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。

我公司在分別在美國華盛頓，德國不萊梅，上海，東莞設立了五家公司。所有產(chǎn)品保證全新*。歡迎各位來我司詢價采購.
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VICKERS威格士柱塞泵是依靠柱塞與缸體內(nèi)孔面來形成密封工作容積的。由于柱塞與缸體內(nèi)孔均為圓柱表面，因此加工方便，配合精度高，密封性能好。故柱塞泵常做成高壓泵。
優(yōu)點：壓力高、結(jié)構緊湊、效率高及流量調(diào)節(jié)方便。
缺點：結(jié)構復雜，價格較貴。
柱塞泵按柱塞排列方向的不同，分為軸向柱塞泵和徑向柱塞泵。在此，簡要介紹軸向柱塞泵和回轉(zhuǎn)式徑向柱塞泵。
