Cylinder is a key component in construction machinery, its function is to convert the pressure of hydraulic oil into mechanical motion. Cylinder controls the movement of the arm, bucket, shovel and other components of the machine by controlling the entry and exit of hydraulic oil. When the hydraulic oil enters from the cylinder at one end, the hydraulic oil at the other end will be discharged to realize the movement of the mechanical parts.
Classification of excavator cylinder:
There are many classification methods for excavator cylinders. According to the working principle, it can be divided into single-acting cylinder and double-acting cylinder.
According to the installation method, it can be divided into built-in oil cylinder and external oil cylinder. According to the material, it can be divided into cast iron cylinder and forged steel cylinder. According to the use environment, it can be divided into ordinary oil cylinder and explosion-proof oil cylinder. Different types of oil cylinders need to pay attention to their characteristics and use environment when using them.
Excavator oil cylinder maintenance:
Excavator cylinders also need to be maintained during usage to ensure their normal service life. For built-in cylinders, it is necessary to regularly check the sealing ring, surface condition of the piston rod, and regularly drain water and dirt. For external oil cylinders, it is necessary to check whether the oil pipes and joints are leaking, check whether the oil seal is damaged, and regularly add lubricating oil.
