过程装备与控制工程专业英语————————————————————————————————作者：————————————————————————————————日期：过程装备与控制工程专业英语学院：化学化工学院1.Static Analysis of Beams⑴ A bar that is subjected to forces acting trasverse to its axis is called a beam. In this section weconsider only a few of the simplest types of beams, such as those shown in Flag.1.2. In every instance it is assumed that the beam has a plane of symmetry that is parallel to the plane of the figure itself. Thus ， the cross section of the beam has a vertical axis of symmetry .Also,it is assumed that the applied loads act in the plane of symmetry ,and hence bending of the beam occurs in that plane. Later we will consider a more general kind of bending in which the beam may have an unsymmetrical cross section.⑵ The beam in Fig.1.2, with a pin support at one end and a roller support at the other, is calleda simply support beam ,or a simple beam . The essential feature of a simple beam is that both ends of the beam may rotate freely during bending, but the cannot translate in lateral direction. Also ,one end of the beam can move freely in the axial direction (that is, horizontal). The supports of a simple beam may sustain vertical reactions acting either upward or downward .⑶ The beam in Flg.1.2(b) which is built-in or fixed at one end and free at the other end, iscalled a cantilever beam. At the fixed support the beam can neither rotate nor translate, while at the free end it may do both. The third example in the figure shows a beam with an overhang. This beam is simply supported at A and B and has a free at C.⑷ Loads on a beam may be concentrated forces, such as P1 and P2 in Fig.1.2(a) and (c), ordistributed loads loads, such as the the load q in Fig.1.2(b), the intesity. Distributed along the axis of the beam. For a uniformly distributed load, illustrated in Fig.1.2(b),the intensity is constant; a varying load, on the other hand, is one in which the intensity varies as a function of distance along the axis of the beam.⑸ The beams shown in Fig.1.2 are statically determinate because all their reactions can bedetermined from equations of static equilibrium. For instance ,in the case of the simple beam supporting the load P 1 [Fig.1.2(a)], both reactions are vertical, and tehir magnitudes can be found by summing moments about the ends; thus,we findL a L P R A )(1-= LL P R B 1= The reactions for the beam with an overhang [Fig.1.2 (c)]can be found the same manner.⑹ For the cantilever beam[Fig.1.2(b)], the action of the applied load q is equilibrated by avertical force RA and a couple MA acting at the fixed support, as shown in the figure. From a summation of forces in certical direction , we include thatqb R A =， And ,from a summation of moments about point A, we findM，The reactive moment MA acts counterclockwise as shown in the figure.⑺ The preceding examples illustrate how the reactions(forces and moments) of staticallydeterminate beams requires a considerition of the bending of the beams , and hence this subject will be postponed.⑻ The idealized support conditions shown in Fig.1.2 are encountered only occasionally inpractice. As an example ,long-span beams in bridges sometimes are constructionn with pin and roller supports at the ends. However, in beams of shorter span ,there is usually some restraint against horizonal movement of the supports. Under most conditions this restraint has little effect on the action of the beam and can be neglected. However, if the beam is very flexible, and if the horizonal restraints at the ends are very rigid , it may be necessary to consider their effects.⑼ Example Find the reactions at the supports for a simple beam loaded as shown infig.1.3(a ). Neglect the weight of the beam.⑽ Solution The loading of the beam is already given in diagrammatic form. The nature of thesupports is examined next and the unknow components of reactions are boldly indicated on the diagram. The beam , with the unknow reaction components and all the applied forces, is redrawn in Fig.1.3(b) to deliberately emphasiz this important step in constructing a free-body diagram. At A, two unknow reaction components may exist , since roller. The points of application of all forces are carefully noted. After a free-body diagram of the beam is made, the equations of statics are applied to abtain the sollution.∑=0x F ，R Ax =0∑+=0A M，2000+100（10）+160（15）—R B =0，R B =+2700lb ↑ ∑+=0B M,RAY(20)+2000—100（10）—160（5）=0，RAY=—10lb ↓ Check ：∑+↑=0FX ，—10—100—160+270=0 ⑾ Note that ∑=0x F uses up one of the three independent equations of statics, thus onlytwo additional reaction compones may be determinated from statics. If more unknow reaction components or moment exist at the support, the problem becomes statically indeterminate.⑿ Note that the concentrated moment applied at C enters only the expressions for summationmoments. The positive sign of RB indicates that the direction of RB has been correctlyassumed in Fig.1.3(b). The inverse is the case of RAY ,and the vertical reaction at a is downward. Noted that a check on the arithmetical work is available if the caculations are made as shown.横梁的静态分析⑴ 一条绕其轴水平放置的棒就是所谓的横梁，本章节我们将研究最简单的横梁模型形式，如图1.2所示。

