Cylinder;Chock(R.H)

The main function of the excavator wedge oil cylinder – right is to control the excavator’s boom movements.

The working principle of an excavator relies on the hydraulic system, especially the application of hydraulic cylinders. Hydraulic cylinders convert hydraulic energy into mechanical energy to achieve linear reciprocating or swinging motion. In an excavator, the wedge oil cylinder – right (or similar components such as the boom cylinder) is an important part of the excavator’s working mechanism, responsible for controlling the boom’s lifting, extension, and other movements. These actions depend on the internal structure and working principles of the hydraulic cylinder.

The basic components of a hydraulic cylinder include the cylinder barrel and end cap, piston and piston rod, sealing device, cushioning device, and exhaust device. The effective area of the piston and the pressure difference on both sides determine the output force of the hydraulic cylinder, enabling various movements of the excavator. For example, the boom movement of the excavator is achieved by controlling the piston position in the hydraulic cylinder, thereby controlling the lifting and extension of the boom to complete tasks such as digging and loading.

Furthermore, the design of the excavator’s cylinders considers the practical application requirements. For instance, the boom of an excavator has significant weight, so the cylinder design needs to withstand this weight. Double-acting cylinders (such as the hydraulic boom cylinder, arm cylinder, and bucket cylinder) generate force by multiplying the projected area of the piston rod cavity by the oil pressure, with the force in the rodless cavity far greater than in the rod cavity. This design helps improve work efficiency and operational stability.

In conclusion, the main function of the excavator wedge oil cylinder – right is to control the piston position in the hydraulic cylinder, enabling movements such as lifting and extension of the boom to accomplish various tasks of the excavator.
