一、瓷砖维修教程?

1.瓷砖污渍维修如果瓷砖脏了,需要先确定是什么污渍。如果是水泥或者表面其他污渍,可以用弱酸去除。如果是渗入瓷砖小孔的污渍,可以选择专业的清洁剂。(注意:不能破坏瓷砖的光泽,渗漏清理干净后,需立即做高质量的防污染处理,防止砖面再次渗漏)

2.瓷砖发黄维修如果瓷砖上有胶水或粘性污垢,可以用中性清洁剂和百洁布擦拭。对玻化砖重新打蜡,必须在表面洒上不含水的除蜡剂,10-15分钟后,地面要用水湿润,以去除旧蜡。清洁后,按照正常打蜡程序进行维护。(注意:并不是所有的瓷砖都需要打蜡,如果发现玻化砖表面变黄,立即打蜡,会使打蜡的玻化砖失去光泽)

3.瓷砖边角空鼓如果发现瓷砖边缘出现空鼓,可对边缘空鼓的部分进行浇灌处理(将瓷砖之间缝隙用小铲子砸开,然后把水泥兑水灌到缝隙里,空鼓地方会自动吸进去,直到灌满灌完凝固),避免整体更换。瓷砖维修

4.瓷砖局部空鼓墙地面的瓷砖出现少量的局部空鼓,如在不影响橱柜.镜柜.花洒和热水器等家具家电安装稳固的情况下,可以不予处理,但若是对安装和日常生活造成影响,建议把这局部的瓷砖敲掉重新铺贴。

5.瓷砖脱落维修瓷砖脱落的问题其实很好解决,旧的瓷砖还没有破损的情况,可以先把墙面和瓷砖上的泥沙清洗干净,提前把瓷砖润湿这样更容易附着,重新涂上泥浆就可以贴上了。瓷砖脱落维修

6.瓷砖开裂维修瓷砖开裂只需要买一些瓷砖填缝剂就可以修护。而且填缝剂有很多花色可以自我挑选,填补之后瓷砖的效果可能会更好。到了冬季温度较低,如果瓷砖脱瓷会难处理一些,所以这种情况只能换新。

7.瓷砖松动维修瓷砖松动可以通过灌浆的方法来处理,将胶水和水泥浆搅拌在一起,从瓷砖的空气中渗进去,一直渗到瓷砖的底部,这样松动的瓷砖就固定住了,我们在胶水和水泥浆干之前用湿布将多余的污渍擦掉就可以了。

二、吉他维修教程?

一:吉他维修教程

首先要看吉他碰的情况,坑有多深,破损程度。如果是轻来轻去的小坑,没必要大动干戈。用细砂纸慢慢打磨一下 ,然后再涂点颜料,就可以了。如果是破了一个洞,那就要进行修补一下了。先把这个洞,用锉刀锉圆了,找一块同样的材料用胶粘上,打磨平整,也可以用贴图,装饰一下。当然如果太厉害,那就要送到乐器修理厂,维修了

三、空调维修教程?

空调是现代生活中不可缺少的一部分,它提高了人们的生活水平,使人们在适宜的温度下生活。但是做为家用电器,长时间的使用,也难免会出现故障,那么出现故障该怎么办呢?本文就教教大家怎么处理。

空调基础知识

核心部件

空调器的制冷(制热)系统由压缩机、冷凝器、毛细管(或电子膨胀阀)、蒸发器四大部分组成。分体式空调器中,这4大部件分为室内机和室外机两部分。室外机有压缩机、冷凝器、毛细管(或电子膨胀阀)3大制冷(制热)部件,室内机只有1只蒸发器,它们之间用管路、截止阀来连接,从而成为一个完整的制冷(制热)系统。

压缩机

将气体压缩,将低压气体变成高压气体,常见的有涡旋式压缩机、转子式压缩机,为制冷剂提供从高温环境吸热、向高温环境放热的能量,帮助制冷剂循环顺利进行。

冷凝器

将制冷剂由气体冷凝变成液体,放出热量。

节流装置

将高压液体变成低温低压液体,常见的有毛细管和膨胀阀,制冷剂压力越低,沸点越低,节流装置的作用就是将制冷剂的压力降低到制冷剂对应的沸点比制冷时室内温度(需要从室内吸热),制热时的室外温度低(需要从室外吸热),保证制冷剂能从空气吸热,正常蒸发。

