How to choose an isolator: precise matching strategy from parameters to scene

The selection of isolators directly affects the operational stability of precision equipment, especially in high-precision fields such as optics and semiconductors. Incorrect selection may lead to experimental data deviation or equipment damage. This article analyzes how to scientifically select isolators from three dimensions: parameter matching, scene adaptation, and brand reliability.

1、 Choosing an isolator requires core parameter matching: the golden triangle of frequency, load, and damping

The natural frequency of the isolator needs to be much lower than the operating frequency of the equipment (usually 1/√ 2 times). For example, LeadTop’s POT-G series hollow cone rubber isolator has a natural frequency of 4-8Hz, which can effectively isolate mid to high frequency vibrations (such as personnel movement and equipment vibration) and avoid resonance amplification.

The load range should cover the weight of the equipment, and the POT-G series supports a load of 50-700kg, suitable for small and medium-sized equipment such as microscopes and optical detectors. The damping coefficient determines the vibration attenuation speed. The high damping design of POT-G shortens the recovery period by 30% and reduces equipment shaking time.

2、 Scene adaptation of isolators: differentiated requirements between laboratory and industrial environments

The laboratory scene needs to balance vibration isolation and convenience. LeadTop’s ZDT-B series swing rod air floating vibration isolator adopts automatic leveling technology, which does not require manual calibration, and the silent design (<40dB) avoids interference with the experimental environment. In industrial scenarios, impact resistance is required.

The ZDT-B series, with its ultra-thin composite airbag structure, can withstand instantaneous impact loads and achieve vertical/horizontal isolation efficiencies of 86-92%/88-94%, meeting the requirements of high-precision equipment such as laser interferometers.

3、 Reliability of brand isolators: guarantee for long-term stable operation

Choosing an isolator requires attention to the brand’s technical accumulation and after-sales service. As a professional supplier of vibration isolation optical platforms, LeadTop’s products have passed ISO 9001 certification. Both POT-G and ZDT-B series offer a 5-year warranty and support customized adjustment systems (such as optional casters and precision level gauges) to reduce user maintenance costs.

summary

The selection of isolators should be based on parameter matching, combined with scenario requirements and brand reliability for comprehensive decision-making. LeadTop’s POT-G and ZDT-B series, with their differentiated designs, cover all needs from laboratory to industrial scenarios, providing dual protection of “low-frequency isolation+high-frequency attenuation” for precision equipment.
