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),泵油過程可分為以下三個(gè)階段。結(jié)論:通過上述討論,得出下列結(jié)論① 柱塞往復(fù)運(yùn)動(dòng)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(shí)刻不隨供油行程的變化而變化。④ 轉(zhuǎn)動(dòng)柱塞可改變供油終了時(shí)刻,從而改變供油量。3. 國(guó)產(chǎn)系列柱塞式噴油泵國(guó)產(chǎn)系列柱塞泵主要有A、B、P、Z和Ⅰ、Ⅱ、Ⅲ號(hào)等系列。系列化是根據(jù)柴油機(jī)單缸功率范圍對(duì)供油量的要求不同,以柱塞行程,泵缸中心距和結(jié)構(gòu)型式為基礎(chǔ),再分別配以不同尺寸的柱塞直徑,組成若干種在一個(gè)工作循環(huán)內(nèi)供油量不等的噴油泵,以滿足各種柴油機(jī)的需要。國(guó)產(chǎn)系列噴油泵的工作原理和結(jié)構(gòu)型式基本相同,以A型泵為例介紹柱塞式噴油泵的構(gòu)造和工作原理。柱塞泵由四大部分組成:分泵、油量調(diào)節(jié)機(jī)構(gòu)、傳動(dòng)機(jī)構(gòu)和泵體為微處理器智能控制,液晶屏顯示,可與電腦進(jìn)行通訊,具有工作壓力穩(wěn)定、脈動(dòng)小、操作方便等特點(diǎn)。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。A2F45R6.1B3 A2F45L6.1B3 A2F45W6.1B3
