压力控制器是工业过程测量与控制系统中控制压力的一种仪表,工程中通常称作压力开关。根据工作原理分为以下两大类。
根据工作原理分为以下两大类:
1、机械式压力控制器 ;
2、电子式压力控制器。
机械式压力控制器是机械形变导致微动开关动作,在制冷系统中主要用作高低压压力控制器。
工作原理:
当系统内压力高于某一个设定压力计时,不同的压感元件(弹簧管、膜片、膜盒、波纹管、活塞等)的自由端产生位移,通过链接导杆推动开关内碟片瞬时发生移动;当压力降至额定的恢复值时,碟片瞬时反向移动,开关自动复位,*终输出一个开关量的电信号。
术语和定义:
压力控制器 pressure switch:当输入压力达到设定值时,通过输出触头的通断作用起到对被控压力的控制和报警作用的仪表。
控压范围 range:控制器能够控制的压力范围。
设定点(值)set point:希望发生控制或报警的输入压力值。
切换值 switching value:位式控制仪表上行程(或下行程)中,输出从一种状态换到另一种状态时所测得的输入值。
上切换值 high-switching value:输入压力上升时,使控制器产生控制或报警信号发生变化时的压力值。
下切换值 low-switching value:输入压力下降时,使控制器产生控制或报警信号发生变化时的压力值。
切换差 differential gap:同一设定点上切换值和下切换值之差。
设定点偏差 set point error:输出变量按规定的要求输出时,设定值与测得的实际值之差。
设定点(值)范围 set point range:设定点可调的控制器,设定点可以调节的*压力值与*小压力值之差。
