【正文】 gn analysis, manufacturing, marketing and following is a list of the major areas of consideration in the general field of machine design: ① Initial design conception。④ Corrosion。 Only displacement energy converters are dealt with in the elements performing converters provide one or several of the working chambers in a pump is produced by the external energy admitted, and in the motor by the hydraulic of the fluid occurs during expansion of the working chamber, while the outflow(displacement)is realized during devices are usually called displacement energy Hydrostatic PowerIn order to have a fluid of volume V1 flowing in a vessel at pressure work spent on pression W1 and transfer of the process, let us imagine a piston mechanism((a))which may be connected with the aid of valves Z0 and Z1 to the external medium under pressure P0 and reservoir of pressure the upper position of the piston(x=x0)with Z0 open the cylinder chamber is filled with fluid of volume V0 and pressure shut the value Z0 and start the piston moving Z1 is shut the fluid volume in position X=X1 of the piston decreases from V0 to V1, while the pressure rises to external work required for actuation of the piston(assuming isothermal change)is W1=∫0x0(PP0)Adx=∫v1v0(PP0)dvSelect from Hydraulic Power

①目測(cè) ②冶金測(cè)試 ③尺寸測(cè)試④損傷檢驗(yàn) ⑤性能檢驗(yàn) 目測(cè)目測(cè)檢驗(yàn)一種產(chǎn)品或原料的某些特征，如顏色、紋理、表面光潔度或部件的總體外觀，從而判斷其是否具有明顯的缺損。性能測(cè)試性能測(cè)試在零部件被其他產(chǎn)品被安裝之前，檢查部件的功能，尤其是那些機(jī)械構(gòu)造復(fù)雜的部件。（圖21）這種能量轉(zhuǎn)化的理論上的設(shè)計(jì)依據(jù)是液力傳動(dòng)的各部分的伯努里方程。主要設(shè)計(jì)特點(diǎn)聯(lián)鎖式退距均等裝置，專利技術(shù)，在使用過(guò)程中可始終保持兩側(cè)瓦塊制動(dòng)襯浮貼制動(dòng)輪的現(xiàn)象；設(shè)有瓦塊自動(dòng)隨位裝置。RKW系列制動(dòng)器為常開(kāi)式、液壓驅(qū)動(dòng)、臥式安裝的制動(dòng)器。地面情況當(dāng)起重機(jī)操作困難時(shí)，在平整的路面上（體育場(chǎng)，碼頭，倉(cāng)庫(kù)等）起構(gòu)造是傳統(tǒng)概念的單驅(qū)動(dòng)的運(yùn)輸工具。有時(shí)，對(duì)材料及零件的測(cè)試是很必要的，但由于無(wú)損測(cè)試的花費(fèi)和成本及時(shí)間不是任何時(shí)候都允許的。生產(chǎn)制造公司的原材料檢驗(yàn)員到供應(yīng)廠并且檢查原材料及于制造的另配件。例如，汽車的冷卻系統(tǒng)的散熱器皮帶管松開(kāi)。當(dāng)然，所有的計(jì)算依賴于這些結(jié)構(gòu)材料通過(guò)試驗(yàn)測(cè)定的物理性能。hydraulic

parts be made strong enough to prevent designer should determine as precisely as possible the nature, magnitude, direction and point of application of all design is mot, however, an exact science and it is, therefore, rarely possible to determine exactly all the applied addition, different samples of a specified material will exhibit somewhat different abilities to resist loads, temperatures and other environment spite of this, design calculations based on appropriate assumptions are invaluable in the proper design of , it is absolutely essential that a design engineer knows how and why parts fail so that reliable machines which require minimum maintenance can be , a failure can be serious, such as when a tire blows out on an automobile traveling at high the other hand, a failure may be no more than a example is the loosening of the radiator hose in the automobile cooling consequence of this latter failure is usually the loss of some radiator coolant, a condition which is readily detected and type of load a part absorbs is just as significant as the speaking, dynamic loads with direction reversals cause greater difficulties than static loads and, therefore, fatigue strength must be concern is whether the material is ductile or example, brittle materials are considered to be unacceptable where fatigue is general, the design engineer must consider al
