为什么如此清晰的原因。LCD也不必关心刷新频率和闪烁，液晶单元要么开，要么关，
所以在40-60Hz这样的低刷新频率下显示的图像不会比75Hz下显示的图像更闪烁。另一方面，LCD屏的液晶单元极易出现暇疵。对1024x768的屏幕来说，每个像素都由三个单元构成，分别负责红、绿和蓝色的显示一所以总共约需 240 万个单元 (1024x768x3=2359296)。很难保证所有这些单元都完好无损。最有可能的是，其中一部分己经短路 (出现“亮点” )，或者断路(出现“黑点”)。有些顾客可能认为如此高昂的价格应该买到完美的 LCD显示屏 -很不幸这不是现实，最多能挑到暇点不特别明显的屏幕而已。

LCD显示屏包含了在CRT技术中未曾用到的一些东西。为屏幕提供光源的是盘绕在其背后的荧光管。有些时候，我们会发现屏幕的某一部分出现异常亮的线条。也可能出现一些不雅的条纹，一幅特殊的浅色或深色图像会对相邻的显示区域造成影响。此外，一些相当精密的图案(比如经抖动处理的图像)可能在液晶显示屏上出现难看的波纹或者干扰纹。另外还有一个视角或者"观察角度"的问题。LCD之所以存在视角问题，是由于它采用的是光线透射机制，会对穿过屏幕的光线进行调节。而 CRT是一种光线发射系统。对CRT来说，屏幕背后的特殊材料(荧光粉)能主动发射出光线。而在LCD中，虽然光线能穿透正确的像素，但倾斜的光线也会穿透相邻的像素，所以从正常视角之外观看时会发现颜色严重失真。
3、防眩光防反射：防眩光防反射主要是为了减轻用户眼睛疲劳所增设的功能。由于LCD屏幕的

叉车维修手册范本

叉车维修手册. 叉车常见故障的诊断排除二.叉车常见故障的维修调整总溢流阀的调整1. 卸下溢流阀的顶盖螺母，旋松锁紧背母后，将调节螺钉调到最松。

2. 低速回转油泵。

3. 货叉上放上额定载荷，将起升操纵杆扳到上升位置，旋动调节螺钉是货叉能举升载荷为准。

调整时应注意：A ：一边拧紧调节螺钉，一边紧固琐紧螺母至锁紧为止。

B：调节螺钉每旋入 1 圈产生约60公斤/厘米2压力。

液压油泵更换后的检查1. 在多路阀的进油口处安装一块油压表，量程为0~250 公斤/厘米22. 将起升和倾斜操纵杆放在中位，发动机转速控制在500～1000转/ 分，此时油压表的压力10 公斤/厘米2以下，保压10 分钟，油泵噪音是否正常。

3. 将转速提到1500~2000 转/分，无载状态下运转5分钟.4. 将总溢流阀调节螺钉放松，起升和倾斜操纵杆放在中位。

调节螺钉将压力定在30 公斤/厘米2以上。

然后以每提高20公斤/厘米2的压力为一挡，并保压 5 分钟，直至调到溢流阀所限定压力数值为止。

叉车链条松紧度的调整方法：1. 将叉车开到平坦的场地上，把叉子降到地面.2. 以滑架一侧的铰接螺栓为定位3. 将起升缸一侧的铰链螺栓调节好链节长度后，锁紧起生缸一侧的螺母。

4. 在距地面 1 米处，手指（约 5 公斤的力）推按链条，使链条的移动距离为20 毫米便可。

见右侧示意图多路换向阀外漏和漏的检查外漏的检查部位： 1. 阀块之间的密封圈 2. 滑阀的密封圈 3. 连接螺栓部漏的检查：1. 在叉子上放上额定载荷，起升到 1 米的高度，使门架前倾3~4℃，然后熄灭发动机。