######Manufacturing Engineering Processes1.Classification of Manufacturing ProcessesThe following table shows the classification of manufacturing engineering processes used in shaping materials. Note that only typical examples are mentioned in the table.2.Examples of Manufacturing ProcessesForging .Forging can be characterized as: mass conserving, solid state of work material (metal), mechanical primary basic process-plastic deformation. A wide variety of forging processes is used .The most common type of forging is drop forging .The metal is heated to a suitable working temperature and placed in the lower die cavity .The upper die is then lower so that the metal is forced to fill the cavity. Excess material is squeezed out between the die faces at the periphery as flash, which is removed in a later trimming process. When the term gorging is used, it usually means hot gorging. The material loss in forging processes is usually quite small. Normally, forged components require some subsequent machining, since thetolerances and surfaces obtainable are not usually satisfactory a finished product. Forging machines include drop hammers and forging presses with mechanical or hydraulic drives. Es involve simple .The machines involve simple translatory motions.Rolling Rolling can be characterized as: mass conserving, solid state of material, mechanical primary basic process-plastic deformation. Rolling is extensively used in the manufacturing of plates, sheets, structural beams, and so on. An ingot is produced in casting, and then, in several stages of rolling it is reduced in thickness, usually while hot. Since the width of the work material is kept constant, its length is increased according to the reduction. After the last hot-rolling stage, a final stage is carried out cold to improve surface quality and tolerances and to increase strength. In rolling, the profiles of the rolls designed to produce the desired geometry.Powder Compaction Powder compaction can be characterized as; mass conserving, granular state of material, mechanical primary basic process-flow and plastic deformation. In this context, only compaction of metal powder is mentioned, but generally compaction of molding sand, ceramic materials, and so on, also belong in this category.In the compaction of metal powders, the die cavity is filled with a measured volume of powder and compacted at pressures typically around 500N/mm2. During this pressing phase, the particles are packed together and plastically deformed. Typical densities after compaction are 80% of the density of the solid material. Because of the plastic deformation, the particles are”welded” together, giving sufficient strength to withstand handling. After compaction, the components are heat-treated—sintered—normally at 70%~80% of the melting temperature of the material. The atmosphere for sintering must be controlled to prevent oxidation. The duration of the sintering process varies between 30 min and 2h. The strength of the components after sintering can, depend on the material and the process parameters closely approach the strength of corresponding solid material.The die cavity, in the closed position, corresponds to the desired geometry. Compaction machinery includes both mechanical and hydraulic presses. The production rates vary between 6 and 100 components per minute.加工工艺过程1.加工工艺过程的分类2.锻造工艺过程分类锻造锻造过程的特性可表述如下，质量守恒，工作材料为固态，力学基本过程为塑性变形过程。

