Alloy spectacle plate cutting rings

The spectacle plate and cutting ring are a fragile component used in concrete machinery and equipment such as trailer pumps, pump trucks and truck mounted pumps. The cutting ring of the alloy spectacle plate is pressed under the preload of the unfolding nut, and the rubber spring is pressed, so that the cutting ring and the spectacle plate are closely fitted. The cutting ring and the spectacle plate belong to the relative movement coupling parts, after producing 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 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.

There are several reasons that affect the service life of the carbide spectacle plate cutting ring as follows.

First, the differences in the concrete pumped by each site concrete pump truck

Generally speaking, when the concrete ratio is reasonable (commercial concrete), the service life of the spectacle plate and cutting ring is longer. In the Chongqing area, for example, the service life of the cobalt plate can be more than 120,000 square meters, while the life of the cutting ring is between 15,000 and 40,000 square meters.

Second, the differences in the pumping working conditions of each site pump truck

In the height of large, long distance pumping concrete conditions, glasses plate and cutting ring because of the larger back pressure, so its life expectancy to be shorter.

Third, carbide glasses plate, cutting ring clearance will also affect the service life

The cutting ring has a large pre-tightening force, so it can be tightly pressed on the glasses plate. When pumping, the mortar will not be able to enter. In this case, the wear of the spectacle plate occurs on the whole plane and the wear is more uniform, so its life is also longer.
