?柱塞泵是工程機(jī)械設(shè)備中最常用的泵車(chē)產(chǎn)品之一具有體積小、重量輕、移動(dòng)方便、成本低等特點(diǎn)，但在目前國(guó)內(nèi)混凝土柱塞泵的應(yīng)用領(lǐng)域十分有限我國(guó)市場(chǎng)上最大的液壓柱塞泵占到了我國(guó)泵車(chē)市場(chǎng)的50%以上比重特別是近幾年來(lái)，隨著混凝土施工市場(chǎng)需求的不斷擴(kuò)大以及建筑施工技術(shù)的不斷進(jìn)步和發(fā)展，建筑行業(yè)施工設(shè)備需求的不斷擴(kuò)大。
隨著施工行業(yè)對(duì)工程施工效率、對(duì)環(huán)保要求越發(fā)嚴(yán)格而導(dǎo)致市場(chǎng)需求旺盛（尤其是對(duì)混凝土施工方面）工程施工市場(chǎng)出現(xiàn)了許多新設(shè)備，這些設(shè)備又要大量人力投入)柱塞泵的工作原理：首先泵車(chē)運(yùn)轉(zhuǎn)前必須將液壓油加注至規(guī)定溫度。
但液壓油是流動(dòng)性的，當(dāng)液壓油溫度高于40℃時(shí)就會(huì)變質(zhì)在發(fā)動(dòng)機(jī)運(yùn)行前需要更換液壓油液壓油在液壓系統(tǒng)中起著泵送液體和輸送液體目的作用柱塞泵在整個(gè)使用過(guò)程中要注意操作方法，只有正確操作才能保證它正常的工作 為了方便地實(shí)現(xiàn)自動(dòng)調(diào)節(jié)排量，通常都采用自動(dòng)調(diào)節(jié)缸行程和缸壓的方法。
而泵的手動(dòng)排量控制則采用了對(duì)缸行程和缸壓的自動(dòng)調(diào)節(jié)方法其目的是防止泵在運(yùn)行中發(fā)生沖擊和振動(dòng)，以降低設(shè)備摩擦磨損和發(fā)熱損壞零件柱塞泵操作時(shí)可以通過(guò)調(diào)節(jié)缸行程來(lái)調(diào)節(jié)缸內(nèi)容積，從而實(shí)現(xiàn)自動(dòng)調(diào)節(jié)輸出軸排量的目的。
具體操作是：先把每個(gè)缸的缸壓調(diào)到小的標(biāo)準(zhǔn)排量：即：每只小缸的標(biāo)準(zhǔn)排量=該缸排量×缸壓×排量；然后把所需的流量乘以缸壓使缸壓力由低到高，直至達(dá)到設(shè)計(jì)值為下限同時(shí)還需要注意觀(guān)察缸內(nèi)工作壓力是否與所設(shè)定的自動(dòng)調(diào)節(jié)流量一致。
這樣就能知道自動(dòng)調(diào)節(jié)缸閥的行程或缸壓有多大了在進(jìn)行自動(dòng)調(diào)節(jié)流量時(shí)一定要做到“少排量，多調(diào)節(jié)”才能達(dá)到自動(dòng)調(diào)節(jié)流量的目的另外，還有一種自動(dòng)調(diào)節(jié)缸壓的方法：即當(dāng)缸壓過(guò)大時(shí)應(yīng)適當(dāng)?shù)卦龃蟾讐?，以使壓差在小限度?nèi);但若缸壓過(guò)小,則自動(dòng)調(diào)節(jié)閥易損壞零部件而無(wú)法實(shí)現(xiàn)自動(dòng)調(diào)速。
