Common faults and treatment methods of balancer

1.

Fault 1: the display value error is large.The display value error includes angle error and amplitude error.

Treatment: check whether the rotor is qualified;Whether the balancing speed is stable;the transmission of the sensor;re-calibration.

2.

 Failure 2: no rotating speed or display speed change too much.

Treatment: adjusted the distance between the phase detector and the reflective paper , different phase detectors emit different distances from receiving light.

3.

Failure 3 : the display measurement data is very small or even 0, and do not have any significant changes in the weight.

Treatment: adjust the sensor resistance or replacement sensor; check whether the connection between the output end of the sensor and the electrical direction is connected; check the self-check function of the electrical test box.

The above faults are only a few common problems in daily use. Of course, the structure of balance machine are complex, and there will be other problems.If there are another problems related to automatic balance machine, you can consult with our company.Hope you can pay attention to the precautions when using the automatic balancing machine to prevent unnecessary damage.

The balance machine cannot work properly：

1. The impact of the workpiece .

1)The balance precision cannot meet the workpiece balance requirement .

2)The workpiece supporting part is unsmooth .

3)The stiffness of the workpiece is not good.

4)Workpiece actual working state is inconsistent with the balance check state.

2.Influences of the balance machine:

1)The foundation of the balancing machine is not in accordance with the requirements, and it is easy to cause resonance.

2)The left and right supports are not in the same horizontal line, which can cause the rotor to move around.

3)Delta sensor output signal is abnormal.

4)The photoelectric sensor is not opposite to the reflective paper, which may lead to angular deviation.

Balance machine troubleshooting method

Troubleshoot the balance machine:

There are some glitches in the balance machine.However, these failures often lead to the machine inability to work properly,general factors that do not work properly maybe the from workpiece , balance machine itself and the circuit environment reason.

A. workpiece: the product parameters are beyond the scope of the detection range, and the product's own quality is not qualified.

B. balance machine: loose parts, damage and system failure.

C.circuit environment reason: whether voltage, current both match the balancing machine.

Cause of rotor imbalance?

We briefly describe the reasons that cause the rotor unbalance:

Installation error, when installing the quality center line of a part does not coincide with the rotation center line.

Casting porosity

Rotor deformation ,due to residual stress and uneven heating.

Sediment on the rotor.

Uneven planning, such as the motor rotor winding one side and the other side is uneven.

The rotor unbalance is caused by these reasons, all unbalance vector scattered on the rotor and can be considered to be focused in the "points" on a vector, dynamic balancing machine is to determine the location of the key points of unbalanced rotor and basis on a technology, then in the corresponding location remove or add a range of weights.
