The leakage at the wheel cover seal and interstage seal belongs to internal leakage. Serious internal leakage will increase the energy loss of the compressor, reduce the stage efficiency and compressor efficiency, and reduce the air displacement. However, the influence mechanism of the two is also different: the leakage of the wheel cover seal is to make the compressed gas return to the impeller, and then conduct the second stage compression, which mainly increases the total energy consumption of the stage; The leakage of interstage seal is interstage gas channeling, which will increase the low pressure stage ratio and decrease the high pressure stage ratio.
Although the serious leakage of the balance plate seal has little impact on the performance of the compressor, it has a great impact on the safe operation of the centrifugal compressor.
The leakage of shaft seal belongs to external leakage. External leakage refers to the leakage of gas from the seal to the outside of the casing. It goes without saying that serious leakage will directly reduce the discharge of the compressor.
Kaifeng DEAR Air Separation Industry Co., Ltd. adheres to the principle of technology as the guide and product quality as the principle. Through the establishment of municipal and provincial engineering technology research centers successively, relying on strong technical strength and equipment advantages, we actively seek strong alliances with colleges and universities, scientific research institutions, and advanced enterprises at home and abroad to jointly start the research and development of new technologies, new processes, and new products, create one or more high value-added end products, enter the high-level competitive field, and gradually transform into the company's main products.