蒸发器

将制冷剂由液体蒸发变成气体,吸收热量。

循环原理:

制冷和制热原理

制冷

空调制冷时,制冷剂先经过压缩机变成高压气体;然后经过室外机换热器(冷凝器)冷凝放热变成高压液体;然后高压液体经过节流装置,会变成低温低压的液体;然后经过室内机换热器(蒸发器)蒸发吸热变成低温低压的气体,最后再回到压缩机。

制热

空调制热时,制冷剂先经过压缩机变成高压气体,然后会先经过室内机换热器(冷凝器)冷凝放热变成高压液体;然后高压液体经过节流装置,会变成低温低压的液体;然后经过室外机换热器(蒸发器)蒸发吸热变成低温低压的气体,最后再回到压缩机。

注意制冷制热时,制冷剂流向是不同的,制冷时先流过室外机换热器,此时室外机是冷凝器,室内机是蒸发器;制热时,制冷剂先流过室内机换热器,此时室内机是冷凝器,室外机是蒸发器。制冷制热不同状态时,空调会通过四通阀改变制冷剂的流向。上图红色方框内为四通阀。如果没有四通阀,空调只能实现单一制冷或者制热,不能冷热切换。

检修思路

空调检修遵循由室内到室外再到中间,先易后难。要想电路故障检修具体和简单化,就要在检修时把室内与室外电路、主电路与控制电路故障区别开来。

控制与主电路故障

1、对于压缩机频繁开停故障,可通过测量空调器负载电压与压缩机运行电流来判断故障部位。如压缩机运转电流过大,说明故障在主电路;如压缩机运转电流正常,说明故障在控制电路。

2、对于风机运转压缩机不启动故障,可通过观察室外交流接触器是否吸合来判定故障部位。如接触器吸合而压缩机不工作,说明故障在主电路;如接触器不吸合,说明故障在控制电路。对于变频空调压机不启动,可通过检测功率模块来排除故障。

3、测量室内与室外保护元件是否正常,来判断故障区域。如测量保护元件正常,说明故障在控制电路;如测量保护元件损坏,说明故障在主电路。

4、对于压缩机不运转故障,还可通过强行按动接触器,观察压缩机是否能正常制冷。如按下接触器后压缩机能运转且制冷,说明故障在控制电路;如按下接触器压缩机过流或不启动,说明故障在主电路。(变频压缩机不能采用此法)

5、对于压缩机频繁启动故障,如摸压缩机外壳温度过高,多为主电路或压缩机本身故障。

6、对于变频空调来说,可以通过空调器的故障指示灯来进行判断,如功率模块、通讯故障等。

室内与室外电路故障

1、有输入与输出信号线的空调器,可以使用短接方法来进行判断。如采用上述方法后空调器能恢复正常,说明故障在室外机;如故障没有消除,说明故障在室内机。

2、测量室外机接线端上有无交流或直流电压判断故障部位。如测量室外接线端子上有交流或直流电压,说明故障在室外机;如测量无交流或直流电压,说明故障在室内电路。

3、对功率较大的柜式空调器可通过观察室外接触器是否吸合,来判断故障部位。如接触器吸合,说明故障在室外机;如没有吸合,说明故障在室内机。

4、对于有故障显示的空调器可通过观察室内与室外故障代码来区分故障部位。

5、对于采用串行通讯的空调器电路,可用示波器测量信号线的波形来判断故障部位。

6、对于热泵型空调器不除霜或除霜频繁,则多为室外主控电路板故障。

7、有条件也可通过更换电路板来区分室外机故障。

空调故障检修方法

1、插上电源插头,室内机电源指示灯亮,如无电源指示,说明您家的电源有故障或指示灯损坏。(下图左起第一个为电源指示灯)

2、有电源指示,用遥控器按操作键,信号发射不出去。首先,检查遥控器内的电池是否有电,然后检查电池的正负极片触点有无氧化腐蚀,若上述正常,检查遥控器内部电路板是否损坏,可将遥控器靠近一台调幅收音机,按遥控器键进行干扰试验,听收音机是否发出有“嘟嘟”声,有声说明遥控器无故障。

