汉译英 我把分全压上了
空气压缩机是气源装置中的主体,它是将原动机的机械能转换成气体压力能的装置,是压缩空气的气压发生装置.空气压缩机的种类很多,按工作原理可分为容积式压缩机,往复式压缩机,离心式压缩机,本次所设计的空压机为容积式压缩机中的L型.容积式压缩机的工作原理是压缩气体的体积,使单位体积内气体分子的密度增加以提高压缩空气的压力.
文章主要介绍了压缩机的总体结构设计、热力学计算、动力学计算、气阀的设计计算和排气量的调节设计.其中总体结构的选择包括机器型式的选择、运动机构的结构及选择、列数的确定及各级气缸在列中的排列、压缩机转数和行程确定和压缩机驱动等.热力学计算主要内容有确定各级名义压力和温度、确定排水系数和吸水系数、确定气缸行程容积、确定气缸直径、计算活塞力等.在排气量的调节方面包括调节方式的分析选择、调节的结果分析和排气量的复核等方面.最后进行了空气压缩机使用寿命的初步探讨和如何提高空压机使用寿命的途径.

Answer 1

The air compressor is mad in the source installment the main body,it is transforms prime mover's mechanical energy the gas pressure energy the installment,is the compressed air barometric pressure has the installment.Air compressor's type are many,may divide into the volume type compressor according to the principle of work,reciprocating compressor,the centrifugal gas compressor,air compressor's for volume type compressor in L which this time designs.The volume type compressor's principle of work is the pressure gas volume,makes in the unit volume the gas member density to increase enhances the compressed air the pressure.The article mainly introduced compressor's gross structure design,thermodynamics computation,dynamics computation,air valve's design calculation and the air displacement adjustment design.And gross structure choice including machine pattern choice,motion structure and choice,enumeration definite and all levels of air cylinder's in row arrangement,compressor rotation and traveling schedule determination and compressor actuation and so on.The thermodynamics computation primary coverage has determination all levels of nominal pressures and the temperature,the determination freeness number and the coefficient of moisture absorption,the determination air cylinder stroke volume,the determination cylinder bore,the computation piston force and so on.In the air displacement adjustment aspect including accommodation mode's analysis choice,the adjustment result analysis and the air displacement reexamines and so on aspects.How finally has carried on the air compressor service life preliminary discussion and to enhance the air compressor service life the way.
