1. The slide valve is scratched, worn and corroded. When the sharp edge of the shoulder is squeezed and rounded, it should be chrome-plated or replaced.
The use of chrome repair, should be worn before plating to about 0.2mm, 0.4-0.5mm plated chromium, and then according to the size of the valve body bore to the required size. All sharp edges shall not be chamfered unless required.
2. When there is a crack in the slide valve housing, it should be replaced.
3. Slider body hole wear, grinding repair.
The grinding rod is made of cast iron, which is softer than the valve body, for a minimum of two per set. Rough grinding rod with oil tank; polishing grinding rod with a smooth cylinder. The structure is simple and the size is easy to guarantee. The precision of the hole after grinding is higher, the roundness and the cylindricity are not greater than 0.005mm, and the surface roughness can reach less than 0.1μm. However, the efficiency is low, and the service life of the grinding rod is short.
Grinding rods than the length of the hole to be studied more than 100mm.
Grinding with M10 alumina grinding paste, lubricating the coolant is generally used 98% kerosene, 1% -2% oleic acid; also can be used in crude research with kerosene mixed with a small amount of mechanical oil; refined with petrol or gasoline mixed with kerosene.
Tungsten carbide pellets are small, cylindrical or spherical shapes made from tungsten carbide, a hard and dense material. These pellets are typically used in various industrial applications, such as drilling, grinding, cutting, and wear-resistant components.
Tungsten carbide is a compound of tungsten and carbon, known for its high hardness, strength, and resistance to wear and corrosion. It is often used as a cutting tool material, as well as in the production of mining and drilling equipment.
The pellets are usually produced through a process called powder metallurgy, where Tungsten Carbide Powder is mixed with a binder material and then compacted under high pressure. The compacted pellets are then sintered at high temperatures to form a solid and durable product.
Tungsten carbide pellets are used in various industries, including mining, construction, oil and gas, and manufacturing. They are commonly used as inserts in drilling bits, cutting tools, and wear-resistant parts, providing high performance and extended tool life.
Overall, tungsten carbide pellets are essential components in many industrial applications, offering superior hardness, strength, and wear resistance.
