[0037] 步骤之二: 液位传感器所受压力达到输送流体介质装置 12起动运行的上限预设 定值, 液位传感器将起动输送流体介质装置 12的信号经信号线传输给控制柜 1 ;
[0038] 步骤之三: 输送流体介质装置 12受控制柜 1控制起动运行, 进入正常运行状态 , 流质池中的液体经输送流体介质装置 12防腐过滤器 8进流质口进入出流管, 被 抽离流质池;
[0039] 步骤之四: 在所述步骤之三步骤的同吋, 电控阀 112打幵, 电控阀 13关闭, 滤网 过滤沉淀积累的污物从电控阀 112流出, 回流落入液池中;
[0040] 步骤之五: 在输送流体介质装置 12停止工作之前, 电控阀 112关闭, 电控阀 13打 幵, 经过滤的洁净流质进入检测保护管 5, 所述第一单向阀 4和第二单向阀 15在 该液体的压力作用下, 阀芯 16向下运动, 即此弹簧被压缩, 导致阀芯 16与阀体 的壁紧密贴合, 液体无法通过该单向阀, 被封存在检测保护管 5内;
[0041] 步骤之六: 输送流体介质装置 12在运行过程中池中的液位和检测保护管 5的液 位同步下降, 当液位下降到液位下限 9, 检测保护管 5内液位也下降到下限; [0042] 步骤之七: 液位传感器所受压力达到下限设定值吋, 液位传感器将停止输送流 体介质装置 12运行的信号经信号线传输给控制柜 1, 受控制柜 1控制输送流体介 质装置 12停止运行;
[0043] 步骤之八: 当输送流体介质装置 12停止工作之后, 被封存在检测保护管 5内的 液体压力下降, 弹簧的弹力大于保护管内液体的压力吋, 弹簧原先被压缩的弹 性势能弹顶托举阀芯 16向上运动, 阀芯 16与阀体的壁又保持一定距离, 液体沿 阀芯 16的斜面流下, 冲刷所述液位传感器; 第二单向阀 15因为液体压力的降低 , 也回复到保持通气的导通状态;
[0044] 步骤之九: 被封存在检测保护管 5内的液体流回流质池以后, 所述第一第二单 向阀均保持导通状态, 用于在正常使用状态下通气, 大气沿所述阀芯斜面通出 , 使得检测保护管 5内外的压力值相等;
[0045] 步骤之十: 若液位传感器 6失灵, 池内流质降到液位下限 9吋输送流体介质装置 12没有停止工作, 当降到液位极限 21吋, 断电传感器 22传输断电信号给控制柜 1 , 输送流体介质装置 12断电, 强制停止抽排流质, 同吋幵启闪光灯和鸣笛报警 器, 提示巡査的工作人员检修。 。
