parker齒輪泵是容積泵的一種，由兩個(gè)齒輪、泵體與前后蓋組成兩個(gè)封閉空間，當(dāng)齒輪轉(zhuǎn)動(dòng)時(shí)，齒輪脫開(kāi)側(cè)的空間的體積從小變大，形成真空，將液體吸入，齒輪嚙合側(cè)的空間的體積從大變小，而將液體擠入管路中去。吸入腔與排出腔是靠?jī)蓚€(gè)齒輪的嚙合線來(lái)隔開(kāi)的。parker齒輪泵的排出口的壓力*取決于泵出處阻力的大小。依靠泵缸與嚙合齒輪間所形成的工作容積變化和移動(dòng)來(lái)輸送液體或使之增壓的回轉(zhuǎn)泵。外嚙合雙齒輪泵的結(jié)構(gòu)。一對(duì)相互嚙合的齒輪和泵缸把吸入腔和排出腔隔開(kāi)。齒輪轉(zhuǎn)動(dòng)時(shí)，吸入腔側(cè)輪齒相互脫開(kāi)處的齒間容積逐漸增大，壓力降低，液體在壓差作用下進(jìn)入齒間。隨著齒輪的轉(zhuǎn)動(dòng)，一個(gè)個(gè)齒間的液體被帶至排出腔。這時(shí)排出腔側(cè)輪齒嚙合處的齒間容積逐漸縮小，而將液體排出。parker齒輪泵適用于輸送不含固體顆粒、無(wú)腐蝕性、粘度范圍較大的潤(rùn)滑性液體。泵的流量可至300m3/時(shí)，壓力可達(dá)3×107帕。它通常用作液壓泵和輸送各類油品。齒輪泵結(jié)構(gòu)簡(jiǎn)單緊湊,制造容易，維護(hù)方便，有自吸能力，但流量、壓力脈動(dòng)較大且噪聲大。parker齒輪泵必須配帶安全閥，以防止由于某種原因如排出管堵塞使泵的出口壓力超過(guò)容許值而損壞泵或原動(dòng)機(jī)。
