What are the steps to repair the wear and tear of the salt mud pump?

The salt mud pump is an important brine conveying equipment in the chlor-alkali industry.
It is not only of high value, but also damaged frequently.
Due to the difference in pump application environment and conveying medium, problems such as corrosion, cavitation, and abrasion often occur in the impeller, pump casing, and guard plate.
Although the structure of the pump body is simple, the pump is also a scientific and precise device.
The assembly dimensions between the components are very strict.
Once corrosion, cavitation, and abrasion occur, the overall pump efficiency of the pump will decrease and the consumption of com" href="">paint online coatingol.
com will increase .

XK acid and alkali resistant and wear-resistant coating is a solvent-free high-performance two-component epoxy composite material.
The material is composed of high-performance epoxy resin, carbon fiber, silicon steel, ceramics, etc.
The material has good adhesion, impact resistance, erosion resistance, corrosion resistance and other properties, and it can adhere to various metals, concrete, glass and other materials.

Application scope: repair and protect various equipment under high abrasion, cavitation and impact environments in high temperature environments, such as desulfurization pumps, slurry pumps, mud pumps, pulp pumps, sewage pumps and other pumps, as well as coal crushers and chutes , Fans, pulverized coal scales, coal mills, pipelines, coal processing tanks, valves, etc.

Salt mud pump repair plan one, surface treatment

1.

Use a high-pressure water gun or steam to flush the deposits inside the equipment.

2.

Use oxyacetylene flame to remove moisture and oil.

3.

Use the electrode of the corresponding material to repair the worn part of the volute.

4.

The surface is sandblasted to remove rust to a metallic luster.

2.

Repair process

1.
Mix the components A and B of XK-YHL-J-2.
0-3.
0RJ acid and alkali resistant and wear-resistant coating at a ratio of 40:1 by weight and stir evenly.
Use the heated coating tool to coat the equipment special repair agent on Wear parts of the equipment, apply in one direction.

2.
Mix the components A and B of XK-YHL-J-1.
0-2.
0RJ acid and alkali resistant and wear-resistant coating at a ratio of 40:1 by weight, mix and stir them, and use the heated coating tool to evenly coat the equipment special repair agent On the surface of the workpiece, use a scraper to make the surface of the coated material smooth and smooth.

3.

After the initial solidification, mix the equipment-specific repair finish evenly in proportion, and coat it on the surface of the workpiece with a batch knife for surface treatment to make the repair surface smooth and smooth.

4.

Heating and curing: After initial curing, place the workpiece in a heating furnace and heat it to 120°C, timing for 3 hours to achieve complete curing.

XK acid and alkali resistant and wear-resistant coatings have good cavitation resistance.

Generally, pumps will improve the performance and hardness of metal materials in order to solve the problem of cavitation resistance, which often increases the construction cost and reduces competitiveness.
