(dòng)行駛系統(tǒng)、液壓馬達(dá)和相應(yīng)的液壓回路構(gòu)成了液壓行走子系統(tǒng)，為系統(tǒng)的補(bǔ)油泵，與定量泵同軸連接。該系統(tǒng)由集成控制閥塊實(shí)現(xiàn)對(duì)油路和液壓泵的控制。變量泵及馬達(dá)的選型，基本根據(jù)前述的功率值來(lái)確定。液壓馬達(dá)驅(qū)動(dòng)噴水系統(tǒng)由定量泵、定量液壓馬達(dá)、水泵、溢流閥、冷卻器、過(guò)濾器和液壓缸及疊加閥組等組成。為液壓缸和疊加閥組共同組成，用于控制噴水架的升降、伸縮等動(dòng)作。液壓油返回油箱時(shí)，經(jīng)過(guò)水冷卻器冷卻。4水噴射系統(tǒng)水系統(tǒng)是高壓清洗車(chē)的核心部分主要由高壓水泵、噴水架、噴嘴、噴槍及閥等組成。水箱流出的水經(jīng)水泵后將水壓提高到8MP,形成高壓射流噴射到路面。高壓泵的合理選取，對(duì)發(fā)動(dòng)機(jī)效率的最佳利用、最佳沖洗效率都有重要的影響，需要根據(jù)設(shè)計(jì)要求及發(fā)動(dòng)機(jī)參數(shù)等來(lái)確定高壓泵的功率、工作轉(zhuǎn)速和泵壓等參數(shù)。水系統(tǒng)設(shè)計(jì)中的主要問(wèn)題包括以下兩個(gè)方面。4
