Embodiment 1

[0026] Embodiment 1 Installation: Fix both ends of the inner hole of the hydraulic pipe fitting between the tapered nozzle 121 and the ejector pin 131, push the ejector pin 131 to clamp the hydraulic pipe fitting, and close the rear cover 13;

[0027] Liquid injection: heat the descaling liquid to 50℃, and inject it from the descaling liquid tank 2 through the large nozzle hole 1211 and the small nozzle hole 1212 of the nozzle 121 into the inner wall of the hydraulic pipe fitting to clean the inner wall of the pipe; at the same time, it is injected into the cylinder through the auxiliary nozzle 122 Clean the outer wall of hydraulic pipe fittings;

[0028] Soaking and flushing: the pipe fittings are soaked and flushed for 7 minutes; during this process, the pressure in the cylinder body 11 and the hydraulic pipe fittings are respectively adjusted through the auxiliary drain hole 132 and the drain hole 1311;

[0029] Take the parts, open the back end cover 13, push the thimble 131 to l...

Embodiment 2

[0030] Embodiment 2: Installation and pickup will not be repeated:

[0031] Liquid injection: heat the descaling liquid to 55℃, and inject it from the descaling liquid tank 2 through the large orifice 1211 and the small orifice 1212 of the nozzle 121 into the inner cavity of the hydraulic pipe to clean the inner wall of the pipe; at the same time, it is injected into the cylinder through the auxiliary nozzle 122 Clean the outer wall of hydraulic pipe fittings;

[0032] Soaking and flushing: The pipe fittings are soaked and flushed for 6 inches; during this process, the pressure in the cylinder body 11 and the hydraulic pipe fittings is adjusted through the auxiliary drain hole 132 and the drain hole 1311 respectively.

Embodiment 3

[0033] Embodiment 3: Installation and pickup will not be repeated:

[0034] Liquid injection: heat the descaling liquid to 60℃, and inject it from the descaling liquid tank 2 through the large nozzle hole 1211 and the small nozzle hole 1212 of the nozzle 121 into the inner cavity of the hydraulic pipe to clean the inner wall of the pipe; at the same time, it is injected into the cylinder through the auxiliary nozzle 122 Clean the outer wall of hydraulic pipe fittings;

[0035] Soaking and flushing: the pipe fittings are soaked and flushed for 5 minutes; in this process, the pressure in the cylinder body 11 and the hydraulic pipe fittings are adjusted through the auxiliary drain hole 132 and the drain hole 1311 respectively.

Abstract

The invention relates to the technical field of rust cleaning of hydraulic pipe fittings, in particular to a high pressure rust cleaning device and method of the hydraulic pipe fittings. The high pressure rust cleaning device comprises a rust cleaning fluid box body connected with a machine body, and the machine body comprises a tubular barrel body, a front end cover which is fixedly arranged, a rear end which is movably arranged, a spray nozzle arranged on the front end cover, and a thimble which is arranged on the rear end cover. The spray nozzle is a conical pressurizing nozzle, a large spray hole is formed in the middle of the spray nozzle, a plurality of small spray holes are evenly distributed in the side wall of the spray nozzle, and the spray nozzle is connected with the rust cleaning fluid box through a pipeline. The thimble is conical, a drainage hole is formed in the middle of the thimble, and a one-way pressure relief valve is arranged in the drainage hole. The rust cleaning of the hydraulic pipe fittings has the advantages that high pressure rust cleaning is achieved, and the rust cleaning efficiency is improved.

Description

Technical field [0001] The invention relates to the technical field of rust removal of hydraulic pipe fittings, in particular to a high-pressure rust removal device and method for hydraulic pipe fittings. Background technique [0002] The hydraulic pipe fittings of hydraulic equipment are often rusted due to the influence of natural environment such as rainfall during use. Especially in coastal areas, the equipment is easy to rust because the equipment is easily exposed to salty water vapor. Corroded pipe fittings cannot be derusted, which will cause stress defects on the pipe wall. Under the pressure of the hydraulic pipeline, the pipe fittings will be damaged. In severe cases, the entire equipment or personnel will be damaged. Summary of the invention [0003] The purpose of the present invention is to provide a high-pressure rust removal device and method for hydraulic pipe fittings. [0004] The present invention is realized by the following technical solutions, including a rus...
