The medium used in the oil supply system of the steam turbine is phosphate ester fire-resistant oil. Due to its unique chemical properties, the components such as oil pumps, valves, and filter elements in the system need to be made of suitable materials to be suitable for high-temperature and high-pressure fire-resistant oil systems. Among them, the pump shaft seal TCM589332 of the fire-resistant main oil pump is also a product specially designed and manufactured for steam turbines, which has the following characteristics to meet the requirements of steam turbine operation.

The skeleton oil seal TCM589332 has good corrosion resistance. EH fire-resistant oil has certain corrosiveness, especially to certain metal materials. Therefore, the oil seal adopts a material that can withstand EH oil corrosion to avoid material damage and leakage.

The skeleton oil seal TCM589332 can maintain stability and sealing performance under high temperature conditions, as the use of turbine resistant oil in high-temperature and high-pressure environments requires high temperature resistance of the oil seal. Excellent temperature resistance can ensure the sealing effectiveness of the skeleton oil seal.

The elasticity and compression deformation ability of the TCM589332 material for the skeleton oil seal can also ensure stable sealing. It can effectively prevent the leakage of phosphate ester fire-resistant oil in high pressure environments.

In addition, due to the certain lubricity of phosphate ester fire-resistant oil, it can reduce the friction and wear between the skeleton oil seal and the rotating shaft. The skeleton oil seal TCM589332 also needs to have certain lubrication performance to achieve lower friction and wear.
