各位大哥！小兄弟有一事相求大家给我指导；65机第三区温度在升温保温过程中很正常，设定温度为92度。一开机温度上升道100度左右，无法下降。并且显示冷却阀一直打开着。即使强行打开冷却阀循环冷却，仍然是温度无法下降。温度设定及显示是触摸屏的，采样和执行是西门子S7-300  SM331(AI8xTC)K型分度号热电偶、  SM322(DO32x24VDC)24VDC通用小型继电器接通220V冷却电磁阀线圈电源。希望能得到大哥指点。

现在发现65机转速越快温度越高大概升至110度左右，降速时温度降得很快降至45度左右。大哥们帮帮忙，给我多多的分析一下。我先谢谢你们！！！

<DIV class=xxxxContent id=deds6 style="OVERFLOW: auto; WIDTH: 100%">现在我发现温度上升的原因是机堂与螺杆摩擦引起的，但是就是冷却不下来。该怎么办大哥些？专家些？<IMG src="http://www.dxdlw.com/images/Emotions/1.gif" onload="javascript:if(this.width>800)this.width=800;if(this.height>600)this.height=600;"></DIV>

  正常现象，以为主机运转产生热量，加上最近天气本身就很热。光靠冷却风扇是不行的 。

 要想更好的减温效果，可以采用水冷却炮筒，这样更快，或者安装更好的风冷却系统。

查看冷却系统是否正常及有效

谢谢你们！winter321、线线缆缆。水冷却系统没有问题，在65机转速下降时，温度下降很快。在20分钟时间内，100度左右降至50度左右。然后温度才开始慢慢上升。

另外我个人认为冷却铜管和机堂外面接触面有无关系？

如果是水冷的话，建议看看阀芯是否能够自由关闭
qiuyiren --- 2011-08-22 10:01:12

taoyuan 谢谢你！我检测冷却电磁阀水流量、压力、阀芯关闭很正常。
winter321 --- 2011-08-24 12:23:48

检查一下蜂巢板及滤网是否过密？
JSCZDXY --- 2011-10-10 16:04:57

看看热电偶接触是否良好；冷却水是否通畅。

找维修的把
