Abstract

The invention discloses an ultrahigh pressure rotating sealed water jet cleaner. The ultrahigh pressure rotating sealed water jet cleaner is characterized by comprising a driving mechanism, a rotary sealing mechanism, a water inlet connecting member, a spray head mechanism, an upper casing and a lower casing, wherein the upper casing and the lower casing are fixedly connected; the rotary sealing mechanism comprises a water inlet pipe connector, a sealing outer casing, a sealing inner channel, a supporting shaft sleeve, a sealing medium channel and a driven gear. According to the ultrahigh pressure rotating sealed water jet cleaner disclosed by the invention, rotary dynamic sealing of ultrahigh water jet flow is realized by combined seal of end face seal and clearance seal; the seal between an ultrahigh pressure static part and a rotating part can be effectively realized; the utilization rate of high-pressure water is improved; the effect of removing rust by water jet is improved.

Description

technical field

[0001] The invention relates to a cleaner, in particular to an ultra-high pressure rotary sealed water jet cleaner. Background technique

[0002] The traditional water jet cleaning technology uses low-pressure hand-held spray guns, self-rotating nozzles and other equipment for cleaning. They have the characteristics of low cleaning efficiency, difficult real-time recovery of wastewater after cleaning, and easy return of rust during rust removal.

[0003] The traditional ultra-high pressure dynamic sealing structure mostly adopts self-tightening seal or piston ring seal. The former causes friction between the sealing channels due to the self-tightening effect of pressure, so that the rotating speed of the rotary nozzle cannot be increased; the latter is not suitable for poor lubricity and low viscosity. Ultra-high water jet rotary dynamic sealing occasions. The invention solves the difficult problem of realizing the high-speed rotation of the spray head under...
