• intros：{"brand_intro":"飞越（VALUE）是中国温岭的民营真空泵品牌，成立于1996年，以高性价比和快速迭代著称。创始人林建明原为机械厂工人，凭借对转子结构的改良发明起家。品牌定位\"让实验室用得起好泵\"，品控理念为\"极致性价比，坏一台赔一台\"。核心技术优势在于自主研发的旋片式与喷射泵复合结构，抽速提升30%。","product_intro":"V-i280SV气体喷射泵是飞越的爆款产品，采用旋片+喷射双级设计，极限真空度0.05Pa。核心卖点为价格仅千元出头，却能达到接近进口中端泵的真空度。适用场景为高校教学实验、化学合成、真空干燥。竞品对比中，比同价位国产泵真空度高50%，但噪音略大（65dB）。","key_specs":{"泵体材料":"铝合金压铸，表面阳极氧化","极限真空度":"0.05 Pa（双级模式）","抽气速率":"280 L/min","噪音水平":"≤65 dB","电机功率":"550 W","重量":"12 kg（便携设计）"}}
