Tanya pembaca: How To Check Motor Vibration?

What is use for vibration test on motor?

Noise and Vibration testing is used for preventative maintenance, reducing the chance of breakdowns by analysing any change in the noises or vibrations coming from the motor – any deviation found can then be used to diagnose and repair problems that could lead to motor failure down the line.

What is vibration in motor?

Vibration is simply a back and forth movement—or oscillation—of machines and components in motorized equipment. Vibration in industrial equipment can be a symptom, or cause, of a problem, or it can be associated with normal operation. As machine speed increases the effects of imbalance become greater.

How do you stop motor vibration?

An easy method to reduce vibration is to install a clean damper on the rear shaft of the motor. Clean dampers are basically hermetically sealed plastic cases with an inertia body packed with silicon gel. The extra inertia and silicon gel help absorb the vibration and provides a stable damping effect.

What causes motor vibration?

The main causes of motor vibration include, but are not limited to an electronic or mechanical imbalance, faulty gears, failed bearings, loose foundations, wear and tear or misalignment. Imbalances: An imbalance is like a weighted spot in the rotating component of a motor.

How do you check your vibration sensation?

To test vibration sense, the examiner places a finger under the patient’s distal interphalangeal joint and presses a lightly tapped 128-cycle tuning fork on top of the joint. The patient should note the end of vibration about the same time as the examiner, who feels it through the patient’s joint.

How do I know my vibration level?

A typical vibration measurement system includes a device to sense the vibration (accelerometer), and an instrument to measure the level of vibration. This equipment also has settings for measuring frequency, a frequency-weighting network, and a display such as a meter, printer or recorder.

What are the 3 basic characteristics measured in vibration?

How far (amplitude or intensity), and how fast (frequency) the object moves helps determine its vibrational characteristics. The terms used to describe this movement are frequency, amplitude and acceleration.

What is excessive vibration?

Vibration can cause changes in tendons, muscles, bones and joints, and can affect the nervous system. Collectively, these effects are known as Hand-Arm Vibration Syndrome (HAVS). Workers affected by HAVS commonly report: attacks of whitening (blanching) of one or more fingers when exposed to cold.

How can I make a vibration motor at home?

A quick and dirty way to make a vibrating motor without any extra parts is to take a computer fan and snap off half of the fan blades with a pair of pliers. This will make the fan off-balanced and vibrate.

What are the types of vibration?

A vibrating motion can be oscillating, reciprocating, or periodic. Vibration can also be either harmonic or random. Harmonic vibration occurs when a vibration’s frequency and magnitude are constant. A vibration is random when the frequency and magnitude vary with time.

Why does a motor vibrate horizontally?

High horizontal readings are commonly associated with unbalance in the rotating elements. High axial readings generally indicate misalignment. The cause may be external, like coupling misalignment, or internal, like mechanical looseness or a bent shaft.

How can vibration be minimized?

The primary method of reducing noise and vibration is to minimize their generation. This can be accomplished by: Balancing rotating components. Reducing the mass of reciprocating members.
