液壓泵(尤其是高壓液壓泵)發(fā)出的噪音和/或震動(dòng)達(dá)到了某些新應(yīng)用環(huán)境難以接受的程度。這就是為什么 Settima 要設(shè)計(jì)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(shè)備噪音排放的參數(shù):
- 氣蝕
- 流體從齒輪齒之間通過(guò)時(shí)產(chǎn)生的壓力峰值
- 波動(dòng)或流量脈動(dòng)
Continuum®(低噪音齒輪泵)能夠消除這些引起噪音的因素。
無(wú)噪音 CONTINUUM® 理念
zuan利(多項(xiàng)已獲批或正待批準(zhǔn)的zuan利):
- 轉(zhuǎn)子外形
- 螺距
- 內(nèi)力平衡
專(zhuān)門(mén)研究出的轉(zhuǎn)子外形確保不會(huì)影響流體的體積(沒(méi)有封裝室)。
Continuum® 轉(zhuǎn)子外形的螺旋體(轉(zhuǎn)子之間只有一個(gè)接觸點(diǎn))確保平緩地輸送流體,使脈動(dòng)小化。內(nèi)部安裝了靜液壓機(jī)構(gòu),避免影響效率。
創(chuàng)新的內(nèi)部結(jié)構(gòu)
脈動(dòng)是有害的
- 在軟管和管道設(shè)計(jì)中,壓力脈動(dòng)重要的;因?yàn)閴毫γ}動(dòng)影響液壓系統(tǒng)的使用壽命。
- 噪音不僅是由泵機(jī)自身產(chǎn)生的,在很多情況下,隨著脈動(dòng)增強(qiáng)系統(tǒng)也會(huì)產(chǎn)生噪音。隨之而來(lái)的壓降在顯著消耗能量的同時(shí),還會(huì)降低總效率。
Continuum® 泵是避免系統(tǒng)脈動(dòng)引起的各類(lèi)問(wèn)題的理想選擇。內(nèi)部轉(zhuǎn)子的特殊設(shè)計(jì)消除了氣蝕和脈動(dòng),確保泵機(jī)和系統(tǒng)無(wú)噪音,使用壽命長(zhǎng),同時(shí)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(shí)現(xiàn)了較高的容積效率。
