Nowadays, the society pays more and more attention to the environmental protection problems, and the requirements for some noise are also very high, the reducer parts may produce some sound when vibrating, so how to mitigate it?
Selection of spring isolator style for speed reducer parts:
General selection of self-supporting spring damper, its advantages of simple structure, low cost; spring exposed, easy to observe the spring state at any time, for the need to replace the spring in advance of the disposal, in order to avoid excessive damage to the spring corrosion, caused by the vacuum pump sudden settlement caused by the damage to the equipment and pipeline ripped off the phenomenon.
Spring selection:
General vibration damper manufacturers choose the spring to meet the following requirements: the spring diameter should be not less than 0.8 times its height under the rated load; the spring shall have a certain amount of extra travel, vortex flowmeter at least equal to the rated static deflection of the 50%; the spring's horizontal stiffness of at least 100% of the straightness of the steel in order to ensure the stability of the damper.
Selection of spring damper deflection: Usually, the rated deflection of the spring damper proposed by the damper manufacturer is generally 25MM (from the frequency value of about 3-4HZ), and this deflection can be applied to the vibration isolation of the vacuum pump at 650 revolutions per minute. When the rotational speed is lower than 650, it is recommended to use a spring isolator with a deflection of 40 or less.
Addition of a sui-base:
In order to meet the more stringent standards of vibration control, the addition of a sui-base, together with the use of a spring isolator, is undoubtedly the best choice.
Add rubber vibration isolators:
Rubber vibration isolator selection: the material is generally neoprene (C.R), natural rubber (N.R); generally choose compression type rubber vibration isolator, for the lighter weight of the vacuum pump, you can choose the shear type rubber vibration isolator; compared with the spring vibration isolator, the rubber vibration isolation performance of rubber vibration isolation performance is relatively poor.
