所述液晶显示单元8包含液晶显示装置和键盘。 The liquid crystal display unit 8 includes a liquid crystal display device and a keyboard.

在使用过程中，水位测量装置3测量准确的水位信号，传输至控制器7中，控制器7设定好的具体时间日期与北京时间同步，并且设置电费的阶梯电价。首先通过水位测量装置3检测井下水仓1水位，当水位在高水位时并且时间在低电价时间，控制器7即可打开电动球阀一10、电动球阀二13和射流泵9，实现水泵的抽真空作业，当负压传感器11输出给控制器7的信号达到开泵压力时，控制器7先关闭电动球阀一10、电动球阀二13和射流泵9后打开水泵2、电动闸阀14来进行排水作业，同时正压传感器12检测输出水压，超声波流量计4检测水的流量，液晶显示单元8显示各种参数；当水位测量装置3检测到水位到超低水位时，将信号传输至控制器7，控制器7控制电动闸阀14关闭后，再控制水泵2停止。 During use, the water level measuring device 3 measures an accurate water level signal and transmits it to the controller 7. The specific time and date set by the controller 7 are synchronized with Beijing time, and a tiered electricity price is set. First, the water level of the downhole water tank 1 is detected by the water level measuring device 3. When the water level is at a high water level and the time is at a low electricity price time, the controller 7 can open the electric ball valve 1 10, the electric ball valve 2 13 and the jet pump 9 to realize pumping of the water pump. For vacuum operation, when the signal output by the negative pressure sensor 11 to the controller 7 reaches the pump opening pressure, the controller 7 first closes the electric ball valve 10, the electric ball valve 2 13 and the jet pump 9, and then opens the water pump 2 and the electric gate valve 14 to drain water At the same time, the positive pressure sensor 12 detects the output water pressure, the ultrasonic flowmeter 4 detects the flow of water, and the liquid crystal display unit 8 displays various parameters; when the water level measuring device 3 detects that the water level reaches an ultra-low water level, the signal is transmitted to the controller 7.
