Installation of fixed / online infrared thermometer Notes
Installation of fixed / online infrared thermometer precautions Jin Taike instrument today for everyone to explain the installation of fixed / online infrared thermometer technical knowledge, when we install the thermometer, when the thermometer is used to measure shaft vibration, The installation is usually carried out in four ways: hand-holding on the site, plasticine sticky water magnetic chucks, and bolts. In the temporary vibration measurement, most of them use the handheld thermometer, which is flexible and easy to use. Especially when the number of smart infrared thermometers is lacking and the interchangeability of thermometers is not good, there are special The disadvantage is that the test error is relatively large and the work intensity is also large. Or it is better to use a gimbal directly to the place where the temperature is measured.

For example, we use the first method of sticking and sticking a thermometer like a thermometer. It's more convenient and the accuracy of measurement results is much better than that of a handheld. The squeegee is not capable of affixing the smart infrared thermometer to the vertical plane, but it can only be fixed on the horizontal plane, for example, measuring the vertical, horizontal, and axial vibrations at 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.
But here we must also know that plasticine has a drawback, that is, the adhesive force is greatly affected by the temperature, the higher and the lower temperature will make the adhesive force significantly reduced, so it is not suitable for high temperature and high temperature turbine The speedometer is measured in the bearings of the rotor and the reeled wheel; during the cold start in winter, the bearing temperature is too low to be used. Therefore, the low temperature of the object can be completely glued with plasticine. For the long-term consideration, the most suitable one is the universal bracket, and the direct fixing is the most reliable.
The second method is that permanent magnet suction cup fixed speed thermometer is more convenient than plasticine, and at present domestic can produce permanent magnet suction cup with size φ50 or 50mm*50mm. Its suction power can reach 196N. The infrared smart thermometer with a suction cup fixed below 500g absorbs on the horizontal surface and can measure up to 1000μm vibration. The disadvantage is that the surface of the general unit bearing seat is coated with mud or paint, which will cause the suction force of the suction cup to decrease. Therefore, when it is adsorbed on the vertical plane and the amplitude is large, it needs to be assisted by the handrail to prevent the thermometer from falling off and breaking. .
The third kind we explained is to fasten the speedometer to the bearing directly with the bolt universal bracket. It can not only measure the vibration in the three directions of the top of the bearing housing reliably, but also measure the vibration in two directions on the vertical plane. This mounting method is the strongest of several mounting methods. The above three installation methods hope to help everyone.
