一、前言变量叶片泵,大多数是定子环相对转子在轴中心上产生偏心,而改变排油量的叶片式油泵,它具有依靠液压回路的负荷压力而自动改变偏心量的独特结构。这种泵仅对回路供给所必需的流量和压力,因而没有无用功的动力损失,油温上升较低,减少动力消耗,所以近来很被重视,尤其是在机床等设备上正在被广泛地采用。 First, the foreword Vane pumps, most of the stator ring is relative to the rotor eccentric center of the shaft, while changing the oil displacement vane pump, it has to rely on the hydraulic circuit pressure load and automatically change the eccentric structure of the unique. This type of pump supplies only the necessary flow and pressure to the circuit, so that there is no power loss of unnecessary work, low rise of oil temperature and reduction of power consumption, so it has recently been taken seriously, especially in machine tools and other equipment.
