How to choose the right spring shock absorber

How to choose the suitable shock absorber: Spring shock absorber is mainly used for vibration isolation of high frequency mechanical equipment such as fans, air conditioning boxes, air conditioning units, generator sets, air compressors, water pumps, cooling towers and so on. But low frequency composite rubber shock absorbers, suspension shock absorbers and spring shock absorbers are very different.

How to choose a suitable spring shock absorber

1. The load of the spring shock absorber should include the total weight of the damping equipment W(kg). Choose an even number of support points, should not be less than four. Spring shock absorbers should accept static load.

2. Determine the type of spring shock absorber; First select the spring shock absorber, whose P value is close to the P2 value.

3. In order to meet the damping effect, it is necessary to check the resonance of the spring shock absorber with high-speed rotating species under periodic load;

4. When selecting the spring shock absorber, pay attention to the change of the total weight of the equipment under dynamic conditions. When the equipment is unstable under dynamic load, 6 or more spring shock absorbers should be selected.

The main advantages of spring shock absorbers used in transformers are as follows

1. High vibration reduction power. Transformer vibration can be regarded as high frequency vibration, and the natural frequency value of the TB spring damper is as low as 3-5 Hz. Used in transformer vibration isolation, vibration reduction power is higher than 98%;

2. Easy equipment. Spring shock absorbers can adjust the horizontal height of the transformer. For the equipment site with uneven base, the uneven ground can be compensated by adjusting the height of the shock absorber;

3. Long service life. Shell material is ductile iron 450. Durable; Appearance hot dip galvanized, not easy to rust, service life of more than 20 years. Many shock absorber products on the market are general cast iron, simple cracking, not affected by impact; The appearance of many products is only general spray paint, no rust;

4. A large number of transformers have been used and verified, and the effect is really good.

The use of spring shock absorbers

According to the type and function of different, suitable for transformer, elevator and other equipment spring shock absorber; Hoisting damping of various pipes, fan coils, fresh air units, variable air volume air conditioning boxes, axial flow fans, etc., or high-frequency damping of impact machinery such as punching machines and forging presses, is the ideal method to block vibration, reduce noise, control vibration pollution, and protect the environment.
