在升降貨梯http://www.jntr168.com/更換活塞環(huán)時，如果將環(huán)錯入在氣缸磨損最大的上部進(jìn)行開口間隙的檢查，或根本就沒有按規(guī)定的開口間隙數(shù)值銼削，這樣當(dāng)活塞環(huán)下行到氣缸套下部磨損最小部位時或因受熱膨脹，開口間隙消失而脹死，使環(huán)緊壓在氣缸套的內(nèi)壁上動，導(dǎo)致折斷。由于在氣缸套磨損后氣缸內(nèi)徑不等的情況下，活塞環(huán)除了承受活塞進(jìn)行往復(fù)運(yùn)動外，它自身還在環(huán)槽內(nèi)作一張一合的運(yùn)動，從而使環(huán)與環(huán)槽的上下平面磨損加劇。
When cargo lifter replacement rings, if the ring into the cylinder wear the biggest mistake of the upper part of the inspection opening gap, or simply do not have the required numerical aperture gap cutting and filing, so that when the piston ring down to the lower part of the cylinder liner wear minimal or due to thermal expansion, opening gaps disappear and die swell, so that the ring is pressed against the inner wall of the cylinder liner move, causing broken. Because in the case of the cylinder bore cylinder liner wear after ranging, piston rings in addition to withstand the piston reciprocates, but it still ring groove itself as one of a movement, so that the upper and lower planar ring and ring groove wear and tear.
       
一般情況下，升降貨梯http://www.jntr168.com/活塞環(huán)質(zhì)量太差，活塞環(huán)開口間隙過小，舊氣缸換新環(huán)后第一道氣環(huán)撞擊缸套臺肩，裝配時活塞環(huán)開口擴(kuò)展得過大及缸內(nèi)積炭嚴(yán)重都會導(dǎo)致內(nèi)活塞環(huán)折斷。
Under normal circumstances, the poor quality of cargo lifter piston rings, piston ring opening gap is too small, the old cylinder renewal after the first ring ring shoulder hit liner, piston rings and cylinder openings extend too large coke assembly will result in severe broken piston ring.
