产品概述

SY-03B 是一款围绕集成式陶瓷切换阀打造的高精度微量注射泵,在单一模块内同时提供大容量注射器支持、高速度与严格的体积控制,面向色谱自动进样 OEM 及其它需要精准进样与干净切换的分析流体路径。

梯形丝杆(导程 6 mm)驱动 60 mm 额定行程、共 6000 步,单步分辨率 0.01 mm,纯水介质下线速 0.01–60 mm/s,单程运行时间 1–6000 s。液体体积误差不超过额定行程的 1%,重复性误差 0.3%–0.5%,相邻口切换不超过 1 s,整机由 DC24V/3A 供电,重 2.2 kg。

典型应用

选型须知

  1. 注射器范围 50 uL–25 mL,同一台泵可兼顾分析回路与大体积分配;精度与重复性指标按额定行程计。
  2. 集成式陶瓷切换阀在 1 s 以内完成相邻口切换,保证自动进样流程中清洗与选择序列的高效。
  3. 6 mm 导程丝杆提供了本泵标称的更高线速;集成前请按注射器规格与液体粘度确认驱动扭矩。

常见问题

SY-03B 支持多大体积?

可选注射器覆盖 50 uL–25 mL,由 60 mm 额定行程驱动。

精度如何?

液体体积误差不超过额定行程的 1%,额定行程下重复性误差 0.3%–0.5%。

为什么用陶瓷切换阀?

氧化铝陶瓷湿件耐磨损、耐化学腐蚀,且一体式阀可在 1 s 以内完成相邻口切换。

通常集成在哪些场景?

主要面向色谱自动进样 OEM 及需要高速高精度进样的分析仪器。
