典型液壓系統分析步驟
液壓系統設計是根據液壓設備的工作要求,選用適當的基本回路構成的,其原理一般用液壓系統圖來表示。液壓系統圖反映了液
壓系統所采用的液壓元件的類型、電念頭規格、液壓系統的動作順序、控制方式等內容。分析一個較復雜的液壓系統,大致可以
按以下步驟進行:
(1)了解設備對液壓系統的要求。
(2)根據設備對系統的要求,以執行元件為中央將整個系統分解為若干子系統。
(3)根據對執行元件的動作要求。參照電磁鐵動作順序表,逐步分析各子系統的換向回路、調速回路、壓力控制回路等。
(4)根據設備各執行元件間的互鎖、同步、順序動作和互不干擾等要求,分析各子系統之間的聯系。
(5)歸納總結整個系統的特點,以加深對系統的理解。
液壓傳動在機械制造、工程機械、運輸、船舶、航空、航天等領域有著廣泛的應用,因各種設備的工作要求不同,其液壓系統的組成、工作原理和特點也不盡相同。本章將通過對幾個典型液壓系統的先容,認識各種液壓元件在液壓系統中的作用和各種基本回路的構成,進而把握分析液壓系統的方法和步驟,以便為準確使用液壓系統,改造設備和技術革新提供必備的基礎知識。

Installed into the hydraulic system pump What are the requirements
Hydraulic pump and electric motor bearing or flange should be used together with a device foundation. Foundation, flange or bearing stiffness are necessary to have contented to avoid oscillation occurs when the hydraulic pump and noise . Hydraulic pump unit
There are the following requirements:
1 , in accordance with the use of a single hydraulic diagram imitation devices.
2, the pump shaft and the electric motor (drive 電子商務anization ) shaft rotation direction of the pump needs necessary direction . c shaft and the electric motor ( Transmission 電子商務anization ) coaxial shafts should be less than 0.1mm , the tilt angle can not
Greater than 1 °. Coupling device , do not hit, to avoid damage to the hydraulic pump rotors and other parts. Device must be accurate, reliable .
3 , fastening hydraulic pumps, electric motor or drive 電子商務anizations to corner screws , bolts should be evenly and force knot securely .
4, hand shift couplings should feel 免費信息fortable changing the hydraulic pump , no obstruction or abnormal appearance, and talent enough piping . 6.2.2 Requirements hydraulic cylinder device
5 , the hydraulic cylinder is necessary to seriously follow the instruction sheet in accordance with the use of a hydraulic diagram devices and knot securely , without any loose.
6 , the hydraulic cylinder piston rod with the femoral artery and the tissue interface , and from the action several times , and to ensure that 電子商務anizations and mobile hydraulic cylinder intermediate rail surface parallelism within 0.1mm . c hydraulic cylinder piston rod
Femoral artery to reach the table moves agility simple, in any department of the whole trip was no catching appearance . After adjusting screws tightened and should knot securely . d device before serious view of hydraulic
Cylinder own installation quality , recognizing outstanding quality hydraulic cylinders mounted after talent Ann Ge on the device.
