水環(huan)真空(kong)(kong)泵是(shi)工廠的(de)常(chang)用設備(bei)(bei)。當時(shi)間(jian)(jian)較長(chang)時(shi),出現(xian)(xian)比問題(ti)大(da)(da)(da)得多(duo)。其斷裂(lie)(lie)(lie)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)問題(ti)通常(chang)為發(fa)(fa)(fa)(fa)(fa)生。許多(duo)人不(bu)明白為什(shen)么(me)會這(zhe)樣,所以讓(rang)我(wo)們來(lai)介紹一(yi)下設備(bei)(bei)的(de)斷軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)原因。 1.水環(huan)真空(kong)(kong)泵發(fa)(fa)(fa)(fa)(fa)動(dong)(dong)機(ji)(ji)(ji)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)的(de)端(duan)部間(jian)(jian)隙過(guo)(guo)大(da)(da)(da)或(huo)(huo)嚴重(zhong)燒(shao)蝕,發(fa)(fa)(fa)(fa)(fa)動(dong)(dong)機(ji)(ji)(ji)在運(yun)行(xing)過(guo)(guo)程中前(qian)后(hou)(hou)(hou)移動(dong)(dong)。 2.主(zhu)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)承(cheng)已經松動(dong)(dong)和(he)磨損太久了(le)(le)。斷裂(lie)(lie)(lie)發(fa)(fa)(fa)(fa)(fa)生在發(fa)(fa)(fa)(fa)(fa)動(dong)(dong)機(ji)(ji)(ji)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)的(de)后(hou)(hou)(hou)半(ban)部分(fen)。這(zhe)也是(shi)由于(yu)發(fa)(fa)(fa)(fa)(fa)動(dong)(dong)機(ji)(ji)(ji)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)頻繁(fan)徑(jing)(jing)向(xiang)(xiang)跳動(dong)(dong),導(dao)致發(fa)(fa)(fa)(fa)(fa)動(dong)(dong)機(ji)(ji)(ji)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)斷裂(lie)(lie)(lie)。 3.軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)端(duan)的(de)推力(li)面位(wei)于(yu)主(zhu)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)上(shang)。同時(shi),發(fa)(fa)(fa)(fa)(fa)動(dong)(dong)機(ji)(ji)(ji)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)也有空(kong)(kong)氣壓(ya)縮(suo)機(ji)(ji)(ji)的(de)負載(zai)。當空(kong)(kong)氣壓(ya)縮(suo)機(ji)(ji)(ji)的(de)負載(zai)增加時(shi),很容易燒(shao)蝕或(huo)(huo)松開發(fa)(fa)(fa)(fa)(fa)動(dong)(dong)機(ji)(ji)(ji)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)并產生徑(jing)(jing)向(xiang)(xiang)跳動(dong)(dong)。 4.如果(guo)主(zhu)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)承(cheng)和(he)連桿軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)承(cheng)多(duo)次(ci)燒(shao)蝕,燒(shao)蝕部分(fen)的(de)支(zhi)撐力(li)減(jian)弱(ruo),軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)的(de)徑(jing)(jing)向(xiang)(xiang)跳動(dong)(dong)將會頻繁(fan)。此(ci)外,應力(li)發(fa)(fa)(fa)(fa)(fa)生在根部消(xiao)融后(hou)(hou)(hou)發(fa)(fa)(fa)(fa)(fa)生變(bian)化,因此(ci)斷裂(lie)(lie)(lie)發(fa)(fa)(fa)(fa)(fa)生位(wei)于(yu)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)的(de)根部和(he)臂之(zhi)間(jian)(jian)。 5.相(xiang)鄰主(zhu)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)承(cheng)之(zhi)間(jian)(jian)的(de)間(jian)(jian)隙過(guo)(guo)大(da)(da)(da),尤(you)其是(shi)后(hou)(hou)(hou)兩(liang)個(ge)(ge)主(zhu)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)承(cheng)和(he)前(qian)兩(liang)個(ge)(ge)主(zhu)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)承(cheng)之(zhi)間(jian)(jian)的(de)間(jian)(jian)隙過(guo)(guo)大(da)(da)(da)。發(fa)(fa)(fa)(fa)(fa)動(dong)(dong)機(ji)(ji)(ji)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)后(hou)(hou)(hou)面有一(yi)個(ge)(ge)飛輪,發(fa)(fa)(fa)(fa)(fa)動(dong)(dong)機(ji)(ji)(ji)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)前(qian)面有一(yi)個(ge)(ge)皮帶輪。當發(fa)(fa)(fa)(fa)(fa)動(dong)(dong)機(ji)(ji)(ji)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)兩(liang)端(duan)受到(dao)(dao)應力(li)過(guo)(guo)重(zhong)時(shi),徑(jing)(jing)向(xiang)(xiang)跳動(dong)(dong)頻繁(fan)。 6、水環(huan)真空(kong)(kong)泵軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)彎曲量(liang)過(guo)(guo)大(da)(da)(da)或(huo)(huo)中心(xin)不(bu)同,且主(zhu)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)承(cheng)間(jian)(jian)隙因彈性不(bu)均(jun)勻,阻礙了(le)(le)發(fa)(fa)(fa)(fa)(fa)動(dong)(dong)機(ji)(ji)(ji)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)的(de)轉動(dong)(dong),加上(shang)發(fa)(fa)(fa)(fa)(fa)動(dong)(dong)機(ji)(ji)(ji)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)前(qian)后(hou)(hou)(hou)載(zai)荷不(bu)均(jun)勻,徑(jing)(jing)向(xiang)(xiang)跳動(dong)(dong)頻繁(fan)。 7.最(zui)終主(zhu)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)承(cheng)燒(shao)蝕或(huo)(huo)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)承(cheng)滾動(dong)(dong)將導(dao)致發(fa)(fa)(fa)(fa)(fa)動(dong)(dong)機(ji)(ji)(ji)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)后(hou)(hou)(hou)部跳動(dong)(dong)過(guo)(guo)大(da)(da)(da)。 水環(huan)真空(kong)(kong)泵運(yun)行(xing)期間(jian)(jian),出現(xian)(xian)的(de)現(xian)(xian)象(xiang)軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)可(ke)能(neng)(neng)會突然斷裂(lie)(lie)(lie)。軸(zhou)(zhou)(zhou)(zhou)(zhou)(zhou)斷裂(lie)(lie)(lie)可(ke)能(neng)(neng)出現(xian)(xian)在表面的(de)發(fa)(fa)(fa)(fa)(fa)生時(shi)刻,但實際上(shang)是(shi)累(lei)積到(dao)(dao)一(yi)定水平程度的(de)定量(liang)變(bian)化和(he)發(fa)(fa)(fa)(fa)(fa)生的(de)定性變(bian)化的(de)結果(guo)。因此(ci),這(zhe)最(zui)終是(shi)缺乏日常(chang)維護和(he)修(xiu)理。我(wo)們應該(gai)把方面做好(hao),減(jian)少(shao)...
