Embodiment Construction

[0046] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0047] The invention is mainly applied to the cleaning of metal surfaces, such as the cleaning of a large number of marine organisms attached to the bottom of ships, the cleaning of grease in the pipelines of petroleum heat exchangers, and the rust removal, paint removal and polishing of metal surfaces. The cleaning rate of the present invention to the above-mentioned stains is 100%. Compared with domestic products, the cleaning efficiency is increased by 30%, and the service life is 120 hours, far exceeding the existing domestic products. Reduce the cost of using consumables such as nozzles.

Abstract

The invention discloses an ultrahigh-pressure water jet rotary cleaning nozzle with a cutting function. The ultrahigh-pressure water jet rotary cleaning nozzle comprises a nozzle body (1), a rotary mandrel (2), a shell body (3) and a connecting section (4). The rotary mandrel (2) is divided into three parts. The central axes of part of water holes in the nozzle body (1) are parallel to the centralaxis of the nozzle body (1), the central axes of the rest of water holes in the nozzle body (1) and the central axis of the nozzle body (1) form certain angles, and the central axes of the rest of water holes in the nozzle body (1) and the central axis of the nozzle body (1) form angles that are all different. When ultrahigh-pressure water is sprayed out of the water holes in the nozzle body (1),the nozzle body (1) and the rotary mandrel (2) are driven to rotate as a whole, and the ultrahigh-pressure water jet rotary cleaning nozzle is used for removing rust, oil, paint, marine organisms, salt, alkaline, scale and other dirt on metal outer surfaces or pipeline inner walls or the like and can also be used for polishing metal surfaces.

Description

technical field [0001] The invention relates to an ultra-high pressure water jet rotary cleaning nozzle with a cutting function, belonging to the field of ultra-high pressure water jet cleaning Background technique [0002] High-pressure water jet cleaning is a new cleaning technology developed in the 1970s. 10MPa<water pressure≤100MPa, high-pressure water jet cleaning has become the main cleaning technology in industrially developed countries, occupying a major share of the cleaning market. For example, US petrochemical companies use high-pressure water jet cleaning for more than 80% of heat exchange equipment, and the proportion of chemical cleaning is only about 5%. At present, research institutions have also carried out in-depth research on the theory of water jet cleaning and the development of various cleaning equipment. Now they have entered the field of ultra-high pressure cleaning technology, that is, the water pressure exceeds 100MPa. Ultra-high pressure water j...
