转载——Star-伺服阀业界拥有蓝宝石技术的星星[0]

Posted on 2023年11月14日 by

Star伺服阀有哪些与众不同之处?

机械反馈杆上采用蓝宝石技术。

许多star的伺服阀在制造进油节流口时使用了蓝宝石,对用户来说,好处是克服了传统节流口的磨损问题,改进了性能,延长了使用寿命。

伺服阀内部结构以及组成原理的介绍。

典型的阀芯在阀套中的移动距离0.5mm。机加工间隙2.5μm。

喷射口间隙0.03mm,喷嘴直径范围0.4~0.66mm。

球的凹槽与蓝宝石之间的间隙为0.25微米。

蓝宝石节流口。

柔性套筒,采用钛材料,超长寿命,使用次数可达亿次以上。

反馈蓝宝石小球,阀芯带槽设计。

1000Hz,还有这么高频率的伺服阀?

1000Hz频率伺服阀应用于测试试验台。

测试台用于动态测试橡胶和金属橡胶元件,具体工况:

油缸行程:20mm

最大载荷:±7000N

正常频率:0~800Hz

最大频率:1000Hz(振幅±0.03mm)

伺服油缸:30×28,静压支撑密封

伺服阀:Star Model 590
