Mike Krzyzewski is really a famous coach of Dream Team. She has coached north america men's basketball team for some time, that's clinched numerous medals for his country. Following Londonfl jerseys supplyn Olympic was over, Krzyzewski told The Associated Press that this game will be his final one as national coach, a job he's held for seven years. He had left open the possibility of swomen nfl jerseystaying with the team beyond the London Games, when practice on Saturday said these will be his last Olympics.When asked if he was sure, Krzyzewski didn't hesitate before again saying, "yecheap nfl jerseys wholesales," this will be his last game "If we could win it, then it might be three major championships in a row, i always do not know when that has been done because we haven't usually won http://govoriotkrito.bg/libs/nflcn08.htmthe globe championships," Krzyzewski said. "It becomes an enormous thing for the program." Whatever, he's an awesome coach. His achievement are going to be remembered by the country.cheap nfl jerseys

◇ 设定值的调整:

    压力控制器的设定值调整步骤,举例说明如下:
    [例]:选用00.8MPa规格的压力控制器,要求控制气体压缩机的输出压力保持在0.50.6MPa之间,具体操作步骤如下:
     ● 将控制器的开关接线端子接入压缩机电机的电源控制回路中(接1.3端子则降压接通,升压断开)。将被控气体导入控制器波纹管室。
     ● 旋动设定值调节杆,使指针指示在标度尺刻度0.5MPa上,此值即为下切换值。
     ● 接通电源,使压缩机工作,气体压力上升。反复调整切换差旋钮,使压力上升到0.6MPa(上切换值)时控制器开关切换。

◇ 外形及安装尺寸:

序号1、2规格的压力控制器

序号3~11规格的压力控制器

◇ 安装:
     ● 打开表盖,将控制器垂直安装在仪表板上,严禁用手拨动或用工具碰撞拨臂,以防改变性能。
     ● 取下锁紧螺母旋动调节杆,使指针指在所需控制的压力设定值上,拧紧锁紧螺母。
     ● 旋动切换差旋钮,以获取需要的切换差。 
     ● 旋下接头将直径为6毫米的金属导压管的一断锡焊在套筒上,然后旋紧接头使连接管密封,
       被控介质由金属导压管进入波纹管室,如下图所示。

     ● 复查安装是否妥切,装好表盖,接通电源。根据控制器使用情况,应作定期校对。

单刀双掷微动开关作用过程:
接线端1-3:压力下降至下切换值时接通。
接线端1-2:压力下降至下切换值时端开。
电缆:φ12船用或φ7.5三芯。

◇ 注意事项:
     ● 控制器指针指示值为下切换值,设定值调节范围即下切换值调节范围。
     ● 切换差旋钮上数字仅表示切换差值的大小程度而非实际值,实际值应从标准表读取。
     ● 被控介质压力不超过某一给定压力值时,指针应调整在比给定值低一个切换差值(即下切换
       值)的位置上,调整完毕后,不准再旋动切换差旋钮。
     ● 规格表中给的切换差调节范围是指保证提供的最小调节范围,实际范围为可比表列略宽。
