Nowadays, more and more attention is paid to environmental protection, and the requirements for some noise are also very high. When the glass fiber reinforced plastic acid resistant vacuum pump vibrates, it may produce some noise, which has an impact on the surrounding environment. Here we will introduce the solution to the vibration of the acid resistant glass fiber reinforced plastic vacuum pump.
1、 Installation of spring isolator:
1. Selection of spring vibration isolator style for vacuum pump:
Generally, self supporting spring shock absorber is selected, which has the advantages of simple structure and low cost; the spring is exposed, which is convenient to observe the spring state at any time, and the spring to be replaced shall be disposed in advance to avoid sudden settlement of vacuum pump, equipment damage and pipeline breakage caused by excessive spring corrosion.
2. Spring selection:
Generally, the spring selected by the shock absorber manufacturer shall meet the following requirements: the spring diameter shall not be less than 0.8 times of its height under the rated load; the spring must have a certain additional stroke; the vortex flowmeter shall be at least equal to 50% of the rated static deflection; the horizontal stiffness of the spring shall be at least 100% of the rigid steel to ensure the stability of the shock absorber.
3. The selection of spring damper deflection;
Generally, the rated deflection (spring compression) of the arch spring damper proposed by the shock absorber manufacturer is generally 25 mm (the self frequency value is about 3-4hz), which can be used for vibration isolation of vacuum pump at 650 rpm. When the speed is lower than 650, spring isolators with deflection below 40 are recommended.
2、 Installation of rubber vibration isolator:
Selection of rubber vibration isolator: materials are generally chloroprene rubber (C.R) and natural rubber (N.R); compression type rubber shock absorber is generally used, and shear type rubber shock absorber can be selected for light weight vacuum pump; compared with spring damper, rubber vibration absorber has relatively poor vibration isolation performance.
3、 Installation of Sui base:
In order to meet the more stringent vibration system standard, it is undoubtedly the best choice to use spring vibration isolator when installing Sui sex base.
The content of the above three aspects is to solve the vibration method of acid resistant glass fiber reinforced plastic vacuum pump, you can refer to it, applied to the actual production, can reduce the impact on the environment.
