23jvc 2.2电磁阀好坏?
先给电磁阀通上被控制的介质(带压力的液体、气体《空气》,压力值为电磁阀使用压力范围的中间值),再给电磁阀线圈通电,如果被控制介质有从通到断或从断到通的状态的变化,那么电磁阀就是好的,否则就是有问题的。
电磁阀常见故障有
1、线圈短路或断路
检测方法:先用万用表测量其通断,阻值趋近于零或无穷大,那说明线圈短路或断路。如果测量其阻值正常(大概是几十欧),还不能说明线圈一定是好的(我有一次测得一个电磁阀线圈阻值大概50欧姆,但电磁阀无法动作,更换该线圈后一切正常),请进行如下最终测试。
找一个小螺丝刀放在穿于电磁阀线圈中的金属杆的附近,然后给电磁阀通电,如果感觉到有磁性,那么电磁阀线圈是好的,否则是坏的。
处理方法:更换电磁阀线圈。
2、插头/插座有问题
故障现象:如果电磁阀是有插头/插座的那种,有可能出现插座的金属簧片问题(笔者就碰到过)、插头上接线的问题(比如将电源线接到接地线上去了)等原因无法将电源送到线圈中。
最好养成一个习惯:插头插在插座上之后把固定螺丝拧上,线圈上在阀芯杆之后把固定螺母拧上。
如果电磁阀线圈的插头配备有发光二极管电源指示灯,那么采用DC电源驱动电磁阀时即行就要接对,否则指示灯不会亮。
另外,不要将不同电压等级的带发光二级管电源指示的电源插头调换使用,这样会导致发光二极管被烧毁/电源(换用低电压等级的插头)出现短路或发光二极管发光很微弱(换用高电压等级的插头)。
如果不带电源指示灯,电磁阀线圈是不用区分极性的(不象线圈电压为直流的晶体管时间继电器以及线圈上并联有二极管/电阻泄漏回路的线圈电压为直流的中间继电器《这种中间继电器以原装小日本的居多》,需要区分极性)。
处理方法:修正接线错误、修复或更换插头、插座。
3、阀芯问题
故障现象一:在电磁阀所通介质压力正常的情况下,按下电磁阀红色的手动按钮,电磁阀都没有任何反应(压力介质没有出现通断的变化),说明阀芯一定是坏的。
处理方法:检查介质是否存在问题,如压缩空气内是否有很多积水(有时候油水分离器起的作用不是很大,特别是当管路设计不良时通到电磁阀的压缩空气会有很多积水)、所通液体介质是否有很多杂质。
然后清除电磁阀及管路中的积水或杂质。如果再不行,请维修(如果你有时间有耐心而且有必要的话@_@)或更换阀芯,或者干脆把整个电磁阀全部换掉。
故障现象二:经过检查,线圈是原配线圈而且线圈通电时磁性正常,但电磁阀依然不动作(这时电磁阀手动按钮的功能有可能是正常的),说明阀芯是坏的。
处理方法:请维修或更换阀芯,或者干脆把整个电磁阀全部换掉。
至于电磁阀阀体的维修,因为种类太多,那么多种的维修方法俺也说不了很多,这里就不再赘述了。
电磁阀故障与排除
一、电磁阀通电后不工作
检查电源接线是否不良→重新接线和接插件的连接
检查电源电压是否在±工作范围-→调致正常位置范围
线圈是否脱焊→重新焊接
线圈短路→更换线圈
工作压差是否不合适→调整压差→或更换相称的电磁阀
流体温度过高→更换相称的电磁阀
有杂质使电磁阀的主阀芯和动铁芯卡死→进行清洗,如有密封损坏应更换密封并安装过滤器
液体粘度太大,频率太高和寿命已到→更换产品
二、电磁阀不能关闭
主阀芯或铁动芯的密封件已损坏→更换密封件
流体温度、粘度是否过高→更换对口的电磁阀
有杂质进入电磁阀产阀芯或动铁芯→进行清洗
弹簧寿命已到或变形→更换
节流孔平衡孔堵塞→及时清洗
工作频率太高或寿命已到→改选产品或更新产品
三、其它情况
内泄漏→检查密封件是否损坏,弹簧是否装配不良
外泄漏→连接处松动或密封件已坏→紧螺丝或更换密封件
通电时有噪声→头子上坚固件松动,拧紧。电压波动不在允许范围内,调整好电压。铁芯吸合面杂质或不平,及时清洗或更换。

现场快速判断电磁阀好坏方法
一、首先检查是不是电磁阀电磁线圈故障?
