| 摘要 |
The invention relates to a measurement system (MS) for compressor (TC) performance monitoring and to a respective measurement method. To most efficiently evaluate the operational performance the invention proposes said measurement system (MS) comprising at least four boxed units (BU) wherein a first boxed unit (BU1) is connected to or comprises sensors (MFS) to directly or indirectly measure a mass flow (MF) or volume flow (VF) being compressed by the compressor (TC), wherein a second boxed unit (BU2) is connected to or comprises sensors (CS) to directly or indirectly measure
a) a compressor inlet temperature (TCI),
b) a compressor outlet temperature (TCO),
c) a compressor inlet pressure (PCI),
d) a compressor outlet pressure (PCO),
wherein a third boxed unit (BU3) is connected to or comprises sensors (PS) to directly or indirectly measure
a) current (CP) of the power supplied to a drive motor (DM) of said compressor (TC),
b) voltage (VP) of the power supplied to the drive motor (DM),
wherein a fourth boxed unit (BU4) is signal transmitting connected by a connection (C1 - C4) to said boxed units (BU1 - BU3) and comprises a storage (SDC) to store collected measurement data from said boxed units (BU1 - BU3) into said storage (SDC). Further a measurement method is proposed. |
