篩(shai)(shai)裝配前應(ying)(ying)保持(chi)零件潔凈。
(2)振(zhen)動(dong)篩(shai)更換后的(de)新篩(shai)網應(ying)每隔4-8h重新張緊一次(ci)，振(zhen)動(dong)篩(shai)直到完全張緊為止。
