Ultrahigh-pressure water jet cleaning spray head

Abstract

The invention relates to the technical field of cleaning equipment, and provides an ultrahigh-pressure water jet cleaning spray head. The cleaning spray head comprises a fixing base with a first through hole, a shell with a cavity, a rotating shaft with a second through hole and a spray head with a spray hole, wherein the spray hole is formed in a deflection mode, one end of the fixing base is connected with a water inlet high-pressure pipe, the other end of the fixing base is connected with the shell, the rotating shaft is arranged in the cavity and is in clearance fit with the inner wall ofthe cavity, one end extends out of the shell and is connected with the spray head, the other end is in clearance fit with the inner wall of the first through hole, the first through hole communicateswith the second through hole, a step is arranged in the cavity, a supporting part is arranged on the rotating shaft, the supporting part is matched with the step to limit and install the rotating shaft in the cavity, a rebound cavity is formed, a rebound hole is formed in the rotating shaft, the rebound hole communicates with the second through hole and the rebound cavity, and a centripetal conical groove is formed in the side, close to the step, of the supporting part and used for reducing centrifugal force deflection generated in the rotating process of the rotating shaft, improving the stability of axial rotation and prolonging the service life.

Description

technical field

[0001] The invention relates to the technical field of cleaning equipment, in particular to an ultra-high pressure water jet cleaning nozzle. Background technique

[0002] With the rapid development of modern industry, the use of cooling water is increasing. During the heat exchange process of cooling water, calcium and magnesium originally dissolved in water will precipitate carbon dioxide under the action of temperature to form calcium carbonate and slightly soluble in water. Magnesium carbonate, when these crystals are continuously deposited inside the tube bundle of the heat exchanger, hard scales are formed, which affects the cooling efficiency. It is necessary to periodically clean these dirts to make the equipment operate normally. Traditional chemical cleaning will discharge a large amount of acid, which will corrode the equipment and form loopholes. In addition, the cleaning waste is toxic and requires a lot of money for wastewater treatment, causing...
