油液在液压系统中通常可视为不可压缩的或压缩量甚小,然而随着高压、超高压设备或高精度液压系统的出现,以及在(?)载持续作用下的液压平衡封闭系统中,就不能忽视油液的压缩性。今以精度要求较高的液压平衡封闭系统为例,对其油液的应用进行初步探讨。 Oil can often be considered incompressible or very small in hydraulic systems, but with the advent of high-pressure, ultra-high pressure equipment or high-precision hydraulic systems, as well as hydraulically-balanced closed systems under continuous load , You can not ignore the fluid’s compressibility. Now with high precision hydraulic balance closed system, for example, the application of the oil to conduct a preliminary discussion.
