Due to its nature, the oil monitoring of subway lubricating oil needs to consider the following aspects when establishing an oil monitoring laboratory or selecting oil monitoring equipment:
1. Quickly and conveniently achieve the detection purpose.
2. The sample usage is low.
3All key oil monitoring indicators must be covered, including pollution, aging, and wear as a whole.
4Intelligent diagnosis. The test results can directly provide diagnostic opinions, transform the test report into effective decisions, and reduce reliance on personnel.
5. The test results must be quantified, and qualitative testing equipment that heavily relies on the experience of analysts or equipment that requires secondary development should not be selected. The equipment must be able to be used directly and produce test results directly.
6The equipment is sturdy and durable, but due to the complexity of the oil samples used and the lack of corresponding experience among the users, the equipment cannot be spoiled.

Based on the above requirements, the Minilab153 industrial field oil monitoring system and portable iron meter from Speechao Technology are suitable for the above requirements and mainly consist of several devices:

1. SpectrOil 120C: Oil Spectral Analyzer--Quickly locate the location, degree, and trend of wear;

2. LNF-220: Multi functional abrasive particle analyzer-Oil contamination detectionIntelligent ferrography detection (wear traceability analysis)

3. FluidScan-Q1000: Portable Oil Condition Monitor-Moisture content, acid value, oxidation degree

4. MiniVisc-Q3000: Portable Kinematic Viscometer-Kinematic viscosity @ 40 ℃ (actual test result)

5. TruVu Intelligent Oil Monitoring Platform-TruVu 360TM server software system - a software platform based on network technology;

6、FErrCheck2100: Portable Iron Gauge-Detection of concentration of ferromagnetic particles.
