齒輪泵的主要工作部件是互相嚙合的齒輪。互相嚙合的主動齒輪和從動齒輪分別安裝在兩根平行的轉(zhuǎn)軸上，由于輪齒的進(jìn)入和退出嚙合，造成齒間容積的改變形成吸排作用。 葉片泵的主要工作部件是帶有若干可滑動葉片的轉(zhuǎn)子，當(dāng)轉(zhuǎn)子回轉(zhuǎn)時，由于定子內(nèi)腔輪廓線或轉(zhuǎn)子的偏心配置，葉片在葉片槽內(nèi)滑動造成工作容積變化，從而產(chǎn)生吸排作用。 相同之處： 1、都是回轉(zhuǎn)型容積式泵，都具有一定的自吸能力，但都不容許干轉(zhuǎn)； 2、都具有連續(xù)的流量，但也都存在流量和壓力的脈動； 3、理論流量都是由工作部件的尺寸和轉(zhuǎn)速所決定，與排出壓力無關(guān)； 4、額定排出壓力與工作部件尺寸、轉(zhuǎn)速無關(guān)，主要取決于泵的密封性和部件的承受能力； 不同之處： 1）齒輪泵結(jié)構(gòu)更簡單，工作可靠，價格低廉；葉片泵結(jié)構(gòu)較復(fù)雜，零件制造精度要求較高，葉片較易卡住，對油液的清潔程度和粘度更加敏感。 2）無可逆轉(zhuǎn)設(shè)計的齒輪泵也通常可以反轉(zhuǎn)，但反轉(zhuǎn)后吸排口改變，且泵的安全閥不起作用；葉片泵一般不允許反轉(zhuǎn)。 3）單作用葉片泵可以設(shè)計為在不變的轉(zhuǎn)速下通過移動定子改變偏心距，達(dá)到變向變量的目的。
