1 工艺控制要求 （1）粗格栅及提升泵站 粗格栅运行的控制：用超声波液位差计来测量粗格栅前后的液位差，当液位差值达到设定值时，或者当液位差值在规定的时间内未达到设定值时，均用电动阀门自动开启粗格栅除污机，完成一个运行周期后停止运行。栅渣通过皮带输送机输送到螺旋压榨机最后外运。皮带输送机与粗格栅机联动控制，任意回转式格栅除污机启动后应启动皮带输送机联动运行。 潜污泵的控制：在潜污泵有压力指示，开泵时应先开水泵，当达到一定压力时用电动阀门自动打开。进水泵房有潜污泵5台，2台备用。考虑到其中2台作为长期备用，又易发生设备故障，故实际使用中设置成轮流启动方式，以达到既有备用，又不让其长期搁置不用的目的。 （2）细格栅及沉砂池 细格栅运行的控制：用超声波液位差计来测量细格栅前后的液位差，当液位差值达到设定值时，或者当液位差值在规定的时间内未达到设定值时，均用电动阀门自动开启细格栅除污机，完成一个运行周期后停止运行。 沉砂池控制：沉砂池由一系列 success. Some machining workshops find it difficult to process titanium effectively, but this view does not represent the development trend of modern machining methods and tools. The difficulty is partly due to the lack of experience that can be used for reference because titanium metal processing is an emerging process. In addition, difficulties are usually related to expectations and operator experience. In particular, some people have been used to the processing methods of materials such as cast iron or low alloy steel, and the processing requirements of these materials are generally very low. In contrast, machining titanium seems more difficult because the same tool and the same rate cannot be used, and the tool life is different. Even compared with some stainless steels, titanium processing is still more difficult. We can certainly say that different cutting speeds, feed rates and certain preventive measures must be taken to process titanium. In fact, compared with most materials, titanium is also a completely direct processable material. As long as the titanium workpiece is stable, the clamping is firm, the machine tool is selected correctly, the power is appropriate, the working condition is good, and the ISO 50 spindle with short tool suspension is equipped, all problems will be solved - as long as the cutting tool is correct. However, in practical milling, the
