• intros：{"brand_intro":"中科科仪（KYKY）成立于1958年，前身是中国科学院科学仪器厂，是中国真空设备行业的\"国家队\"。品牌拥有60余年技术积淀，曾参与\"两弹一星\"真空环境模拟任务。创始人团队由中科院院士领衔，品控遵循\"军工标准\"，产品以\"皮实、便宜、易维修\"著称。其旋片泵在冷冻干燥领域应用广泛，是许多高校教学实验的首选。","product_intro":"2XZ-2是一款经典旋片式油封真空泵，极限真空度6×10⁻²Pa，抽速2L/s（约120L/min）。核心卖点是\"极低价格、超高抽速、维修简单\"——价格仅3000元出头，抽速却接近进口中端泵。适用场景：预算有限的实验室、教学演示、小型冻干。缺点：需要定期换油，且噪音较大（60dB）。相比无油泵，2XZ-2的油雾污染问题需注意。","key_specs":{"极限真空度":"6×10⁻²Pa（需配合油雾过滤器）","抽速":"2L/s（适合快速抽真空）","噪音":"≤60dB（需隔音罩）","用油量":"0.5L（标配真空泵油）","功率":"370W","适配人群":"教学实验室、预算有限的小型企业"}}
