简单介绍
atos叠加式溢流阀型号,阿托斯叠加式溢流阀规格
溢流阀的导阀部分是一个易振部位如图3所示。
在高压情况下溢流时,导阀的轴向开口很小,仅0.003~0.006厘米。
过流面积很小,流速很高,可达200米/秒,易引起压力分布不均匀,
使锥阀径向力不平衡而产生振动。另外锥阀和锥阀座加工时产生的椭圆度、
导阀口的脏物粘住及调压弹簧变形等,也会引起锥阀的振动。

It is generally believed that the pilot valve is the source of noise generated by the source.
When air is drawn into the oil for various reasons,
or when the oil pressure is below atmospheric pressure,
先导式溢流阀调压失灵现象有二种情况:
一种是调节调压手轮建立不起压力,或压力达不到额定数值;
另一种调节手轮压力不下降,甚至不断升压。
出现调压失灵,除阀芯因种种原因造成径向卡紧外,还有下列一些原因
the volume suddenly smaller or bubble disappeared;
On the contrary, as in the high pressure area when the volume was small,
and when the flow to the low pressure area, the volume suddenly increased,
Oil bubbles in the rapid changes in the phenomenon of
this phenomenon. Sudden changes in the volume of the bubble will produce noise,
这是由于溢流阀的卸荷时间很短而产生液压冲击所致在卸荷时,
由于油流速急剧变化,引起压力突变,造成压力波的冲击。
压力波是一个小的冲击波,本身产生的噪声很小,但随油液传到系统中,
如果同任何一个机械零件发生共振,就可能加大振动和增强噪声。
所以在发生液压冲击噪声时,一般多伴有系统振 动。
溢流阀在使用中有时会出现调压失灵现象。
And because this process occurs in an instant,
will cause local hydraulic shock and produce vibration.
The pilot valve and the main valve port of the pilot relief valve,
the oil flow rate and pressure changes greatly,
It is prone to hole phenomenon, resulting in noise and vibration.
The part of the air dissolved in the oil will precipitate the formation of bubbles,
these bubbles in the low pressure area when the larger,
When the oil flow to the high pressure area, the compression,
