参考示意图，做一个血透机平衡腔的工作原理动画---**Text Extraction:**
费森尤斯4008系列血液透析机平衡腔系统由2个容积相等的腔体和安装其上的8个电磁阀(V31-V38)组成。
血液透析机平衡腔的容积在机器出厂时已经校正, 是固定值, 均为30mL。
每个腔体中由1块橡胶膜片将每1个腔体分为新鲜液腔F和废液腔A两个部分。
机器通过密闭的平衡腔系统来保证进入的新鲜透析液和排出的废液量始终保持相等, 由此保持了流量的平衡稳定。
平衡腔系统根据8个电磁阀的切换组合, 主要形成以下几种平衡腔的工作模式。
**Chart Description:**
* **Type:** Flowchart/Diagram illustrating a fluid system.
* **Main Elements:**
* Two vertical chamber units (labeled 68). Each unit is divided internally by a vertical line into two sections: F1 and A1 in the left unit, and F2 and A2 in the right unit.
* Valves: Eight valves represented by crossed lines within triangular shapes, labeled 30, 31, 32, 33, 34, 35, 36, 37, 38.
* Lines: Represent fluid paths, colored brown and green. Arrows indicate potential flow direction on lines connecting to valves 32 and 33.
* Pump/Flow sensor: A circular element with an internal hourglass-like symbol, labeled 21.
* Labels: Numeric labels for valves (30-38), chambers (68), pump (21), and a line (88C). Section labels within chambers (F1, A1, F2, A2).
* Connections:
* A brown line enters from the top, connected to valve 30. This line then splits and connects to valves 31, 32, 33, 34.
* Valves 31 and 32 connect the upper brown line to the top of the left chamber (68). Valve 32 has upward/downward arrows.
* Valves 33 and 34 connect the upper brown line to the top of the right chamber (68). Valve 33 has upward/downward arrows.
* Valves 35 and 36 connect the bottom of the left chamber (68) to a lower green line. Valve 36 connects to a green line labeled 88C. Valve 35 connects to a brown line that leads to element 21.
* Valves 37 and 38 connect the bottom of the right chamber (68) to the lower green line. Valve 37 connects to the green line labeled 88C. Valve 38 connects to the brown line that leads to element 21.
* Element 21 is connected to valve 35 and 38 via brown lines, and a brown line continues to the right from 21.
* A green line labeled 88C enters from the left and connects to valves 36 and 37.

机器的流量控制(FlowControl)
上述平衡腔周期之间的切换是通过流量泵(FlowPump) 21电机负载感应电流脉冲来实现的。当平衡腔内的膜片触到腔壁时, 相应的压力增大, 流量泵21的电机感应电流增加, 产生1个感应脉冲, 并且在转换期间, 即每当腔体充盈, 橡胶膜片... (Text is cut off)
