【簡單介紹】
【詳細(xì)說明】
當(dāng)凸輪的凸起部分轉(zhuǎn)過去后,
在彈簧力的作用下,柱塞向下運(yùn)動,
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)動到下止點(diǎn),進(jìn)油結(jié)束

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,
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)過去后,
在彈簧的作用下,柱塞又下行。
此時便開始了下一個循環(huán)。
柱塞泵以一個柱塞為原理介,
一個柱塞泵上有兩個單向閥,
并且方向相反,柱塞向一個方向
運(yùn)動時缸內(nèi)出現(xiàn)負(fù)壓,這時一個
單向閥打開液體被吸入缸內(nèi),
柱塞向另一個方向運(yùn)動時,
將液體壓縮后另一個單向閥被打開,
被吸入缸內(nèi)的液體被排出。
這種工作方式連續(xù)運(yùn)動后就形成了連續(xù)供油 。

柱塞泵zui重要的部件是軸承,
如果軸承出現(xiàn)游隙,則不能
保證液壓泵內(nèi)部三對磨擦副的
正常間隙,同時也會破壞各
磨擦副的靜液壓支承油膜厚度,
降低柱塞泵軸承的使用壽命。
據(jù)液壓泵制造廠提供的資料,
軸承的平均使用壽命為10000h,
超過此值就需要更換新口。
拆卸下來的軸承,沒有專業(yè)
檢測儀器是無法檢測出軸承的
游隙的,只能采用目測,
如發(fā)現(xiàn)滾柱表面有劃痕或變色,
就必須更換

在更換軸承時,應(yīng)注意原軸承
的英文字母和型號,柱塞泵軸承
大都采用大載荷容量軸承,
購買原廠家,原規(guī)格的產(chǎn)品,
如果更換另一種品牌,應(yīng)請教對軸承
有經(jīng)驗(yàn)的人員查表對換,目的是保持
軸承的精度等級和載荷容量。

柱塞泵使用壽命的長短,
與平時的維護(hù)保養(yǎng),
液壓油的數(shù)量和質(zhì)量,
油液清潔度等有關(guān)。
避免油液中的顆粒對
柱塞泵磨擦副造成磨損等,
也是延長柱塞泵壽命的有效途徑。
在維修中更換零件應(yīng)盡量使用原廠
生產(chǎn)的零件,這些零件有時比其它
仿造的零件價格要貴,但質(zhì)量及穩(wěn)定
性要好,如果購買售價便宜的仿造零件,
短期內(nèi)似乎是節(jié)省了費(fèi)用,但由此出帶來
了隱患,也可能對柱塞泵的使用造成更大的危害。
