Allowable vibration value of equipment in production operation area - national standard allowable value

Allowable vibration value of equipment in production operation area - national standard allowable value

From the perspective of physics and physiology, the human body is a complex system. If human is regarded as a mechanical system, it contains a number of linear and nonlinear "components", and the mechanical properties are very unstable. People have great differences in height, weight, bones, muscles and other aspects, especially when it comes to psychological effects, the situation is more complicated. According to the frequency range, vibration is divided into low frequency vibration (below 30Hz), medium frequency vibration (30 ~ 100Hz) and high frequency vibration (above 100Hz). The human can feel the vibration frequency range is 1 ~ 100Hz. Experiments show that people are most sensitive to vibration sensation with a frequency of 2-12Hz, and the sensitivity decreases gradually when the frequency is higher than 12Hz or lower than 2Hz. The most harmful vibration frequencies to the human body are those that coincide with the natural frequencies of certain organs of the human body (i.e. resonate). These natural frequencies are around 6Hz for the human body, 8Hz for the internal organs, 25Hz for the head, and 250Hz for the nervous center.

How to solve the vibration problem of roof equipment?

How to solve the vibration problem of roof equipment?

Analysis of current situation: Due to the shortage of building space and the change of building function, many developers have focused on the empty space on the top floor of the building. In order to make more reasonable use of space and many functional buildings such as hotels, factories and office buildings have strong requirements on the internal infrastructure of the building, such as ventilation, heating, cooling and drinking water system, so the developer will install a lot of corresponding equipment on the roof of the building, such as air conditioning host water host The problem of floor vibration after the installation of these mechanical equipment such as large pumps is also exposed, so how to solve the vibration problem of the equipment on the top floor of the building is an urgent problem that we need to solve and pay attention to.

Application of rubber shock absorber

Application of rubber shock absorber

It is possible that a lot of people are showing their noses at the mention of rubber shock absorbers, thinking that rubber shock absorbers are of no use at all for shock absorption, or very little use, and generally have a bad impression on rubber shock absorbers. For such a phenomenon is mostly caused by those substandard cheap rubber shock absorbers on the market at present, because those inferior rubber shock absorbers cut corners in the production process. A large number of adding machines are doped in rubber, and the content of rubber is very small, so that it loses the original function and effect of rubber, or it can not be called rubber shock absorber at all.
