Monitoring of the working state of Conveyor idler
Clicks:9526 Date:12-23
1. requirements for monitoring Conveyor idler using a magnetic plug
(1) the magnetic plug is only suitable for monitoring the key main bearings that are lubricated by oil and are used to return oil through a special pipe.
(2) magnetic plug should be installed near the main bearing which is monitored, and it is on the main channel of oil return. There is no barrier screen, oil pump and other hydraulic parts in the middle.
(3) in order to improve the efficiency of monitoring, a rotary oil storage device with oil recovery and import and export can be made. The oil storage device should be made into an inverted conical form, and the magnetic plug is installed at the bottom of the oil receptacle. The inlet of the oil storage device should be inclined to a certain angle, so that the lubricating oil can be entered into it from the tangential direction. This helps to separate the wear particles from the rotary lubricating oil, and precipitates at the bottom, enters the magnetic plug through a small hole, and adsorb on the end of the magnetic steel.
Morphological characteristics of wear abrasive grains under 2. normal conditions
In the running and normal running period of Conveyor idler, the size of the debris debris is generally 0.01 ~ 0.015mm, and some metal powders are mixed. The number of debris produced by the new bearing during running in period is more than that in normal running period. After entering normal running period, the number of debris and metal powder will decrease significantly. The debris has a thin and short shape under the microscope, with irregular sections.
The morphological characteristics of 3. malfunction wear abrasive particles
The main failure form of Conveyor idler is fatigue pitting. The size of the debris debris formed by rolling fatigue and exfoliation is generally 0.025 ~ 0.05mm. Sometimes there are bigger pieces and some metal powder. The ball of the ball bearing abrasive debris usually appears almost round, divided radially rose petals form; abrasive debris raceway showed roughly circular surface broken forms; roller bearing roller of abrasive debris usually exhibit a length equal to 2 ~ 3 times the width of curved rectangular form; abrasive debris roll the generally rectangular irregular.
