REXROTH柱塞泵對(duì)于自吸高壓泵應(yīng)盡可能放置在通風(fēng)較好的地方運(yùn)行,以利于快速散熱,降低電機(jī)溫度。否則,長(zhǎng)時(shí)間運(yùn)行,極易燒毀電機(jī)。如某農(nóng)戶在使用自吸高壓泵時(shí),由于沒(méi)有拿掉覆蓋在電機(jī)上塑料薄膜,致使電機(jī)過(guò)熱,燒壞了線圈。另外,在啟動(dòng)前,一定要檢查高壓泵體內(nèi)的存水量,否則,不僅影響自吸性能,而且易燒毀軸封部件。在正常情況下,高壓泵啟動(dòng)后3~5分鐘即應(yīng)出水,否則應(yīng)立即停機(jī)檢查。應(yīng)及時(shí)將高壓泵提離水源,并排空高壓泵內(nèi)積水,尤其在寒冷的冬季。力士樂(lè)REXROTH柱塞泵然后將其放置干燥處,有條件的用戶也可以在高壓泵的重點(diǎn)部位涂上黃油,在軸承內(nèi)加上潤(rùn)滑油,以防零部件銹蝕。另外,高壓泵的非使用期,并非越長(zhǎng)越好。如果長(zhǎng)時(shí)間不使用,不但極易銹蝕零部件,還會(huì)減少高壓泵的使用壽命。
進(jìn)油過(guò)程
當(dāng)凸輪的凸起部分轉(zhuǎn)過(guò)去后,在彈簧力的作用下,柱塞向下運(yùn)動(dòng),柱塞上部空間(稱為泵油室)產(chǎn)生真空度,當(dāng)柱塞上端面把柱塞套上的進(jìn)油孔打開(kāi)后,充滿在油泵上體油道內(nèi)的柴油經(jīng)油孔進(jìn)入泵油室,柱塞運(yùn)動(dòng)到下止點(diǎn),進(jìn)油結(jié)束
回油過(guò)程
柱塞向上供油,當(dāng)上行到柱塞上的斜槽(停供邊)與套筒上的回油孔相通時(shí),泵油室低壓油路便與柱塞頭部的中孔和徑向孔及斜槽溝通,油壓驟然下降,出油閥在彈簧力的作用下迅速關(guān)閉,停止供油。此后柱塞還要上行,當(dāng)凸輪的凸起部分轉(zhuǎn)過(guò)去后,在彈簧的作用下,柱塞又下行。此時(shí)便開(kāi)始了下一個(gè)循環(huán)。
柱塞泵以一個(gè)柱塞為原理介紹,一個(gè)柱塞泵上有兩個(gè)單向閥,并且方向相反,柱塞向一個(gè)方向運(yùn)動(dòng)時(shí)缸內(nèi)出現(xiàn)負(fù)壓,這時(shí)一個(gè)單向閥打開(kāi)液體被吸入缸內(nèi),柱塞向另一個(gè)方向運(yùn)動(dòng)時(shí),將液體壓縮后另一個(gè)單向閥被打開(kāi),被吸入缸內(nèi)的液體被排出。這種工作方式連續(xù)運(yùn)動(dòng)后就形成了連續(xù)供油 。
1)斜盤(pán)式軸向柱塞變量泵,用于開(kāi)式液壓轉(zhuǎn)動(dòng)回路
2)主要用于行走機(jī)械領(lǐng)域
3)泵在自吸條件下,郵箱加壓或帶內(nèi)置吸油泵,(離心泵)的條件下工作
4)輸出流量和驅(qū)動(dòng)轉(zhuǎn)速成比例,并可在值和零值之間無(wú)級(jí)變化
5)多種控制,滿足不同操作要求
6)即使泵在運(yùn)行時(shí)也可在外部來(lái)調(diào)節(jié)功率控制
7)泵系列柱塞泵帶有同軸驅(qū)動(dòng),可與齒輪泵和到相同規(guī)格的軸向柱塞泵串接,以實(shí)現(xiàn)通軸驅(qū)動(dòng)
