2、压缩比:(R)压缩比是指压缩机排气和进气的绝对压力之比。

空气压缩机的常用术语
空气压缩机常用术语一、压缩介质为什么要用空气来做压缩介质?因为空气是可压缩、清晰透明的,并且输送方便(不凝结)、无害性、安全、取之不尽。
惰性气体是一种对环境不起化学作用的气体,标准压缩机能一样压缩惰性气体。
干氮和二氧化碳均为惰性气体。
空气的性质:干空气成分:氮气(N2)78.08% 氧气(O2)20.93% 二氧化碳(CO2)0.03% 密度:在0℃、760mmHg 柱时,R0=1.293kg/m3二、“级”和“段”在容积式压缩机中,每经过一次工作腔压缩后,气体便进入冷却器中进行一次冷却,这成为一“级”。
而在动力式压缩机中,往往经过两次或两次以上叶轮压缩后,才进入冷却器进行冷却,把每进行一次冷却的数个压缩“级”合称为一个“段”。
在日本把容积式压缩机的“级”称为“段”,中国个别地区、个别文献受此影响,也把“级”称为“段”。
三、压力压缩机行业中所指的压力指的是压强(P)面积上作用1N的力为1Pa,即1Pa=1N/㎡,Pa为压力基本单位,当压力数值大时可用kPa(1kPa=1000Pa)与MPa(1MPa=1000000Pa)。
Ⅰ标准大气压(atm)Ⅱ表压与绝压①用压力表测得的压力为表压力,它是容器内的压力与当地的大气压之差,是以大气压力为零点测得的压力,用P(G)表示。
②以绝对真空为零点的压力我们称为绝对压力,是容器内的压力与当地大气压之和,用P(A)表示。
表压与绝压的关系:表压+大气压=绝压通常在压缩机铭牌上给出的排气压力为表压力。
Ⅲ工作压力吸、排气压力,是指空压机吸、排气的压力压缩机首级汽缸工作腔进气法兰和末级汽缸工作腔排气法兰接管处测得的气体压力称为压缩机的吸、排气压力。
在某些场合,压缩机的排气压力也称“背压” 螺杆空压机吸、排气压力指的是整个空压机的吸、排气压力,一般说空压机的工作压力指的是排气压力。
Ⅵ空压机常用的压力单位换算1MPa(兆帕)=1000kPa(千帕)=1000000Pa(帕斯卡)1bar(巴)= 0.1MPa1atm(标准大气压)=0.1013MPa=1.013bar=760mmHg=10.33mH2O1kgf/cm2(工程公斤力)=0.981bar=0.0981Mpa1psi(Lb/in2 )=0.07031kgf/cm2=0.06893 bar=6.893kpa1MPa=145psi Psi(lb/in2 )磅/平方英寸,常用在欧美等英语区国家的产品参数上通常在空压机行业说的“公斤”是指“bar”四、压缩Ⅰ等温压缩:气体被压缩时温度始终保持恒定的压缩方法。

压缩机常见术语
压缩机常见术语压缩机常见术语1.容积流量(排气量m3/min):在所要求的排气压力下,压缩机单位时间(min)内排出的气体容积,折算到进口状态的容积值。
注:若需计算排出的气体容积,在不考虑气体温度变化的情况下,则可用排气量除以排气压力(bar)加1(标准大气压)的和求得。
以OGFD-3.0/8为例则每分钟排出的8bar压力下气体容积为:3/(8+1)=0.3332.标准容积流量(Nm3/min):压缩机单位时间内排出的气体容积折算到标准状态之值,并不计入级间分离掉的水分及抽气量。
3.标准状态:标准大气压力1.013×105Pa(760mmHg).温度15℃4.排气压力(bar):最终排出空压机的气体压力(实际是压强)。
1bar=105Pa=0.1M Pa1kg/cm2=0.98 bar5.供气温度(℃):最终排出空压机的气体温度,≤环境温度+10℃。
冷干机选用高温型较保险,犹其是风冷机组。
6.排气温度(℃):从压缩机主机口排出的气体温度(未经过冷却器)。
7.电动机额定功率(KW/HP 千瓦/匹):主电动机铭牌上标称的额定功率。
8.转速(r/min):正力采用两极电机,转速约3000 r/min;四极电机转速约1500 r/min。
9.启动方式:常规产品Y-△启动;高电压(3KV以上)机直接起动;煤矿机直接起动;另有软起动.变频起动.自藕降压起动等可选,但必须在技术协议上注明,价格变动。
10.电源:常规380V/50Hz;另有3KV/50Hz.6KV/50Hz.10KV/50Hz可选,但必须在技术协议上注明,价格相应变动,高压机同时需提供三相四线的电源以供控制电路之用;煤矿机有380V/50Hz和660V/50Hz两种可选。
11.电机防护等级:常规IP44 煤矿机:IP55 高压机:IP2312.传动方式:弹性联轴器传动,比皮带及齿轮传动效率高。
13.轴功率(KW):压缩机主轴上要求输入的功率。
活塞式制冷压缩机
活塞式制冷压缩机第一节活塞式压缩机概述一、压缩机分类1、1、按使用的工质分类分为氨压缩机、氟利昂压缩机、异丁烷压缩机等。
2、2、按气缸布置方式分类分为卧式、直立式和角度式三种类型。
如图2-1所示。
3、3、按压缩机的密封方式分类分为开启式和封闭式两大类。
4、4、按制冷量的大小分类配用电动机功率不小于0.37kW、气缸直径小于70mm的压缩机为小型活塞式制冷压缩机;气缸直径为70~170mm的压缩机为中型活塞式制冷压缩机。
5、5、按气体压缩的级数分类分为单级压缩和多级(一般为两级)压缩制冷压缩机。
如果有一台压缩机来实现两级压缩,则又称为单机双级制冷压缩机。
6、6、按活塞行程分类分为短行程和长行程两种。
二、压缩机的型号及基本参数按GB10871-1989规定,小型活塞式单级制冷压缩机的型号表示如下:开启式压缩机的基本参数规定:气缸直径为60mm、转速范围为600~1500r/min。
半封闭式压缩机基本参数规定:气缸直径为30mm\40mm\50mm\60mm,名义转速为1440r/min。
中型活塞式单级制冷压缩机的型号表示:压缩机组型号表示:小型、中型活塞式单级制冷压缩机的基本参数见表2-1和表2-2。
表2-1 小型活塞式单级制冷压缩机的基本参数表2-2 中型活塞式单级制冷压缩机的基本参数目前国内生产厂家在样本等资料上,仍习惯于沿用老的压缩机型号表示方法,即第二节第二节活塞式压缩机的基本结构和工作过程一、基本结构和名词术语1、基本结构各种活塞式制冷压缩机的制冷量、外形、制冷剂、用途等不尽相同,但其基本结构和组成的主要零部件都大体相同,即包括机体、曲轴、连杆组件、活塞组件、吸排汽组件、汽缸套组件等。
图2-2即为一台立式两缸活塞曲柄连杆式制冷压缩机的结构轴测图。
2、名词术语下面利用图2-3介绍压缩机的有关名词术语。
1.外止点(上止点):活塞在汽缸中作反复运动时,离曲轴旋转中心最远的位置,如图2-3(a)所示。
