The piston is determined according to the cylinder bore level of the garbage truck. The bore diameter of the cylinder is represented by numbers or letters and is generally located at the rear side of the cylinder. When using a new cylinder, check the bore level on the rear side of the cylinder and select the same piston level. When the cylinder is repeatedly used, the bore diameter is measured first, and the bore level is determined by comparing the measurement result with the bore diameter of the piston selection table. Finally select the same level of bore. Prior to installation, the piston rings should be carefully inspected and their models, specifications, and numbers should be checked. Piston rings and ring grooves should be kept clean. The rings should be painted with very little oil.
When installing the garbage truck piston ring by hand, place the piston ring flat on the piston ring expander seat and install the piston rings in sequence. At the same time, the marked side of the cylinder should face upwards. The opening positions of the rings should be staggered with each other so as to create a labyrinth passage to reduce the leakage of gas and oil. The position of the opening should be avoided in the direction of the piston pin and the direction of the lateral thrust. The assembly oil ring is generally installed by hand, and the opening portions of the scraper ring and the wiper ring spring cannot be on the axis of the piston pin. Adjust the pound code so that its two ends are balanced. The scale value corresponding to the pound code is the elastic force of the piston ring.
Tungsten carbide grits are small particles or granules of tungsten carbide, a compound made up of tungsten and carbon atoms. They are extremely hard and have a high resistance to wear and abrasion, making them useful in a variety of industrial applications.
Tungsten carbide grits are often used as abrasives in cutting tools, grinding wheels, and sandpaper. They can also be used as an additive in metal alloys to improve their hardness and wear resistance. Additionally, tungsten carbide grits are used in the mining and drilling industry for rock drilling and excavation.
These grits are available in different sizes and shapes, such as spherical or irregular particles, depending on the specific application. They are typically produced through a process called sintering, where Tungsten Carbide Powder is heated and compressed to form a solid material.
Overall, tungsten carbide grits are highly valued for their hardness, durability, and resistance to wear, making them essential in various industries where high-performance materials are required.
