Hydrogen side oil return control box
The hydrogen side oil return control box adopts the imported technology of Westinghouse Company of the United States as a key development and production technology research project in Shanghai in the early 1990s, and passed the municipal appraisal. The actual use of the user proves that the equipment has reached the advanced level of similar products in China. At present, the equipment has been selected by many overseas manufacturers such as Shanghai Waigao Power Plant, Wujing Thermal Power Plant, Maanshan Power Plant, Hubei Hanchuan Power Plant, Shandong Heze Power Plant, and Iran Sahand Power Plant.
Product Details
The hydrogen side oil return control box is one of the key components in the large-scale hydrogen-cooled generator sealing oil system of 300MW, 600MW, etc. It is the key to provide sealing oil source to the sealing tile to prevent the hydrogen in the generator from escaping outside the rotating shaft. Features. When the equipment is in operation, the supply and discharge valves automatically adjust the oil level in the tank to control it within a certain range to ensure that the sealing oil system can work normally. When the oil level is too low, the alarm sends an alarm signal to the control system. If the supply and drain valves fail, the valve can be manually opened or closed.
