液壓泵(尤其是高壓液壓泵)發出的噪音和/或震動達到了某些新應用環境難以接受的程度。這就是為什么 Settima 要設計能夠消除噪音排放的新一代齒輪泵的主要原因。
影響液壓設備噪音排放的參數:
- 氣蝕
- 流體從齒輪齒之間通過時產生的壓力峰值
- 波動或流量脈動
Continuum®(低噪音齒輪泵)能夠消除這些引起噪音的因素。
無噪音 CONTINUUM® 理念
zuan利(多項已獲批或正待批準的zuan利):
- 轉子外形
- 螺距
- 內力平衡
專門研究出的轉子外形確保不會影響流體的體積(沒有封裝室)。
Continuum® 轉子外形的螺旋體(轉子之間只有一個接觸點)確保平緩地輸送流體,使脈動小化。內部安裝了靜液壓機構,避免影響效率。
創新的內部結構
脈動是有害的
- 在軟管和管道設計中,壓力脈動重要的;因為壓力脈動影響液壓系統的使用壽命。
- 噪音不僅是由泵機自身產生的,在很多情況下,隨著脈動增強系統也會產生噪音。隨之而來的壓降在顯著消耗能量的同時,還會降低總效率。
Continuum® 泵是避免系統脈動引起的各類問題的理想選擇。內部轉子的特殊設計消除了氣蝕和脈動,確保泵機和系統無噪音,使用壽命長,同時降低了能量損失。
CONTINUUM® 容積效率
Continuum® 泵的容積效率取決于壓力和速度。Continuum® 泵實現了較高的容積效率。
