What common faults should be avoided when using construction machinery cylinders?

The construction machinery cylinder is a common hydraulic component widely used in construction machinery. Its main function is to convert hydraulic energy into mechanical energy for the movement of various construction machinery. However, during use, the construction machinery cylinder will also encounter some common faults. To ensure the normal operation of the construction machinery and extend the service life of the cylinder, we need to prevent the following common faults: leakage, internal corrosion, hydraulic oil contamination, cylinder collision, etc.
First of all, leakage is one of the common faults of construction machinery cylinders. The phenomenon of leakage is generally manifested as hydraulic oil leakage when the cylinder is working. There are many reasons for leakage, such as aging of seals, wear of sealing surfaces, overload of hydraulic systems, etc. To prevent this kind of fault, we need to regularly check and replace the seals of the cylinder to ensure its service life and sealing performance. Secondly, try to avoid overloading and frequent starting and stopping at work, to reduce the pressure and impact of the hydraulic system and reduce the risk of leakage.
Secondly, internal corrosion of the cylinder is also a common fault. Internal corrosion of the cylinder is mainly caused by impurities and moisture in the hydraulic oil. When corrosion occurs inside the cylinder, it will seriously affect its working performance and service life. Therefore, we need to check and replace the hydraulic oil frequently and ensure that it is clean and free of moisture. In addition, during use, we should also pay attention to keeping the inside of the cylinder dry and clean to avoid impurities and moisture from entering.
Third, hydraulic oil contamination is also a common fault that needs to be prevented. Hydraulic oil contamination mainly comes from dust, impurities, and other particles in the external environment and metal particles, rubber crumbs and other impurities inside the cylinder. These pollutants will seriously affect the working performance and service life of the cylinder. Therefore, we need to regularly replace and filter the hydraulic oil to ensure that it is clean and free of impurities. In addition, we should also pay attention to keeping the working environment clean during work to avoid dust and impurities from entering the hydraulic system.
Finally, cylinder collision is also a common fault that needs to be prevented. Cylinder collision is generally caused by the sudden stop of the piston of the hydraulic cylinder when the workload suddenly decreases or stops. This collision will cause the internal pressure of the cylinder to increase suddenly, causing vibration and damage to the cylinder. To avoid cylinder collision, we need to reasonably design and select the cylinder and hydraulic system to ensure that its workload and pressure match the movement requirements. Secondly, sudden stops or load reduction should be avoided during work. The load can be reduced slowly to reduce the risk of collision.
In summary, construction machinery cylinders will encounter some common faults during use, including leakage, internal corrosion, hydraulic oil contamination, and cylinder collision. In order to prevent these faults, we need to regularly check and replace the seals of the cylinders, keep the hydraulic oil clean and dry, design and select models that meet work requirements, and avoid overloading and frequent starting and stopping during work. Only by doing this can we ensure the normal operation of construction machinery cylinders and extend their service life.
