Non-contact mechanical seals for fans:

Fan is a fluid machine that relies on input mechanical energy to increase gas pressure and discharge gas. It is the habitual abbreviation of gas compression and gas conveying machinery in my country. Generally speaking, fans include fans, blowers, compressors and Roots blowers, but do not include displacement blowers and compressors such as piston compressors. Gas compression and gas transport machinery is a machine that converts rotating mechanical energy into gas pressure energy and kinetic energy, and transports the gas out. 122 mechanical seal

There are many classification methods for fans. According to the structure and working principle, they can be divided into centrifugal fans, axial fans, mixed-flow fans and cross-flow fans. It is widely used for ventilation, dust exhaust and cooling of factories, mines, tunnels, cooling towers, vehicles, ships and buildings; ventilation and induced air for boilers and industrial furnaces; cooling and ventilation in air conditioning equipment and household appliances ; Drying and selective delivery of grains; Air source of wind tunnel and inflation and propulsion of hovercraft, etc.

Here, taking the turbo compressor as an example, the non-contact mechanical seals used in it are introduced one by one. The non-contact mechanical seals for compressors are divided into gas film seals and oil film seals (belonging to liquid film seals).　　951.html,
