Embodiment 1

[0012] Embodiment 1 Composition of a high-pressure water jet derusting equipment for railway freight cars and the effects of each part:

[0013] A high-pressure water jet derusting equipment for railway wagon vehicles, comprising mainly a power unit 1, an oil pump 2, an oil-water booster 3, an accumulator 4, a high-pressure rubber hose 5, a spray gun 6, a gun shaft 7, a spray head 8, a nozzle 9, The control system 10 is composed of, and it is characterized in that the high-pressure oil pump 2 is connected with the oil-water supercharger 3, and after the normal water is pressurized, it enters the spray gun 6 through the accumulator 4. The power unit 1 is a Cummins six-cylinder diesel engine with a power of 75-90kW and a maximum working pressure of 250 MPa. The spray gun 6 is a pneumatic rotary spray gun or a hydraulic rotary spray gun driven by compressed air or hydraulic pressure. The nozzle 9 is a fan nozzle.

Embodiment 2

[0014] Embodiment 2 A kind of working process of the high-pressure water jet derusting equipment of railway wagon vehicle:

[0015] Pull the railway wagon to the derusting room, start the power unit 1 and the oil pump 2, so that the ordinary water enters the spray gun 6 through the accumulator 4 after being pressurized. For the same main engine, one machine with one gun, one machine with two guns, one machine with three guns or one machine with four guns can be selected according to the corrosion status of the steel structure of the car body.

Abstract

The invention relates to high-pressure water-jet rust removing equipment for a wagon, which mainly comprises a power device 1, an oil pump 2, an oil-water booster 3, an energy accumulator 4, a high-pressure rubber tube 5, a spray gun 6, a gun barrel 7, a sprayer 8, a spray nozzle 9 and a control system 10, and is characterized in that the oil pump 2 is connected with the oil-water booster 3, and after being pressurized, common water enters into the spray gun 6 through the energy accumulator 4. The high-pressure water-jet rust removing equipment provided by the invention has the benefits as follows: energy conservation and emission reduction are realized, high-pressure water-jet cleaning can not cause secondary pollution, and secondary cleaning treatment is not required after the treatment; the degree of mechanization for high-pressure water-jet rust removing is high, the cleaning efficiency is high, the descaling capability is strong, and the cost is low.

Description

technical field [0001] The invention relates to high-pressure water jet derusting equipment for railway wagons, which is mainly used for derusting and cleaning steel hooks of railway wagon bodies, and belongs to the technical field of special equipment for railway wagon maintenance. Background technique [0002] At present, the rust removal of the steel hooks of the domestic railway freight car body mainly adopts the method of shot blasting. This method needs to collect and process a large amount of dust generated in the process of shot blasting, and consumes a large amount of compressed air at the same time. Contents of the invention [0003] The object of the present invention is to provide a high-pressure water jet derusting equipment for railway wagons that overcomes the above technical deficiencies, so that the railway wagons can be derusted cleanly without dust treatment, reducing the consumption of compressed air. In order to realize the object of the above invent...
