How to deal with water ring vacuum pump vibration phenomenon?

Nowadays, society is attaching more and more importance to environmental protection issues, and its requirements for some noises are very high. Some vibration may occur when the water ring vacuum pump vibrates, which will affect the surroundings. The following is a brief introduction of water ring Vacuum pump vibration approach.

First, install spring isolator:

1, the choice of vacuum pump spring isolator style:

The general use of self-standing spring shock absorber, the advantages of simple structure, low cost; spring exposed, easy to observe the spring state at any time, for the spring to be replaced ahead of schedule to prevent excessive damage to the spring corrosion, causing sudden vacuum pump caused by equipment Damage and pipeline rupture and so on.

2, the choice of spring:

General shock absorber manufacturers to choose the spring to meet the following requirements: The diameter of the spring should not be less than 0.8 times its height under the rated load; the spring must have some extra travel, vortex flowmeter at least equal to 50% of the static deflection; Spring The level of rigidity is at least 100% of the rigidity of steel to ensure the stability of shock absorber.

3, the choice of spring shock absorber deflection;

Generally, the shock absorber manufacturer's rated deflection (spring rated compression) is generally 25mm (from the frequency of about 3-4HZ), the deflection should be at 650 rpm vibration isolation of the vacuum pump. When the speed is lower than 650, it is recommended to use spring isolators with deflection below 40.

Second, install rubber vibration isolator:

The choice of rubber vibration isolator: the material is generally neoprene (CR), natural rubber (NR); generally use compression rubber shock absorber, for the lighter weight of the vacuum pump, the choice of shear rubber shock absorber; phase More than the spring shock absorber, rubber shock absorber vibration performance is relatively more difference.

Third, the installation of inertia base:

In order to meet the more stringent vibration standards, the installation of inertia base, with the use of spring isolators, is undoubtedly the best choice.

The above three aspects of content is to solve the water ring vibration of the vacuum pump method, we can refer to the use of actual production, can reduce the impact on the environment.
