What Are Hydraulic Cylinders?

Hydraulic cylinders are an important part of the hydraulic system, which is used in many industries to transmit power. The hydraulic cylinder is composed of a piston, a piston rod, a cylinder and a cylinder head. The cylinder head is sealed by a cylinder head seal, and the piston is sealed by a piston seal. Seals are essential for the normal operation of the hydraulic cylinder.

Classification Of Seals

Seals for hydraulic cylinders are mainly divided into two categories: static seals and dynamic seals. Static seals are mainly used for sealing the gap between the piston and cylinder wall, and dynamic seals are mainly used for sealing the gap between the piston rod and piston.

Advantages Of Seals

• Good sealing performance, no leakage;
• Good wear resistance;
• Excellent oil resistance and chemical resistance;
• Good self-lubricating performance;
• Low friction coefficient and long service life.

Installation Of Seals In Hydraulic Cylinder

When installing the seals of the hydraulic cylinder, the installation should be done in strict accordance with the installation instructions and the installation requirements. Generally, the installation is completed in the following steps:

• Choose the right seal for the cylinder;
• Clean the surface of the cylinder;
• Install the seal into the piston or the piston rod;
• Install the seal onto the cylinder wall;
• Install the piston into the cylinder;
• Install the piston rod into the cylinder.

How To Replace Seals In Hydraulic Cylinder

When replacing the seals of the hydraulic cylinder, you should first determine the type of seal you need, then clean the cylinder surface, and then remove the old seal from the piston or the cylinder wall. After the new seal is installed, the new seal should be lubricated with oil.

How To Choose The Right Hydraulic Oil And Oil Seal

When selecting hydraulic oil and oil seals, you should pay attention to the following points:

• Choose the right type of hydraulic oil according to the requirements of the equipment;
• Choose the right type of oil seal according to the operating conditions;
• Pay attention to the operating temperature of the oil seal.

When To Replace The Seals In Hydraulic Cylinder

When the seal of the hydraulic cylinder is damaged or worn, it needs to be replaced. Generally speaking, you need to replace the seals when the following situations arise:

• Leakage of oil from the cylinder;
• Squeaking sound during operation;
• Damage on the surface of the seal;
• The seal is seriously worn.

How To Choose A Suitable Power Unit?

When selecting a power unit for a hydraulic cylinder, you should consider the following factors:

• The power of the power unit should be greater than the power of the hydraulic cylinder;
• The operating pressure of the power unit should be greater than the operating pressure of the hydraulic cylinder;
• The operating temperature of the power unit should be greater than the operating temperature of the hydraulic cylinder;
• The type of oil used by the power unit should be compatible with the type of oil used by the hydraulic cylinder.
