FIELD: process engineering.SUBSTANCE: invention relates to high-pressure cleaner, primarily, high-pressure washing plant. Claimed cleaner comprises at least one pump unit (powered pump assembly) with motor and suction pipeline. Cleanser transferred by pump assembly (34) is used for cooling of motor (22) and its jacket (32) by forcing cleanser fluid via cooling channel (42) for heat rejection. Cooling channel (42) surrounds the motor jacket (32). Pump unit assembly (12, 120, 140) comprises at least one heat conducting separator (48) to space cooling channel (42) apart from motor jacket (32).EFFECT: higher safety of pump unit.24 cl, 8 dwg |
