螺桿泵使用注意事項(xiàng)
下面介紹其它油泵不具備,而螺桿泵所*的特性。
(1)GD,(慣性力矩)小 ,螺桿泵的慣性力矩GDZ非常小。這是由于主動(dòng)螺桿及從動(dòng)螺桿的外徑較小,對(duì)泵不必特別考慮動(dòng)平衡問題。但是,由于電動(dòng)機(jī)和聯(lián)結(jié)器的GD“值為泵的數(shù)倍以上,因而在選定和加工泵時(shí)需充分注意這個(gè)問題。
(2)變頻器驅(qū)動(dòng) 螺桿泵為定容積型泵,所以近來多用變頻器控制泵流量。特別是工藝流程中,采用了Pl及PID控制方式,這樣可獲得準(zhǔn)確的流量.
在用變頻器的場(chǎng)合,用于液壓沒備的螺桿泵所存在的問題是:泵在低速運(yùn)轉(zhuǎn)時(shí)噪聲大。這是因?yàn)樽冾l器產(chǎn)生的輸入電流波形像商用電源那樣不平滑,所以電動(dòng)機(jī)轉(zhuǎn)速發(fā)生變化,致使泵的排出壓力脈功增大。
(3)汽蝕 泵的吸入壓力降低會(huì)產(chǎn)生汽蝕,引起噪聲和振動(dòng)增大.這時(shí)不僅是排出端,吸入端的壓力脈動(dòng)波形也會(huì)大亂,排量隨之減小。如果是液壓用油.泵的吸入壓力可達(dá)0.05a,所以吸入管路很容易滲入空氣。因此在安裝管路和過濾器時(shí)應(yīng)特別注意密封問題。
人們一般不太了解螺桿泵,但實(shí)際上它的用途很廣。今后液壓設(shè)備還要向高壓化發(fā)展,可能使用的液體種類也會(huì)增多,我們期待著螺桿泵的用途進(jìn)一步擴(kuò)大。
