第三章齿轮泵齿轮泵在液压传动系统中是最常用的一种类型。齿轮泵的机构比较简单但却是精密的,有两个运动部件:即主动和被动齿轮。齿轮泵的价格,按其功率容量来说是比较低的。现代的齿轮泵能够在2000磅/时~2的压力下有效地运转,有的型号还可以高至4000磅/时~2。容量范围从1加仑/分直到大于100加仑/分。在这样的装置中,它连续地将流体由进口送到出口,而并不需要作往复运动的部件或伐。所以,输出量是随运转速度而变的。
The third chapter gear pump gear pump in the hydraulic transmission system is the most commonly used type. Gear pump mechanism is relatively simple but it is sophisticated, with two moving parts: the active and passive gears. Gear pump price, according to its power capacity is relatively low. Modern gear pumps can operate effectively at pressures from 2000 lbs / h to 2 hrs and some as high as 4,000 lbs / h2. Capacity ranges from 1 gallon / minute up to over 100 gallons / minute. In such a device, it continuously delivers fluid from the inlet to the outlet without the need for reciprocating parts or cutting. Therefore, the output is changed with the speed of operation.
