What factors should be considered in the design of sealing structure of construction hydraulic cylinders?

In hydraulic systems, the design of sealing structures is a key factor in ensuring system reliability and efficiency. Jiangsu Hengcai takes into account the working environment, load conditions, sealing materials and forms, matching accuracy and installation quality in the design of hydraulic cylinder sealing structures.

Working environment and load conditions
The working environment and load conditions of hydraulic cylinders are the primary considerations for the design of sealing structures. Different environmental factors, such as temperature, humidity and chemical corrosion, will directly affect the selection of sealing materials and sealing performance. Under extreme temperature conditions, the sealing materials of hydraulic cylinders must have good high and low temperature resistance to prevent material aging or performance degradation due to temperature changes. In addition, the type, size and direction of loads borne by hydraulic cylinders also put forward higher requirements for the design of sealing structures. For example, heavy-duty hydraulic cylinders require the use of stronger sealing materials and the design of more robust sealing structures to ensure that the sealing performance remains stable under high pressure and heavy load working conditions to avoid leakage.

Sealing materials and sealing forms
The selection of sealing materials and the design of sealing forms are the core of the sealing structure. In the process of selecting sealing materials, Jiangsu Hengcai fully considers various performance indicators such as wear resistance, corrosion resistance, high temperature resistance and elasticity of the materials to ensure that the selected materials can play the best effect under different working environments and load conditions. According to the specific application requirements of the hydraulic cylinder, we will choose the appropriate sealing form, such as lip seal, piston ring seal and combined seal. Each sealing form has its unique advantages and scope of application. Through reasonable material selection and sealing form design, the sealing performance can be maximized and the overall efficiency and reliability of the hydraulic cylinder can be improved.

The matching accuracy and installation quality of the seal
The influence of the matching accuracy and installation quality of the seal on the sealing performance cannot be ignored. In the design of the sealing structure, Jiangsu Hengcai pays special attention to the matching accuracy between the seal and the cylinder barrel, piston rod and other components. Through precise processing technology and strict measurement standards, we ensure that the matching clearance between the components is in the best state, thereby effectively improving the sealing effect. In addition, we also provide customers with detailed installation guides and professional training to ensure that customers can correctly install and debug the hydraulic cylinder to avoid leakage problems caused by improper installation.
