Does the vibration increase after replacing the motor of the equipment? It's possible that there was a problem with the alignment
Date: 2022-03-10Read: 16
The hammer crusher is a high-speed equipment, generally using two-stage and four stage motor direct transmission. However, users often report that the vibration of the crusher has increased after reinstalling the motor. What is going on with the mold water flushing machine?
In fact, due to the high speed of 2900 revolutions per minute (RPM) of the crusher, if the motor deviates from the center of the spindle, it will cause vibration. If it runs for a long time, it will cause abnormal wear of the motor and bearings.
All crushers of Spring Valley Company are installed using SKF laser alignment technology:
1、 Testing tools and instructions for use:
SKF laser alignment instrument
2、 Test location:
The installation position of the sensor and the initial data setting position are shown in the figure:
Instructions:
1. Distance A is the distance from the S-end sensor to the M-end sensor
2. Distance B is the distance from the M-end sensor to the motor * bottom corner bolts
3. Distance C is the distance between the two bottom corner bolts of the motor
3、 Testing method
1. Install sensors:
As shown in the figure, install the S sensor and M sensor on the motor shaft and spindle, with the S sensor installed on the spindle end and the M sensor installed on the motor shaft end. After initial positioning with the chain, use the knob to lock it in place. Observe the horizontal block and adjust the sensor direction slightly until it reaches the horizontal position before locking the knob.
Use the sensor height adjustment knob to preliminarily adjust the sensor height so that the two sensors are at the same height.
Insert the sensor into the controller (with the infrared light on), use the infrared high-low adjustment switch to calibrate both sensors, aligning the infrared light emitted by the S sensor with the infrared signal calibration line of the M sensor, and aligning the infrared light emitted by the M sensor with the infrared signal calibration line of the S sensor.
2. Measurement of basic data and equipment initialization:
Use a tape measure with a level to measure three data points A, B, and C (see measurement location for details) and set them from the controller.
According to the prompts on the controller, adjust the sensor to the 9 o'clock and 3 o'clock positions, and set the initial position from the controller
3. Calibration alignment
Adjust the sensor to the 12 o'clock position and calibrate the vertical alignment.
Adjust the sensor to the 3-point position to calibrate the horizontal alignment.
