The AC sealing oil pump DLZB820-R64 is a pump type specifically designed for generator sealing oil systems, with one installed on the air side and one on the hydrogen side. The unique design of this oil pump allows for the adjustment of the oil pressure at the outlet of the pump while ensuring its operational efficiency. When the hydrogen pressure is less than 0.16MPa, the sealed oil tank will use the oil discharge from the hydrogen side oil pump outlet.

During operation, the sound of the AC sealing oil pump DLZB820-R64 is normal, and the vibration amplitude is also controlled within the specified range. Among them, the vibration amplitude of the air side sealing oil pump is less than 0.05mm, and the vibration amplitude of the hydrogen side sealing oil pump is less than 0.10mm. This operating state not only ensures the normal operation of the oil pump, but also reduces the failure rate and improves its service life.

It is worth mentioning that the AC sealing oil pump DLZB820-R64 can be shut down for a short period of time during maintenance. This provides great convenience for maintenance and repair, saving labor and material costs.

However, when the hydrogen side pump stops running, the flow of sealing oil from the air side to the hydrogen side will greatly increase, which will lead to an increase in air infiltration inside the generator. To solve this problem, a certain amount of hydrogen gas is absorbed by the oil and carried by the generator. This design ensures the normal operation of the generator while avoiding hydrogen leakage, ensuring the safety of the generator.

Overall, the AC sealing oil pump DLZB820-R64 plays a crucial role in the sealing oil system of the generator. Its reasonable design, stable operation, and convenient maintenance provide strong guarantees for the normal operation of the generator. In the future, with the continuous development of China’s power industry, the market demand for DLZB820-R64 sealed oil pumps will be increasing. Its excellent performance and stability make it the best choice for generator sealing oil systems.
