結(jié)構(gòu)形式

      柱塞泵分為軸向柱塞泵和徑向柱塞泵兩種代表性的結(jié)構(gòu)形式,；柱塞缸由于徑向柱塞泵屬于一種新型的技術(shù)含量比較高的高效泵，隨著國產(chǎn)化的不斷加快,，徑向柱塞泵必然會成為柱塞泵應(yīng)用領(lǐng)域的重要組成部分。

      軸向柱塞泵是利用與傳動軸平行的柱塞在柱塞孔內(nèi)往復(fù)運動所產(chǎn)生的容積變化來進行工作的,。由于柱塞和柱塞孔都是圓形零件，加工時可以達到很高的精度配合,，因此具有容積效率高，運轉(zhuǎn)平穩(wěn),，流量均勻性好,，噪聲低,，工作壓力高等優(yōu)點，但對液壓油的污染較敏感,，結(jié)構(gòu)較復(fù)雜，造價較高,。

      柱塞泵的泵油機構(gòu)包括兩套精密偶件：柱塞+柱塞套構(gòu)成柱塞偶件、出油閥和出油閥座構(gòu)成出油閥偶件

      柱塞和柱塞套是一對精密偶件,，經(jīng)配對研磨后不能互換,，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、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精密偶件,，配對研磨后不能互換，其配合間隙為0.01mm ,。

      出油閥是一個單向閥，在彈簧壓力作用下,，閥上部圓錐面與閥座嚴密配合，其作用是在停供時,，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斷面，既能導(dǎo)向,，又能通過柴油。出油閥的錐面下有一個小的圓柱面,，稱為減壓環(huán)帶,，其作用是在供油終了時,，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)時則使上方容積很快增大，壓力迅速減小,，停噴迅速。
