Vibration speed sensor installation method

Regarding the installation method of the vibration speed sensor, the four installation methods of the vibration speed sensor, the installation of the vibration sensor usually adopts four methods: hand holding on site, plasticine sticky water magnetic sucker fixing, and bolt fixing.

How to install the vibration speed sensor
Vibration velocity sensors are usually used to measure the vibration of bearings, and in a few cases, they are also used to measure the vibration of rotating shafts.

When measuring the vibration velocity, if the sensor is installed incorrectly or not firmly, the measurement result will be distorted or the sensor will be damaged due to vibration. Therefore, the installation method of the vibration velocity sensor should be carefully selected.

When the sensor is used to measure the vibration of the rotating shaft, the installation usually adopts four methods: hand holding, plasticine sticky water magnetic chuck, and bolt fixing on site. In the temporary vibration measurement, most of the hand-held sensors are used. This method is flexible and easy to use, especially when the number of vibration velocity sensors is lacking and the interchangeability of the sensors is not good. It has special advantages; the disadvantage is that the test The error is relatively large, and the work intensity is also high.

It is also more convenient to stick the sensor with plasticine, and the accuracy of the measurement result will be much better than that of hand-held. Note that the plasticine cannot paste the vibration velocity sensor on a vertical plane, it can only be fixed on a horizontal plane, such as measuring the vertical, horizontal and axial vibration of the top of the bearing seat. When the bonding is firm and the frequency is 50Hz, the method can vibrate with a maximum energy of 300μm.

Another disadvantage of plasticine is that the adhesive force is greatly affected by temperature. Higher and lower temperatures will significantly reduce the adhesive force. The speed sensor measured in the bearing; it should not be used when the bearing temperature is too low during cold start in winter.

It is more convenient to fix the speed sensor with a permanent magnet chuck than plasticine. At present, permanent magnet chucks with a size of φ50 or 50mm*50mm can also be manufactured in China. The suction force can reach 196N. Use such a suction cup to fix the vibration speed below 500g The sensor, adsorbed on a horizontal surface, can measure vibrations up to 1000μm. The disadvantage is that the surface of the bearing seat of the general unit is coated with mud or paint, which will reduce the suction of the suction cup. Therefore, when it is adsorbed on a vertical plane and the amplitude is large, it needs to be assisted by a handrail to prevent the sensor from falling off and being damaged.

Fixing the speed sensor directly on the bearing with bolts not only can reliably measure the vibration in three directions on the top of the bearing housing, but also can measure the vibration in two directions on the vertical plane. This installation method is the strongest of the four installation methods.

In short, the installation of the vibration velocity sensor depends on the needs of the measurement and according to different working environments, choose the most suitable one of the above four methods, so as to ensure the smooth progress of the measurement and reduce the measurement and test errors.
