Hydraulic system for the lifts, excavators, pumping station, dynamic, crane, and so on largescale industry, construction, factories, enterprises, as well as elevators, lifting platforms, Deng Axle industry and so on. 另： 對于液壓系統(tǒng)這三大頑疾，有人進行了總結(jié)：“發(fā)燒、拉稀帶得瑟”（這位總結(jié)者是東北人）。整個液壓系統(tǒng)應(yīng)有良好的減振措施，同時還要避免外來振源對系統(tǒng)的影響。同時由于較高的溫度，液壓油會發(fā)生膨脹，導(dǎo)致壓縮性增大，使控制動作無法很好的傳遞。內(nèi)漏會引起液壓系統(tǒng)容積效率急劇下降，達不到所需要的工作壓力，甚至不能進行工作。 2, vulnerable performance as a result of the impact of temperature change, it would be inappropriate in the high or low temperature conditions. 由于工作性能易受到溫度變化的影響，因此不宜在很高或很低的溫度條件下工作。 2, light weight, small size, small inertia, fast response. 重量輕、體積小、運動慣性小、反應(yīng)速度快。 Working principle of the system, you can turn on all circuits to code. If the first implementation of ponents numbered 0, the control ponents associated with the identifier is 1. Out with the implementation of ponents corresponding to the identifier for 4 the even ponents, then retracting and implementation of ponents corresponding to the identifier for the odd ponents. Hydraulic circuit carried out not only to deal with numbers, but also to deal with the actual device ID, in order to detect system failures. 根據(jù)系統(tǒng)工作原理，您可對所有回路依次進行編號。 Part of the hydraulic power means that the circuit diagram used to show the different functions of the interrelationship between ponents. Containing the source of hydraulic pump, hydraulic motor and auxiliary ponents。根據(jù)控制功能的不同，液壓閥可分為壓力控制閥、流量控制閥和方向控制閥。 militaryindustrial control devices used in artillery, ship anti rolling devices, aircraft simulation, aircraft retractable landing gear and rudder control devices and other devi ces. 液壓傳動有許多突出的優(yōu)點，因此它的應(yīng)用非常廣泛，如一般工業(yè)用的塑料加工機械、壓力機械、機床等；行走機械中的工程機械、建筑機械、農(nóng)業(yè)機械、汽車等；鋼鐵工業(yè)用的冶金機械、提升裝置、軋輥調(diào)整裝置等；土木水利工程用的防洪閘門及堤壩裝置、河床升降裝置、橋梁操縱機構(gòu)等；發(fā)電廠渦輪機調(diào)速裝置、核發(fā)電廠等等；船舶用的甲板起重機械（絞車）、船頭門、艙壁閥、船尾推進器等；特殊技術(shù)用的巨型天線控制裝置、測量浮標(biāo)、升降旋轉(zhuǎn)舞臺等；軍事工業(yè)用的火炮操縱裝置、船舶減搖裝置、飛行器仿真、飛機起落架的收放裝置和方向舵控制裝置等。近 20~30 年間，日本液壓傳動發(fā)展之快，居世界領(lǐng)先地位。 1925 年維克斯 ()發(fā)明了壓力平衡式葉片泵 ,為近代液壓元件工業(yè)或液壓傳動的逐步建立奠定了基礎(chǔ)。 1 Hydraulic System 液壓系統(tǒng) Hydraulic presser drive and air pressure drive hydraulic fluid as the transmission is made according to the 17th century, Pascal39。 20 世紀(jì)初康斯坦丁?尼斯克 (G?Constantimsco)對能量波動傳遞所進行的理論及實際研究 。 Hydraulic transmission There are many outstanding advantages, it is widely used, such as general industr ial use of plastics processing machinery, the pressure of machinery, machine 2 tools, etc.。 A plete hydraulic system consists of five parts, namely, power ponents, the implementation of co mponents, control ponents, auxiliary ponents and hydraulic oil. 一個完整的液壓系統(tǒng)由五個部分組成，即動力元件、執(zhí)行元件、控制元件、輔助元件和液壓油。壓力控制閥又分為益流閥 (安全閥 )、減壓 3 閥、順序閥、壓力繼電器等；流量控制閥包括 節(jié)流閥、調(diào)整閥、分流集流閥等；方向控制閥包括單向閥、液控單向閥、梭閥、換向閥等。 hydraulic control part contains a variety of control valves, used to control the flow of oil, pressure and direction。如果第一個執(zhí)行元件編號為 0，則與其相關(guān)的控制元件標(biāo)識符則為 1。 3, to facilitate manipulation of control, enabling a wide range of stepless speed regulation (speed range of 2021:1). 操縱控制方便，可實現(xiàn)大范圍的無級調(diào)速（調(diào)速范圍達 2021： 1）。 3, the manufacture of precision hydraulic ponents require a higher, more expensive and hence the price. 液壓元件的制造精度要求較高，因而價格較貴。侵入系統(tǒng)中的微小灰塵顆粒，會引起或加劇液壓元件摩擦副的磨損，進一步導(dǎo)致泄漏。解決辦法：發(fā)熱是液壓系統(tǒng)的固有特征，無法根除只能盡量減輕。 3, the leakage of the hydraulic system leak into inside and outside the leakage leakage.
