High pressure water noise-reduction spinning nozzle

Abstract

The invention provides a high pressure water noise-reduction spinning nozzle which comprises a rotary head, a rotary shaft assembly, a shell and a water inlet connector. An eccentric hole is drilled in the rotary head. The rotary head is connected with the front end of the rotary shaft assembly through threads and is of a hollow structure. The outer layer of the rotary head is made from titanium alloy materials, and a middle layer of the rotary head is made from rubber anechoic materials. Annular ladder type steps are arranged on the inner side of the shell. The rotary shaft assembly is installed in the shell. The rotary shaft assembly is composed of a hollow rotary shaft and a hollow gap sealing rod. The gap sealing rod is installed in the hollow rotary shaft. The rotary shaft is fixed in the shell through a front deep groove ball bearing, a rear deep groove ball bearing and a thrust bearing. The two ends of the rotary shaft are provided with oil seals. Compared with the prior art, the high pressure water noise-reduction spinning nozzle has the remarkable advantages and beneficial effects that water jet hitting power is improved, a cleaning effect is better, the structure is more simple, disassembly, assembly and replacement are more convent and faster, a noise reduction effect is good, noise can reach industrial noise standards, and large-range application can be achieved.

Description

technical field [0001] The invention relates to the field of industrial cleaning, in particular to a high-pressure water noise-reducing rotary nozzle. Background technique [0002] The high-pressure water self-rotating nozzle is an efficient and multi-purpose water jet cleaning tool, which is always available in cleaning equipment. However, due to the fact that there is still a certain gap between my country's high-end mechanical product manufacturing level and developed countries such as Europe and the United States, so far, all such products used in China are imported from abroad. The applicant once disclosed a small high-pressure water automatic The rotating cleaning nozzle reduces the cleaning cost and reduces the dependence on foreign products. At the same time, it further reduces the rotating speed, improves the cleaning efficiency and prolongs the service life. However, the rotating part adopts a gap seal, which is difficult to process and high in production cost. It i...

However, due to the fact that there is still a certain gap between my country's high-end mechanical product manufacturing level and developed countries such as Europe and the United States, so far, all such products used in China are imported from abroad. The applicant once disclosed a small high-pressure water automatic The rotating cleaning nozzle reduces the cleaning cost and reduces the dependence on foreign products. At the same time, it further reduces the rotating speed, improves the cleaning efficiency and prolongs the service life. However, the rotating part adopts a gap seal, which is difficult to process and high in production cost. Not conducive to a wide range of applications of the product

In addition, the high-pressure water jet working system will also produce a lot of noise when it is working, which is very harmful to the health of the operators. Therefore, the system must be silenced. The existing method is to protect the noise, that is, Have operators wear earplugs
