The invention discloses high-pressure cleaning equipment. The high-pressure cleaning equipment comprises a liquid supplying device, a cleaning spraying device and a control device. The liquid supplying device comprises a liquid storage box and a high-pressure pump used for pressurizing water inside the liquid storage box for outputting; the cleaning spraying device comprises a cleaning chamber, a clamping part arranged inside the cleaning chamber and used for clamping a part to be cleaned and a cleaning assembly which is arranged inside the cleaning chamber and communicated with a liquid outlet of the high-pressure pump; the control device controls water supplying of the liquid supplying device and spraying cleaning of the cleaning spraying device. A control system is utilized for controlling the liquid supplying device to automatically output high-pressure cleaning fluid to the cleaning assembly and controlling moving of the cleaning assembly to apply automatic cleaning on the part to be cleaned with fixed time, fixed distance, a fixed portion and variable pressure. Cleaning speed is high, and production efficiency is greatly improved; scrapping of parts is reduced, and the production cost is lowered.