Heat exchangers are equipment primarily for transferring heat between hot and cold have separate passages for the two streams and operate most versatile and widely used exchangers are the shell-and-tube types but various plate and other types are valuable and economically competitive or superior in some other types will be discussed briefly but most of the space following will be devoted to the shell-and-tube types primarily because of their importance but also because they are most completely documented in the they can be designed with a degree of confidence to fit into a other types are largely proprietary and for the most part must be process designed by their manufacturers.Plate-and-Frame Exchangers Plate-and-frame exchangers are assemblies of pressed corrugated plates on a frame. Gaskets in grooves around the periphery contain the fluids and direct the flows into and out of the spaces between the spacing and the presence of the corrugations result in high coefficients on both sides several times those of shell-and tube equipment and fouling factors are accessibility of the heat exchange surface for cleaning makes them particularly suitable for fouling services and where a high degree of sanitation is required as in food and pharmaceutical pressures and temperatures are limited by the natures of the available gasketing materials with usual maxima of 300 psig and 400 F.Since plate-and-frame exchangers are made by comparatively few concerns most process design information about them is proprietary but may be made available to serious factors and heat transfer coefficients vary with the plate spacing and the kinds of costs per unit of heat transfer are said to be lower than for shell-and-tube stainless steel construction the plate-and-frame construction cot is 50%-70% that of the shell-and-tube.Spiral Heat Exchangers In spiral heat exchangers the hot fluid enters at the center of the spiral element and flows to the periphery; flow of the cold liquid is countercurrent entering at the periphery and leaving at the transfer coefficients are high on both sides and there is no correction to the log mean temperature difference because of the true countercurrent'action. These factors may lead to surface requirements 20% or so less than those of shell-and-tube exchangers. Spiral types generally may be superior with highly viscous fluids at moderate pressures.Compact (Plate-Fin) Exchangers Compact exchangers are used primarily for gas they have surfaces of the order of 1200 m2 /m3 corrugation height mm corrugation thickness mm and fin density 230-700 fins/ large extended surface permits about four times the heat transfer rate per unit volume that can be achieved with shell-and-tube have been designed for pressiIres up to 80 atm or close spacings militate against fouling compact exchangers are used in cryogenic services and also forheat recovery at high temperatures in connection with gas mobile units as in motor vehicles compact exchangers have the great merits of compactness and light kind of arrangement of cross and countercurrent flows is feasible and three or more different streams can be accommodated in the same drop heat transfer relations and other aspects of design are well documented.Air Coolers In such equipment the process fluid flows through finned tubes and cooling air is blown across them with fans. The economics of application of air coolers favors services that allow 25-40 1" temperature difference between ambient air and process the range above 10 Mbtu/l air coolers can be e conomically competítíve with watercoolers when water of adequate quality is available in su Hicient amountDouble-Pipe Exchangers This kind of exchanger consísts of a central pipe supported withín a larger one by packíng glands. The straight length is limited to a maximum of about 20 ft;otherwise the center pipe wi1l sag and cause poor distribution in the is customary to operate with the high pressure high temperature high density and corrosive fluid in the inner pipe and the less demanding one in the annulus. The inner surface can be provide with scrapers as in dewaxing of oils or crystallization from longitudinal fins in the annular space can be used to improve heat transfer with gases or viscous greater heat transfer surfaces are needed several double-pipes can be stacked in any combination of series or parallel.Double-pipe exchangers have largely lost out to shell-and-tube units in recent may be worth considering in these situations:1. When the shell-side coefficient is less than half that of the tubeside;the annular side coeHicient can be made comparable to the tube side.2. Temperature crosses that require multishell shell-and-tube units can be avoided by the inherent true countercurrent flow in double pipes.3. High pressures can be accommodated more economically in the annulus than they can in a larger diameter shell.4. At duties requiring only 100~200 sqft of surface the double-pipe may be more economical even in comparison with off-the-shell unts.Shell-and-Tube Exchangers This type of exchangers will be discussed in the following section.(Selected from: Stanley Chemical Process Equiment Butterworth Publishers 1988.)Words and Expressionsn.通道，通过a.多用途的，通用的a.专利的，私有的v.成波纹状，起波纹;corrugation nn.沟，槽n.系数n.密封垫片v.弄脏，堵塞;fouling factor 污垢系数n.卫生a.制药的；药物的n. ; a.逆流n.翅片;v.装翅片v.妨碍，起作用a.冷冻的，低温的n.恢复，回收，再生n.填料盖，密封套v.下垂，下沉n.环状空间; annular a环形的.v.脱蜡n.结晶，结晶体n.堆积，烟囱α.内在的，固有的v.调节，适度，容纳Unit 19 换热器的种类换热器起初是为了在热流和冷流中传热。

Unit 13 Principles of Heat TransferPractically all the operations that are carried out by the chemical engineer involve the production or absorption of energy in the form of heat. The laws governing the transfer of heat and the types of apparatus that have for their main object the control of heat flow are therefore of great importance.实际上，所有的由化学工程师进行的操作都要涉及热量的产生和吸收。

因此，控制传热的定律和以控制热流为主要目的的仪器类型都是很重要的。

1. Nature of Heat FlowWhen two objects at different temperatures are brought into thermal contact, heat flows from the object at the higher temperature to that at the lower temperature. The net flow is always in the direction of the temperature decrease. The mechanisms by which the heat may flow are three, conduction, convection, and radiation.当两种不同温度的物体开始接触后，热流就会从高温物体传给低温物体。

