Stainless steel high temperature bearing cleaning misconduct caused severe burns how can solve a: quality standard experiment.
According to jb/t20.
50 -
2005 the provisions of the state, the high temperature stainless steel bearing the impurities into the cleaning fluid, after filtration, drying, weighing, calculate the quality of the impurity particles in the cleaning fluid.
II: the experimental microscope.
The method of previous research procedure and quality standard for similar, different cleaning fluid is filtered, direct microscope can be observed in the membrane filter impurities particle size and number.
And we also can provide basis for the appearance of these impurities, identify the chemical composition and content of impurities.
This method is suitable for fine high temperature heat SKF bearing structure leads to the determination of bearing cleanliness.
III: experimental automatic particle counting method.
Automatic control particle calculation method and quality standard, microscope method is different, it is the enterprise application research on the photoelectric technology principle theory, directly on the impurity particles quantity and size can be concluded that way.
This way can't compare with high precision, the ordinary method suitable for cleanliness request a higher high temperature stainless steel bearing.
High temperature high temperature bearing according to burn the so-called SKF bearing burn status refers to: the high temperature of the wheel and the roller bearing raceway in rotation and attached frame rapid heating until the discoloration, softening and melting and damage.
The main reason for the high temperature bearing burn is due to the high temperature stainless steel bearing finish is poor, lubricant use undeserved, or lubricant too much, too little, is not correct.
May be too much load (
Preloading is too big)
。
Speed is too large.
The gap is too small.
Water or other foreign material.
Without the above two conditions, making the shaft, high precision, large deflection axis bearing is bad.
See here, I want to handle it, everyone wants to know first, discuss the smooth agent, smooth, high temperature stainless steel bearing smooth election agent, its quantity method, and the selection of the correct SKF bearing temperature.
Discussion in order to adapt to high temperature bearing clearance and preload, and improving the seal installation.
Check the accuracy of the shaft and bearing shell temperature.
The previous: what is the bearing with grease what's important role in the next article: no