3、当遥控器确定无故障时,信号还是发射不出去时,可用室内机强制运行开关验证,强制运行时,室内贯流风机和室外压缩机若运转正常,制冷效果良好,则证明空调器室内机红外接收部位有故障。

4、当你使用的遥控器装上新电池使用不到一个月就不显示时,可将遥控器的后盖打开,用95%的酒精清洗一下电路板和按键触点面导电胶片,干燥后,即可排除漏电故障,遥控器液晶显示缺字也可采用这种方法。

5、变频空调器中的温度传感器起着非常重要的作用,室内机有空气温度传感器和蒸发器温度传感器;室外机有空气温度传感器,高压管路传感器和低压管路传感器,有的传感器在长期使用后发生阻值变化,使控制特性改变,(如室内机空气温度传感器阻值变大后,会引起变频器输出频率偏低),为了保证控制精度,及其相同的工作特性,确定传感器故障后,应换用原型号的产品。

6、在空调器出现故障时,如果鉴别整个控制系统是否有故障,可将室内机控制器上的开关放在“试运行”挡上,此时微处理器会向变频器发出一个频率为50Hz的信号。若此时空调器能运转,并保持频率不变工作,一般认为整个控制系统无大问题,可着重检查各传感器是否完好。如果空调器不能正常运行,说明控制系统有故障。

空调保养

1、经常清扫空调器面板和机壳的灰尘

一般使用干布擦拭。先擦拭,然后再用清水湿擦布擦除掉洗涤剂。切勿用40度以上热水、汽油、挥发性油及腐蚀性溶剂擦拭空调器面板和机壳。不应用硬毛刷刷洗空调器,以免损坏外壳,造成脱漆、褪色等。

2、定期清洗空调器的冷凝器和蒸发器盘管

可使用毛刷和吸尘器清洗盘管上的灰尘。注意在清洗时毛刷和吸尘器应沿盘管的垂直方向清扫,切勿沿水平方向清扫,以免碰坏盘管的肋片。

3、定期清洗空调器的空气过滤网

一般2至3周左右清扫一次。清扫时将过滤网抽出,用干的软毛刷刷去过滤网上的灰尘。也可用清水清洗去过滤网上的灰尘。晾干后再装入空调器使用。对灰尘较多的环境,过滤网的清洗应更经常,以免过滤网沾灰尘太多,影响空调器的通风量。

四、冰箱维修教程?

现在家家户户都离不开冰箱,冰箱对我们的生活有非常大的帮助,如果有吃不完的食物或者需要储存食物都可以存放在冰箱里,以防止食品的变质。这样既方便又容易。但是由于冰箱夜以继⽇地⼯作,有时难免会出现些故障,出现故障该怎么维修呢?

冰箱构造

维修冰箱,首先我们需要了解冰箱的构造。

家用电冰箱由箱体、制冷系统、温度控制装置三部分组成。

箱体

箱体的组成:外壳、内衬、绝热层、台面。

箱体的基本作用是绝热,绝热性能的优劣直接关系到箱体的保温性能。

箱体的隔热功能主要是从以下几个方面来实现的:

1、外壳与内衬之间填充绝热材料。

2、箱门装有磁性密封条防止冷气外漏和热空气侵入。

3、箱顶的顶板下面垫有高密度聚苯乙烯泡沫板,起隔热作用。

制冷系统

制冷系统组成:压缩机、冷凝器、蒸发器、毛细管。

制冷系统自成一个封闭的循环系统。其中蒸发器安装在电冰箱内部的上方,其他部件安装在电冰箱的背面。

工作原理:系统里充灌了一种叫“氟里12(CF2Cl2,国际符号R12)”的物质作为制冷剂(氟利昂类包括氟利昂12和氟利昂11等等是一般传统的制冷剂,现在更多的是新兴的无氟制冷剂如R600a、R404a等,不过制冷原理是一样的)。氟里昂12在蒸发器里由低压液体汽化为气体,吸收冰箱内的热量,使箱内温度降低。变成气态的氟里昂12被压缩机吸入,靠压缩机把它压缩成高温高压的气体,再排入冷凝器。在冷凝器中气态的氟里昂12不断向周围空间放热,逐步液化成液体。这些高压液体必须流经毛细管,节流降压才能缓慢流入蒸发器,维持在蒸发器里继续不断地汽化,吸热降温。就这样,冰箱利用电能做功,借助制冷剂的物态变化,把箱内蒸发器周围的热量搬送到箱后冷凝器里去放出,如此周而复始不断地循环,以达到制冷目的。

