The centrifuge is used in explosive or flammable applications in chemical industry, petrochemical industry, pharmacy industry and other industries, and any leakage of gas into the external atmosphere is prohibited in the course of solid-liquid separation, or used in solid-liquid separation in applications in which explosion may be caused if the external air enters the inner chamber of the centrifuge. Both ends of the bowl and the liquid outlet are airtight to achieve the airtight and flameproof effect.
Structure and principle of airtight seal
The gas-tight seal is a special structure consisting of the mechanical seal and inert gas supply device. It effectively prevents the external air from penetrating into the inner chamber of the centrifuge, and prevents the gas inside the centrifuge from leaking into the external environment.
The seal device consists of several seal rings and glands, and separates the inner chamber of the centrifuge from the surrounding environment. The inert gas is injected into the space among the seal rings, and then penetrates into the inner chamber of the centrifuge and the external environment through the narrow sealing clearance.
The pressure of inert gas is higher than those of the inner chamber of the centrifuge and the external atmosphere, therefore, entrance of air into the inner chamber of the centrifuge or escape of the gas out of the inner chamber of the centrifuge can be avoided.
Seal of the centrifugr
Attention: due to the principle of sealing, some of the injected inert gas will leak into the surrounding environment. Therefore, it is required to make sure that there should be enough oxygen in the operation environment. It is necessary to install an additional environment monitoring system (such as gas detector) so as to ensure personnel safety.
Found in 1993, Jiangsu Huada Centrifuge Co., Ltd. is located at Zhangjiagang City, an emerging port city in China, which is situated in China’s most economically advanced Yangtze River Delta region, with convenient traffic and beautiful environment.
