升降舞臺(tái)液壓泵站故障如何判斷？

1、檢查升降舞臺(tái)http://m.8kvv.com/操縱閥，查看安全閥芯是否已經(jīng)磨損，如果磨損就換新的。在升降舞臺(tái)安全閥安裝后仍然沒有變化，就再檢查操縱閥的閥芯的磨損情況，磨損嚴(yán)重的要換新的。
Check the landing stage control valve to see if the safety valve has been worn, if worn on a new one. After landing stage safety valve installation still does not change, then check for wear on the control valve spool, badly worn to a new one.

2、檢查升降舞臺(tái)http://m.8kvv.com/油缸的內(nèi)漏情況。動(dòng)臂升起，看是否有明顯的自由下落情況，如果升降舞臺(tái)動(dòng)臂下落明顯就要卸下油缸來(lái)檢查，如果密封圈已經(jīng)磨損那就需要更換。
Check the landing stage cylinder internal leakage situation. Boom raised, to see if there is a significant free-fall situation, if the whereabouts of the boom lift stage would obviously remove the fuel tank to check if it has been worn seals need to be replaced.

3、測(cè)量動(dòng)臂液壓泵站的壓力情況，如果壓力偏低，就進(jìn)行適當(dāng)?shù)恼{(diào)整。增加壓力后仍調(diào)不上去，則說(shuō)明液壓泵站損壞非常嚴(yán)重，以及時(shí)更換。
Measuring pressure situation boom pump station, if the pressure is low, the appropriate adjustments. After increasing the pressure is still not tune up, then the damage is very serious pump stations, as well as the replacement.
