二、变压吸附式干燥原理
干燥机是通过“压力变化”(变压吸附原理）来达到干燥效果。由于空气容纳水汽的能力与压力成反比，其干燥后的一部分空气（称为再生气）减压膨胀至大气压，这种压力变化使膨胀空气变得更干燥，然后让它流过未接通气流的需再生的干燥剂层（即已吸收足够水汽的干
燥塔），干燥的再生气吸出干燥剂里的水份，将其带出干燥器来达到
十一、润滑水路上各组件功能说明
A.冷却器冷却器有风冷与水冷两种方式。其中ZW775W、ZW555W为水冷，ZW225A、ZW155A为风冷。 ZW375则分水冷（ZW375W）和风冷（ZW375A）两种。
B.水过滤器水过滤器滤芯为玻璃纤维，其功能为除去润滑水中的杂质颗粒等，过滤精度为5µ。对压缩机主机有完善保护作用。水过滤器并联一压差开关，其设定压差一般为0.2Map，提示水过滤器是说明此时水过滤器滤芯需要更换。若水过滤器压差过大而未更换滤芯，则可能导致进水量不足。而引起排气高温跳机，同时也可能影响主机的正常使用寿命。
空气通过排气口输送至排气管，直到星轮齿脱离该螺槽为止。
一、空气流程空气经空气滤清器过滤后，经由阀门控制器进入压缩机主机压缩；并与润滑水混合，与水混合的压缩空气经由排气止回阀进入水气桶，在水气桶内压缩空气与水分离后经压力维持阀送入使用系统。二、空气滤清器空气滤清器为一干式纸质过滤器，内部装有压差探测器，如果控制面板上空气滤清器阻塞指示灯亮，即表示空气滤清器须进行清洁或更换。三、阀门控制器阀门控制器为一碟阀，用于压缩机的容量控制。压缩机可以根据系统实际使用压缩空气量的大小进行自动调节。当系统压力逐渐上升（未达到压力开关设定值）时，先达到压力调节阀所设定的压力，则会有少许空气通过，
4、排气温度过高，空压机自动停机（排气温度过高报警）

世界空压机排名前十的品牌

空压机排名前十的品牌是：阿特拉斯，英格索兰，寿力,德耐尔，康普艾，博莱特，昆西,复盛,日立、神钢、凌格风附前五大品牌空压机介绍：1、Atlas Copco阿特拉斯、柯普科(以下简称AC）AC是一个跨国集团，总部在瑞典，空压机生产企业只是其下属一个集团。

由于多年的不断收购,AC几乎能生产各种形式的空压机，颇负盛名.估计其在全球的占有率最高。

AC主要生产有油螺杆空压机，在全球有多个工厂，在中国无锡亦设有工厂. AC在中国国内主要依靠其分公司销售,AC在北京、上海、广州等重要城市均设有分公司。

AC最大优势在于知名度，对于重要项目能采取灵活价格.AC的劣势在于服务品质较差，服务费用高，同时对于小项目的关注不多。

AC目前是国内最赢利的无油螺杆空压机。

2、Ingersoll—Rand英格索兰(以下简称IR）IR亦是一个跨国集团，其总部设在美国,空压机生产企业只是其下属一个集团.IR亦能生产各种形式的空压机，产品种类丰富，知名度也高.IR在全球的市场占有率仅次于AC或与之不相上下.IR是最早在中国合资生产螺杆机的公司，1987年成立于上海。

1995年以前，上海IR的生产和销售非常好。

市场上的客户都等着购买螺杆机，而此时只有IR 生产螺杆机.IR主要通过分公司销售，在全国各主要城市设有分公司,如北京、沈阳、青岛、武汉、三峡、广州、上海等。

在其他地区，IR则通过经销代理商进行销售。

IR因为在中国国内建立工厂比较早，知名度比较高。

不过由于上海IR采用的是30年以前的生产技术，其品质不是很好，且已经大大影响了其销售。

过去10年中，IR在中国最赢利的产品是离心式空压机。

1997年以前，IR占有中国国内进口离心式空压机的80％的市场。

其销售人员的职责仅仅是忙于签单，带客户去美国观光而已。

IR另一个赢利的产品是移动式空压机，该产品在中国国内被广泛应用。

IR目前的优势仍然是其知名度,其劣势在于其有两套销售系统：一是远东IR,一是上海IR。

阿特拉斯Atlas-Copco空压机常见故障排除

四、螺杆式空气压缩机
压缩空气含油量高的原因：
一：油气分离器质量二：回油管或回油单向阀堵塞三：压力维持阀开启压力过低四：使用压力过低五：油的品质出现泡沫常见的压力维持阀设定在大于或者等于0.40Mpa出气，油气分离芯最好用原装的（内置的）回油管的位置有没有偏移，外置的要看一下回油管和滤网或者回油单向阀。空气压缩机压力维持阀流速过高也会产生压缩空气含油量高的情况（开启压力过低），这种情况经常出现。
· 制冷剂量过多 · 制冷系统中有空气 · 冷凝器脏 · 环境温度太高 · 风扇压力开关有故障 · 风扇电机故障 · 风扇旋转方向不正确 · 冷却水流量调节阀故障
8.故障现象：排气压力太低

Atlas copco空气压缩机基础培训材料解析

1、喷油式螺杆空压机工作原理螺杆式空气压缩机的核心部件是压缩机，是容积
式压缩机中的一种。空气的压缩是靠装置于机壳内互
相平行啮合的阴阳转子的齿槽之容积变化而达到。阴阳转子的转动使转子齿槽之间的气体不断地产生周期性的容积变化而沿着转子轴线，由吸入侧推向排出侧,完成吸入、压缩、排气三个工作过程。
三、油分离器的附属装置 1、安全阀：空压机油分罐端盖上面装有安全阀，当油分罐内的空气压力达到设定值的1.1倍时安全阀自动打开，放掉部分空气，降低油分罐内的气压。检查安全阀的方法是在压缩机满载工作时，轻拉安全阀上的泄气拉杆，若安全阀能向外排气，则视为正常。 2、压力表：油分罐上装有一个压力表，检测的是滤前压。油分
4、排气温度过高，空压机自动停机（排气温度过高报警）
1、润滑油量不足 2、润滑油量规格/型号不对 3、油过滤器堵塞 4、油冷却器堵塞或表面污垢严重 5、温度传感器故障 6、温控阀失控 7、风扇及冷却器集灰过多 8、风扇电机未运转 9、风道安装不正确
1、检查添加油 2、按要求更换新油 3、检查更换新建、件 4、检查清洗 5、更换新件 6、检查清洗、更换新件 7、坼下清洗、更换新件 8、检查电路及风扇电机 9、改正风道
空压机专题培训
1、此次培训不设复习题，所有考试内容全部在培训PPT中，员工自己总结。目的是想了解员工对培训内容的综合、理解
与掌握程度，从而达到学而能用，而不是单纯的为取得高分
而学习。 2、杜绝以往培训考核中的死记硬背现象，逐步培养员工独
立解决、分析问题的能力，使大家早日成为一名优秀的运行
保障中心员工。 3、考核预计在12月中下旬，请大家认真准备，积极应战。
6、空压机排气量低于正常要求
故障现象
可能产生的原因进气阀内的单向阀弹簧失效或单向阀密封圈损坏 1、安全阀使用时间长、弹簧疲劳 2、油分离器堵塞 3、压力控制失灵，工作压力高报警复位，一般按右上角45度双线。设备报警后先观察面板报警符号后再做处理。如果急停开关按下去时，复位报警符时，先把急停开关拔起来。
