升降货梯油泵漏油主要是油泵运行时间长，应该立即更换相应的密封圈。升降货梯油泵噪声大主要有以下几方面的原因，希望对大家有所帮助。

1、升降货梯http://www.jntr168.com/系统内不密封，使液压油内吸入大量空气，使油泵噪声增大，如油泵端盖没有把紧，或吸油管没有拧紧等。
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、升降货梯http://www.jntr168.com/油泵电机的联轴器间隙投有调好，基本在1-1.5mm 左右，油泵、电机不在同一轴线上，也会发出异常噪声。
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、升降货梯http://www.jntr168.com/油泵吸油口的网式滤油器被堵，使吸油阻力加人，而导致噪声加大。
Cargo lifter pump inlet filter blocked the net, so that the suction resistance is added, resulting in increased noise.
