Analysis of the morphology and composition of sliding the NSK bearings wear residue number of granularity. Magnetic plug inspection method applies to the residue particle size greater than the case. Other methods such as the membrane assay infrared spectroscopy the jurisprudence of performance Prosecution, particle counting method. These methods are not applicable to online testing. The heat in the bearing oil temperature detecting method is mainly by the friction loss of the function of changing from a predetermined average temperature not exceeding the type of oil temperature detection method.
Thermocouple thermometry is a, radiation thermometry thermometer the lower limit temperature it is not used for sliding bearing oil temperature detecting infrared photography method is a non-contact method of one of the most commonly used method of resistance thermometry are also common the online monitoring bearing temperature of the oil with the optical system of the bearing of the infrared heat radiation set naphthalene to the infrared detection element to the infrared radiation is converted into a weak electrical pulse signal at this signal through the electronic circuit to enlarge.
