(2) Flow Rate: Factors include flushing power and impact frequency. The higher the flow rate, the greater the cleaning efficiency. Through our experiments and practice, at a pressure of 1350bar, a flow rate of 44L/min ensures simultaneous operation of 8 nozzles, expanding the rotating cleaning surface. Time: The longer the time, the higher the cleaning frequency and efficiency. Requirement: 2 minutes per pipe, equivalent to 4 seconds each for the upper and lower pipes, 60 seconds forward and 20-40 seconds backward for other 10-meter long pipes, approximately 0.18 meters per second. 8-nozzle ultra-high-pressure jet rotation cleaning, requiring a speed of 420rpm or higher, adjustable.

(4)喷射 Method: The cleaning ability and efficiency are primarily determined by the combination of spray distance, spray angle, and nozzle quantity. This proposal utilizes Jincheng's (精诚) diamond nozzles with an oblique forward angle of 45° and 8 water nozzles.
