博士力士樂清洗與溢流閥塊的工作油口 A 與 B 都可按用戶的要求,連接高壓或低壓油液。由高壓控制的清洗滑閥,可確保在進行高-低油壓端的切換時,使清洗閥可靠地與低壓油口相連。 由于博士力士樂SDVB型閥塊為雙向作用式溢流閥采用先導控制功能,因而只需很小的操縱力就能設置油路兩個高壓端所需要的壓力值。這些設定值的設置,可以相互獨立地進行。對于規(guī)格 30 和 50 閥塊,還可通過外部先導油口(X 和 Y)實現(xiàn)遠程控制功能。一旦啟動了溢流閥,高壓端的液壓油就可以流向低壓端。設定的壓力值,對應于高、低壓之間的壓降值。與這種閥的通流 能力相比,其結(jié)構(gòu)極為緊湊。 博士力士樂SDVB型清洗與溢流閥塊還可用作一種雙向作用式溢流閥。在用作溢流閥 時,清洗閥的供油管路應當處于封閉狀態(tài)。 采用單獨或直接安裝的卸載閥之后,既可以通過外部將先導閥與 油箱相連,也可以在內(nèi)部與低壓端相連。利用這一項功能,就可 以將 SDVB 30 和 50 用作旁通閥。對于采用SDVB 型沖洗與溢流 閥塊的高動態(tài)運行,在改變了高壓端之后油口A 和 B 之間仍會有 短時間的自由流動。這種應用適合使用直動式閥塊;為此,我們 可根據(jù)用戶要求提供 16和 30 兩種規(guī)格的產(chǎn)品。

或 B)直接測量工作壓力。 壓力設定范圍: 工作壓力: pv min…pv max = 50…400 bar SDVB 16、30 和 50 在公稱流量 qNSp 時的清洗壓力:均為 無限可調(diào)。訂購時,請注明要求的工作壓力和清洗壓力設置 值。更多詳情請參見 RC 92100。 油液的溫度范圍: ϑm min…ϑm max = –20° C…+80° C 粘度范圍: νmin…νmax = 10…1000 mm2 /s 切換壓力——為了在兩個方向上實現(xiàn)清洗閥回路 A 和 B的切換,就必須在高壓 和低壓端之間建立起一個壓差。 這一壓差、以及由此在高壓端形成的切換壓力,與低壓端的設定 值有關。而對于 SDVB 30 和 50,還必須考慮彈簧力的作用,因 為這種作用相當于還需再上升約 9 bar 的壓力,才能使閥口* 打開(參見左圖)。 先導油液的zui大流量 QSt

或者將清洗閥的壓力設為高于低壓端的相應值即可。 博士力士樂SDVB型清洗與溢流閥塊為A4VSG和A2P柱塞泵的控制元件。Rexroth清洗與溢流閥塊的作用是:保持輸送壓力并排出多余的油液,以限制閉式液壓回路中的工作壓力。 博士力士樂SDVB清洗與溢流閥塊還可用作一種雙向作用式溢流閥。在用作溢流閥時,清洗閥的供油管路應當處于封閉狀態(tài)。我公司在為您提供力士樂軸向柱塞泵的情況下,我們還為您提供該產(chǎn)品的控制元件——SDVB型清洗與溢流閥塊。 Rexroth清洗與溢流閥塊,力士樂SDVB型清洗與溢流閥塊,博士力士樂軸向柱塞變量泵控制閥塊 |
