Zhejiang Vacuum Pump Factory as a professional manufacturer of vacuum pumps, after several years concluded that several ways to solve the vibration of the vacuum pump for your reference. First, the installation of rubber vibration isolator: rubber vibration isolator options: The material is generally neoprene (CR), natural rubber (NR); generally use compression rubber shock absorber, for lighter weight vacuum pump, optional Shear-type rubber shock absorber; compared to the spring shock absorber, rubber shock absorber vibration isolation performance is relatively more difference. Second, the installation of spring isolators: 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 need Replace the spring ahead of schedule, to avoid excessive damage to the spring corrosion, resulting in sudden vacuum pump caused by equipment damage and pipeline rupture and other phenomena. 2, the choice of spring: General shock absorber manufacturers need to meet the following requirements of the spring: the diameter of the spring should not be less than 0.8 times the height of its rated load; spring must have some extra travel, vortex flowmeter at least equal to the rated static 50% of the deflection; the horizontal stiffness of the spring is at least 100% of the rigidity of the steel to ensure the stability of the shock absorber. 3, the choice of spring shock absorber deflection; usually shock absorber manufacturer arch spring shock absorber rated deflection (spring rated compression) is generally 25MM (from the frequency value of about 3-4HZ), this deflection should be 650 Vibration isolation of the vacuum pump per minute. When the speed is lower than 650, it is recommended to use spring isolators with deflection below 40. Third, the installation of inertia base: In order to meet the more stringent vibration system standards, installation of inertia base, with the use of spring isolators, is undoubtedly the best choice. The specifications of the inertia base: the base weight is about 1-2 times the weight of the vacuum pump; the frame is formed by the locking of the channel, the height of not less than 1/12 of the length, but not less than 150MM, not more than 300MM; Wide size should be able to cover the entire vacuum pump, and more than 10-15 cm each side is appropriate. And best to cover the bayou; watering cement, and built a layer of steel mesh at one-third of the height; installation of spring isolator base and base spacing to 3-5 cm.