在DCS上给二位阀给开或者关的信号,然后看电磁阀是否得失电,一般在现场听声音即可。若听不到,那线圈肯定是有问题,至于电磁阀本身是不是有问题?(下面解释)
如果电磁线圈问题,首先检查接线,看是不是有虚接,或者有短路现象,如果线路上没问题就是电磁阀线圈烧坏,可拆下电磁阀的接线,用万用表测量,如果开路,则电磁阀线圈烧坏。
原因有线圈受潮,引起绝缘不好而漏磁,造成线圈内电流过大而烧毁,因此要防止雨水进入电磁阀。此外,弹簧过硬,反作用力过大,线圈匝数太少,吸力不够也可使得线圈烧毁。
二、若线圈是好的,那就是电磁阀本身的问题。
一般可以在手动调节处用一字起由1调到0位置,使阀打开,若是能打开就说明的确是线圈的问题,换个线圈就可以了,若打不开,就拆电磁阀,看是不是阀芯卡住,或者是有杂粒堵,清洗正确应该用CCL4。
但是考虑到现场没有条件的话,可以用汽油,实在没有用水也可以,清洗后可以用现场仪表气进行吹干,拆时务必记好各部件的顺序,不注意的话,装的时候很容易出错,顺序记错就算你清洗好电磁阀,即使电磁阀已经通了也还是打不开的!
如何自学电脑?
电脑不仅能帮助我们快速完成重复性的工作,而且提供了一种休闲娱乐的方式。学电脑能够快速入门是每个新手梦寐以求的事情,但是不是每个人都能快速入门的。但是如果定制好合理计划,循序渐进,就会收到非常好的效果。
电脑的组成
一个完整的电脑由软件和硬件组成。硬件主要包括我们常见的鼠标,键盘,显示器,主机和各种储存介质,电脑的硬件如同人的躯干和四肢;而软件如同人的大脑和神经系统,软件在硬件的基础上才能工作。
基础入门
启动电脑
电脑启动就是我们常说的“开机”,也是启动操作系统的过程。开机具有一定的顺序:
1、打开显示器
2、打开主机
3、开机自检
4、启动成功
通过上述步骤启动电脑,叫做冷启动,是常规的开机步骤。此外,在特殊情况下,我们还可以通过下面两种方式启动电脑。
热启动:是指电脑处于开机的状态下,通过【开始】菜单中的【重新启动|】命令对电脑进行重新启动。
复位启动:当电脑在运行过程中出现异常而不能运行,且采用热启动失效时,可以采用复位启动方式重启电脑,方法是按下主机箱上的【复位】按钮即可。
关闭电脑
使用完电脑后,需要将其关闭。电脑的关机顺序与开机顺序正好相反。即先关主机电源,然后逐一关闭外部设备的电源。遵循正确的开关机顺序可延长电脑的使用寿命。
正确的关机方法为:在系统桌面上单击【开始】按钮,在弹出的【开始】菜单中单击【关机】按钮,电脑将停止所有程序并退出操作系统,接着系统将自动断开主机电源,然后再依次关闭显示器、音箱等外接设备即可。
如何使用键盘
键盘是用于操作计算机设备运行的一种指令和数据输入装置,也指经过系统安排操作一台机器或设备的一组功能键(如打字机、电脑键盘)。
电脑键盘由功能键区、主键区、编辑键区,数字键区和小键盘区5个区组成。其中常用操作打字是在主键区完成的。
键盘是最常用也是最主要的输入设备,通过键盘可以将英文字母、汉字、数字、标点符号等输入到计算机中,从而向计算机发出命令、输入数据等。
如何使用鼠标
鼠标,是计算机的一种外接输入设备,也是计算机显示系统纵横坐标定位的指示器,因形似老鼠而得名(港台作滑鼠)。其标准的称呼应该是“鼠标器”,英文名“Mouse”。鼠标的使用是为了使计算机的操作更加简便快捷,来代替键盘那繁琐的指令。
一般的鼠标上有左键,右键和滑轮三个部分。
计算机的储存介质
计算机的储存介质有:硬盘、U盘、光盘和软盘等。
硬盘
电脑硬盘是计算机最主要的存储设备,硬盘一般分为固态硬盘(SSD)和机械硬盘(HDD)两种。固态硬盘读写速度更快,但存储容量较小,机械硬盘存储容量较大但同容量大小,固态硬盘价格也更昂贵。
U盘
U盘是USB(USB flash disk)盘的简称,据谐音也称“优盘”。U盘是闪存的一种,故有时也称作闪盘。U盘与硬盘的最大不同是,它不需物理驱动器,即插即用,且其存储容量远超过软盘,极便于携带。
软件操作
电脑软件(Computer Software)是指计算机系统中的程序及其文档。一般来讲软件被划分为系统软件、应用软件,系统软件为计算机使用提供最基本的功能,可分为操作系统和支撑软件,其中操作系统是最基本的软件,常见的操作系统包括为微软的Windows系统。
