粉末液壓機日常檢查怎么做發表時(shi)間:2017-05-09 00:00 粉(fen)末液壓機進(jin)行日常檢查就是(shi)為了保證每天都安全運行,一(yi)旦發生故障,日常檢查能有(you)利于判定故障的原因。那么,粉(fen)末液壓機日常檢查怎(zen)么做? 粉末液壓機(ji)日(ri)常檢查有以(yi)下幾(ji)個方面: (1)油(you)(you)(you)箱中油(you)(you)(you)量和(he)溫度(du)。觀察油(you)(you)(you)箱液(ye)(ye)位計(ji),油(you)(you)(you)箱中的(de)液(ye)(ye)面(mian)應經(jing)常保持(chi)正常液(ye)(ye)面(mian),否則要(yao)及時(shi)補充(chong),補充(chong)的(de)油(you)(you)(you)液(ye)(ye)牌號(hao)必須(xu)與系(xi)統的(de)油(you)(you)(you)液(ye)(ye)牌號(hao)相同(tong),并經(jing)化驗,符(fu)合規(gui)定指標;補充(chong)的(de)油(you)(you)(you)液(ye)(ye)要(yao)進行過濾,過濾精(jing)度(du)不低于系(xi)統的(de)精(jing)度(du)要(yao)求。 (2)各密(mi)封(feng)(feng)部位和(he)(he)管接頭等處漏(lou)油(you)情況。液壓系(xi)(xi)統在(zai)工(gong)作(zuo)狀態下(xia)產生泄漏(lou)現象是(shi)不(bu)可避免的,是(shi)常見的。泄漏(lou)導(dao)(dao)致(zhi)系(xi)(xi)統壓力降低(di),導(dao)(dao)致(zhi)執行(xing)元(yuan)件速度不(bu)穩定,浪費油(you)液,消耗能量,降低(di)效率,油(you)溫升高(gao),污染環境(jing),造成火(huo)災隱患。系(xi)(xi)統的泄漏(lou)多發(fa)生在(zai)固定密(mi)封(feng)(feng)和(he)(he)運動密(mi)封(feng)(feng)處。導(dao)(dao)致(zhi)泄漏(lou)的原因通常是(shi)密(mi)封(feng)(feng)件損壞、老化、損傷(shang)或連接螺(luo)釘松動(管路(lu)振動引起的)應及時檢修。非工(gong)作(zuo)狀態下(xia)的泄漏(lou)是(shi)不(bu)允許的。 (3)滋(zi)流閥(fa)和其他壓(ya)(ya)(ya)力(li)(li)閥(fa)壓(ya)(ya)(ya)力(li)(li)調節(jie)處(chu)螺(luo)釘是否松(song)(song)動(dong)(dong)。溢(yi)流閥(fa)調壓(ya)(ya)(ya)螺(luo)釘松(song)(song)動(dong)(dong)將(jiang)導致系統工(gong)作壓(ya)(ya)(ya)力(li)(li)達不(bu)到預定值或建立不(bu)起工(gong)作壓(ya)(ya)(ya)力(li)(li),系統不(bu)能正(zheng)常(chang)工(gong)作。減壓(ya)(ya)(ya)閥(fa)調節(jie)螺(luo)釘松(song)(song)動(dong)(dong)將(jiang)使出口壓(ya)(ya)(ya)力(li)(li)達不(bu)到預定值,使減壓(ya)(ya)(ya)回路不(bu)能正(zheng)常(chang)工(gong)作。 |
