Introduction
Metric O-ring kits are a seal set consisting of an O-ring and support ring, mainly used for reciprocating motion sealing in hydraulic systems.
The O-ring kit is an important part of the hydraulic system. Its function is to ensure that the system's hydraulic fluid does not leak under high-pressure and high-speed working environments, thereby maintaining the efficient and stable operation of the system.
Sealing principle
The working principle of the metric O-ring kits mainly relies on the elastic deformation of the O-ring and the fixing effect of the support ring. When the hydraulic system applies pressure, the O-ring is squeezed and elastically deforms, filling in the microscopic unevenness on the sealing surface, thereby forming an effective seal. At the same time, the support ring ensures the stable position of the O-ring under high pressure and prevents it from being extruded or falling off.
Application scenarios
1. Hydraulic system: Metric O-ring kits are used in hydraulic systems, such as machine tools, ships, automobiles, aerospace equipment, metallurgical machinery, chemical machinery, engineering machinery, construction machinery, mining machinery, petroleum machinery, etc. In these systems, O-ring kits are used to seal the hydraulic fluid to ensure efficient and stable operation of the system.
2. Pneumatic system: In pneumatic systems, O-ring kits are used to seal the flow of gas or air and prevent it from leaking. These systems often rely on fluid transfer under pressure, so the sealing action of the O-ring kit is critical to maintaining system efficiency.
3. Automotive industry: In the automotive industry, O-ring kits are widely used for sealing various components such as engine blocks, transmission systems, fuel injectors, and braking systems. They can also be used to seal air conditioning and cooling systems to prevent refrigerant leaks.
4. Aerospace industry: In the aerospace industry, metric O-rings are used to seal fuel tanks, hydraulic systems, and other key components. They can also be used to build spacecraft, satellites, and other space exploration equipment.
5. Medical industry: In the medical industry, O-ring kits are used to seal medical equipment and devices, syringes, and other medical supplies. They can also be used in prosthetic devices and surgical implants.
6. Chemical Industry: In the chemical industry, metric O-ring kits are used to seal pumps, valves, pipes, and other equipment used in chemical manufacturing and processing. Since these devices are often exposed to a variety of chemicals, O-ring kits need to be chemically resistant.
