Embodiment 1

[0026] Such as figure 1 , figure 2 with image 3 As shown, the spraying support of the long rod spray gun of this embodiment includes a bearing 1, a barrel sleeve 2, a support rod 3, and a base 6. The bearing 1 is fixed on the upper end of the support rod 3. Specifically, the upper end of the support rod 3 is cut outside For the outer ring of the bearing 1, the outer ring of the bearing 1 is fixed to the upper end of the strut 3 by welding. The barrel sleeve 2 is fixed on the inner ring of the bearing 1, and the central axis of the barrel sleeve 2 and the central axis of the bearing 1 are parallel to each other. Specifically, the barrel sleeve 2 is inscribed in the inner ring of the bearing 1, and the barrel sleeve 2 It is fixed to the inner ring of the bearing 1 by welding, and the gun barrel 2 and the bearing 1 constitute the rotating mechanism of the spraying bracket of the long-barrel spray gun of this embodiment. The upper end of the base 6 is provided with a connecting ...

Embodiment 2

[0052] The spraying bracket of the long rod spray gun of this embodiment has the same basic structure as that of the embodiment 1, and the difference is that the bearing 1 is a deep groove ball bearing, and the inner ring of the bearing 1 has a diameter of 150 mm.

[0053] The spraying process for the inner wall of the metal pipe of this embodiment includes the following steps:

[0054] Step 1. Inner wall substrate treatment:

[0055] Prepare the metal pipe to be sprayed, and the inner diameter of the metal pipe is greater than the diameter of the circular atomization surface of the long rod spray gun, and the inner wall of the metal pipe is sequentially subjected to four operations: sandblasting and rust removal, angle grinder polishing, sandpaper polishing and inner wall preheating;

[0056] Step 2. Debugging of spraying equipment:

[0057] Assemble the air compressor, pressure paint tank and long rod spray gun, and adjust the pressure of the pressure paint tank to 0.4MPa;

[0058] Ste...

Embodiment 3

[0065] The spraying process for the inner wall of the metal pipe of this embodiment includes the following steps:

[0066] Step 1. Inner wall substrate treatment:

[0067] Prepare the metal pipe to be sprayed, and the inner diameter of the metal pipe is less than or equal to the diameter of the circular atomization surface of the long rod spray gun, and the inner wall of the metal pipe is sequentially subjected to four operations: sandblasting and rust removal, angle grinder polishing, sandpaper polishing and inner wall preheating ;

[0068] Step 2. Debugging of spraying equipment:

[0069] Assemble the air compressor, pressure paint tank and long rod spray gun, and adjust the pressure of the pressure paint tank to 0.4MPa;

[0070] Step 3. Long rod spray gun positioning:

[0071] Prepare the spraying bracket of the long-barrel spray gun, insert the barrel of the long-barrel spray gun into the barrel sleeve 2, adjust the depth of the lower end of the support rod 3 into the connecting sle...

Abstract

The invention discloses a long-rod spray gun spraying bracket and a metal pipeline inner wall spraying technology, and belongs to the technical field of coating spraying. The long-rod spray gun spraying bracket comprises a bearing, a gun rod sleeve, a support rod and a base, wherein the bearing is fixed at the upper end of the support rod; the gun rod sleeve is fixed on the inner ring of the bearing; the central axis of the gun rod sleeve is parallel to that of the bearing; the lower end of the support is fixed on the base. The metal pipeline inner wall spraying technology comprises the following steps: (1) inner wall base material treatment; (2) spraying equipment debugging; (3) long rod spray gun positioning; (4) coating spraying; (5) coating firing. According to the invention, the main aim for one-time uniform spraying of the inner walls of metal pipelines with big pipe diameter is achieved, and the quality of fired coatings on the inner walls of metal pipelines is improved.

Description

Technical field [0001] The present invention relates to the technical field of paint spraying, and more specifically, to a spraying support of a long rod spray gun. Background technique [0002] Metal pipes are tools for conveying liquids or gases and are widely used in various fields of the national economy. In the process of use, the inner wall of the metal pipeline will inevitably have problems such as scaling and corrosion, which will affect the transportation of the working fluid in the metal pipeline and reduce the service life of the pipeline. Therefore, the protection of the inner wall of the metal pipeline is particularly important. At present, for the protection of the inner wall of metal pipelines, the usual method is to apply anti-corrosion and non-stick coatings on the inner wall of the pipeline, and the anti-corrosion and non-stick coatings on the inner wall of the pipeline have the advantages of low cost, easy realization and good adhesion. However, The existing s...
