Rising ring, also known as piston ring, sealing rising ring. Traditional modeling is an incomplete ring, is a very common on the Roots fan accessories, playing the main role is a sealing type of role. Seal ring ring outside diameter close to the inner wall of the sleeve, relying on the ring free elasticity to make the two close together. In the upper and lower axial direction to play a sealing effect. Sealing ring up ring broadly speaking, a lot of machinery need to use this sealing device, Roots blower of different models are also used in this sealing ring, so that the sealing ring up ring can be described as a very large number of types. S42 sealing ring up ring is Changsha Roots blower factory S type Roots blower on a...

Changsha Roots Blower Factory S51 sealing ring is one of the seals in the Roots fan, the sealing ring is a kind of ring seal with a notch, place it in the ring groove of the sleeve, the sleeve and the shaft together with the rotation, the sealing ring by the elasticity of the notch is pressed together and pressed against the wall of the inner hole of the static parts, you can play a sealing role. Usually, the quality of a Roots fan depends on the sealing effect of this Roots fan, take Changsha Roots fan S51, S51 series fan has decades of production history, has been the user's favorite products. The main reason is that the S51 Roots fan is imported from foreign advanced technology produced, which...

Precautions in the assembly of Roots fan: First, check the disassembled parts for any damage, special attention should be paid to checking the mating parts, if damage is found, it should be repaired or replaced. Secondly, the bearings should be washed clean and then coated with lubricating oil. When installing the bearings, the tools, hands, etc. should be cleaned. Thirdly, the dust on the mating parts should be removed thoroughly and then coated with oil. Fourth, if the gasket is broken or lost, then the gasket should be replaced with the same thickness and material. The steps for assembling the Roots fan are as follows: First, install the wall plate on the drive side on the casing. Second, install the impeller section from the gear end into the casing. Third, install the wall plate from the gear end...

Radial clearance of bearings Due to the different working conditions in which the bearings are located, the clearance is divided into three types: original clearance, fit clearance and working clearance. Original clearance - bearing clearance in the free state before installation. Fit clearance - bearing assembly to the shaft shell clearance. The size of the clearance is determined by the amount of interference. Fit clearance is smaller than the original clearance. Working clearance - bearing in the work, due to the temperature difference between the inner and outer sleeve so that the fit clearance is reduced, but also due to the role of the work load, so that the rolling body and the elastic deformation of the collar to increase the clearance, but in general, the working clearance is greater than the fit clearance. Bearing axial clearance Some bearings, due to the structural characteristics of the ...
