(2) Flow Rate: Factors include flushing capability 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 that 8 nozzles can operate simultaneously, increasing 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 for each end, 60 seconds forward and 20-40 seconds backward for other 16 seconds on a 10-meter long pipe, 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 overall combination of the jet distance, jet angle, and nozzle quantity. This proposal utilizes Jincheng's (Jingcheng) diamond nozzles with an oblique forward angle of 45° and 8 water jets.
