High-pressure water cleaning self-rotating spray head adopting front diversion structure design

Abstract

A high-pressure water cleaning self-rotating spray head adopting a front diversion structure design comprises a cleaning head with eccentric spray holes, a combined rotating body composed of a sealed bush and a shell and a water inflow joint. The high-pressure water cleaning self-rotating spray head is characterized in that through a gap sealing technology adopted between the front diversion structure design on the rotating body and a thin shaft at the front end of the water inflow joint, a water film is generated between the rotating body and the water inflow joint thin shaft, the axial force is balanced automatically, and the cleaning head can be directly mounted at the headmost end of the spray head without a bearing; the water inflow joint and the sealed bush are each provided with a through hole; after flowing through the through hole in the water inflow joint, high pressure water enters an inner cavity of the cleaning head after flowing through a water groove in the sealed bush, a diversion groove, the through hole in the sealed bush and a water hole and then is sprayed out through eccentric spray holes in the cleaning head; and the cleaning head and the combined rotating body rotate immediately, and thus the function of efficiently cleaning scabs and dirt in pipelines is achieved.

Description

technical field [0001] The invention relates to a self-rotating spray head for high-pressure water cleaning with a front diversion structure design, which belongs to the technical field of industrial cleaning. The product is mainly used for cleaning pipeline scars and dirt in the high-pressure water cleaning industry. Background technique [0002] The industrial development of China's industrial cleaning industry started in the 1980s, far behind developed countries such as Europe and the United States with a history of nearly a hundred years, and initially focused on chemical cleaning. With the acceleration of my country's reform and opening up and the pace of modernization, and the strengthening of people's awareness of environmental protection, the high-pressure water jet cleaning process is being accepted by more and more companies. There are three main reasons: (1) Fast cleaning speed, (2) Good cleaning effect, (3) No secondary pollution after cleaning. [0003] The high...

Problems solved by technology

The previous high-pressure water self-rotating cleaning nozzles basically rely on bearings to bear axial and radial loads, and there are the following shortcomings in the actual application process: (1) The outer diameter is too large to meet the requirements of cleaning smaller inner diameter pipelines (2) Because the bearing is selected in the structural design, it is necessary to design a seal with sealing and dustproof functions for the bearing. In the harsh working environment where high-pressure water and dirt particles coexist, the service life of the seal is extremely Short, once the seal is damaged, the internal bearing is damaged

Although this product has filled the gap in the country, reduced user costs, and reduced dependence on similar foreign products, its processing accuracy requirements are extremely high, and manufacturing is very difficult, making it difficult to significantly reduce production costs
