Description of the inert gases and mechanical seal structure: The special seal structure formed by inert gases and mechanical seal can prevent the outside air from permeating through the inside of the centrifuge and prevent the inside gas from leaking to the outside environment. Mechanical seal consists of several seal packing ring, which isolates the inflammable and explosive gases inside the centrifuge and the outside air; Injecting the inert gases into the seal packing ring, the gases permeate the inside and outside environment of the centrifuge through the narrow seal gap and the pressure of the inert gases injected is higher than the inside and outside environmental air pressure of the centrifuge (differential pressure of the inert gases injected can be controlled); Therefore, when uninflammable and un-explosive gases (inert gases) are generated within the enclosure of the centrifuge, the explosive gases generated by inflammable and explosive materials can not mix with the oxygen in the air, which ensure safe operation of the centrifuge. The using scope of the explosion prevention centrifuge: Solid or liquid separation of inflammable and explosive materials in chemical, petrochemical and pharmacy industries; Gases can not be leaked to the outside air during solid or liquid separation process. Explosive-proof grade of the explosion prevention centrifuge: DIIBT4.
