href="/supply/25.html" target="_blank">压力?/a></b>——为了使气液增压缸的流量保持稳定,在工作过程中,工作人员就需要通过调速阀的调节作用来实现这一要求。由于减压阀和节流阀之间是有两个液阻存在串联关系,因此在正常情况下,二者之间应保持不得少于0. 5MPa的压差,否则就可能会导致前后压差不稳定?/span><br /> <p> <span style="font-size:16px;font-family:SimSun;">    这样一来,前后压差会处于不停变化的状态,因而系统中的流量也会随着发生变化,后将会导致气液增压缸的速度难以保持稳定。所以,遮掩势必会对整个系统的运行产生一定的负面影响。为了解决这一问题,可以通过提升回路溢流阀的压力,从而使得外负载增大的情况下,调速阀工作点仍然保持在定差O压阀起补偿作用的临界点之内。这样就可以确保执行机构气液增压缸的稳定性?/span> </p> <p style="text-align:center;"> <span style="font-size:16px;font-family:SimSun;"><img src="/uploads/image/20190821/20190821164026_5414.jpg" alt="" /><br /> </span> </p> <span style="font-size:16px;font-family:SimSun;">    有时候我们会发现调速阀是设定在气液增压缸的回油路上,说明该回路属于出口节流调速。其问题表现就是当外负载增大的情况下,执行机构的运行速度会明显降低。很显然,这种情况是和调速阀的使用性能存在很大差异的。气液增压缸生产厂家在将增压缸接入气路前,先将管路及元件内的灰尘等杂物清除,以免降低增压缸的使用寿命。通常情况下,调速阀是用于系统调速。也就是说,其主要是借助一个可以自动调节的可变液阻,来确保另一个固定液阻的前后压差基本不变。所以,这样就可以使得气液增压缸调速阀前后压差可以一直保持稳定?/span><br
