Problems solved by technology
[0004] Since the vibration isolators are all high pressure devices (about 20MPa to 30MPa), the strength of the rubber is not enough to maintain the high pressure for a long time, so the service life is extremely short
[0005] However, the combined structure of the metal piston rod and rubber bladder / rubber membrane has excessive friction between the piston rod and the rubber, resulting in excessive dynamic stiffness of the molecular spring vibration isolator, affecting the natural frequency of the vibration isolation system, and further affecting the vibration isolator. The problem of vibration isolation performance

The invention relates to a piston type molecular spring vibration isolator which comprises a base, a cavity cover, a piston rod, a sealing seat and a limiting seat. According to the piston type molecular spring vibration isolator, a telescopic structure of the piston is adopted for transmitting vibration, so that the problem that traditional rubber is poor in strength is solved, friction between metal and rubber does not exist, high pressure bearing in the vibration isolator is guaranteed, and the piston type molecular spring vibration isolator has the three landmark characteristics of being large in damping, low in rigidity and high in bearing capacity.
Description
Technical field [0001] The present invention relates to a piston-type molecular spring isolator belongs to the technical field of vibration damping devices. Background technique [0002] The molecular spring blocking technology is a molecular spring mixing medium to form a molecular spring mixing medium using water and porous hydrophobic material. When the molecular spring mixing medium is applied, the water molecules will enter the hydrophobic nanoporous nanoporous porous hydrophobic material, when the pressure is unloaded, the water molecules are from micro Yeling is escorted, achieving energy storage and release, thereby eliminating vibration. [0003] The vibration isolator designed by the molecular spring blocking technology is already provided in the prior art. Most of these vibration isolats use a rubber sac or metal piston rod in combination of rubber capsule / rubber membrane. [0004] Since the vibration isolator is high pressure (about 20 MPa to 30 MPa), the strength o...
