ZTA type circulating pump spring shock absorber in Wuhan Metro Line 6

The ZTA type circulating pump spring shock absorber (patented product) has the double advantages of low frequency and large damping of the steel spring damper, and eliminates the inherent resonance amplitude phenomenon of the steel spring.

Product features:

1. The outer shell is made of high-quality steel, and the shock absorber will never break during transportation and operation, thus improving the service life of the shock absorber.
2. Wide load range, easy for users to choose, low natural frequency, good vibration isolation effect, compact structure, small overall size, easy installation and replacement, safe and reliable use, and long service life.
3. It has strong adaptability to the working environment and can work normally at – 40 ℃ – 110 ℃. It has obvious effects on active vibration isolation, passive vibration isolation, impact vibration and solid sound transmission. It is an ideal shock absorber to isolate vibration, reduce noise, control vibration pollution and protect the environment.
