礦(kuang)用振動篩在礦(kuang)業生產中(zhong)有著舉(ju)足輕重旳地(di)位(wei)，對其檢查與(yu)維(wei)護也(ye)有著嚴格旳要求與(yu)規(gui)范，筆者根據多年從業經驗(yan)，特總結如(ru)下
1、振動篩日常維護
振(zhen)動篩(shai)日常維護內容包括篩(shai)子表面(mian)，振(zhen)動篩(shai)特別是(shi)篩(shai)面(mian)緊固(gu)情況，振(zhen)動篩(shai)松動時應(ying)及時緊固(gu)。振(zhen)動篩(shai)定(ding)期清(qing)洗(xi)篩(shai)子表面(mian)，振(zhen)動篩(shai)對(dui)(dui)于(yu)漆皮(pi)脫落部(bu)位應(ying)及時修理、除(chu)銹(xiu)(xiu)并涂漆，對(dui)(dui)于(yu)裸露的加工表面(mian)應(ying)涂以工業凡士林以防(fang)生(sheng)銹(xiu)(xiu)。
2、振動篩定期檢查(cha)
振動篩(shai)定期(qi)檢查包括周檢和月檢。
(1)、振動(dong)(dong)(dong)篩周檢(jian)：檢(jian)查(cha)激(ji)振器、篩面、支承裝置(zhi)等各部螺(luo)栓緊固情況，振動(dong)(dong)(dong)篩當有松動(dong)(dong)(dong)時應加(jia)以緊固。檢(jian)查(cha)傳動(dong)(dong)(dong)裝置(zhi)的使(shi)用(yong)狀況和(he)連(lian)接(jie)螺(luo)栓的鎖緊情況，振動(dong)(dong)(dong)篩檢(jian)查(cha)三(san)角帶(dai)張緊程(cheng)度，必(bi)要時適(shi)當張緊。振動(dong)(dong)(dong)篩檢(jian)查(cha)篩子時，振動(dong)(dong)(dong)篩須特別注(zhu)意查(cha)看在飛輪上(shang)的不(bu)平衡重塊(kuai)固定得是否可靠，如固定不(bu)牢(lao)，篩子運轉時，振動(dong)(dong)(dong)篩不(bu)平衡重塊(kuai)就可能脫離飛輪，導(dao)致(zhi)安全事故。
(2)、振(zhen)動(dong)(dong)(dong)(dong)篩(shai)(shai)月檢：檢查(cha)篩(shai)(shai)面磨(mo)損情況(kuang)，振(zhen)動(dong)(dong)(dong)(dong)篩(shai)(shai)如(ru)(ru)發現(xian)明(ming)顯(xian)的(de)局部(bu)磨(mo)損應(ying)采取必要的(de)措施(shi)(如(ru)(ru)調換位(wei)置等)，并重(zhong)新緊固(gu)篩(shai)(shai)面。振(zhen)動(dong)(dong)(dong)(dong)篩(shai)(shai)檢查(cha)整個篩(shai)(shai)框，振(zhen)動(dong)(dong)(dong)(dong)篩(shai)(shai)主要檢查(cha)主梁和全部(bu)橫梁焊縫情況(kuang)，振(zhen)動(dong)(dong)(dong)(dong)篩(shai)(shai)并仔細檢查(cha)是否有局部(bu)裂紋。檢查(cha)篩(shai)(shai)箱側(ce)板(ban)(ban)全部(bu)螺栓(shuan)情況(kuang)，振(zhen)動(dong)(dong)(dong)(dong)篩(shai)(shai)當發現(xian)螺栓(shuan)與(yu)側(ce)板(ban)(ban)有間隙或(huo)松動(dong)(dong)(dong)(dong)時，振(zhen)動(dong)(dong)(dong)(dong)篩(shai)(shai)應(ying)更換新的(de)螺栓(shuan)。
3、振動篩(shai)修(xiu)理
對振動(dong)篩(shai)(shai)(shai)篩(shai)(shai)(shai)子進行(xing)定(ding)期(qi)檢查時(shi)所發現的(de)問題，振動(dong)篩(shai)(shai)(shai)應進行(xing)修(xiu)(xiu)理(li)。振動(dong)篩(shai)(shai)(shai)修(xiu)(xiu)理(li)內(nei)容(rong)包括(kuo)及時(shi)調整三角(jiao)帶(dai)拉力，更(geng)換新帶(dai)，更(geng)換磨損(sun)的(de)篩(shai)(shai)(shai)面以及縱(zong)向墊條，更(geng)換減振彈簧，更(geng)換滾動(dong)軸承、傳動(dong)齒(chi)輪和密封，更(geng)換損(sun)壞的(de)螺(luo)栓，修(xiu)(xiu)理(li)篩(shai)(shai)(shai)框構(gou)件的(de)破損(sun)等。
篩框側板(ban)及(ji)梁應(ying)(ying)避免發(fa)(fa)生應(ying)(ying)力(li)集中，振動篩因此不允許在(zai)這些構件上施以(yi)焊接。振動篩對于(yu)下橫梁開裂應(ying)(ying)及(ji)時(shi)(shi)更換，側板(ban)發(fa)(fa)現裂紋(wen)損傷(shang)時(shi)(shi)，應(ying)(ying)在(zai)裂紋(wen)盡頭及(ji)時(shi)(shi)鉆5mm孔，然后在(zai)開裂部位加補強板(ban)。激(ji)振器的拆卸、修理和裝配應(ying)(ying)由專職(zhi)人員(yuan)在(zai)潔凈場(chang)所(suo)進行。
振(zhen)(zhen)動(dong)(dong)(dong)(dong)篩拆卸(xie)后檢查(cha)滾(gun)動(dong)(dong)(dong)(dong)軸承磨損(sun)情(qing)(qing)況，振(zhen)(zhen)動(dong)(dong)(dong)(dong)篩檢查(cha)齒(chi)輪齒(chi)面(mian)，振(zhen)(zhen)動(dong)(dong)(dong)(dong)篩檢查(cha)各部件(jian)聯接情(qing)(qing)況，振(zhen)(zhen)動(dong)(dong)(dong)(dong)篩清(qing)(qing)洗(xi)箱體(ti)中的潤滑回路使之暢通，振(zhen)(zhen)動(dong)(dong)(dong)(dong)篩清(qing)(qing)除各結合面(mian)上(shang)的附著物，振(zhen)(zhen)動(dong)(dong)(dong)(dong)篩更(geng)換(huan)全部密封件(jian)及其他損(sun)壞零(ling)件(jian)。
振動(dong)篩維修時應特別(bie)注意：
(1)激振(zhen)器及傳動裝置(zhi)拆卸應由(you)有經(jing)驗的技術工人進行，振(zhen)動篩(shai)嚴禁野蠻操作，振(zhen)動篩(shai)防止損(sun)壞設備。振(zhen)動篩(shai)裝配前應保持零件(jian)潔凈。
(2)振動篩(shai)更換后(hou)的新篩(shai)網應每隔4-8h重新張(zhang)緊一次，振動篩(shai)直到完全張(zhang)緊為止。
