Changsha blower can not be separated from the seal in the process of using, then Changsha blower common seal form are those?Changsha Blower FactoryTake a look.
Mechanical seal is a common sealing means in Changsha Roots Blower, mechanical seal according to the combination of the way and wallboard structure type, usually Changsha Roots Blower mechanical seal is divided into closed wallboard - single mechanical seal, closed wallboard - four mechanical seals, open wallboard - four mechanical seals three types. Three types of mechanical seals have their own advantages and disadvantages.
Mechanical seals utilize sealing liquid for lubrication and cooling. The sealing liquid is generally turbine oil, and when oil is not allowed to be used as sealing liquid, clean water or other suitable medium can also be used as sealing liquid. When working, pumping system or self-circulation system should be used to circulate the sealing liquid in the sealing cavity.
When the Changsha Roots Blower is running, the moving ring of the mechanical seal rotates along with the shaft, which is the oil in the sealing cavity flowing in the downward direction and generating centrifugal force. Due to the absorption of the frictional heat of the seal end face, the temperature of oil in the seal cavity is higher than that in the circulating oil tank. Therefore, after the oil flows into the sealing cavity from the circulation tank, its volume expands, its specific gravity becomes smaller, and buoyancy is generated. Due to the centrifugal force and buoyancy, the relative displacement of the oil mass point is caused, so as to achieve the purpose of convection heat transfer. In addition, at the entrance of the upper oil pipe, the oil, due to the squeezing block of the braking mechanism, changes the flow direction and then goes up along the upward oil pipe, circulating automatically in the direction shown by the arrow. After being properly cooled in the circulating oil tank, the oil flows into the sealing cavity through the downstream oil pipe, continuously taking away the friction heat of the sealing end face, and at the same time, keeping the friction vice in a good lubrication state.
