What causes alloy spectacle plates to affect the efficiency of pumping?

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 failure in the form of chipping and shedding, which can affect the efficiency of pumping to a large extent. Cemented carbide spectacle plates are extremely hard and have excellent wear resistance and are used extensively in concrete industrial pumps.

What causes alloy spectacle plates to affect the efficiency of pumping?

The role of alloy spectacle plates.

1, reduce the cost of use, it replaces the wear between the S valve inlet and the material cylinder outlet with the wear between the eye plate and the cutting ring. The cost of replacing a set of eye plates and cutting rings is thus much lower than the cost of replacing the S-valve and material cylinder.

2、Improve the sealing, because there is a rubber compression ring between the cutting ring and S valve it plays a cutting ring to the eye plate a pre-pressure, so as to improve the sealing between the cutting ring and the eye plate.

3, the concrete pump truck cutting ring and the eye plate between the aggregate has a cutting role, so as to ensure that the cutting ring and the eye plate between the correct in place.  

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

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

Generally speaking, when the concrete ratio is reasonable (commercial concrete), the service life of the glasses 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 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, glasses plate, cutting ring clearance will also affect the service life

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