High pressure system for cleaning surfaces with high pressure fluid jet, comprises pressure conduit for adjusting volume flow rate in specified range, where pressure conduit with bent spiral section is arranged as metallic pressure pipe

摘要

The system comprises a pressure conduit (2) for adjusting the volume flow rate, during operation, in the range between 10 to 30 liters per minute, preferably 25 liters per minute. The pressure conduit is arranged as a metallic pressure pipe. The inside diameter of the pressure conduit ranges between 4.8 to 8 millimeter, preferably 6 millimeter. A spiral section of the pressure conduit is bent so that the pressure conduit has flexibility for adjusting the high pressure nozzle (1).
