产品介绍

一、产品描述


   YK系列压力控制器是一种自动控制和保护装置,它系随着压力的变化而使电路闭合或断开的电开关,用于船舶、冷冻设备及其他工业设备与执行机构配套,对气体、蒸汽或液体的压力进行两位式控制。

二、工作原理


  当被控制系统的压力上升或下降时,控制器的相应调节弹簧和波纹管产生伸长或收缩的移位,通过杠杆推动开关动作,切断或接通控制器,从而达到对介质压力两位式控制目的。


三、安装须知


1、本系列压力控制器有二种安装形式:

   a) 用安装板过渡安装:此方法安装时应注意:被使用的4只M4安装螺钉的长度不应超过6毫米(此规格螺钉作为附件随机出厂)

   b) 用控制器本体直接安装:此方法安装时应注意,控制器壳体底部与安装面之间,每安装孔上须安放二只Φ6平垫圈。

2、控制器在安装连接管时应注意,绝对不能用一只扳手直接将接管螺母板紧,必须用二只扳手,分别在控制器气管接头与接管螺母二端同时扳紧,以保证控制器不致损坏,另外,连接铜管的扩口处应呈软态(退火)。

3、电气接线时,必须看清控制器的接线图示后方可接线,以免控制器工作失常。

*    示例:

如控制气体压缩机的输出压力保持在0.5-0.6Mpa之间。

1. 选用0-0.8Mpa规格的压力控制器。

2.把控制器的连接螺母拧出,将导管连接在被控气源上,然后用两只扳手将控制器与导管连接密封,将控制器的开关接线并接入压缩机的电源电路中。

3. 旋动压力调节螺杆,使指针指示在0.6Mpa处。旋动压差调节螺杆,使指针指示在0.1Mpa处。

4.接通电源,使压缩机工作,就能达到当气压上升至0.6Mpa时开关断开,当气压回落到0.5Mpa时开关接通的目的
