Installation of a MMC: attention to the environment
A MMC proffers be installed in different environments of work, which to a greater or lesser extent, they will be under the influence of the following external factors:
1 Dirt
- Clean environments
- Polluted environments: particulate matter (moisture, oil), other particles (dust)
2 Temperature / humidity
- Temporary thermal gradients
- Space thermal gradients
- Relative humidity.
3 Vibration
- Frequency
- Amplitude
According to these three variables you can act in different ways. One of them is to use a machine suitable, intended to ensure that its behavior is inert against any of these parameters. The other, provide the environment to let the machine safe from these disturbing factors.
To counter the effects of suspended particles the machine can carenar or even be pressurized internally to avoid that penetrating particles. On the other hand, can isolate the machine in a cabin.
In the case of thermal compensation we can speak of linear thermal compensation or structural thermal compensation. The compensation linear only considers the variation you can experience the linear sensor based the temperature while the structural, more complete, takes into account the effect of the variations of the temperature on the mechanical structure.
The option to use cabins with controlled temperature and humidity It depends on the size of the machine, since for large volumes option can result in a cost too high, while for volumes of 100 m2 may be that best option. It should be noted that, to avoid spatial gradients, it is say, to ensure that the temperature is identical anywhere in mechanics avoiding structural deformations, it is necessary to achieve a high recirculation of the air.
To eliminate the effect of vibration, there are two options: use a foundation or seismic mass either isolate exclusively through machine Active antivibrantes elements or liabilities (pneumatic shock absorbers, springs, elements) (viscous, etc.). Their use depends on the dimensions of the machine, and the amplitude and frequency of the vibrations. When the installation of one arises machine of measure in an industrial environment (presses for stamping, injection, lines) machining, forging, etc.), should conduct a detailed study of the vibrations.
