What is the suitability of the dual guide rod cylinder in high or low temperature environment?
2023-04-03Double rod cylinder is a common pneumatic transmission component, widely used in various automatic production lines and mechanical equipment. When using a double lead rod cylinder, it is necessary to consider its applicable temperature range, because the working environment at different temperatures will have different effects on the performance and life of the cylinder. In this paper, we will discuss the material, seal, lubricant and structure of the double rod cylinder in the high or low temperature environment.
First, the applicability of the double rod cylinder in the high temperature environment
In the high temperature environment, the use of double rod cylinder is limited, mainly because the high temperature will have a negative impact on the sealing performance, lubrication performance and material properties of the cylinder. For example, the high temperature cylinder seals are prone to aging, hardening, deformation and other phenomena, leading to gas leakage in the cylinder, reducing the efficiency and stability of the cylinder. At the same time, the high temperature will make the cylinder lubricant failure, increase the cylinder friction resistance and wear degree, affecting the service life of the cylinder. In addition, high temperature will affect the cylinder material strength, hardness and corrosion resistance, accelerating the aging and damage of the cylinder.
In order to adapt to the work requirements of high temperature environment, double guide rod cylinder need to use special materials and structural design. For example, the cylinder material can choose high-temperature alloy, ceramic and other high-temperature materials, seals can use high-temperature rubber, polyimide and other heat-resistant materials, lubricants can use high-temperature lubricants, grease and other high-temperature lubricants. In addition, the cylinder structure can be designed for internal cooling or external cooling type, through the cylinder coolant or external cooling equipment, reduce the internal temperature of the cylinder to extend the service life of the cylinder.
Second, the applicability of the dual guide rod cylinder in low temperature environment
In the low temperature environment, the use of dual guide rod cylinder is also limited, mainly because the low temperature will affect the sealing performance, lubrication performance and material properties of the cylinder. For example, the seal inside the cylinder may become hard or brittle in low temperature environment, leading to gas leakage inside the cylinder and reducing the efficiency and stability of the cylinder. At the same time, the viscosity of the lubricant will increase and the lubrication performance will decrease in low temperature, which will increase the frictional resistance of the cylinder and increase the risk of wear and damage of the cylinder. In addition, low temperature will affect the strength, toughness and corrosion resistance of the cylinder material, accelerating the aging and damage of the cylinder.
In order to adapt to the working requirements of low temperature environment, the dual guide rod cylinder needs to use special materials and structural design. For example, the cylinder material can choose low-temperature alloy, stainless steel and other low-temperature materials, seals can use low-temperature rubber, fluorine rubber and other low-temperature materials, lubricants can use low-temperature lubricants, grease and other low-temperature lubricants. In addition, the cylinder structure can be designed for internal heating type or external heating type, through heating equipment or cylinder heating elements, increase the internal temperature of the cylinder to ensure the normal work of the cylinder.
The suitability of the double lead cylinder in high or low temperature environment is closely related to its material, seal, lubricant and structure. In the actual application, it is necessary to choose the suitable double lead cylinder according to the specific working conditions and requirements, and take corresponding protective measures to ensure the normal work of the cylinder and prolong its service life.
