Carbide spectacle plates, cutting rings

The spectacle plate, also known as the wear plate, is an important part of the concrete pump truck. It is shaped like an eyeglass plate and is therefore called an eyeglass plate. The cutting ring, also known as the wear ring, is an important part of a concrete pump truck. It is shaped like a ring. It is called a cutting ring because it works in a shearing motion. Both the spectacle plate and the cutting ring are important parts of a fine concrete pump and have the same role and use.

Some wear-resistant alloys are prone to chipping, falling off and other forms of failure, which can largely affect the efficiency of pumping. Cemented carbide spectacle plates and cutting rings are extremely hard and have excellent wear resistance and are used extensively in concrete industrial pumps.

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

A. The differences in 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 should be 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 1.5 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.
