Definitions

  • the invention relates to a measurement system and a measurement method for compressor performance monitoring.
  • the invention proposes a measurement system of the incipiently defined type with the additional features of the characterizing portion of claim 1. Further the invention proposes a method according to the independent method claim.
  • the respectively dependent claims relate to preferred embodiments of the invention.
  • a boxed unit according to the wording of this document has the features which are normally connected with the term "black box”. Further the boxed unit has indeed an outer shell protecting the inside of the boxed unit from mechanical impact. Further the boxed unit can be connected in a signal transmitting way to other boxed units either by cable or wirelessly.
  • the boxed unit according to the invention has at least its own power supply or a power input to be connected by a plug-in cable to an external power supply. Preferably the boxed unit is sealed against the outside against dust and/or humidity and/or water.
  • boxed unit is the flexibility to arrange a measurement network by setting up several boxed units measuring mass flow or volume flow, pressure and temperature and current or voltage or both and connecting these three types of boxed units to at least one forth boxed unit receiving the measurement results by the signal transmitting connection by wire or in a wireless way.
  • several of the three types of boxed units can be connected to one forth boxed unit receiving all the measurement results.
  • several compressors can be measured with regard to the electrical power consumption by monitoring the current and voltage received by these compressors by several respective third boxed units, wherein all these third boxed units transmit these measurement results to only one single forth boxed unit.
  • this forth boxed unit is connected to the other boxed units by a wireless signal transmitting connection.
  • One preferred embodiment of the invention provides a measurement system according to the invention, wherein said forth boxed unit comprises a data acquisition device, wherein data acquisition is the process of sampling signals that measure real world physical conditions and converting the resulting samples into digital numeric values.
  • At least one of the first, second or third boxed unit comprises a data acquisition device converting the measured analog signals into digital numeric values.
  • Most preferred all boxed units, namely the first, second or third boxed unit, measuring real world physical parameters comprise a data acquisition device converting these parameters into digital numeric values.
  • These digital numbers are suitable to be transferred by a wireless local area network (LAN) connection from at least one of the first, second or third boxed unit to the forth boxed unit receiving digital values as measurement results.
  • LAN local area network
  • said storage to the forth boxed unit as a flash EEPROM especially made as a SD card (secure digital memory card).
  • Another preferred embodiment provides said forth boxed unit comprising a general package radio service modem (GPRS).
  • GPRS general package radio service modem
  • each boxed unit is part of that network and is a suitable equipped to be a wireless LAN station.
  • the forth boxed unit is a wireless access point, being a wireless router and working as a base station for at least one of a first boxed unit, a second boxed unit and/or the third boxed unit.
  • a field comprising several compressors several first boxed units, second boxed units and third boxed units might be connected to the forth boxed unit being the wireless access point.
  • a compressor field comprising several compressors wherein one selected compressor is a reference compressor being equipped with a first boxed unit, a second boxed unit and a third boxed unit and the other compressors are only equipped with a third boxed unit, wherein all these boxed units are connected to one forth boxed unit preferably wirelessly, wherein said forth boxed unit is the wireless access point and the other boxed units are clients.
  • the forth boxed unit comprising a USB-interface enabling data transmitting connection to other USB-interface devices. It is further preferred that said forth boxed unit can be connected in a wireless way to other computer-like devices like mobile phones, laptops or similar equipment. These devices may be beneficially used to visualize the operating parameters of the compressor plant to give the operator a quick possibility to observe the condition of the plant.
  • Figure 1 shows schematically a single compressor setup comprising the measurement system according to the invention and being monitored by the method according to the invention.
  • a turbo compressor TC is driven by an electric drive DR being connected by a coupling CP to a gear GR transferring the speed of the drive DR to at least one impeller of said turbo compressor TC.
  • This setup is mounted to a platform PT and fixed to the ground by said platform PT.
  • the electric drive DR is supplied with electrical power by a power supply PS by means of three phase electricity, wherein said motor drive DR is a variable speed drive and said power supply PS is designed such that a variable frequency output enables speed control of said drive DR.
  • Said turbo compressor TC sucks a process fluid respectively ambient air through a filter FL and delivers said process fluid PF into a pressure line PL.
  • the fist boxed unit BU1 comprising a data acquisition device DAQ is connected by a first signal line BU1L to a flow meter placed in pressure line PL.
  • Said flow meter MFS measures the volume flow VF or the mass flow MF.
  • a second boxed unit BU2 comprises a data acquisition device DAQ and is connected by second signal lines BU2L respectively to sensors in the compressor inlet and the compressor outlet.
  • the sensors in the compressor inlet are an inlet temperature sensor PTCI and an inlet pressure sensor PPCI.
  • the sensors in the outlet are an outlet temperature sensor PTCO and an outlet pressure sensor PPCO.
  • the measured data is received by the second boxed unit BU2 and converted by said data acquisition device DAQ from analog data into digital data.
  • a third boxed unit BU3 comprising a data acquisition device DAQ is connected to sensors located in the power supply line PSL between the power supply PS and the electric drive DR.
  • a current sensor PCP and a voltage sensor PVP measure the power transmitted through the three phase power supply line PSL from the power supply PS to the electric drive DR.
  • This analog information is transmitted by a third signal line BU3L to the data acquisition device DAQ of the third boxed unit which transforms the analog data into digital data.
  • the first boxed unit BU1, the second boxed unit BU2 and the third boxed unit BU3 are connected respectively preferably wirelessly by a first connection C1, a second connection C2 and a third connection C3 to the forth boxed unit BU4 collecting the digital data resulting from the measurement installing this data in a storage SDC.
  • the forth boxed unit comprises a USB-interface to be connected to other USB compatible devices.
  • a GPRS-modem of the forth boxed unit enables wireless access to the storage of the forth boxed unit.
  • FIG. 2 shows a compressor plant being monitored according to the method of the invention by a measurement system according to the invention.
  • the compressor plant comprises a first compressor TC1, a second compressor TC2, a third compressor TC3 and a forth compressor TC4.
  • the first compressor TC1 is a reference compressor being equipped with a first boxed unit BU1, a second boxed unit BU2 and a third boxed unit BU3.
  • the remaining compressors TC2, TC3, TC4 are equipped with a third boxed unit BU3 only monitoring the power consumption. All these boxed units BU1, BU2, BU3 are connected wirelessly to one single forth boxed unit BU4 collecting all the data and storing this data in said storage SDC.
