How to improve the service life of carbide spectacle plate cutting rings?

As building heights continue to rise, pumping heights increase and pumping pressures also increase, which makes sealing more and more demanding. On the other hand, the strength, viscosity and low pumpability of the concrete are also testing the wear resistance of the wear parts in key parts of the pumping equipment. One of these key wear parts is the spectacle plate, which is also known as a wear plate because it is shaped like spectacles. Cemented carbide spectacle plates have high hardness, strength and excellent wear resistance, and are a more ideal material for spectacle plates.

How to improve the service life of carbide spectacle plate cutting rings?

To improve the service life of the spectacle plate cutting ring, the first step is to start with the following aspects.

1. The ratio of concrete varies from site to site and there are differences, resulting in serious wear and tear of the spectacle plate and cutting ring. So try to improve the concrete ratio, so that the service life of the glasses plate and cutting ring can be longer.

2. Large differences in pumping conditions at each site. When concrete is pumped at high heights and long distances, the spectacle plates and cutting rings will be subjected to great back pressure, resulting in a shortened service life. So try to reduce the conveying height and distance.

3. In addition, the incorrect installation of the spectacle plate and cutting ring makes a large gap between them, and the mortar will enter the gap when pumping, resulting in uneven friction between the spectacle plate and cutting ring, which damages the contact surface and reduces the service life.
