Working principle of drain cleaning machine:
Connect the pipe dredging nozzle to the high-pressure pump through a high-pressure hose, and place the nozzle directly at the pipe port that needs to be dredged. When the high-pressure pump is working, the reaction force generated by the high-pressure water sprayed from the back of the nozzle is used to push nozzle forward quickly, and use the high-pressure water jets generated by the nozzle in front and back to quickly clean the pipes. When the hose reel pulls the nozzle back, the high-pressure water flow discharges the dirt that has been washed away in the pipe outside the sewer pipe.
