How to install the air ring of a Roots pump
Thread Content
During the first repair, several gas rings were already damaged
How is it broken? Did it break during installation or after it started operating?
The installation went wrong; I don’t know the correct way to do it. This thing is too difficult to install
Did it break when trying to install it on the shaft, or what happened?

It’s a ring plug seal; the hole that fits with the ring plug is severely worn. The new hole is a through-hole, and creating a labyrinth seal using it would make installation difficult. Even if installed, the sealing effect would still be poor. The sealing mechanism works in the same way as that of a reciprocating compressor piston ring: the hole should be a through-hole, with the ring plug expanding to create a seal against the hole. The end cover should be replaced or modified by creating a ring plug sleeve, enlarging the hole in the end cover, and fitting the sleeve in place before welding it in.
These are piston rings, which are installed on the piston ring bearings; there’s no other way – practice makes perfect, or else apply a little oil
The end cover area is worn; a cemented carbide sleeve is installed after the shaft is enlarged. However, the sleeve needs to be secure, and it is best to assemble it with heat applied from the outside and cooling from the inside
