A. application field The mobile sewer cleaning machine is mainly used to get rid of the clog and filth in the pipe.B. working principleThe sewer cleaning machine is equipped with high pressure pump powered by diesel to clean the pipe depending on a thrust force on the nozzle from high pressure water jetting. When the nozzle reaches the pipe end, the high pressure hose will be forced to move back due to a pulling force from roller and meanwhile,the high pressure water blast also cleans the pipe walls with carrying the filth outside.C. advantages The sewer cleaning machine has been regarded as a necessity for modern production due to the following characteristics : a. advanced structure b.fresh modelc. convenient operation and maintenanceD. technical parametersPERFORMANCE MODELUDOR-VIUDOR-VIIUDOR-VIIIDiesel Power KW444444High pressure pumpHigh pressure pump modelV100/150V130/120V150/120Rated pressure MPa151212Flow L/min)100125150RollerRoller speed (m/min)151515Roller lift force (N)200020002000NOZZLEJet angle °15/2515/2515/25HoseID (mm)161616Length (m)606060Cleaner pipe diameter(mm)500500600
