派克齒輪泵

派克齒輪采用具有九十年人*水平的新技術--雙圓弧正弦曲線齒型圓弧。它與漸開線齒輪相比，zui突出的優點是齒輪嚙合過程中齒廓面沒有相對滑動，所以齒面無磨損、運轉平衡、無困液現象，噪聲低、壽命長、效率高。該泵擺脫傳統設計的束縛，使得齒輪泵在設計、生產和使用上進入了一個新的領域。
派克齒輪泵設有差壓式安全閥作為超載保護，安全閥全回流壓力為泵額定排出壓力1.5倍。也可在允許排出壓力范圍內根據實際需要另行調整。但是此安全閥不能作減壓閥長期工作，需要時可在管路上另行安裝。
該齒輪泵泵軸端密封設計為兩種形式，一種是機械密封，另一種是填料密封，可根據具體使用情況和用戶要求確定。
parker齒輪油泵因受定排量的結構限制，通常認為齒輪泵僅能作恒流量液壓源使用。然而，附件及螺紋聯接組合閥方案對于提高其功能、降低系統成本及提高系統可靠性是有效的，因而，齒輪油泵的性能可接近價昂、復雜的柱塞泵。
在泵上直接安裝控制閥，可省去泵與方向閥之間管路，從而控制了成本。較少管件及連接件可減少泄漏，從而提高工作可靠性。而且泵本身安裝閥可降低回路的循環壓力，提高其工作性能。下面是一些可提高齒輪泵基本功能的回路，其中有些是實踐證明可行的基本回路，而有些則屬創新研究。
