Interpretation of the inner wall of the bottom cylinder

During the working process of the bottom cylinder of the hydraulic support, hard particles such as coal dust are easily accumulated on the mating surface with the column, causing scratches, and the hydraulic oil is easily mixed with corrosive media such as moisture and H2S, resulting in rust on the inner surface of the bottom cylinder. Affecting the sealing effect and reducing the lifting force, the variable pressure cold metal fusion welding technology developed by Aigang effectively solved this problem.

What is the remanufacturing of the inner wall of the bottom tank?

The so-called wear-resistant and anti-corrosion remanufacturing of the inner wall of the bottom cylinder is to recover the scrapped or soon to be discarded bottom bracket of the hydraulic support, and use the independently developed variable pressure cold metal fusion welding technology and equipment to carry out a professional and batch production process. To restore the performance of the damaged bottom cylinder.

The new technology of wear-resistant and anti-corrosion remanufacturing of the inner wall of the bottom bracket of the hydraulic support created by Aigang has the advantages of high degree of automation, low cost, wear resistance, and significant anti-corrosion effects. Call.

How to remanufacture the inner wall of the bottom cylinder for abrasion and corrosion resistance?

Bottom cylinder inner wall variable flow pressure cold metal welding wear-resistant, anti-corrosion remanufacturing enhanced repair process: bottom cylinder condition assessment → attachment removal and rust removal and decontamination → machining positioning surface processing → cylinder inner wall rust layer boring → cylinder inner wall change Flow pressure cold metal fusion welding → Cylinder inner wall cladding machining → Exterior wall attachment installation, painting and delivery

Why choose Aigang Remanufacturing?

Advantage
With many years of cold metal fusion technology research and development experience and mature remanufacturing process, we have developed special equipment for wear-resistant and anti-corrosion remanufacturing of the inner wall of the bottom cylinder;
Have experience in repairing and strengthening the inner wall of the bottom cylinder of the hydraulic support of different models, and can quickly formulate repair and reinforcement plans for the bottom cylinders of different models and different degrees of damage to restore the performance of the bottom cylinder;
Adopting CNC system, with high degree of automation and high production efficiency, it takes about 4 hours to process one square meter of inner wall;
Under the same working conditions: the inner wall of the bottom cylinder strengthened and repaired has greatly improved abrasion resistance and corrosion resistance. The Brinell hardness (HB) of the cold-melted copper alloy is about 280, which breaks through the existing HB hardness of 120-140. Hovering status quo, the service life of more than twice the new products;
Has multiple professional bottom cylinder inner wall repair and remanufacturing teams, 100% guarantee of project quality and construction period;
breakthrough

In 2015, Aigang remanufactured the bottom cylinder of ZY10000 / 28 / 62D (φ260 * 1850) hydraulic support for a certain mine of Shenhua Ning Coal Group.

In November 2016, our company undertook the copper melting business of the inner wall of Zhengmei's hydraulic support bottom cylinder (Φ530 * 2463mm).

In March 2017, six internal wall surfacing welders cold-melted copper the inner wall of the hydraulic support bottom cylinder (530 * 2118mm) in the North Coal Machine Workshop.
