升降貨梯油泵漏油主要是油泵運行時間長，應該立即更換相應的密封圈。升降貨梯油泵噪聲大主要有以下幾方面的原因，希望對大家有所幫助。
1、升降貨梯http://m.zjfutures.cn/系統內不密封，使液壓油內吸入大量空氣，使油泵噪聲增大，如油泵端蓋沒有把緊，或吸油管沒有擰緊等。
Within the cargo lifter system is not sealed, so that sucked a lot of air in the hydraulic oil, so that the pump noise increases, such as the oil pump cover did not put tight, or suction pipe not tightened so on.
2、升降貨梯http://m.zjfutures.cn/油泵電機的聯軸器間隙投有調好，基本在1-1.5mm 左右，油泵、電機不在同一軸線上，也會發出異常噪聲。
Cargo lifter pump motor couplings have adjusted the investment gap, basically about 1-1.5mm, pumps, motors are not on the same axis, also an abnormal noise.
3、升降貨梯http://m.zjfutures.cn/油泵吸油口的網式濾油器被堵，使吸油阻力加人，而導致噪聲加大。
Cargo lifter pump inlet filter blocked the net, so that the suction resistance is added, resulting in increased noise.
