VENT RECOVERY COMPRESSOR K-5214 DISCHARGE PRESSURE
CONTROLLER (CONTROL LOOP DIAGRAM SHEET 15)排放气压缩机 K-5214 出口压力控制器 (控制回路图 15)
The vent recovery compressor discharge pressure is controlled by using two control room mounted pressure controllers (PIC-5214-3A and PIC-5214-3B) and two pressure valves (PV-5214-3A and PV-5214-3B). PIC-5214-3A/PV-5214-3A controls the discharge pressure and limits the pressure swings through the refrigeration system. PIC-5214-3B/PV-5214-3B controls the discharge pressure by sending flow back to the vent recovery surge tank whenever the pressure exceeds the setpoint.
排放气压缩机的出口压力通过使用控制室安装的压力控制器(PIC-5214-3A和PIC-5214-3B)以及两个压力阀(PV-5214-3A 和 PV-5214-3B)来控制。PIC-5214-3B/PV-5214-3B 控制出口压力并限定去冷凝系统的压力波动。无论何时压力超过了设定值，PIC-5214-3B/PV-5214-3B 通过将流量返回到排放气回收缓冲罐来控制出口压力。
PIC-5214-3B shall be tuned with a “fast” response time as compared to PIC-5214-3A. This will allow the compressor discharge pressure to be gradually controlled using PIC-5214-3A by controlling the flow to C-5204. PIC-5214-3B quickly reduces the discharge pressure via popback to the compressor suction if PIC-5214-3A discharge control is insufficient. PV-5214-3B can also be controlled by the high select between PIC-5214-3B and PIC-5236-4. PIC-5214-3A and PIC-5214-3B share the same pressure transmitter. PIC-5214-3B has a higher set-point than PIC-5214-3A. HS-5214-3B is a high signal selector, The signals from PIC-5236-4 and PIC-5214-3B input to this selection. The higher signal from HS-5214-3B will control the valve PV-5214-3B.
PIC-5214-3B 与PIC-5214-3A.相比较应调整有“fast”的反映时间。这将允许压缩机使用PIC-5214-3A 通过控制去C-5204的流量来逐渐的控制出口压力。如果PIC-5214-3A 的出口控制不满足的话，PIC-5214-3B 将通过返回压缩机入口来快速的降低出口压力。PV-5214-3B也能通过在PIC-5214-3B 和PIC-5236-4之间的高选择来控制。PIC-5214-3A 和PIC-5214-3B 共同使用一个压力变送器。PIC-5214-3B的设定值高过 PIC-5214-3A。HS-5214-3B是一个高信号选择器，来自PIC-5236-4 和 PIC-5214-3B的信号输入到这个选择中。来自HS-5214-3B的较高信号将控制阀PV-5214-3B。
