PT300SAT Balancing Alignment Simulator

The PT300-SAT shaft alignment and dynamic balance simulation test bench is specifically designed for in-depth research on bearing faults, misalignment, and unbalance issues in mechanical faults, which account for over 90% of mechanical faults. During the initial design of the test bench, full consideration was given to minimizing additional changes in external conditions when replacing components. This allows for the acquisition of useful data under the same working conditions, ensuring the accuracy and consistency of analysis results.

• Practice of vibration measurement and selection of vibration sensor positions;

• Impact of rotor unbalance on vibration;

• Impact of shaft misalignment on vibration;

• Simulation of soft foot faults;

• Simulation of belt faults;

• Simulation of bearing faults (bearing inner ring fault, bearing outer ring fault, bearing cage fault, bearing rolling element fault, and comprehensive bearing fault);

• Simulation of single-plane and double-plane dynamic balance.

• Diameter d1 = 140 mm, with 36 M5 holes at 10° intervals;

• Diameter d2 = 130 mm, with 36 M5 holes at 10° intervals;

• Diameter d3 = 120 mm, with 18 M5 holes at 20° intervals.

• Diameter d1 = 136 mm, with 15 M5 holes at 24° intervals;

• Diameter d2 = 65 mm, with 5 M6 holes at 72° intervals.

• Adjustment knobs: for fine-tuning the centering state;

• Dial indicator: for accurately measuring and indicating the amount of misalignment.

1. Four-way movement: The motor base can move in four directions to flexibly create misalignment;

2. Dial indicator indication: Accurately measures the amount of misalignment to ensure operational accuracy;

3. Real-time analysis: Observes changes in vibration signal patterns in real-time for easy comparison and analysis;

4. Centering restoration: Can be accurately restored to the original centering state after testing to ensure equipment stability.

• Front left foot: shortened by 0.6 mm;

• Front right foot: shortened by 0.2 mm;

• Rear left foot: shortened by 0.4 mm;

• Rear right foot: shortened by 0.4 mm.

1. The front left foot is 0.4 mm shorter than the right foot: This design intentionally creates a soft foot phenomenon, which users must correct before performing centering work, thereby learning how to detect and correct soft feet;

2. Gaskets and spring bolts: Used to adjust and fix the base feet to ensure centering accuracy;

3. Motor base design: The motor base provides sufficient operating space for centering work, and the feet are equipped with independent centering base mechanisms;

4. Dial indicator and adjustment knobs: A dial indicator and left-right knobs are installed to guide the amount of centering movement, ensuring adjustment accuracy.

• By simulating misalignment conditions in actual industrial scenarios, it helps users master centering techniques and fault diagnosis methods;

• Provides convenient operating space and adjustment mechanisms to make centering work more efficient and accurate.

• Leftmost: Inner ring faulty bearing;

• Second from the left: Outer ring faulty bearing;

• Rightmost: Cage faulty bearing;

• Second from the right: Rolling element faulty bearing.

1. Loosen the screws on the bolts of the central bearing block, push the bearing to be tested in and fix it;

2. Measure after installing the acceleration sensor.

• This design minimizes changes in boundary conditions, enabling immediate and accurate comparison between normal and faulty states, and avoids the process of completely disassembling and reassembling the rotor assembly to replace bearings.

1. Inner ring faulty bearing (0.55mm);

2. Outer ring faulty bearing (0.55mm);

4. Cage faulty bearing.

1. Inner ring faulty bearing

• Identification: Marked with "I" in English on the bearing ring;

• Fault characteristic: A 0.55 mm crack on the inner ring;

• Fault frequency: 5.427 X.

2. Outer ring faulty bearing

• Identification: Marked with "O" in English on the bearing ring;

• Fault characteristic: A 0.55 mm crack on the outer ring;

• Fault frequency: 3.572 X.

3. Cage faulty bearing (FBT-25)

• Identification: Marked with "T" in English on the bearing ring;

• Fault characteristic: The cage frequency (or fundamental rotation frequency) is the rotation speed of the rolling element cage assembly. This bearing simulates low-frequency modulated vibration phenomena by artificially creating faults on the cage;

• Fault frequency: 0.397 X.

4. Bearing rolling element fault (FBB-25)

• Ball faulty bearing, marked with the letter "B" on the bearing ring, with a 3mm spalling pit on the ball;

• Fault characteristic frequency: 2x fault characteristic frequency: 4.644 X.

• This component is used to simulate and analyze the vibration characteristics of bearings under different fault conditions, helping users learn fault diagnosis techniques;

• Each faulty bearing has clear identification and characteristic frequencies, facilitating users to conduct accurate fault analysis and comparison.
