　　下水道清洗機
　　Sewer Cleaning Machine
　　移動式下水道清洗機用于疏通、清除管道中的堵淤和污物。它以柴油機為動力驅動高壓泵運轉，利用高壓水射流在噴頭上產生的推進力疏通管道。當噴頭到達管端時，膠管在卷管器拉力作用下強制后移，至使高壓水射流束清掃管壁并將雜物帶至管外，以達到清洗管道的目的。該清洗機采用液壓馬達驅動節流調速的控制油路及以操縱盤為中心的集中控制方式，結構*、造型新穎、操作和使用方便，是現代化生產的管道疏通和清洗設備。
　　The sewer cleaning machine is mainly used to get rid of the clog and filth in the pipe.The 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.The high pressure hose will be forced to move back due to a pulling force from the roller when the nozzle reaches the pipe end and meanwhile,the high pressure water blast also clean the pipe walls with carrying the filth outside.
　　The machine has been regarded as a necessity for modern production due to the advanced structure,fresh model,convenient operation and maintenance.
