In the steam turbine system, the HPU-V100A precision filter element is a key component for maintaining the quality of EH oil. Its function is to remove impurities and particles from the oil, ensuring the cleanliness of the oil system and the smooth operation of the steam turbine equipment. In this filtration process, the role of the filter element end cover should not be underestimated, as it plays a crucial role in the performance of the filter element and the integrity of the system.

Fixation and sealing: The main function of the HPU-V100A filter element end cover is to ensure that the filter element is firmly positioned in the oil circuit, while providing effective sealing to prevent oil leakage or bypassing the edge of the filter element. This tight fit avoids the infiltration of unfiltered oil and ensures the purity of the oil.

Under pressure: During the filtration process, the oil will generate pressure, and the end cover of the filter element must be able to withstand these pressures while maintaining its sealing performance without decreasing. This requires that the material and design of the end cap must be strong enough to adapt to the working pressure of the system and prevent any pressure leakage from occurring.

Structural strength: The end cover provides necessary structural support for the filter element, especially in the high-temperature and high-pressure environment of the steam turbine. This strength is crucial as it can prevent the filter element from deformation or damage due to mechanical stress.

Prevent media backflow: In some filter element designs, the end cap may include a one-way valve or other device that helps prevent filtered oil from flowing back through the filter element, thereby preventing unfiltered oil from flowing back into the system.

Material selection: The material of the end cap must be compatible with the filter element material and EH oil to prevent any chemical reactions or corrosion. In the EH oil station of a steam turbine, the oil may contain multiple chemical components, so the requirements for end cover materials are more stringent. Good corrosion resistance is the key to ensuring the long-term stable operation of the filter element.

It should be noted that improper end cover design or material selection of low-quality filters can affect the overall performance of the filter and the stability of the system. When selecting, attention should be paid to discrimination.
