Embodiment

[0089] The present embodiment provides a kind of application situation of gas compressor state parameter monitoring system and method, by gas pressure sensor 1, detection pressure signal is passed to signal conditioner 3, passes to PXI data acquisition card (7) after signal processing, And transmit it to the computer, through the LabVIEW software platform, read the pressure of the primary exhaust valve as 0.63 MPa, compare it with the set upper limit of 0.62 MPa, judge that the exhaust pressure is higher than the normal exhaust pressure, and find the status of the gas compressor The parameter abnormality and fault correspondence table establishes that the main potential fault modes include damage to the exhaust valve, damage to the suction valve, excessive gap between the piston ring and the cylinder, and pressure gauge failure. diagnostic module;

Abstract

The invention discloses a state analysis monitoring system of a gas compressor. The state analysis monitoring system comprises a gas pressure sensor, a temperature sensor, a signal conditioner, an engine oil pressure sensor, a vibration sensor, a vibration meter, a data collection card, a display and a computer. The invention further discloses a state analysis monitoring method of the gas compressor. In the state analysis monitoring method, a gas pressure signal, a temperature signal, an engine oil pressure signal and a vibration signal are input into the computer and are processed through the following steps of: comparing the signals with the upper limits and the lower limits of preset safe values, if the upper limits or the lower limits are exceeded, alarming and starting a failure diagnosis module at the same time; querying a gas compressor state parameter exception and failure mapping table in a failure diagnosis module to determine a corresponding exceptional component type; querying the historical maintenance record of each component in the exceptional component type in a database; calculating service life values of different components corresponding to the exceptional stateparameters; and checking from the component with a minimum service life value to the component with a maximum service life value in sequence until the fault component is found out, thereby finishing the state analysis monitoring.

Description

technical field [0001] The invention relates to the field of monitoring and analysis of electromechanical equipment, and in particular provides a state analysis and monitoring system and method of a gas compressor. Background technique [0002] Gas compressors play an important role in chemical production processes involving the need for pressurization of gaseous media. Monitoring the working condition of the compressor helps to detect potential failures and predict life in advance, so that measures can be taken as early as possible to reduce or avoid production losses. [0003] At present, most of the monitoring systems used in terms of safety, reliability, availability and economic benefits of the gas compressor system are industrial computers. Using reliability analysis techniques. Some monitoring systems fail to make full use of status monitoring signals even if they use system reliability analysis technology, resulting in failure to monitor equipment well, analyze its...
