I. Product Introduction

The main ways of mechanical equipment failure are wear, corrosion and fracture. Among them, wear failure accounts for as much as 60%-80% of the impact on mechanical equipment failure. Lubricating oil is the blood of mechanical equipment, and plays the role of sealing, lubrication, cleaning, cooling and corrosion prevention in mechanical equipment. Lubricating oil contains mechanical wear information, that is, the friction and wear characteristics of the friction pair surface material. By monitoring the lubricating oil, it can detect the contamination of the lubricating oil itself and analyze the wear state of the machine. The concentration of ferromagnetic particles in the lubricating oil is one of the direct indicators of the degree of wear of the controlled equipment. By performing daily ferromagnetic particle concentration analysis on the oil in use, the abnormal degree of wear of the equipment can be quickly identified to avoid unplanned downtime.

In terms of detection methods, the current iron content detection mainly includes atomic absorption method and atomic emission method. Although the atomic absorption spectrometry method is accurate, it is slow and complicated to operate. The atomic emission spectrometry method has been widely used, but it cannot effectively detect large wear particles (whether it is a rotating disk electrode or an inductive ion coupling method). It is not sensitive to large particles, which is sometimes fatal in monitoring and diagnosis, because the particles of normal wear of friction pairs are generally less than 10μm, while metal particles greater than 15μm are produced by abnormal wear.

Portable ferromagnetic wear debris measuring instrument TTL-5 uses the electromagnetic induction principle to measure the wear debris content by using the magnetic field change of the sensor coil caused by the ferromagnetic wear debris in the oil sample. It has a good linear relationship with the iron content and particle size of the oil sample. It has high sensitivity, accuracy and repeatability. It does not require sample pretreatment or organic solvents. It can measure the accurate content of ferromagnetic metal abrasive particles in various oil samples within a few seconds. The measurement results are directly expressed in actual concentration values (mg/L or ppm), which facilitates the user's interpretation and analysis of the data. It is widely used in defense, aerospace, shipbuilding, electric power, petrochemical, metallurgy, mining, road transportation and other fields.
