Do you know what the pump truck spectacle plate does?

The role of the pump cobbler and the cutting ring, which replace the wear between the inlet and the material cylinder, is to protect the service life of both. They work on the following principle: under the preload of the unfolding nut, the rubber spring is compressed and the cutting ring fits closely to the spectacle plate. The cutting ring and the spectacle plate belong to the relative movement coupling parts, after generating wear, the rubber spring can rely on its own elasticity to compensate for the wear of the spectacle plate and the cutting ring, eliminate the wear gap.

Do you know what role the pump truck spectacle plate has?

Cost reduction role: due to the role of the pump truck spectacle plate and cutting ring, they replace the wear between the inlet and the material cylinder, protecting the service life of both. They work on the following principle: under the preload of the unfolding nut, the rubber spring is compressed and the cutting ring fits closely to the spectacle plate. The cutting ring and the spectacle plate belong to the relative movement coupling parts, after generating wear, the rubber spring can rely on its own elasticity to compensate for the wear of the spectacle plate and the cutting ring, eliminate the wear gap.

When the wear of the cutting ring of the pump truck reaches a certain level, the compression of the rubber spring is zero and there is no pressure on the cutting ring, the unfolding nut can be tightened and the S-tube welding body can be pulled back to restore the compression of the rubber spring, so that the glasses plate and the rubber spring can be compressed and the gap can be compensated. This way the sealing performance of the spectacle plate and the cutting ring is well ensured.

It is worth noting that the rubber spring compression should be in accordance with the requirements of the regulations, too small will affect the sealing of the spectacle plate and cutting ring, too large will cause early wear and tear of the cutting ring, shortening the service life, the cutting ring and spectacle plate are currently using carbide structure to improve the service life.
