油量調(diào)節(jié)

為了適應(yīng)柴油機(jī)負(fù)載的要求，噴油泵的供油量必須能夠在大供油量(全負(fù)荷)到零供油量(停車)的范圍內(nèi)進(jìn)行調(diào)節(jié)。 供油量的調(diào)節(jié)是通過(guò)齒桿、轉(zhuǎn)動(dòng)套使噴油泵的全部柱塞同時(shí)轉(zhuǎn)動(dòng)來(lái)實(shí)現(xiàn)的。 當(dāng)柱塞轉(zhuǎn)動(dòng)時(shí)，供油開始時(shí)間不變，而供油終了時(shí)間，則由于柱塞斜邊對(duì)柱塞套回油孔位置的改變而變更了。隨著柱塞轉(zhuǎn)動(dòng)的角度不同，柱塞的有效行程也就不同，因而供油量也隨之改變。

柱塞對(duì)于不供油位1轉(zhuǎn)動(dòng)的角度越大，則柱塞上端面到打開拄塞套回油孔的斜邊距離也越大，供油量也就越大，若柱塞轉(zhuǎn)動(dòng)的角度較小，則斷油開始較早，供油量也較小。當(dāng)柴油機(jī)停車時(shí)必須斷油，為此，可將柱塞上的縱向槽轉(zhuǎn)到正對(duì)著柱塞套上回油孔。此時(shí)，在整個(gè)柱塞行程中，柱塞套內(nèi)的燃油一直通過(guò)縱向槽、回油孔流回油道，沒(méi)有壓油過(guò)程，故供油量等于零。

機(jī)械原理

吸油壓油噴油泵的吸油和壓油，由柱塞在柱塞套內(nèi)的往復(fù)運(yùn)動(dòng)來(lái)完成。當(dāng)柱塞位于下部位置時(shí)，柱塞套上的兩個(gè)油孔被打開，柱塞套內(nèi)腔與泵體內(nèi)的油道相通，燃油迅速注滿油室。當(dāng)凸輪頂?shù)綕L輪體的滾輪上時(shí)，柱塞便升起。從柱塞開始間向上運(yùn)動(dòng)到油孔被柱塞上端面擋住前為止。在這一段時(shí)間內(nèi)，由于柱塞的運(yùn)動(dòng)，燃油從油室被擠出，流向油道。所以這段升程稱為預(yù)行程。當(dāng)柱塞將油孔擋住時(shí)，便開始?jí)河瓦^(guò)程。柱塞上行，油室內(nèi)油壓急劇升高。當(dāng)壓力超過(guò)出油閥的彈簧彈力和上部油壓時(shí)，就頂開出油閥，燃油壓入油管送至噴油器。

柱塞套上的進(jìn)油孔被柱塞上端面完全擋住的時(shí)刻稱為理論供油始點(diǎn)。柱塞繼續(xù)向上運(yùn)動(dòng)時(shí)，供油也一直繼續(xù)著，壓油過(guò)程持續(xù)到柱塞上的螺旋斜邊讓開柱塞套回油孔時(shí)為止，當(dāng)油孔一被打開，高壓油從油室經(jīng)柱塞上的縱向槽和柱塞套上的回油孔流回泵體內(nèi)的油道。此時(shí)柱塞套油室的油壓迅速降低，出油閥在彈簧和高壓油管中油壓的作用下落回閥座，噴油器立即停止噴油。這時(shí)雖然柱塞仍繼續(xù)上行，但供油已終止。 柱塞套上回油孔被柱塞斜邊打開的時(shí)刻稱為理論供油終點(diǎn)。在柱塞向上運(yùn)動(dòng)的整個(gè)過(guò)程中，只是中間一段行程才是壓油過(guò)程，這一行程稱為柱塞的有效行程。

高壓油泵首要用途是作為千斤頂、鐓頭器、擠壓機(jī)、扎花機(jī)等液壓設(shè)備的動(dòng)力源。高壓油泵的設(shè)備次第如下：在設(shè)備高壓油泵的過(guò)程中，為避免雜物落入機(jī)器內(nèi)，機(jī)組的全部孔穴均應(yīng)蓋好。將機(jī)組放在埋有地腳螺栓的基礎(chǔ)上，在底座與基礎(chǔ)之間，用成對(duì)的楔墊用校正用。校正泵軸和電機(jī)軸的同心度，在聯(lián)軸大道外圓上，容許差錯(cuò)0.1毫米;兩聯(lián)軸器平面的空地應(yīng)保證2～4毫米，(小泵取小值)空地要均勻，允差0.3毫米。
