1. Application scenarios of seals in mechanical equipment
Hydraulic pumps, hydraulic motors and actuators: In these hydraulic components, seals are used to prevent hydraulic oil leakage and ensure the normal operation of the hydraulic system. Common seals include O-rings, Y-rings and oil seals.
Valves and filters: Valves and filters are common fluid control components in mechanical equipment. Seals are used to ensure the sealing performance of these components and prevent fluid leakage.
Rotating shafts and bearings: In the rotating parts of mechanical equipment, such as rotating shafts and bearings, seals are used to prevent lubricating oil leakage and external impurities from intruding. Common seals include rotating shaft seals and bearing seals.
Pistons and cylinders: In the piston and cylinder parts of mechanical equipment, seals are used to ensure the sealing performance between the piston and the cylinder to prevent gas or liquid leakage. Common seals include piston seals and cylinder seals.
2. The important role of seals in mechanical equipment
Prevent leakage: The main function of seals is to prevent the leakage of liquid or gas in the equipment and ensure the normal operation and safety of the equipment.
Prevent contamination: In some harsh environments, such as medical equipment or food processing equipment, seals can prevent contaminants from entering the equipment and ensure product quality and safety.
Resistant to high temperature and high pressure: In some industries, such as aviation and aerospace, seals that can withstand high temperature and high pressure are required to ensure the normal operation of equipment in extreme environments.
Reducing friction and wear: Seals can form a protective coating between metals and other hard materials, thereby reducing friction and wear and extending the service life of the equipment.
3. Precautions for the selection and installation of seals
Choose the right seal: When selecting seals, you need to consider factors such as the type of fluid used in the system, the maximum temperature of the system under working conditions, and the expected functional reliability. At the same time, you also need to choose the right material and model according to the application scenario and performance requirements of the seal.
Correctly install the seal: The installation process of the seal needs to follow certain specifications and precautions, such as maintaining cleanliness and protecting the seal from scratches and cuts. Correct installation can ensure the sealing performance and service life of the seal.
In summary, the application of seals in mechanical equipment is crucial. They not only prevent leakage and contamination, but also resist high temperature and high pressure, and reduce friction and wear. When selecting and installing seals, it is necessary to fully consider the application scenarios and performance requirements to ensure the correctness and reliability of the seals.
