工作時，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、下往復運動，從而完成泵油任務，泵油過程可分為以下三個階段。結論：通過上述討論，得出下列結論① 柱塞往復運動總行程L是不變的，由凸輪的升程決定。② 柱塞每循環(huán)的供油量大小取決于供油行程，供油行程不受凸輪軸控制是可變的。③ 供油開始時刻不隨供油行程的變化而變化。④ 轉動柱塞可改變供油終了時刻，從而改變供油量。3. 國產(chǎn)系列柱塞式噴油泵國產(chǎn)系列柱塞泵主要有A、B、P、Z和Ⅰ、Ⅱ、Ⅲ號等系列。系列化是根據(jù)柴油機單缸功率范圍對供油量的要求不同，以柱塞行程，泵缸中心距和結構型式為基礎，再分別配以不同尺寸的柱塞直徑，組成若干種在一個工作循環(huán)內供油量不等的噴油泵，以滿足各種柴油機的需要。國產(chǎn)系列噴油泵的工作原理和結構型式基本相同，以A型泵為例介紹柱塞式噴油泵的構造和工作原理。柱塞泵由四大部分組成：分泵、油量調節(jié)機構、傳動機構和泵體為微處理器智能控制，液晶屏顯示，可與電腦進行通訊，具有工作壓力穩(wěn)定、脈動小、操作方便等特點。廣泛用于生化、醫(yī)藥、化工、環(huán)保等行業(yè)，滿足以上行業(yè)需要連續(xù)恒壓、恒流輸送液體的要求。 [1]
