The metal briquetting machine has a wide range of uses. In addition to pressing metal shavings, it can also be used for pressing other plastic materials and stretching, packing, pressing, and correcting other materials. In the process of using the metal briquetting machine, we will encounter many problems, not because of the quality of the equipment, but because of its high technical and environmental requirements. Take the high oil temperature as an example. Basically every model of metal briquetting machine will appear, but many people don't know what to do. Let's introduce the hazards, causes and solutions.
The hazards of high oil temperature of metal briquette
1. Excessive oil temperature will accelerate the aging and deformation of the oil cylinder sealing ring, dust seal and O-ring, which will cause oil leakage in the equipment and wear the piston rod. If it is not solved in time, the oil cylinder will be scrapped;
2. The viscosity of hydraulic oil decreases, the oil film of moving parts such as hydraulic valves becomes thinner and cut, and the frictional resistance increases, resulting in increased wear;
3. Too high oil temperature will accelerate the oxidation of the oil, cause the oil to deteriorate and reduce the service life of the oil. The asphalt and other sediments that precipitate in the oil will also block the small holes and gaps of the components, which will affect the normal operation of the system.
4. Excessive oil temperature will cause thermal deformation of mechanical components, and hydraulic valve components will expand after being heated, which may reduce the fit gap, thereby affecting the movement of the valve core, increasing wear, and even being stuck.
