High difficulty is an ideal product for active and passive vibration isolation. ZD type damping butterfly valve electric butterfly valve has a wide load range and strong compliance. It can simultaneously produce obvious effects on active vibration isolation, passive vibration isolation and impact vibration isolation. It is a versatile vibration isolation product, suitable for working environments between - 20 ° C and 80 ° C, and is an ideal vibration reduction product for airborne equipment such as air conditioners, thermostatic equipment, fans, cooling towers, refrigeration units, compressors, pumps, etc.
Vibration isolation and noise reduction has been an important research area for a long time. The study of linear vibration isolation theory has been improved and widely used in engineering. Because the linear vibration isolation system is limited by the fact that the vibration isolation frequency must be more than 2 times of its natural frequency before it can be effective, people actively explore nonlinear vibration isolation solutions for low-frequency vibration isolation problems. The industrial air tension spring has the characteristics of low-frequency vibration isolation, which can ensure the strong bearing capacity of the whole system and outstanding vibration isolation.
After the birth of air tension spring, it has developed rapidly because of its outstanding functions. In addition to rail transit, industrial air tension springs are widely used for vibration isolation of cars and industrial machinery, vibration reduction of locomotive seats, vibration reduction of fine instruments and vibration control of fine test channels.
The industrial air tension spring uses air as the working medium, so the change of the ambient temperature will cause the change of the gas state parameters in its capsule, which will cause the capsule to deform to a certain extent. This kind of deformation is called the thermal expansion deformation of the air tension spring. The thermal expansion deformation will affect the mechanical stability of the equipment.
Industrial air tension spring is a non-metallic elastic element that takes part in the pressure air in a flexible and closed air bag and operates with the compressibility of air. Its elastic recovery force is supplied by the sum of the internal air compression reaction force and the reaction force caused by the change of the useful compression area of the air tension spring. It has the functions of buffering, vibration reduction and noise reduction. Compared with other elastic elements, industrial air tension spring has the advantages of nonlinear stiffness, low natural frequency, etc.
Industrial air tension spring has such excellent functions as low vibration isolation frequency (generally less than 2Hz), good damping function, adjustable functional parameters, and the ability to adjust the bearing size and isolator height by changing the air pressure in the bag. It has been used in vibration isolation of fine instruments, fine machinery, vehicle suspension equipment and stamping equipment, and has achieved good results.