内部汽化吸热 → 外部液化放热→ 箱内温度降低

温度控制装置

冰箱的温度控制装置叫温度控制器。它的主要作用是当箱内温度过高时接通压缩机,使制冷系统工作,从而使箱温降下来,当箱温降至要求的温度时,使压缩机断电。

故障检测方法

冰箱故障的检查方法一般可分为问、看、听、摸、测试等。通过检查,综合分析判断,逐渐缩小故障范围,找出故障点。

首先问明冰箱的使用情况、故障现象及使用年限,特别是旧机器,要了解机器的故障史及以前维修后的使用情况,对曾维修过制冷系统的机器,要多留意冰堵、脏堵、混入空气、冷冻油是否变质等故障。

1、首先看蒸发器结霜的情况,在压缩机运转的情况下,如果出现蒸发器表面无霜、结不满霜或结霜不实等情况,都说明制冷系统工作不正常。

2、冰箱冷冻室结冰,说明温控器温差过大,停机时间过长等因素造成的,直冷式双门冰箱的冷藏室蒸发器总是结满霜而无结霜、化霜交替变化,说明温控器发生故障。

3、检查制冷系统中管路的各个焊接处及蒸发器表面,看是否有渗漏的痕迹,凡渗漏处都会有油渍。

4、查看压缩机回气管是否结霜,如结霜,则说明制冷剂冲入量过多,对于间冷式冰箱,如压缩机回气管结霜,还应考虑是否由于风扇不转而引起。遇到这种情况,可以打开箱门,按下门框按钮,查看风扇是否旋转。

5、查看箱门是否有缝隙。如果箱门有缝隙,则冰箱保温性能差,导致压缩机开机时间长,停机时间短,而且冰箱结霜多。

1、接通冰箱电源,如果听到启动器“叭嗒”一声,压缩机在0.2秒至0.5秒内启动,随后压缩机发出轻微而且有节奏的运转声,说明压缩机启动正常。如压缩机发出沉闷的“嗡嗡”声,而后连续听到“叭嗒”的启动器触点断开、吸合的声音,有时还带有压缩机的振动声,最后可以听到热保护器“叭”的一声响,随后切断压缩机电源。此故障可以考虑以下原因:

a、电源电压低,压缩机卡缸、抱缸轴。

b、电动机扫堂。

c、电动机绕组短路。

d、电动机启动绕组开路。

e、气路系统管路堵塞。

f、启动继电器故障等。使用排除法,确定故障原因。

2、压缩机运转时,机壳内有明显的喷气声,说明压缩机排气缓冲管断裂漏气。若压缩机机壳有破裂声,说明压缩机高、低压阀片破裂、漏气。压缩机刚停机时,听到机壳内有明显的跑气声音,说明压缩机阀板的高低压纸垫被击穿、排气减震管泄漏、阀片磨损或阀片、阀口处积碳。压缩机运转时,如果机壳发出“当当”的撞击声,说明压缩机内支撑弹簧断裂或疲劳变形。

3、高压液态制冷剂通过毛细管进入蒸发器,迅速蒸发沸腾,同时发出“嘶嘶”的气流声音,并时常伴流水的声音,属于正常现象。如果听到蒸发器内有“叽叽”声,或者有断断续续的憋气声,故障通常为脏堵、油堵或者冰堵。周期性较长的断续喷气声一般为冰堵。若蒸发器内只有气流声,而且不结霜,说明系统内制冷剂基本漏完。

4、冰箱有时发出断断续续的噪音,往往是由于冰箱支脚落地不稳,制冷系统管路相互碰撞以及压缩机与箱体底座螺丝松动等原因引起共振造成的。

冰箱正常运行时,制冷系统各个部分的温度通过触摸,可以对制冷系统状况有个大致的判断。(制冷系统各个部分的温度还受环境温度的影响,环境温度升高时,冷凝器、过滤器、回气管和压缩机的温度明显升高,反之,上述部分的温度明显降低。)

