Cleaning spraying nozzle and cleaning method for high pressure cleaner

Abstract

The invention relates to the technical field of arrangement of spraying nozzles during cleaning, in particular to a spraying nozzle for rotating to clean deep holes and a cleaning method for a high pressure cleaner. The spraying nozzle comprises a spraying nozzle head body, the spraying nozzle head body is provided with two spraying holes and two fan-shaped flow guiding grooves, the cross sectional area of a single fan-shaped flow guiding groove is roughly a half of that of a gun body flow guiding hole, high pressure water flowing to the fan-shaped flow guiding grooves from a high pressure spraying nozzle gun body is contracted so as to reduce bounce of the high pressure water, the spraying holes are vertical to the flow guiding grooves, each spraying hole corresponds to one flow guiding groove, and the depth of the spraying holes is increased so that the amplitude angles of the sprayed flow from the spraying holes are smaller than 5 degrees. The sprayed flow angles from the spraying holes are small, so that the stress is centralized, large impact forces can be generated, good cleaning effects are achieved, when deep holes and blind holes are cleaned, one rotating period, same position and two-time cleaning are achieved, and the cleaning efficiency is increased.

Description

[technical field] [0001] The invention relates to the technical field of arrangement of nozzles in cleaning, in particular to a nozzle for rotating and cleaning deep holes for a high-pressure cleaning machine and a cleaning method thereof. [Background technique] [0002] In aerospace precision parts, automotive parts such as steering pumps, crankshafts, etc., as well as mechanical devices in construction machinery and other industries, there are blind holes and deep holes in the workpiece. According to the requirements of production accuracy and use accuracy, after the blind hole, deep hole, etc. are processed, they need to be cleaned to remove burrs, oil stains, etc. [0003] In the prior art, there is a nozzle device for cleaning vehicle window glass with the publication number CN101022981A, which has multiple nozzles and can increase the cleaning area, but the cleaning strength of this device is general, and the stress is not concentrated enough, so the cleaning efficienc...

AI Technical Summary

Problems solved by technology

Although this technology reduces the hydraulic loss of water flow to a certain extent, the depth of the spray hole of this structure is relatively short, resulting in a large water outlet angle, divergent water column, and small spray force, which affects the cleaning effect.
