一、离心式制冷压缩机蒸发压力过低

原因:(1)冷水量不足;(2)冷负荷少;(3)节流孔板故障(仅使蒸发压力低);(4)蒸发器的传热管因水垢等污染而使传热恶化(仅使蒸发压力过低);(5)冷媒量不足(仅使蒸发压力过低)。


处理办法: 排列5大小遗漏(1)检查冷水回路,使冷水量达到额定水量; (2)检查自动起停装置的整定温度;(3)检查膨胀节流管是否畅通;(4)清扫传热管;(5)补充冷媒至所需量。(一般蒸发压力在4.1-5.5之间 相应温度在1-8°C)


二、离心式制冷压缩机冷凝压力过高

原因: (1)冷水量不足;(2)冷却塔的能力降低;(3)冷水温度太高,制冷能力太大,使冷凝器负荷加大;(4)有空气存在;(5)冷凝器管子因水垢等污染,传热恶化。(一般冷凝压力在6.9-14.5之间 相应温度范围15-41°C


处理方法: (1)检查冷却水回路,调整至额定流量;(2)检查冷却塔;(3)检查膨胀节流管等,使冷水温度尽快接近额定温度;(4)进行抽 气  运转排除空气,若抽气装置需频繁运行,则必须找出空气漏入的部位消除之;(5)清扫管子。


三、离心式制冷压缩机油压差过低

原因:排列5大小遗漏 (1)油过滤器堵塞;(2)油压调节阀(泄油阀)开度过大;(3)油泵的输出油量减少;(4)轴承磨损;(5)油压表(或传感器)失灵;(6)润滑油中混入的制冷剂过多(由于启动时油起泡而使油压过低)。


处理方法: (1)更换油过滤器滤芯;(2)关小油压调节阀使油压升至额定油压;(3)解体检查;(4)解体后更换轴承;(5)检查油压表,重新标定压力传感器,必要 时更换;(6)制冷机停车后务必将油加热器投入,保持给定油温(确认油加热器有无断线,油加热器温度控制的整定值是否正确)。


四、离心式制冷压缩机油温过高

原因: (1)油冷却器冷却能力降低;(2)因冷媒过滤器滤网堵塞而使油冷却器冷却用冷媒的供给量不足;(3)轴承磨损。


处理方法: (1)调整油温调节阀;(2)清扫冷媒过滤器滤网;(3)解体后修理或更换轴承。(压缩机关机时,油温应高于60°C运行时高于4°C排列5大小遗漏 油压应在1.03-2.07之间)

八、电压过高或过低故障,实际运行电流与显示值不一致

电压信号由一个AC24V可调变压器供给,电压过高或过低报警时应检查电压采样信号是否在额定输入电压时为AC24V,否则应对变压器输出及控制中心显示值进行调校。


实际运行电流与显示值不一致时首先应使机组实际电流处于满负荷运行时,电流信号电压应约为AC0.5V,否则应调信号电阻值。显示值与实际运行值不一致时应在手动锁住导叶的情况下在显示板中进行调校(为保证安全运行可考虑显示值略大于实际值)。


九、机组常见泄漏点
