How to detect whether the bearing is damaged and how to maintain it?

There are many methods to detect bearing faults, and the accuracy of bearing fault detection is also very high. The easiest way to measure bearings is to buy a bearing fault detector, which Xunxiang Technology has. Generally, the normal bearing rotation is a low hum, and the abnormal bearing will have sharp noise.

There are several cases of bearing fault detector: it can filter out low-frequency vibration caused by structural problems such as shaft rotation and imbalance, misalignment and looseness, and use envelope demodulation and amplification technology to measure the envelope value of high-frequency acceleration caused by bearing defects or gear meshing problems, which is very suitable for early detection of potential faults of machines and bearings. At this time, you have to use the bearing fault diagnosis instrument.

Main detection technical indicators:

1. Vibration sensor: shear piezoelectric accelerometer.

2. Measuring range, frequency response range and accuracy:

Vibration displacement (peak-to-peak): (1 ~ 1999) μ m, (5 ~ 10k) Hz (5% 2 words)

Vibration speed (true effective value): (0. 1 ~ 199.9) mm/s, (5 ~ 10k) Hz (5% 2 words).

Vibration acceleration (peak value): (0. 1 ~ 199.9) m /S2, (5 ~ 10k) Hz (5% 2 words).

High frequency acceleration: (0.00 1 ~ 25) m /S2.

3. Working temperature: (-20 ~ 80)℃.

4. Battery: 6F22 9V, which can work continuously for more than 25 hours.

5. Weight: about 250g (including battery and sensor).