1、压缩机运转时,触摸冷凝器上部,应很热(大于55℃)。如不热,可能是制冷系统漏气、堵塞或压缩机没有排气压力等故障。

2、正常时,触摸干燥过滤器应有热的感觉(约55℃)。如制冷系统过脏,会造成干燥过滤器温度升高,对于刚刚维修过的冰箱,如果干燥过滤器温度过高,一般为毛细管阻流偏大,制冷剂充入量过大。

3、压缩机正常工作时,触摸压缩机回气管,应没有热感(接近于环境温度)。如果温度高,说明系统少制冷剂,管路微堵或系统中混入空气。如果感觉到冷或者有露水甚至结霜时,说明制冷剂充入量过多。

4、压缩机机壳的温度一般在70℃以下。即使在夏季,冰箱首次开机时,压缩机经过连续长时间的工作,机壳温度也不超过85℃。

5、如果蒸发器上结的霜用手一摸就脱落(称为虚霜),并且压缩机回气管结满霜,说明充入的制冷剂过多或新换的毛细管过粗、过短。

6、用手触摸蒸发器表面,如果发现蒸发器结不满霜,说明系统制冷剂不足或毛细管半堵塞。

测试

通过测量冰箱的温度、压力、开机与停机比、运转电流以及压缩机的绝缘电阻和直流电阻等,对冰箱进行检查。

1、测温度

用电机温度计测量电冰箱的温度。电冰箱的温度按国家标准吸气温度为三十二摄氏度,蒸发温度为负二十三摄氏度一下,排气温度为五十五摄氏度左右,过冷温度为三十二摄氏度左右。

1、冰箱靠近墙面放置会导致冰箱发烫,也不能在冰箱的周围覆盖东西,这样都会阻碍冰箱散热,使温度上升,应该保持冰箱有足够的空间散热。

2、在使用冰箱的时候不要打开频繁,频繁的打开冰箱会让里的温度升高,加大冰箱的工作量,冰箱长期处于运转状态就会使温度更高的。这时要减少开冰箱的次数。

3、停用之后特别是在夏季温度很高的时候,冰箱要达到设定的制冷温度会需要很长时间,长时间的运转就会使冰箱的温度升高,冰箱一旦使用最好不要停用了。

2、测压力

冰箱的正常压力值在0.03~0.08mpa。

a、吸气压力过高,通常由:制冷剂充入过多、新换毛细管过短、压缩机性能*的原因引起。

b、出现吸气压力为负压时,通常由:制冷剂不足、系统内有堵塞现象、新换毛细管太细、太长。

2、测量冰箱的开机与停机之比

冰箱的开机与停机之比与它的制冷系统、保温性能、温控器性能、调节位置、环境温度、电路系统、冰箱内食品的多少以及开门次数等有着直接的关系。

3、测量工作电流

1、如果工作电流大于额定电流,说明制冷剂充入量过多,制冷系统微堵、压缩机局部短路。

2、如果工作电流小于额定电流,说明制冷系统有泄漏或系统完全堵塞。

3、测量绝缘电阻和直流电阻:(对于匝间短路不严重或匝间绝缘不良的电机绕组,用电阻测量方法很难分辨电机故障,因此只能采用测量工作电流的方法来判断)。

缺少制冷剂,或蒸发器内有沉积的冷冻机油,导致压缩机效率降低。

冰箱故障分类

电冰箱的故障可分为电气系统故障和制冷系统故障两大类。

电气系统故障分析

电气系统主要包括温控部分和压缩机电动机控制部分。由此而引起的故障现象是电冰箱接通电源后压缩机不起动和接通电源后压缩机运转不停。

1、首先用万用表欧姆挡测量冰箱电源插头的阻值。

压缩机的三个接线端子以及与起动器之间的接线情况如图所示:C——公共端、M——运行端、S——起动端。

各绕组间直流电阻值如下:运行绕组C、M两端约10.5Ω;起动绕组C、S两端约22Ω;而运行和起动绕组阻值的和即S、M端的阻值约为32.5Ω。正常时电路所有的开关触点都接通,对于重锤起动器式的冰箱,因重锤式起动器触点未通电而未接通,回路阻值为压缩机运行绕组的阻值,一般为10—20Ω左右,对于PTC起动冰箱,回路的直流电阻为起动器20Ω阻值与起动绕组串联后再与运行绕组并联,所以其电阻略小于压缩机运行绕组的阻值。

