1、Hydraulic SystemA complete hydraulic system consists of five parts, namely, power components, the implementation of components, control components, no parts and hydraulic oil. The role of dynamic components of the original motive fluid into mechanical energy to the pressure that the hydraulic system of pumps, it is to power the entire hydraulic system. The structure of the form of hydraulic pump gears are generally pump, vane pump and piston pump. Implementation of components (such as hydraulic。

2、Water-based hydraulic systemsWater-based hydraulic systems traditionally have been used in hot-metal areas of steel mills. The obvious advantage of water systems in these industries is their fire resistance. Water-based hydraulic systems also have obvious cost advantages over oil-based fluid. First, non-toxic, biodegradable synthetic additives for water cost $5 to $6 per gallon. One gallon of concentrate can make 20 gallons of a 5% solution, so the cost of water-based hydraul。

3、附 錄 2Hydraulic Brake SystemsWhen you step on the brake pedal,you expect the vehicle to stop.The brake pedal operates a hydraulic that is used for two reasons.First,fluid under pressure can be carried to all parts of the vehicle by small hoses or metal lines without taking up a lot of room of causing routing problems.Second,the hydraulic fluid offers a great mechanical advantage-little foot pressure is required on the pedal,but a great deal of pressure is generated at the wheels.The brake ped。

9、英文原文Self-advancing hydraulic powered supportModern longwall mining employs hydraulic powered supports at the face area. The supports not only holds up the roof, pushes the face chain conveyor, and advances itself, but also provides a safe environment for all associated mining activities. Therefore its successful selection and application are the prerequisite for successful longwall mining. Furthermore, due to the large number of units required, the capital invested for the power support usua。

11、附件 1：外文資料翻譯譯文 1 液壓傳動(dòng)概述 液壓傳動(dòng)的發(fā)展概況 壓傳動(dòng)的定義 一部完整的機(jī)器是由原動(dòng)機(jī)部分、傳動(dòng)機(jī)構(gòu)、控制部分及工作機(jī)部分組成。原動(dòng)機(jī)有幾種類型，例如電動(dòng)機(jī)、內(nèi)燃機(jī)等。工作機(jī)即完成該機(jī)器的工作任務(wù)的直接工作部分，如剪床的剪刀，車床的刀架、車刀、卡盤等。由于原動(dòng)機(jī)的功率和轉(zhuǎn)速比是被限制的，為了覆蓋工作機(jī)較大范圍的工作力和工作速度的變化，以及操作性能的要求，在原動(dòng)機(jī)和工作機(jī)之間設(shè)置了傳動(dòng)機(jī)構(gòu)，其作用是把原動(dòng)機(jī)輸出功率經(jīng)過變換后傳遞給工作機(jī)。 傳動(dòng)機(jī)構(gòu)通常分為電氣傳動(dòng)、 機(jī)械傳動(dòng)和流體傳動(dòng)三類。
