NSK bearing temperature rises slowly; generally. 1-2 hours; to reach stability. NSK bearing normal temperature due to mechanical; often high temperature; if necessary, suspend operations; adopt necessary avoidance measures. Based on many test data; Lists the various mechanical operations; the average temperature of the outer ring of the bearing; for reference. After smoothing; because of temperature; speed; load; environment; the values ​​in the table indicate approximate temperature scale. Temperature sensor; can be monitored at any time Bearing operating temperature; temperature exceeds the specified value; and complete the alarm user or active suspension; avoid burning the shaft event.
1. The first is to identify and view the size and sound quality of the nsk bearing tumbling sound according to the nsk bearing tumbling sound. Because the nsk bearing has slight damage such as peeling; the sound detector can be selected. Tone and irregular sounds; therefore, the sounder can be used for resolution; it can be avoided early.
2. Secondly, the nsk bearing is oscillated in the operation to identify and view; nsk bearing oscillation is very sensitive to the damage of the bearing, such as shedding, indentation, rust, crack, wear, etc., which will be reflected in the oscillation measurement of the nsk bearing. The nsk bearing oscillating measuring device (frequency analyzer, etc.) can measure the large oscillation. ü De Shi Zhi 豢 豢 鲆 鲆 鲆 5 5 5 5 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭 咛迩榭Not the same; therefore, the need to analyze and compare the measured values ​​of each machine beforehand to determine the criterion.
3. Finally, according to the temperature of the nsk bearing, the temperature can be estimated based on the outdoor surface of the nsk bearing. If the oil hole can be used to directly measure the bearing outer ring temperature; the temperature of the nsk bearing is more suitable. The NSK bearing temperature rises slowly. Operation; general. 1-2 hours; to reach a stable condition. The normal temperature of NSK bearings is different due to mechanical; heat; speed and load heat capacity. If it is smooth; suitable equipment; the temperature of the bearing will be agile; There will be abnormally high temperatures; if necessary, the operation will be suspended; the necessary avoidance measures will be adopted. Based on many test data; Table 4-1 lists the various mechanical operations; the average temperature of the outer ring of the bearing; After smoothing; because temperature; speed; load; environment; the values ​​in the table indicate the approximate temperature scale. Temperature sensor; can monitor the operating temperature of the bearing at any time; the temperature exceeds the specified value; and complete the alarm user or active suspension; avoid burning the shaft Thing.

LED Tube Lights

LED tube lights are becoming increasingly popular due to their energy-saving benefits, eco-friendliness, and aesthetic appeal. LED tubes, also commonly known as LED tubelights or smart tube lights, are an innovative alternative to traditional fluorescent tube lights. These advanced lighting solutions offer a brighter and more reliable lighting source than other types of bulbs. With the advancements in technology, LED tube bulbs have become the preferred lighting solution for most commercial and residential buildings.
