Magnetically-braked noise-reducing high-pressure water rotating nozzle

Abstract

The invention provides a magnetically-braked noise-reducing high-pressure water rotating nozzle. The magnetically-braked noise-reducing high-pressure water rotating nozzle comprises a rotating head, a rotating shaft protection sleeve, a connecting magnetic component, a rotating shaft component and a shell. An eccentric hole is drilled in the rotating head, and the hollow rotating head is connected with the front end of the rotating shaft component in a threaded manner and comprises an outer layer made of titanium alloy and a middle layer made of a rubber noise-eliminating material. The rotating shaft component is fixedly connected with the connecting magnetic component in a threaded manner, a linear braking part is arranged outside the connecting magnetic component and is fixedly connected with the shell in a threaded manner, an annular step is arranged on the inner side of the shell, the rotating shaft component is mounted in the shell and comprises a hollow steplike rotating shaft and a hollow clearance seal rod mounted in the hollow rotating shaft, and the rotating shaft is fixed in the shell through a bearing. The magnetically-braked noise-reducing high-pressure water rotating nozzle has the advantages of better cleaning effect, simpler structure, good noise-reducing effect and long service life.

Description

technical field [0001] The invention relates to the field of industrial cleaning, in particular to a magnetically braked high-pressure water noise-reducing rotary spray head. 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 ...

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 also produces a lot of noise when cutting objects, which is very harmful to the health of the operator. Therefore, the system must be silenced. The existing method is to protect the noise. That is, let the operator wear earplugs