软件的基础操作
软件的使用包括软件的下载、安装和卸载:
软件的下载
1、浏览器下载
2、软件官网下载
3、电脑管家或360软件管家等下载软件(下图为360软件管家)
软件安装
第一种就是你下载下来的是.exe文件的应用程序,这种程序一般都是安装包,就是你双击之后,会进入安装界面;第二种就是不需要安装的,你下载下来的是一个压缩文件,你只需要解压就可以使用。
电脑软件安装过程中特别要逐一择安装设置(安装盘位)的选择、流氓软件选项勾选等。
软件的卸载
控制面板—程序和功能—找到要卸载的软件—右击卸载
软件的启动
电脑软件的启动方法一般有双击,右击-打开或从开始菜单单击打开
1、一般安装软件后会在桌面创建快捷方式,直接打开。
2、若桌面没有快捷方式,可以在电脑左下角的“开始”—“程序”里面打开。
3、若“程序”里面也没有,可以打开软件的安装位置打开。
说明:第三种方法是按默认的安装路径找到的软件安装文件夹打开程序的,实际情况可以根据软件的具体安装路径选择打开。
应用软件的操作
文件操作包括如何操作打开,关闭、删除、移动、重命名和编辑文件
文件打开
文件打开方式见“如何启动软件”部分
常见不同后缀、格式文件打开方法:
.txt .doc .docx .obt 这些格式可以用微软的office打开,或者用wps打开。
mp3格式文件可以使用使用电脑自带的Media Player播放器或者其他的音乐播放器。
mp4、mpg. mpeg.等文件可以使用电脑自带的电影和电视功能或者其他视频软件打开。
文件关闭
一般软件点击右上角的“×”,再点击“确认”,即可关闭文件
文件删除
1、选中文件-右击-删除
2、选中文件-按“delete”键,即刻删除
文件移动
方法一:长按鼠标左键选中并拖动鼠标移动文件到想要的地方
方法二:右击鼠标—剪切-打开需要移动的地方-右击粘贴
文件重命名
方法一:选中文件—右击—重命名
方法二:鼠标左击—键盘F2,即可进行重命名
文件管理基础知识
硬盘分区
电脑中的文件都存放在硬盘中,而新买回来的硬盘相当于一张白纸 ,为了能够更好地使用它,需要在,白纸上划分出若干小块。然后再打上格子。硬盘分区就是这个道理,在安装操作系统之前,需要进行硬盘分区和格式化,然后才能投入使用。对硬盘进行分区后,各个分区独立使用,互不影响。在操作系统中每个分区都用一个盘符表示,如本地磁盘(C)、本地磁盘(D)等。
存储路径
文件的存储路径,就是文件在电脑硬盘中的存储位置,由硬盘分区、文件夹和子文件夹构成。其中硬盘分区的盘符为路径的第一项,是第一级目录,也叫做根目录,后面紧跟冒号和斜线(:/),文件夹和子文件夹中间则以斜线(/)隔开。
如何使用浏览器
主要介绍如何使用浏览器(以及搜索引擎)查找资料。
1、首先在浏览器中输入搜索引擎的网址,以百度为例:
2、然后就进入搜索引擎所在网页,这样才能进行搜索:
3、之后在搜索栏中输入搜索内容,可以是词语、短语也可以是句子:
4、最后点击百度一下进行搜索:
5、然后就可以得到想要的信息了:
电脑的日常维护
日常注意事项
电脑的五大要害:静电、灰尘、水、震荡、病毒是电脑的五大要害
1、防静电:防止静电损坏电脑各部分电子原件,处理办法是将电脑机箱外壳接地,尽量使用三脚电源插头。
2、防尘:防止灰尘进入电脑机箱内,使用时保持环境清洁,并定期清理电脑主机内的灰尘。
3、防水:防止液体进入电脑的任何部分,保持室内通风。不要将电脑放在湿度较大的房间使用。
4、防震:在使用的过程要防止对电脑的震荡,应将电脑平稳放置在电脑桌上,以防不小心摔落等
5、防病毒:病毒是电脑的一大要害,在日常使用中要防止病毒的进入,需要给电脑安装防病毒软件,并经常更新病毒库,经常给电脑杀毒。
显示器维护
液晶显示器最大的禁忌在于触摸液晶面板。液晶面板表面有专门的涂层,这层涂层可以防止反光,增加观看效果。而很多用户不知道这点,总是习惯于用手去摸液晶屏幕,殊不知人手上有一定的腐蚀性油脂,会轻微的腐蚀面板的涂层,时间长了会造成面板永久性的损害。这种被损坏的面板在使用中会有斑驳陆离的感觉。另外,有些人喜欢用手去压面板,觉得很有意思。这绝对是个恶劣的习惯,这样做会导致坏点和暗斑,这可是永久性的损害,绝不可修复的!
