- Control Of Positive-Displacement Air Blowers (AREA)
Description
・温度上昇率ΔTがBよりも小さい場合には、冷却器が劣化していると判断する。
・温度上昇率ΔTがBよりも大きい場合には、一度無負荷運転へと移行する。
・無負荷運転移行後、温度TがCよりも大きい場合には断水(冷媒不足)と判断する。
・無負荷運転移行後、温度TがCよりも小さい場合にはサージングが発生したと判断する。
Claims (1)
- 複数の圧縮段と、この複数の圧縮段間に配置され前段で圧縮されたガスを冷却する中間冷却器と、吸込み流量を調節する吸込弁と、圧縮機の吐出側に設けられ圧縮空気を放風する放風弁とを備え、前記吸込弁を閉じ前記放風弁を全開にして無負荷運転するターボ圧縮機において、
前記中間冷却器を通過し次段圧縮機に流入するガスの温度を検出する温度検出装置と、この温度検出装置が検出した温度の時間変化から温度上昇率ΔTを演算しこの圧縮機を制御する制御装置とを設け、この制御装置は、前記温度検出装置が検出した温度が、通常の運転時の温度よりも高く定めた温度規定値Cよりも高いときに、断水時の温度上昇率ΔT2よりも小さく冷却器劣化時の温度上昇率ΔT3よりも大きいものとして予め定めた温度規定値Bと温度上昇率ΔTとを比較し、温度上昇率ΔTが規定値Bよりも大きいときは、圧縮機を無負荷運転させ、その後前記温度検出装置が検出した温度Tが規定値Cよりも大きいときには断水と判断し、規定値Cよりも小さいときにはサージングと判断することを特徴とするターボ圧縮機。