通过测得的阻值来判断电路的工作状态,阻值偏大时,要检查温度控制器、过载保护器、压缩机电动机以及线路和触点接触情况,阻值偏小时一般是短路,主要检查压缩机电动机及其线路。

  

2、要进一步判断还要对冰箱通电检查。

通电前先检查温控器开关是否正常。如温度控制器装在电冰箱的冷藏室内,当放置的环境温度低于设计温度时不会起动运转,故有的冰箱设计了冬季补偿开关,补偿开关打开后则温度控制器感温管附近的加热器开始加热,强制升温使压缩机运转,目的是牺牲冷藏室的正常温度而保证冷冻室的温度。

如果温控器内的开关都正常,而通电后压缩机不起动,可用一根导线短接重锤式起动器的两个静触点,注意导线短接时间不要太长,以不超过2s为宜,时间长将会使起动绕组烧坏。如果短接后冰箱能起动,说明起动器有故障,重锤式起动器长期起动易使触点烧坏,测量时拆下起动器,用万用表欧姆RX1挡,将两表笔插入接线柱插孔内。起动器正着放时相当于正常运转状态,即未接通,万用表测量阻值为无穷大;将起动器倒过来时相当于起动状态,万用表指示为0Ω,则说明起动器是好的。

如果用导线短接后仍不能起动,就需要检查保护器。可用短接法检查保护器,将保护器的两个接线铜片短接起来,如果冰箱能够起动运转,说明保护器有故障,可能是电热丝烧断或碟形双金属片受阻不能下翻,如果冰箱仍不能起动,则是压缩机或起动器有问题。检查时,把起动器和保护器拆下,露出电动机的三根接线柱。测每两个接线柱之间的电阻值,如正常,说明电动机绕组没有故障。如不正常,不要急于拆开压缩机,可以采用直接接通电源的方法进行检查。具体办法是:用带有电源插头的两根电源线接在M、C接线柱上,也就是运行绕组上,再用螺钉旋具作为导线同时碰触M和S端,然后把插头插入电源插座,如果电动机和压缩机没有故障,就会起动。起动2s左右,就要把螺钉旋具移开,电动机进入正常运转。如果检查压缩机能起动运转,说明电动机没有故障,故障发生在电动机外部,可能是外引线折断或接线柱接触不良,也可能是环境温度过低等。否则为压缩机故障。

制冷系统故障分析

电冰箱不制冷

电冰箱运转不停,但是不制冷,冷凝器不热,蒸发器不凉。这种故障一般出现在制冷系统。

可能原因是制冷剂泄漏,或者冰堵、脏堵,或是压缩机有故障。由于制冷系统是封闭的,所以可通过观察管路表面有无油污、用手触摸各部分的温度、耳听运行声音来检查。

1、检查管路表面是否有油污

仔细检查冷凝器、过滤器、毛细管、蒸发器;吸气管、压缩机外壳及管路结合处。如果发现有油污,说明制冷剂泄漏。这时可切开压缩机的工艺管。如果有少量的制冷剂喷出,就进一步证明是制冷剂泄漏。

如果没有油污,则需要进一步检查压缩机的温度。

2、检查压缩机的温度

用手摸压缩机,如果压缩机的温度不太高,和运转时差不多,说明管路畅通,没有堵塞现象,而可能是高压缓冲管破裂、活塞穿孔、排气阀同吸气阀短路等。这时可切开高压排气管,排出制冷剂。

3、检查压缩机开机时的情况

切断电冰箱的电源,打开箱门;使制冷系统各个部件恢复到室温。然后接通电源,电冰箱启动运转。如果开始时蒸发器结霜较好,冷凝器发热,低压吸气管发凉;由冰箱上部能听到气流声和水流声,但过一会儿,蒸发器结霜融化,只在毛细管同蒸发器结合部位结有少量霜;冷凝器不热,低压吸气管不凉,用耳朵贴近电冰箱上部听不到声音,说明出现了冰堵。这时如果用热毛巾敷在毛细管同蒸发器的结合处,又能重新制冷,则进一步证实是冰堵。

