气动液压泵

气动液压泵

Pneumatic Driven Liquid Pumps

  • 工作原理:利用在两个独立腔体内端面积不同的大小活塞(柱塞)运动,通过力的平衡原理,在低压腔给大面积活塞施加小的压力,高压腔内小面积活塞(柱塞)便能输出大的压力。面积比越大的泵输出的压力越高;
  • 输出压力计算公式:输出压力=驱动气体压力×压力比(大小活塞面积比);
  • 通过压缩空气驱动,调节压缩空气压力即可改变输出压力;调节压缩空气的流量可以改变气动增压泵的动作频率,从而改变输出流量的大小;
  • 输出压力与驱动压力成线性比例关系,容易实现控制操作;
  • 当达到设定输出压力,大小活塞达到里的平衡,增压泵停止工作,此时不再消耗能量,也没有任何热量产生,具有良好的压力保持特性,当有压力泄漏时,增压泵自动补充压力,频繁启动无任何影响;
  • 气动增压泵体积小,结构紧凑,便于安装,便于自动化控制,无需润滑,无需专人专职维护性及耐用性;
  • 因其不需要用电,无火花产生,适合煤矿、石油石化、化工等防爆场合。


  • 气动液压泵典型应用
  • 液压机具如螺栓拉伸器、液压螺母、液压千斤顶等的动力源;
  • 无键连接如大型联轴器、船用舵机、螺旋桨、机车车轮、齿轮、轴承的液压拆装压;
  • 阀门、管道及容器等的压力和爆破试验;
  • 液压胀管及钢管自增强试验卸;
  • 液压夹具、举升、阀门的开启控制及压力机过载保护;装
  • 超高压色谱装柱机。
