Arm cylinder: above the bucket rod is connected with a shorter and wider cylinder, called the bucket arm cylinder, which provides strength for the bucket arm to move up and down, and then drive the bucket to grab or lift operation.
According to the structure of the hydraulic cylinder, it can be divided into four categories: piston cylinder, plunger cylinder, swing cylinder and special cylinder. According to the rated pressure is divided into high pressure and ultra-high pressure hydraulic cylinder, high pressure hydraulic cylinder and low pressure hydraulic cylinder…… .
The main parameters of the hydraulic cylinder include pressure, flow, size, piston stroke, movement speed, pushing force, efficiency and hydraulic cylinder power.
Hydraulic cylinder as a component, a working device, like all mechanical equipment, in the long-term operation process will inevitably produce different degrees of wear, fatigue, corrosion, loosening, aging deterioration and even damage in its structural components, making the hydraulic cylinder performance, technical conditions deteriorate, and then directly cause the whole hydraulic equipment failure, or even failure. Therefore, the elimination and maintenance of common problems in the daily work of the hydraulic cylinder is very important.
