● 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。

序号1、2规格的压力控制器

序号3~11规格的压力控制器

● 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。

● 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。
