齿轮泵在 WY—100 型履带式单斗液压挖掘机液压系统中的应用摘要齿轮泵的概念是很简单的即它的最基本形式就是两个尺寸相同的齿轮在一个紧密配合的壳体内相互啮合旋转,这个壳体的内部类似“8”字形,两个齿轮装在里面,齿轮的外径及两侧与壳体紧密配合。来自于挤出机的物料在吸入口进入两个齿轮中间,并充满这一空间,随着齿的旋转沿壳体运动,最后在两齿啮合时排出。由于结构简单、价格便宜等优点,得到了广泛应用。关键词:齿轮泵 挖掘机 液压Gear pump in the WY - 100 type crawler type hydraulic excavator hydraulic systemSummaryGear pump concept is very simple : it is the most basic form is two identical gear in a closely intermeshing rotary shell, the shell is similar to the figure "8", the two gear is installed on the inside, outside and two sides of the gear casing closely. From an extruder material in a suction port into the two intermediate gear, and fill this space, with the teeth rotate along the casing movement, finally in two teeth from. Because of the simple structure, cheap price advantage, widely used.Keyword: gear pump excavation hydraulic pressure目录摘要............................................................................................................................................................1第一章 绪论...............................................................................................................................................11.1 齿轮泵简介......................................................................................................................................11.2 齿轮泵的应用..................................................................................................................................31.2.1 泵的进展历史...........................................................................................................................31.2.2 齿轮泵的技术进展趋势............................................................
