 威格士Vickers柱塞泵廠家現(xiàn)貨直銷(xiāo)，我公司長(zhǎng)期經(jīng)銷(xiāo)威格士柱塞泵，不僅價(jià)格好，質(zhì)量?jī)?yōu)。而且功能也很好，貨期還短。您還在猶豫什么，趕快來(lái)咨詢(xún)采購(gòu)吧。美國(guó)VICKERS威格士柱塞泵是依靠柱塞與缸體內(nèi)孔面來(lái)形成密封工作容積的。由于柱塞與缸體內(nèi)孔均為圓柱表面，因此加工方便，配合精度高，密封性能好。故柱塞泵常做成高壓泵。優(yōu)點(diǎn)：壓力高、結(jié)構(gòu)緊湊、效率高及流量調(diào)節(jié)方便。缺點(diǎn)：結(jié)構(gòu)復(fù)雜，價(jià)格較貴。

Vickers威格士柱塞泵按柱塞排列方向的不同，分為軸向柱塞泵和徑向柱塞泵。在此，簡(jiǎn)要介紹軸向柱塞泵和回轉(zhuǎn)式徑向柱塞泵。Vickers威格士軸向柱塞泵。軸向柱塞泵由配流盤(pán)、缸體（轉(zhuǎn)子）、柱塞和斜盤(pán)等主要零件組成。在配流盤(pán)上開(kāi)有兩個(gè)弧形溝槽，分別與泵的吸、壓油口連通，形成吸油腔和壓油腔。斜盤(pán)、配流盤(pán)均與泵體相固定，柱塞在彈簧的作用下以球形端頭與斜盤(pán)接觸。兩個(gè)弧形溝槽彼此隔開(kāi)，保持一定的密封性。斜盤(pán)相對(duì)于缸體的夾角為γ。原動(dòng)機(jī)通過(guò)傳動(dòng)軸帶動(dòng)缸體旋轉(zhuǎn)，柱塞就在柱塞孔內(nèi)作軸向往復(fù)滑動(dòng)。處于π～2π范圍內(nèi)的柱塞向外伸出，使其底部的密封容積增大，將油吸入；處于0～π范圍內(nèi)的柱塞向缸體內(nèi)壓入，使其底部的密封容積減小，把油壓往系統(tǒng)中。

顯然，泵的輸油量決定于柱塞往復(fù)運(yùn)動(dòng)的行程長(zhǎng)度，也就是決定于斜盤(pán)的傾角γ。如果γ角可以調(diào)整，就成為變量泵。γ角越大，輸油量也就越大。

Vickers威格士徑向柱塞泵。所示當(dāng)轉(zhuǎn)子旋轉(zhuǎn)時(shí)，柱塞在離心力作用下，它的頭部與定子內(nèi)表面緊緊接觸，由于轉(zhuǎn)子與定子之間有一個(gè)偏心量е，所以柱塞在隨轉(zhuǎn)子轉(zhuǎn)動(dòng)的同時(shí)，又在柱塞孔內(nèi)作徑向往復(fù)滑動(dòng)。當(dāng)轉(zhuǎn)子按圖中箭頭所示方向旋轉(zhuǎn)時(shí)，上半周的柱塞皆往外滑動(dòng)，柱塞孔內(nèi)的密封容積增大，于是通過(guò)軸向孔吸油；下半周的柱塞皆往里滑動(dòng)，柱塞孔內(nèi)的密封容積減少，于是通過(guò)軸向孔壓油。

vickers威格士柱塞泵的泵油機(jī)構(gòu)包括兩套精密偶件：柱塞（plunger）+柱塞套(barrel)構(gòu)成柱塞偶件(plunger and barrel assembly)、出油閥（delivery valve）和出油閥座(delivery valve seat)構(gòu)成出油閥偶件(delivery valve assembly 柱塞和柱塞套是一對(duì)精密偶件，經(jīng)配對(duì)研磨后不能互換，要求有高的精度和光潔度和好的耐磨性，其徑向間隙為0.002～0.003mm 柱塞頭部圓柱面上切有斜槽，并通過(guò)徑向孔、軸向孔與頂部相通，其目的是改變循環(huán)供油量；柱塞套上制有進(jìn)、回油孔，均與泵上體內(nèi)低壓油腔相通，柱塞套裝入泵上體后，應(yīng)用定位螺釘定位。 柱塞頭部斜槽的位置不同，改變供油量的方法也不同。 出油閥和出油閥座也是一對(duì)精密偶件，配對(duì)研磨后不能互換，其配合間隙為0.01mm 。 出油閥是一個(gè)單向閥，在彈簧壓力作用下，閥上部圓錐面與閥座嚴(yán)密配合，其作用是在停供時(shí)，將高壓油管與柱塞上端空腔隔絕，防止高壓油管內(nèi)的油倒流入噴油泵內(nèi)。 出油閥的下部呈十字?jǐn)嗝妫饶軐?dǎo)向，又能通過(guò)柴油。出油閥的錐面下有一個(gè)小的圓柱面，稱(chēng)為減壓環(huán)帶，其作用是在供油終了時(shí)，使高壓油管內(nèi)的油壓迅速下降，避免噴孔處產(chǎn)生滴油現(xiàn)象。當(dāng)環(huán)帶落入閥座內(nèi)時(shí)則使上方容積很快增大，壓力迅速減小，停噴迅速。 工作時(shí)，在噴油泵凸輪軸上的凸輪與柱塞彈簧的作用下，迫使柱塞作上、下往復(fù)運(yùn)動(dòng)，從而完成泵油任務(wù)，泵油過(guò)程可分為以下三個(gè)階段。
