HED8OP-2X/100K14S力士樂HDE8系列壓力開關訂貨資料
力士樂液壓傳動技術已經廣泛應用于很多工程技術領域,由于液壓系統所服務的主機的工作循環、動作特點等各不相同,相應的各液壓系統的組成、作用和特點也不盡相同。以下通過對幾個典型液壓系統的分析,進一步熟悉各液壓元件在系統中的作用和各種基本回路的組成,并掌握分析液壓系統的方法和步驟。HED8OP-2X/100K14S力士樂HDE8系列壓力開關訂貨資料
閱讀一個較為復雜的液壓系統圖,大致可按以下步驟進行:
(1)了解設備的工藝對液壓系統的動作要求;
(2)初步游覽整個系統, 了解系統中包含有哪些元件,并以各個執行元件為中心,將系統分解為若干子系統。
(3)對每一子系統進行分析,搞清楚其中含有哪些基本回路,然后根據執行元件的動作要求,參照動作循環表讀懂這一子系統。
(4)根據液壓設備中各執行元件間互鎖、同步、防干涉等要求,分析各子系統之間的聯系。
(5)在全面讀懂系統的基礎上,歸納總結整個系統有哪些特點,以加深對系統的理解。
一,組合機床液壓系統
組合機床液壓系統主要由通用滑臺和輔助部分(如定位、夾緊)組成。動力滑臺本身不帶傳動裝置,可根據加工需要安裝不同用途的主軸箱,以完成鉆、擴、鉸、鏜、刮端面、銑削及攻絲等工序。
有液壓夾緊的他驅式動力滑臺的液壓系統原理圖,這個系統采用限壓式變量泵供油,并配有二位二通電磁閥卸荷,變量泵與進油路的調速閥組成容積節流調速回路,用電液換向閥控制液壓系統的主油路換向,用行程閥實現快和工進的速度換接。
二,液壓系統的特點
液壓系統采用限壓式變量泵和調速閥組成容積節流調速系統,把調速閥裝在進油路上,而在回油路上加背壓閥。這樣就獲得了較好的低速穩定性、較大的調速范圍和較高的效率。而且當滑臺需死擋鐵停留時,用壓力繼電器發出信號實現快退比較方便。
采用限壓式變量泵并在快進時采用差動連接, 不僅使快進速度和快退速度相同差動缸),而且比不采用差動連接的流量可誠小一倍,其能量得到合理利用,系統效率進一步得到提高。
采用電液換向閥使換向時間可調,改善和提高了換向性能。采用行程閥和液控順序閥來實現快進與工進的轉換,比采用電磁閥的電路簡化,而且使速度轉換動作可靠,轉換精度也較高。此外,用兩個調速閥串聯來實現兩次工進, 使轉換速度平穩而無沖擊。
夾緊油路中串接誠壓閥,不僅可使其壓力低于主油路壓力,而且可根據工件夾緊力的需要來調節并穩定其壓力;當主系統快速運動時,即使主油路壓力低于減壓閥所調壓力,因為有單向閥的存在,夾緊系統也能維持其壓力(保壓)。夾緊油路中采用二位四通閥,它的常態位置是夾緊工件,這樣即使在加工過程中臨時停電,也不至于使工件松開,保證了操作安全可靠。

功能、組成部分、符號
HED 8 類型的液壓-電氣壓力開關是柱塞式壓力開關。它們的基
本構成是殼體 (1)、帶柱塞的安裝套件 (2)、壓縮彈簧 (3)、調節
元件 (4) 和微動開關 (5)。
如果要監測的壓力低于調定值,則操作微動開關 (5)。要監測的
壓力通過節流孔 (7) 傳到柱塞 (2)。柱塞 (2) 受彈簧座 (6) 支持并
克服壓縮彈簧 (3) 不斷變化的作用力。彈簧座 (6) 將柱塞 (2) 的運
動傳輸到微動開關 (5),并在達到調定壓力時釋放后者的壓力。
這將打開或關閉電路,取決于電路的設置。彈簧座 (6) 的機械前
擋塊在壓力突然降低和過壓的情況下,可保護微動開關 (5) 免于
受到機械損傷,并防止壓縮彈簧 (3) 的過壓。
注意事項:
要延長使用壽命,安裝壓力開關時應確保振動較小,使其免
于受到液壓沖擊。
