Adjustment-最大排量限制器

Maximumdisplacementlimiter通過(guò)限制伺服控制活塞行程，調(diào)節(jié)馬達(dá)最大排量。采用一個(gè)限位螺栓及一個(gè)套筒，限定馬達(dá)最大排量。排量限定降低值以最大排量5％為單位。改變最大排量限定值時(shí)，需要更換不同長(zhǎng)度的螺栓并配合特定長(zhǎng)度的套筒。提供一穩(wěn)定流量，觀察處于最大排量下馬達(dá)輸出轉(zhuǎn)速。確認(rèn)馬達(dá)最大排量設(shè)定是否改變。增加最大排量設(shè)定將降低馬達(dá)輸出轉(zhuǎn)速，降低最大排量設(shè)定將增加馬達(dá)輸出轉(zhuǎn)速。51系列馬達(dá)1.用下面工具拆下伺服端蓋(G260)4個(gè)安裝螺栓(G24)：?8mm內(nèi)六角螺栓(060cm3,080cm3,110cm3,及160cm3馬達(dá)),或:?10mm內(nèi)六角螺栓(250cm3馬達(dá))。2.拆下伺服端蓋(G260)，O型圈(G36)及(G100)。3.用10mm內(nèi)六角扳手，拆下排量限制器螺栓(F10)及套筒(F20)(如馬達(dá)已帶最大排量限制)。4.針對(duì)特定最大排量限定要求，更換合適長(zhǎng)度的螺栓及套筒（具體見(jiàn)下頁(yè)表格）。51系列馬達(dá)最大排量限制器Series51MaximumdisplacementlimiterAdjustment-最大排量限制器
