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
Its disadvantages are: too high speed, too much noise, low cleaning efficiency, short service life and cannot be repaired after wear and tear, which is a one-time use product
The core part of the product of the American company adopts the cone surface gap seal, which has a small structure, but it also has the following disadvantages: ①The cone surface gap changes with the actual working pressure. Once the larger diameter dirt particles enter the cone surface sealing area, the rotating shaft is blocked. If it is stuck, the cleaning head will not rotate normally; ②The speed is still too fast and the leakage is large; ③The service life is short and the price is expensive

Abstract

The invention discloses a high pressure water rotating nozzle with an axial thrust self-balancing function. The high pressure water rotating nozzle with the axial thrust self-balancing function comprises a cleaning head with eccentric jetting holes in the same, a hollow cylindrical stepped rotation shaft, a stepped sealing outer shell and a water inlet joint, wherein the stepped sealing outer shell is provided with a cylindrical inner hole. The hollow cylindrical stepped rotation shaft penetrates into the stepped sealing outer shell with the cylindrical inner hole; the cleaning head is in threaded connection with the front end of the hollow cylindrical stepped rotation shaft; the water inlet joint with a sealing rod at the front end is screwed into a threaded hole in the rear end of the stepped sealing outer shell with the cylindrical inner hole; and the sealing rod at the front end of the water inlet joint penetrates into the hollow cylindrical stepped rotation shaft. The high pressure water rotating nozzle with the axial thrust self-balancing function is simple in structure and unique in design; the cylindrical stepped gap sealing technology is adopted by the hollow cylindrical stepped rotation shaft and the sealing effect is good; the over-speed rotating condition gets effective control further, the impact force of a water jet is improved, and the cleaning effect is good; and the maintenance and preservation are very convenient, and the using cost is largely lowered.

Description

Technical field [0001] The invention relates to the technical field of industrial cleaning, in particular to a high-pressure water rotary nozzle with an axial thrust self-balancing function. The product is mainly used in the high-pressure water cleaning industry for the cleaning of various heat exchanger tube scars and dirt. Background technique [0002] The industrial development of China's industrial cleaning industry started in the 1980s, far lagging behind developed countries such as Europe and the United States with a history of nearly a hundred years, and at first it was dominated by chemical cleaning. With the acceleration of my country's reform and opening up and modernization construction, and the strengthening of the people's awareness of environmental protection, the high-pressure water jet cleaning process is being accepted by more and more enterprises. There are three main reasons: (1) Fast cleaning; (2) Good cleaning effect; (3) No secondary pollution after cleaning....
