大孔径 SV07B-M 是一款面向更大计量体积工况的定量阀。陶瓷转子在陶瓷定子内转动,转子沟槽舀起固定体积的液体,并从入口带到选定出口。液体仅接触这两个陶瓷零件,因此流路呈化学惰性且不含金属。
两种阀头覆盖全范围:TC20QP-B 为 2.0 mm 流道,沟槽容积 15、37 与 31 微升;TC20QSP-B 为 3.0 mm 流道,沟槽容积 115 与 94 微升。端口间容积为 106 至 283 微升。驱动力 8 N/m,整机重量 0.85 kg。
该选哪种阀头?
TC20QP-B 为 2.0 mm 流道,提供 6、8、10 通道,沟槽容积 15、37 与 31 微升。TC20QSP-B 为 3.0 mm 流道,提供 6 或 8 通道,沟槽容积 115 与 94 微升。
8 N/m 驱动力为何重要?
沟槽越大携带液体越多,转子遇到的阻力也越大。更大的驱动力可在试剂黏稠或阀门长期静置时,仍保持计量可重复。
该阀可处理哪些液体?
液体仅接触氧化铝陶瓷,因此在 100 摄氏度限值内可使用强腐蚀性试剂与高纯水。请针对具体介质确认密封件兼容性。
能否脱离上位机运行?
可以。RS232 或 RS485 串口指令可直接驱动,PLC 也可通过 Modbus 控制。ASCII 与 Modbus 在同一硬件上可用。
