3DREM16P-7X/200YG24K4V力士乐减压阀详细介绍

3DREM16P-7X/200YG24K4V德国力士乐减压阀

减压阀是通过调节,将进口压力减至某一需要的出口压力,并依靠介质本身的能量,使出口压力自动保持稳定的阀门。从流体力学的观点看,减压阀是一个局部阻力可以变化的节流元件,即通过改变节流面积,使流速及流体的动能改变,造成不同的压力损失,从而达到减压的目的。然后依靠控制与调节系统的调节,使阀后压力的波动与弹簧力相平衡,使阀后压力在一定的误差范围内保持恒定。排除方法


故障现象:压力波动不稳

故障分析:

1.油液中混入空气2.阻尼孔有时堵塞

3.滑阀与阀体内孔圆度超过规定,使阀卡住

4.弹簧变形或在滑阀中卡住,使滑阀移动困难或弹簧太软

5.钢球不圆,钢球与阀座配合不好或锥阀安装不正确

排除方法:

1.排除油中空气

2.清理阻尼孔

3.修研阀孔及滑阀

4.更换弹簧

5.更换钢球或拆开锥阀调整

故障现象:二次压力升不高

故障分析:

1.外泄漏

2.锥阀与阀座接触不良

排除方法:

1.更换密封件、紧固螺钉,并保证力矩均力

2.修理或更换

故障现象:不起减压力作用

故障分析:

1.泄油口不通;泄油管与回油管相连,并有回油压力

2.主阀芯在全开位置时卡

排除方法:

1.泄油管必须与回油管道分开,单独回入油箱

2.修理、更换零件。检查油质
