齒輪油泵是用兩個(gè)齒輪互嚙轉(zhuǎn)動來工作，對介質(zhì)要求不高。一般的壓力20MPa以下，

流量較大。 齒輪油泵在泵體中裝有一對回轉(zhuǎn)齒輪，一個(gè)主動，一個(gè)被動，依靠兩齒

輪的相互嚙合，把泵內(nèi)的整個(gè)工作腔分兩個(gè)獨(dú)立的部分。A為吸入腔，B為排出腔。齒

輪油泵在運(yùn)轉(zhuǎn)時(shí)主動齒輪帶動被動齒輪旋轉(zhuǎn)，當(dāng)齒輪從嚙合到脫開時(shí)在吸入側(cè)（A）

就形成局部真空，液體被吸入。被吸入的液體充滿齒輪的各個(gè)齒谷而帶到排出側(cè)（B），

齒輪進(jìn)入嚙合時(shí)液體被擠出，形成高壓液體并經(jīng)泵排出口排出泵外。
