How to check the vibration zone of Dalianhuanyou shielded pump and ask for help
Thread Content
How do you see it in the picture? It vibrates.
Dalian Empire's, the green color is normal, the red bearing is more worn.

When the bearing is working normally, the rotor rotates at the center of the stator, and the fundamental waves of the two windings are the same in size but in opposite directions, so the signal output from the junction box to the monitoring instrument is only the difference between the two harmonics, and the pointer is in the green zone ； 2. When the bearing wear increases, the sum of the harmonics and the fundamental difference between the two coils increases significantly, and the pointer is located in the yellow area, reminding personnel to pay attention to the need to replace the bearing! 3. If the pointer is in the red area, operation is strictly prohibited! Otherwise, the bearing may be seriously worn and the stator may come into contact with the rotor, causing the stator shielding sleeve to wear and cause damage to the motor. Since the rotation of the shaft cannot be seen from the outside of the canned pump, it can only be judged by the TRG meter, pump outlet pressure, and flow rate. For example, when the pump is started and the TRG meter indicates red, the outlet pressure is low, and the adjustment is ineffective, it can basically be judged that the pump is reversed.
I didn’t see any pointers :lol
Directly consult the large chain friend manufacturers!
TMG meter, an alternative to TRG meter, can reduce electromagnetic influence
Very professional interpretation* Got it
I have to take off the plastic cover to take pictures. I have a lot of Dalian canned pumps, they are easy to use.
We have someone who has been in Taihuang District for a year.
