Hydraulic cylinders are an important component of excavators, as they provide an efficient means of converting the energy from hydraulic fluid into powerful, reliable motion. In this article, we will explore the mechanisms and principles of excavator hydraulic cylinders, as well as the advantages and disadvantages of using them. We will also discuss the importance of understanding these mechanisms and principles before using excavator hydraulic cylinders.
Spare Parts From Excavators Cylinders
Pistion of hydraulic cylinder
A piston of an excavator cylinder is a cylindrical device that moves in a reciprocating manner within the cylinder of the excavator. It is connected to the crankshaft and is used to convert the rotational motion of the crankshaft into a linear motion that can be used to power the excavator’s bucket. The piston is typically made of steel and is fitted with a series of rings that create a seal between the cylinder and the piston.
Hydraulic cylinder barrel
The cylinder barrel is the container of all cylinder components, but more importantly, it will contain all cylinder pressures. In heavy construction equipment, the pressure may be very high, which requires special design of the barrel to operate at high internal pressure for a long time. The internal mechanism and components of the cylinder are designed to work within a specific range, so the barrel also plays a role in resisting external factors and forces. Rain, dust and impact – the barrel must be designed to resist internal and external forces.
Piston rod from cylinder of excavators
The piston rod is connected to the piston with different length. The connecting rod retracts and extends inside and outside the cylinder barrel and is directly connected to the component that the operator is moving.
During the push-pull process, the piston rod must leave the piston barrel and then the hydraulic oil tank. Just like a turtle sticking its neck out of its shell, when the piston rod is exposed to the atmosphere, it will face new risks. In this case, it will be affected by erosion, impact, lateral force, and even the weather. The length of the piston rod determines the extension distance of the cylinder, which is called the stroke. The piston rod needs to be manufactured to maintain the load, even if the piston rod is fully extended. Think about it. Compared with the case of arm extension, hold the chest with a heavy object namely Big cylinder for Heavy-duty machines.
Excavator cylinder’ s O-Rings and Seals
O-Rings and seals are an important part of excavator cylinder. O-rings are used to create a seal between the two parts of the cylinder so that fluid cannot escape. Seals are used to prevent dust, dirt, and other contaminants from entering the cylinder. Both O-rings and seals should be inspected regularly to ensure that they are in good condition and not worn or damaged. If O-rings or seals are found to be damaged, they should be replaced immediately.
