Power washing apparatus

摘要: A portable, high-pressure, power washing system is described which includes an electric motor driven gear pump where the effectively water cooled by virtue of being contained in a thermally conductive housing surrounded insulating jacket through pumped made to flow before reaching pump's inlet port. The reduction mechanism such that relatively inexpensive, single-phase, series AC (universal) normally operating at high rpm can be employed. By proper dimensioning chamber relative drive and idler gears providing divider chamber's discharge orifice, pumping efficiency obtained. Completing assembly wand for directing pressure surface cleaned controlling on/off state motor.
