Universal ZT ZT damping spring shock absorber damping spring shock absorber depending on the installation can be divided into three: 1, ZT-type shock absorber upper and lower seating surfaces with non-slip rubber mat, a smaller force to interfere with power equipment, Under ZT type shock absorber can be directly placed in the device base, can adjust the focus of any move, do not need fixing. 2, ZT-I type an upper fixed type. 3, ZT-Ⅱ type can be fixed up and down to suit a variety of installation needs. Using the highest quality spring steel, ZT-type shock absorber effect on 海松夏 available to more than 95%, service life of up to more than 10 years, is your best choice for Vibration and Noise! Low frequency and damping [ZT-type damping spring damper characteristics described] on 海松夏 ZT damping spring shock absorber (also known as prestressed spring shock absorber) has a steel spring damper dual advantages of large, eliminating steel spring phenomenon inherent resonance amplitude. The series of 29 kinds of specifications, which alone load 15kg-4800kg load the deal with all kinds of natural frequency of 1.6Hz-4.9Hz, damping ratio of 0.065. The series damper wide load range, user-friendly selection, low natural frequency, good isolation effect, and compact structure, small size, easy installation of replacement, safe and reliable, long working life, work environment adaptability. For active vibration isolation, passive vibration isolation, shock and vibration isolation and solid audio effects are obvious. A vibration isolation to reduce noise, vibration pollution control, environmental protection ideal damper. ZT damping spring shock absorber depending on the installation can be divided into three: 1, ZT-type shock absorber upper and lower seating surfaces with non-slip rubber mat, a smaller force to interfere with power equipment, can be directly ZT-type shock absorber set placed on the device under the base, adjust the focus to be easily moved, it does not need fixing. 2, ZT-I type an upper fixed type. 3, ZT-Ⅱ type can be fixed up and down to suit a variety of installation needs.
