The mechanical seal DFB80-80-240H is a high-performance single-end face, single-spring mechanical seal. It is designed for cooling water pumps in power plants and can effectively prevent leakage of cooling water under high pressure and high temperature conditions. The seal has a compact structure, is easy to install, and can maintain long-term stable operation under harsh working conditions.

The core of the mechanical seal DFB80-80-240H lies in the design of its sealing end face. DFB80-80-240H uses a pair of precision-machined sealing rings, one of which is fixed to the pump housing and the other rotates with the pump shaft. A tiny gap is formed between the two sealing rings, which are kept in close contact by spring and hydraulic force. During operation, the cooling water forms a thin lubricating film between the sealing rings, which can prevent water leakage and reduce wear between the sealing rings.

When installing the DFB80-80-240H mechanical seal, it is necessary to strictly follow the operating procedures. First, ensure that the radial and axial runout of the pump shaft are within the allowable range, not exceeding 0.04mm and 0.1mm respectively. During the installation process, avoid knocking on the sealing components to ensure the integrity of the sealing end face. After the installation is completed, it is necessary to manually push the dynamic ring to check its flexibility and ensure that the shaft rotates without a sense of stagnation.

In daily operation, it is necessary to regularly check the leakage of the seal. Although mechanical seals rarely leak during normal operation, trace leakage is inevitable. If an increase in leakage is found, the wear of the sealing ring should be checked in time, and necessary maintenance or replacement should be carried out.

The mechanical seal DFB80-80-240H has been widely used in cooling water pumps in multiple power plants. For example, in a 600MW generator set, the seal successfully prevented the leakage of cooling water and improved the operating efficiency and reliability of the system. By using this high-performance mechanical seal, the power plant not only reduced the waste of cooling water, but also reduced the maintenance cost and downtime of the equipment.

Mechanical seal DFB80-80-240H has become an ideal choice for cooling water pumps in power plants with its excellent sealing performance, reliability and economy. It can not only effectively prevent cooling water leakage, but also maintain stable performance during long-term operation. For modern power plants that pursue high efficiency, energy saving and environmental protection, DFB80-80-240H is undoubtedly a trustworthy partner.
