How about the isolation effect of rubber shock absorber
When it comes to shock absorbers, ordinary people think of spring shock absorbers, and then rubber shock absorbers. Perhaps because spring shock absorbers accept relatively large vibration amplitude, such as the spring shock absorbers used in cars, the effect is relatively obvious, while rubber shock absorbers accept less vibration amplitude than spring shock absorbers, but since this product has been consumed, It absolutely has its commonality and common use.
In fact, the rubber shock absorber has a great advantage that it has a strong vibration isolation effect for high frequency vibration, because the rubber in the rubber shock absorber is highly elastic and viscoelastic. In this way, the high frequency vibration can be accepted, so the rubber shock absorber is used most frequently in transportation tools.
It has significant effects on vibration and noise reduction of mechanical equipment and noise transmission of pipeline system, and further eliminates the impact of sound bridge on structural buildings. Hanging rubber pneumatic butterfly valve is a vibration reduction measure that cannot be ignored. It has large deformation range and low natural frequency.
The working temperature of rubber shock absorber is - 15 ℃~+70 ℃. When the temperature changes, the stiffness also changes. Damping ratio C/CO>0.07. Positive vibration isolation of mechanical equipment such as water pump, compressor, fan, refrigerator, generator set, diesel set and negative vibration isolation of instruments and meters have good vibration isolation effect.

What is an electromagnetic flowmeter? It is a new type of flow measurement instrument developed rapidly with the development of electronic technology in the 1950s and 1960s. Electromagnetic flowmeter is an instrument that measures the flow of conductive fluid according to the aerodynamic force induced by the conductive fluid passing through the external magnetic field by applying the principle of electromagnetic induction. What is the working principle of electromagnetic flowmeter? What are its characteristics? Let's go on to understand.