2. 卸下多路阀回油管，将排除的油装入器皿中，其标准为： 1 分钟排出的油不超过20 毫升。

或门架自然下滑量不大于80mm/10min，前倾不大于8.7mm/10min（油缸无外泄露情况下）。

注意：载荷在滑架上栓牢固定，以防滑落离合器打滑和分离不开的判断及更换方法一.离合器打滑的判断方法：1. 拉紧手刹使车轮制动。

¾工作后，先把电源切断，然后清洁焊咀，再加上一层新焊锡以保护烙铁头。

2、焊接注意事项¾烙铁温度可控制在430°左右。

¾清除锡渣时尽量避免使用吸锡器防止翘皮。

¾焊接时，请勿用力过大，否则会使焊咀变形。

¾焊接时间最好控制在3秒以内，防止良品元件损坏。

3、所有接触到LCD电路板的设备均要有良好的接地三：拆除贴片元件要点：1、在不良元件两端堆加焊锡。

2、可适量加点助焊剂。

3、用烙铁头的扇面直接接触贴片元件使焊锡熔化。

其中Y1=100.21 Y2=100.25为左右油缸(滑块)的位置,
Y-轴状态=1 ---------------表明滑块的状态为停在“上死点”。
Y轴状态的变化及定义如下:
Y-轴状态=2 ---------------滑块处于“快下”状态。
输入密码25789进入参数页面
进入X轴参数的反馈页面“参考点位置”
假设X=实际尺寸-理论尺寸
那么新参考点=原参考点+X
将参考点改完后保存并重启数控系统，其他辅助轴的修正方法同X轴。
b. Y轴参考点的校正方法：
1）用一块板材放在下模上，在数控系统操作页面输入正确的板厚、上下模、折弯角度180°
2）踩下脚踏开关，滑块运行至下死点，此时板料应该正好被压住，不能被抽出，也不能有压痕。此时参考点是正确的。
滑块向上运动寻找Y1、Y2轴的参考点，当滑块分别经过左右光栅尺的REF点后，滑块将停在上死点。Y轴的参考点寻找完成。
后挡料机构往后运动寻找X轴的参考点，运动到后RSD开关处等待其它轴（X1轴、R轴、Z1轴、Z2轴）寻找到参考点并定位完成后，后挡料X轴反向向前寻找到参考点并定位到手动页面中所编程的X值。假如后挡料只配置了X轴时，后挡料将直接反向寻找到参考点并定位完成。

科诺电磁炉维修服务手册

科诺电磁炉维修服务手册（05版）编制：审核：批准：目录一．前言二．电磁炉的工作原理三．电磁炉各主要环节原理说明四．整机原理框图五．电磁炉内部结构六．故障检查及流程七．维修方法及注意事项八. 故障检查流程图九．故障代码的检修十．原理图一、前言本维修手册适用于科诺电磁炉各款机型（除开关电源外）。

电磁炉原理上均基本相同，故主板电气原理相同，操作面板和输出功率有区别。

功率不同的电磁炉所采用的IGBT型号也不同。

维修时不能搞错。

二、电磁炉的工作原理电磁炉工作原理是基于电磁感应加热的原理。

由于电磁炉没明火所以从安全性的角度出发它优于电阻丝加热的普通电路和燃气灶具，不容易引起火灾或瓦斯中毒的危险。

它的基本原理是先将交流电整流成直流电，随后再将直流电变成高频交流电（AC-DC-AC）高频交流电的频率通常在20KHZ~30KHZ之间，我们把高频交流电送入一扁平的线圈，使之产生高频交流电磁场。

如果把铁磁性的锅具至于该磁场中间那么磁场就会在锅底产生涡流而变成热量，将锅底加热。

显而易见前提是锅底本身必须由不锈钢或铁制成。

由于加热只能在锅底产生，可以不容易被灼伤，也不会将周围空气加热或者因风而使锅底熄灭因此热效率明显高于用明火加热的方式，安全性也强于其它炉子。

微电脑电磁炉是在控制电路中加入了主控CPU芯片，使之电磁炉使用更为方便可靠。

例如CPU芯片可以很圆满的完成过电压、过电流、过热、定时、恒功率加热，以及大功率开关元件的保护等的功能。

由直流电变为高频交流通常称为逆变。

逆变主要由大功率晶体管（GTK）或IGBT等电力电子器件来完成。

三、磁炉主要环节的工作原理说明1．输入部分：压敏电阻器（ZR）主要用以防止过高的浪涌电压进入电磁炉造成炉子损坏。

通常选用430~470V等级的电压。

一旦发生电网上存在浪涌电压（例如雷击或断开电感性负载时容易在电网上产生浪涌）时压敏电阻就会将这部份能量消耗掉。

甚至会由于通过压敏电阻的大电流将熔断器烧断而切断电源。
