Hydraulic system pipeline decontamination device under gas-liquid combined excitation

The utility model relates to a hydraulic system pipeline decontamination device under gas-liquid combined excitation. The device is a new technology and a new method for cleaning of hydraulic systems, particularly hydraulic systems with severe working conditions and complicated structures, by adopting a brand-new excitation principle. The system consists of a great number of components such as integrated blocks, joints, pipeline and hydraulic valves, pollutant removal is carried out by adopting the gas-liquid combined excitation, and the cleaning efficiency is higher. The hydraulic system pipeline decontamination device can replace an existing method of manual cleaning after the system is detached or a cleaning method by purely adopting a flushing pump, stepless regulation of gas-liquid two-phase exciting parameters can be conveniently realized for different hydraulic systems, and the hydraulic system pipeline decontamination device is energy-saving, environment-friendly, remarkable in economical benefit and the like.
