1× HPV 210-02 TC (回轉(zhuǎn)泵)
2× HMF 135-02  (回轉(zhuǎn)馬達(dá))

2× VT4 (方向控制閥)

日常作業(yè)中頻繁使用回轉(zhuǎn)功能的設(shè)備,比如本 例所示的抓料機(jī),從采用閉式系統(tǒng)的回轉(zhuǎn)中獲益。 這意味著整機(jī)其余的系統(tǒng)可以為工作性能進(jìn)行優(yōu)化 設(shè)計而不受回轉(zhuǎn)性能制約。本例中回轉(zhuǎn)系統(tǒng)由兩臺 定量馬達(dá)及一臺配置扭矩控制的變量泵組成,這種 控制方式集成比例流量控制及扭矩控制功能。在加速階段,流量控制使泵的排量迅速增加,回轉(zhuǎn)扭矩根據(jù)手柄動作成比例上升。扭矩控制決定 回轉(zhuǎn)動作的性能,即使再次加速時,動作仍然平穩(wěn) 有力
回轉(zhuǎn)泵的控制方式使操控與負(fù)載無關(guān),上車在手 柄回中位時的制動性能也可以定制,泵的位置反饋控 制可以補(bǔ)償負(fù)載影響。手柄回中位的上車回轉(zhuǎn)制動特 性通過機(jī)械方式預(yù)設(shè),不受動臂位移和抓斗負(fù)載影響?;匕馐直梢詼p小回轉(zhuǎn)制動角度,體現(xiàn)了林德驅(qū)動系 統(tǒng)的精髓:精準(zhǔn)、靈敏、可靠的隨心所欲的整機(jī)控制。 此系統(tǒng)為開式雙回路系統(tǒng),因此舉升力不受回轉(zhuǎn)運動 制約。串聯(lián)自調(diào)節(jié)泵與兩個閥組可以有效滿足不同操 色,能量損失小,降低了操作者的勞動強(qiáng)度。
