威格士液壓柱塞泵靠氣壓供油的液壓油箱，在每次啟動機器后，必須等液壓漬箱達到使用氣壓后，才能操作機械。直軸斜盤式柱塞泵分為壓力供油型的自吸油型兩種。壓力供油型液壓泵大都采用有氣壓的油箱，也有液壓泵本身帶有補油分泵向液壓泵進油口提供壓力油的。自吸油型液壓泵的自吸油能力很強，無需外力供油。對于自吸油型柱塞泵，液壓油箱內(nèi)的油液不得低于油標下限，要保持足夠數(shù)量的液壓油。液壓油的清潔度越高，液壓泵的使用壽命越長。美國威格士柱塞泵*產(chǎn)品
Vickers威格士柱塞泵的維護
威格士斜盤式軸向柱塞泵一般采用缸體轉動、端面配流的形式。缸體端面上鑲有一塊由雙金屬板與鋼配油盤組成的摩擦副，而且大多數(shù)是采用平面配流的方法，所以維修比較方便。配油盤是軸向柱塞泵的關鍵部件之一，泵工作時，一方面工作腔的高壓油把缸體推向配油盤，另一方面配油盤和缸體間的油膜壓力形成對缸體的液壓反推力使缸體背離配油盤。缸體對配油盤的設計液壓壓緊力Fn略大于配油盤對缸體的液壓反推力Ff，即Fn/Ff=1.05~1.1，使泵工作正常并保持較高的容積效率。 實際上，由于油液的污染，往往使配油盤與缸體之間產(chǎn)生輕微磨損。
Vickers威格士柱塞泵的特點：
Vickers威格士柱塞泵規(guī)格齊全有多達9 種，主要是直軸式變量泵，控制方式多樣化，主要靠壓力來控制變量。提高工作靈活性，提供流量補償。 Vickers威格士柱塞泵運行噪聲很低，能滿足當今要求苛刻的工業(yè)條件。每臺泵的噪聲級接近于或低于驅動該泵電動機的噪聲，噪聲是靠的定時配置來降低的，而該措施還使輸出流量中壓力“脈動"很小。

Vickers威格士柱塞泵是往復泵的一種，屬于體積泵，其柱塞靠泵軸的偏心轉動驅動，往復運動，其吸入和排出閥都是單向閥。當柱塞外拉時，工作室內(nèi)壓力降低，出口閥關閉，低于進口壓力時，進口閥打開，液體進入；柱塞內(nèi)推時，工作室壓力升高，進口閥關閉，高于出口壓力時，出口閥打開，液體排出。帶滑靴結構的軸向柱塞泵是目前使用zui廣泛的軸向柱塞泵，安放在缸體中的柱塞通過滑靴與斜盤相接觸，當傳動軸帶動缸體旋轉時，斜盤將柱塞從缸體中拉出或推回，完成吸排油過程。柱塞與缸孔組成的工作容腔中的油液通過配油盤分別與泵的吸、排油腔相通。變量機構用來改變斜盤的傾角，通過調(diào)節(jié)斜盤的傾角可改變泵的排量。美國威格士柱塞泵*產(chǎn)品
