气压缸现已广泛应用,可是由于使用的是空气这样一种具有压缩性的工作介质,但要在低速时得到稳定的进给,由于滑动部位的摩擦阻力的变化、负载变化对进给速度产生影响,因而不大容易实现。如果使用液压缸就不同了,它可以对进给速度以超低速到高速进行稳定的无级调节,远远弥补了气压缸的不足。所以有人把液压缸又称为液体速度控制器。在此,介绍一下新开发的不供油,全封闭式的液体速度控制器。
The pneumatic cylinder is now widely used, but due to the use of a compressible working medium such as air, stable feed at low speed is obtained. Due to the change of the frictional resistance of the sliding portion, the change of the load causes an increase in the feed speed Influence, and therefore not easy to achieve. If you use a hydraulic cylinder is different, it can feed speed to ultra-low speed to high-speed stability of the stepless adjustment, far make up for lack of pressure cylinder. So someone called the hydraulic cylinder, also known as the liquid speed controller. Here, introduce the newly developed oil-free, fully enclosed liquid speed controller.
