Product Introduction:
Variable damping rubber isolation feet are commonly used as high-precision and high-efficiency protective foundations for mechanical equipment and assemblies, to prevent the impact caused by ground vibration or to prevent the vibration generated by the equipment itself from affecting the use of surrounding high standard instruments and equipment on the ground. The tower shaped isolation feet are made of high-quality synthetic rubber and metal parts, which can achieve efficient isolation without horizontal tilting or excessive deformation. Internally designed with adjustable damping, the damping value can be adjusted according to the vibration effect of the usage environment. The bottom plate is equipped with anti slip rubber pads, which do not require the isolation foot base to be fixed on the ground during use. The position can be changed freely, making it convenient and flexible.
Variable damping isolation footrest is an essential basic equipment used in high-tech research, precision machining, and precision testing to eliminate the impact of environmental vibration on machining accuracy and testing. This product uses a lower natural frequency to effectively avoid resonance phenomena caused by environmental vibrations, control amplitude amplification, reduce vibration transmission rate, and ensure high precision in processing and testing.
Application scope:
This product is widely used for vibration reduction and isolation of various precision instruments, precision mechanical equipment, precision machining, precision measurement, etc. (such as isolation of electric printing machine vibration, air conditioner vibration, stamping vibration, forging vibration, etc.). It is suitable for high-precision reciprocating motion vibration control, control of external vibration sources in laser optical experiments, self vibration control of lithography machines and optical processing equipment, dynamic control and application of micro vibration in biomedical module clamps and various electrophysiological experiments.
Product features:
The variable damping isolation foot base has a scientifically reasonable structure, and the airbag is a key component of this product. It uses multi-layer composite rubber material, with a butyl rubber inner layer to improve the airtightness of the product; The outer layer is made of natural rubber with anti-aging layer to improve the strength of the product and increase the fatigue strength and anti-aging service life of the product. The outer layer of the airbag is made of steel, which is used to stabilize the design form of the product, achieve stability and reliability during use, and can adapt well to various complex environments. The product base is made of high-strength steel precision die casting, and the bottom plate is finely processed with sinking holes. The inflation and damping adjustment valve body can be connected by embedded standard screws.
Damping function:
In order to achieve efficient damping effect, our company divides the internal air chamber of this series of products into two layers, fully considering the volume ratio of the upper and lower air chambers inside the foot seat and the size relationship of the damping holes between the two chambers. The dual chamber pneumatic isolation system will produce low-frequency alternating deformation due to the response excited by environmental vibration during operation, causing the flow of gas through the throttle damping holes to change its own direction of motion in each forced cycle to generate damping force and reduce the natural frequency. The two chambers are connected by an external air pipe, and the end is equipped with a variable damping valve, which can adjust the damping effect externally.