主机维护
在电脑运行过程中,机器的各种设备不要随便移动,不要插拔各种接口卡,也不要装卸外部设备和主机之间的信号电缆。如果需要作上述改动的话,则必须在关机且断开电源线的情况下进行。
不要频繁地开关机器。关机后立即加电会使电源装置产生突发的大冲击电流,造成电源装置中的器件被损坏,也有可能造成硬盘驱动突然加速,使盘片被磁头划伤。因此,这里我们建议如果要重新启动机器,则应该在关闭机器后等待10秒钟以上。在一般情况下不要擅自打开机箱,如果机器出现异常情况,应该及时上报。
数据存放在不同分区,减少磁头对某一扇区的经常读写,导致这一扇区的损坏。 建议你使用不同的媒介定期对你的重要数据进行备份,并存放在不同的地方。一个文件可以在备份盘上放一份,可以打印一份,可以刻录成光盘。
键盘、鼠标的日常维护
(1)保保持清洁 过多的灰尘会给电路正常工作带来困难,有时造成误操作,杂质落入键位的缝隙中会卡住按键,甚至造成短路。我们在清洁键盘时,可用柔软干净的湿布来擦拭,按键缝隙间的污渍可用棉签清洁,不要用医用消毒酒精,以免对塑料部件产生不良影响。清洁键盘时一定要在关机状态下进行,湿布不宜过湿,以免键盘内部进水产生短路。
(2)不将液体洒到键盘上 一旦液体洒到键盘上,会造成接触不良、腐蚀电路造成短路等故障,损坏键盘。所以我们一般不要边喝茶边坐在电脑前,这样一不小心茶可能就洒在键盘上.
电脑病毒防护
电脑一旦感染了病毒,就会出现很多症状。导致系统性能的下降,影响用户的使用,甚至造成灾难性的后果。电脑在日常的使用过程中要定期进行病毒查杀,防患于未然。常用的电脑杀毒软件有360,金山毒霸和电脑管家等等。以金山毒霸为例介绍电脑杀毒的过程。
1、打开程序主界面
2、选择杀毒方式
3、开始杀毒。程序对磁盘内容自动进行扫描,如果检测到病毒会自动进行清除,并将结果显示在扫描栏中。
4、除此之外还可以对特点的盘进行杀毒。

SF=Systemfault就是报系统故障,INTF应该是内部故障,EXTF是外部故障。你必须知道为啥报故障,你得打开硬配然后在线,然后双击CPU然后找到diagnosisbuffer,就是诊断区,然后看具体为啥报这种错误,然后进行修改。
b10ae04是什么故障码?
BAF04故障码是空气温度传感器故障或传感器引线间歇性故障 一般来说,这个故障码会出现在斯柯达机型中控空调调度器的故障中,这个传感器的作用是感受车内空气的温度并发送给空调控制器,如果出现故障会导致空调系统不能及时调整温度 解决这个问题可以先检查温度传感器的引线是否断开或松动,如果无法处理就需要到汽车维修店进行进一步检测和故障排除另外,车主可以进行简单的空调保养,如定期更换空气滤芯,定期进行检查和保养,可以有效避免出现这种故障