净热流总是随着温度降低的方向。

传热的机理通常分三种：热传导，热对流，热辐射。

Reading Material 16Pressure Vessel Codes①History of Pressure Vessel Codes in the United States Through the late 1800s and early 1900s, explosions in boilers and pressure vessels were frequent. A firetube boiler explosion on the Mississippi River steamboat Sultana on April 27, 1865, resulted in the boat's sinking within 20 minuted and the death of 1500 soldiers going home after the Civil War. This type of catastrophe continued unabated into the early 1900s. In 1905, a destructive explosion of a firetube boiler in a shoe factory in Brockton, Massachusetts, killed 58 people, injured 117 others, and did $400000 in property damage. In 1906, another explosion in a shoe factory in Lynn, Massachusetts, resulted in death, injury, and extensive property damage. After this accident, the Massachusetts governor directed the formation of a Board of Boiler Rules. The first set of rules for the design and construction of boilers was approved in Massachusetts on August 30, 1907. This code was three pages long.②In 1911, Colonel E. D. Meier, the president of the American Society of Mechanical Engineers, established a committee to write a set of rules for the design and construction of boilers and pressure vessels. On February 13, 1915, the first ASMEBoiler Code was issued. It was entitled "Boiler Construction Code, 1914 Edition". This was the beginning of the various sections of the ASME Boiler and Pressure Vessel Code, which ultimately became Section 1, Power Boilers.③The first ASME Code for pressure vessels was issued as "Rules for the Construction of Unfired Pressure V essels", Section Ⅷ, 1925 edition. The rules applied to vessels over 6 in. indiameter, volume over 1.5 3ft, and pressure over 30 psi. In December 1931, a Joint API-ASMECommittee was formed to develop an unfired pressure vessel code for the petroleum industry. The first edition was issued in 1934. For the nest 17 years, two separated unfired pressure vessel codes existed. In 1951, the last API-ASME Code was issued as a separated document. In 1952, the two codes were consolidated into one code----the ASME Unfired Pressure Vessel Code, Section Ⅷ. This continued until the 1968 edition. At that time, the original code became Section Ⅷ, Division 1, Pressure Vessels, and another new part was issued, which was Section Ⅷ, Division 2, Alternative Rules for Pressure Vessels.④The ANSI/ASME Boiler and Pressure Vessel Code is issued by the American Society of Mechanical Engineers with approval by the American National Standards Institute (ANSI) as an ANSI/ASME document. One or more sections of the ANSI/ASME Boiler and Pressure Vessel Code have been established as the legal requirements in 47 states in the United Stated and in all provinces of Canada. Also, in many other countries of the world, the ASME Boiler and Pressure Vessel Code is used to construct boilers and pressure vessels.⑤Organization of the ASME Boiler and Pressure Vessel Code The ASME Boiler and Pressure Vessel Code is divided into many sections, divisions, parts, and subparts. Some of these sections relate to a specific kind of equipment and application; others relate to specific materials and methods for application and control of equipment; and others relate to care and inspection of installed equipment. The following Sections specifically relate to boiler and pressure vessel design and construction.Section ⅠPower Boilers (1 volume)Section ⅢDivision 1 Nuclear Power Plant Components (7 volumes)Division 2 Concrete Reactor Vessels and Containment (1 volume)Code Case Case 1 Components in Elevated Temperature service (in Nuclear Code N-47Case book)Section ⅣHeating Boilers (1 volume)Section ⅧDivision 1Pressure Vessels (1 volume)Division 2 Alternative Rules for Pressure Vessels (1 volume)Section ⅩFiberglass-Reinforced Plastic Pressure Vessels (1 volume)⑥A new edition of the ASME Boiler and Pressure Vessel Code is issued on July 1 every three years and new addenda are issued every six months on January 1 and July 1. The new edition of the code becomes mandatory when it appears. The addenda are permissive at the date of issuance and become mandatory six months after that date.⑦Worldwide Pressure Vessel Codes In addition to the ASME Boiler and Pressure Vessel Code, which is used worldwide, many other pressure vessel codes have been legally adopted in various countries. Difficulty often occurs when vessels are designed in one country, built in another country, and installed in still a different country. With this worldwide construction this is often the case.⑧The following list is a partial summary of some of the various codes used in different countries:Australia Australian Code for Boilers and Pressure Vessels, SAA Boiler Code (Series AS 1200):AS 1210, Unfired Pressure Vessels and Class 1 H, Pressure Vessels of Advanced Design and Construction, Standards Association of Australia.France Construction Code Calculation Rules for Unfired Pressure Vessels, Syndicat National de la Chaudronnerie et de la Tuyauterie Industrielle (SNCT), Paris, France.United Kingdom British Code BS. 5500, British Standards Institution, London, England.Japan Japanese Pressure V essel Code, Ministry of Labour, published by Japan Boiler Association, Tokyo, Japan; Japanese Standard, Construction of Pressure Vessels, JIS B 8243, published by the Japan Standards Association, Tokyo, Japan; Japanese High Pressure Gas Control Law, Ministry of International Trade and Industry, published by The Institution for Safety of High Pressure Gas Engineering, Tokyo, Japan.Italy Italian Pressure Vessel Code, National Association for Combustion Control (ANNCC), Milan, Italy.Belgium Code for Good Practice for the Construction of Pressure Vessels, Belgian Standard Institute (IBN), Brussels, Belgium.Sweden Swedish Pressure Vessel Code, Tryckkarls kommissioner, the Swedish Pressure Vessel Commission, Stockholm, Sweden.压力容器准则①美国的压力容器规范历史在19世纪和20世纪初期，锅炉和压力容器频繁发生爆炸事件。