如果开机的时候不见蒸发器结霜,冷凝器不热,低压气管不凉,用耳朵贴近电冰箱上部听不到声音,则可以初步认为发生了脏堵。这时,可以切断高压排气管,排出制冷剂,用手指按住排气管,启动压缩机,如果手指感到有较大的压力,说明管路发生脏堵。

电冰箱制冷效果差

电冰箱运转不停,但箱内温度达不到要求,制冷效果差。这可能是由于使用不当或箱门关闭不严造成的。也可能是制冷系统故障引起的。一般应先检查使用情况和箱门情况,再检查制冷系统。

1、检查使用情况

首先要了解环境温度。如果高于43℃,制冷效果差一些是正常的。如果环境温度不高,要打开箱门检查。如果箱内食品太多,特别是放入了温度高的食品,食品释放出大量的热量;或者打开箱门次数太多,外界热空气不断进人箱内,或者未及时化霜等,所有这些都会使电冰箱长时间运转不停,制冷效果差。

2、检查箱门

电冰箱箱门关闭不严,热空气会从缝隙处不断进入箱内。这可能是磁性门封条失去磁性、老化变形,或是箱门翘曲造成的。

3、检查制冷系统

如果使用情况正常,箱门又能关闭严密,那么制冷效果差的故障就出在制冷系统。由于制冷系统仍能工作,因此,可能是制冷剂部分泄漏、部分冰堵或部分脏堵,也可能是压缩机内部故障。

检查的顺序是首先观察管路表面有无油污。如果有油污,说明制冷剂部分泄漏,这时可以切开工艺管,灌入适量的氟里昂制冷剂,再次启动运转。如果运转正常,证明是制冷剂部分泄漏。如果管路表面没有油污,可检查开机时的情况。如果开机时制冷正常,蒸发器结霜良好,在电冰箱上部能听到气流声和水流声,但过了一会儿制冷效果变差,只能听到微弱的气流声和流水声,说明是部分冰堵。

如果开机时制冷效果就差,用耳朵贴近冰箱上部只能听到微弱的气流声和水流声,这可能是脏堵或压缩机内部故障,需要进一步检查。这时,可切开工艺管,灌入适量的氟里昂制冷剂,并接入气压表,启动压缩机。如果气压表所示气压下降到正常值(0.06~0.08MPa)以下,说明压缩机内部没有故障,只是管路有部分脏堵。如果气压下降到正常值以上,说明压缩机性能下降,严重时需要拆开压缩机详细检查和修理。

如果制冷系统混入空气,或者制冷剂充加过多或不足,都可能影响制冷效果。

制冷系统中充加过多的制冷剂,会使过多的制冷剂在蒸发器内不能很好蒸发,液体制冷剂返回压缩机中,这样压缩机的吸气量减少,制冷系统低压端压力升高,又影响蒸发器内制冷剂的蒸发量;造成制冷能力下降。同时,过多的制冷剂会占去冷凝器的一部分容积,减少散热面积,使冷凝器的冷却效率降低,吸气压力和蒸发温度也相应提高,吸气管出现结霜现象。遇到这种情况,必须及时将多余的制冷剂排出制冷系统,否则不但不能提高降温效果,反而使压缩机有液击冲缸的危险。

