Mechanical seal DLZB820R64B Chhabra power
Date:2025/3/20 8:39:32 Visits: Author:Dongfang YOYIK Engineering Co; Ltd,Mechanical seal DLZB820R64B is a high-performance sealing device for generator oil pump sealing. Its main function is to prevent lubricating oil from leaking into the external environment during the operation of the oil pump, while maintaining the closedness of the oil system. By preventing oil leakage, the mechanical seal helps to maintain the pressure stability of the oil system, thereby ensuring the safe and stable operation of the generator.
Performance characteristics
1. Reduce leakage: Mechanical seal DLZB820R64B can effectively reduce the internal leakage, external leakage and through leakage of the machine, and improve the volumetric efficiency of the machine.
2. Improve efficiency: Improve the mechanical efficiency of the machine by reducing friction loss.
3. Adapt to harsh working conditions: Mechanical seals can adapt to harsh working conditions such as high temperature, high pressure, high speed and corrosion, ensuring stable operation in various environments.
4. Long life: Mechanical seal DLZB820R64B has a long service life, generally can be used continuously for 1 to 2 years, special can reach 5 to 10 years or more.
5. Low power loss: Due to the small end contact area of the mechanical seal, the friction power loss is small, generally only 20% to 30% of the packing seal.
Application scenarios
1. Power plant: Mechanical seal DLZB820R64B is widely used in the generator sealing oil system of the power plant to ensure the normal operation of the sealing oil pump and prevent lubricating oil leakage.
2. Industrial automation: In the automated production line, it is used to control the sealing of various fluid media to achieve automation and precise control of the production process.
3. Other industrial fields: such as petrochemical, metallurgy and other industries, used in occasions requiring high-precision and high-reliability sealing.
Installation and maintenance
- Installation points: During installation, ensure that the cross-sectional direction of the sealing ring is correct to avoid sealing failure caused by reverse installation. At the same time, ensure that the installation site is clean and dry to prevent impurities from affecting the sealing effect.
- Maintenance suggestions: Regularly check the wear and aging of the sealing ring and replace it in time to ensure the sealing performance of the system. During maintenance, pay attention to the protection of key components such as the sealing ring to avoid damage caused by improper operation.
