給大家(jia)講講關于山(shan)東小(xiao)型(xing)裝(zhuang)載(zai)(zai)機(ji)的(de)轉向系統方面的(de)特點，山(shan)東小(xiao)型(xing)裝(zhuang)載(zai)(zai)機(ji)是從大型(xing)裝(zhuang)載(zai)(zai)機(ji)執行系統功能分(fen)析(xi)著手(shou)，對裝(zhuang)載(zai)(zai)機(ji)進行了創新設計，廣泛用于公路、鐵路、水電、建筑、港口(kou)、礦山(shan)等建設工程的(de)土(tu)石方施工機(ji)械。

目前小型裝(zhuang)載機液(ye)(ye)壓(ya)轉向(xiang)(xiang)(xiang)系(xi)(xi)(xi)統(tong)(tong)(tong)采用開式(shi)定量(liang)泵系(xi)(xi)(xi)統(tong)(tong)(tong)，其特(te)點是結構簡(jian)單、散熱充分。轉向(xiang)(xiang)(xiang)液(ye)(ye)壓(ya)系(xi)(xi)(xi)統(tong)(tong)(tong)又(you)有(you)合(he)流(liu)系(xi)(xi)(xi)統(tong)(tong)(tong)與不(bu)合(he)流(liu)系(xi)(xi)(xi)統(tong)(tong)(tong)之分。合(he)流(liu)系(xi)(xi)(xi)統(tong)(tong)(tong)是指將轉向(xiang)(xiang)(xiang)液(ye)(ye)壓(ya)系(xi)(xi)(xi)統(tong)(tong)(tong)的油引到工(gong)作裝(zhuang)置液(ye)(ye)壓(ya)系(xi)(xi)(xi)統(tong)(tong)(tong)，不(bu)合(he)流(liu)系(xi)(xi)(xi)統(tong)(tong)(tong)是指轉向(xiang)(xiang)(xiang)泵的油專門供轉向(xiang)(xiang)(xiang)液(ye)(ye)壓(ya)系(xi)(xi)(xi)統(tong)(tong)(tong)。

流量(liang)放大轉(zhuan)向(xiang)。轉(zhuan)向(xiang)泵流量(liang)優先供(gong)給(gei)轉(zhuan)向(xiang)系(xi)統，多余流量(liang)合流到工作系(xi)統。

優先負荷傳感(gan)轉向(xiang)(xiang)。轉向(xiang)(xiang)泵(beng)流(liu)(liu)量優先保證(zheng)通過轉向(xiang)(xiang)器進(jin)入轉向(xiang)(xiang)油(you)缸，且流(liu)(liu)量不受轉向(xiang)(xiang)壓(ya)力變化影響，多(duo)余(yu)流(liu)(liu)量進(jin)入工(gong)作或其他系統。

同(tong)軸流量(liang)放大(da)轉(zhuan)(zhuan)向(xiang)。與(yu)優先負荷傳感轉(zhuan)(zhuan)向(xiang)基本相同(tong)，區別僅(jin)為轉(zhuan)(zhuan)向(xiang)器不同(tong)，進入轉(zhuan)(zhuan)向(xiang)器的流量(liang)一(yi)小部分(fen)(fen)通過(guo)轉(zhuan)(zhuan)向(xiang)器計量(liang)馬(ma)達，大(da)部分(fen)(fen)（按比例）通過(guo)轉(zhuan)(zhuan)向(xiang)器內部油道與(yu)小部分(fen)(fen)匯合(he)再進入轉(zhuan)(zhuan)向(xiang)缸。
