雙向齒輪泵的工作原理：
一對相互嚙合的齒輪和泵缸把吸入腔和排出腔隔開。齒輪轉動時，吸入腔側輪齒相互脫開處的齒間容積逐漸增大，壓力降低，液體在壓差作用下進入齒間。隨著齒輪的轉動，一個個齒間的液體被帶至排出腔。這時排出腔側輪齒嚙合處的齒間容積逐漸縮小，而將液體排出。齒輪泵適用于輸送不含固體顆粒，無腐蝕性，粘度范圍較大的潤滑性液體。泵的流量可至300米3/時，壓力可達3×107帕。它通常用作 液壓泵 和輸送各類油品。

The working principle of a bidirectional gear pump:
A pair of meshing gears and pump cylinders separate the suction and discharge chambers. When the gear rotates, the volume between the teeth at the separation point of the suction chamber side teeth gradually increases, the pressure decreases, and the liquid enters the teeth under the pressure difference. As the gears rotate, the liquid between each tooth is carried to the discharge chamber. At this point, the volume between the teeth at the meshing point of the gear teeth on the discharge chamber gradually decreases, and the liquid is discharged. Gear pumps are suitable for conveying lubricating liquids that do not contain solid particles, are non corrosive, and have a wide viscosity range. The flow rate of the pump can reach 300 m3/h, and the pressure can reach 3 × 107 Pa. It is usually used as a hydraulic pump and to transport various types of oil products.