制冷系统充加的制冷剂过少时,会使蒸发器的蒸发表面积得不到充分利用,制冷量降低,蒸发器表面部分结霜,吸气管温度偏高。遇到这种情况,可以补充适量的制冷剂。

冰箱的保养

定期适当保养可以延长冰箱的使用寿命。保养冰箱前务必拔下电源插头。

1、经常清理冰箱背面或底部冷凝器和压缩机上的灰尘。可使用吸尘器或毛刷除尘。注意不要用湿布去擦冷藏器和压缩机上灰尘。

2、冰箱长期停用时,应先切断电源,取出箱内一切食品,将箱内外清理干净,敞开箱门数日,使箱内充分干燥并散掉冰箱内的异味。

3、检查排水管。如果排水管堵塞,水就会漏到冰箱内。要用铁丝捅一捅排水管,除去积在排水管上的东西。

4、不要忽略门封胶条的清洗,将漂白剂用10倍的水稀释后用牙刷蘸湿清洗,最后用水将漂白剂冲去。胶条脏污易老化,会影响冰箱的密封性,增加耗电量。

5、检查振动、噪音以及压缩机的温度。运行中摸压缩机外壳,不应有明显的振动感,白天不应听到压缩机明显启动的声音。

6、注意检查电源线上是否有裂缝,防止漏电。

7、用温水或中性洗涤剂将冰箱内外清洗并擦干,敞开冰箱门通风干燥一天。

清洁冰箱外壳最好每天进行,用微湿柔软的布每天擦拭冰箱的外壳和拉手。清理内胆前先切断电源,把冰箱冷藏室内的食物拿出来。软布蘸上清水或食具洗洁精,轻轻擦洗,然后蘸清水将洗洁精拭去。拆下箱内附件,用清水或洗洁精清洗。清洁冰箱的“开关”、“照明灯”和“温控器”等设施时,请把抹布或海绵拧得干一些。内壁做完清洁后,可用软布蘸取甘油(医用开塞露)擦一遍冰箱内壁,下次擦的时候会更容易。用酒精浸过的布清洁擦拭密封条。如果手边没有酒精,用1:1醋水擦拭密封条,消毒效果很好。用吸尘器或软毛刷清理冰箱背面的通风栅,不要用湿布,以免生锈。清洁完毕,插上电源,检查温度控制器是否设定在正确位置。

七、电剪刀维修教程?

先拆除电源,再用锤子敲打转轴即可。

八、车载电源维修教程?

一:首先您需要仔细的查看电路板上面的各个元件,看这些元件的外表是否被烧糊或有电解液溢出,闻—闻有无奇怪的味道。然后您再需要再测量电源输入端的电阻值,如果电阻值小于20OkΩ,则就说明后端有局部短路现象。然后分别测量4只整流二极管正,反电阻值和两个限流电阻的阻值,看看有无短路或烧坏的。后您后再测量一下电源滤波电容是否能进行正常充放电、开关功率管是否击穿损坏等。UC3842及周围元件是否击穿,烧坏等情况。这里需要说明的是,因为是在路测量,有可能会使测量结果有误或造成误判,因此必要时可把元器件焊下来再进行测量。

二:第一,您可以用万用表测量高频脉冲变压器的各个元器件是否有损坏。当您排除了高频整流二极管击穿、负载短路的情况之后,再次测量各输出端的直流电压。如果这时您发现输出仍为零,那么则可以肯定是电源的控制电路出了故障。后您需要用万用表静态测量高频滤波电路中整流二极管及低压滤波电容是否损坏。如果您经过测量以后发现上述元器件有损坏,您此时就需要更换好新元器件,之后,一般故障即可排除。

九、华为手机维修教程?

华为手机维修

一、手机死机

  哈喽维修告诉你对于传统的电池可拆卸的智能手机,可以将电池拆下再装置上强制重启。哈喽维修告诉你对于电池不行拆卸一体机可长按启动键,在几秒后手机将自动进行重启。部分手机需按住Home键加电源键才可以进行强制重启,还有一部分手机则需按住音量和电源键强制关机。

  二、触屏失灵

  哈喽维修告诉你针对于触屏失灵问题应先将钢化膜撕开查看是否可以处理,假如屏幕无反应则需按两次开机键释放静电,尝试是否可以控制。哈喽维修告诉你如上述方法未能修复触屏则需拔掉充电器取下电池进行重启。关闭WiFi、按键音和触感反应以及精简桌面软件。

  三、手机不断重启

  哈喽维修告诉你针对这个问题首先需要排查电池是否装置稳固,一些非原装电池可能存在尺度规格不能完全吻合手机的状况。假如是因为手机装置软件或病毒的原因重启,可以先卸载不兼容软件或备份手机里重要的资料进行刷机。在安卓体系中,主动同步的意思是体系可以主动把手机的数据同步到网络服务器或云渠道,然后避免数据丢掉。假如没有谷歌账户或许不需求同步的话,可将其关闭省电省流量。
