    齒輪泵優點：自吸式;排出量恒定且振動很小;可以雙向輸送;由于較小的間隙，流量隨粘度和壓力變化不大。 Advantages of gear pump: self-priming; Constant discharge and the vibration is small; Can be two-way transmission; Due to the small clearance, the flow changing with viscosity and pressure is not big.

    齒輪泵缺點：由于較小的置換容積以及會磨損齒牙，所以只能輸送干凈的流體;不能空轉;由于裝配和定位精度高，所以加工誤差要求很小。 Disadvantages: the gear teeth due to smaller displacement volume and will wear, so can only transport clean fluid;Don't idle;Due to the assembly and high positioning accuracy, so the machining error requirement is very small.
