What is the best way to extend the life of alloy spectacle plates?

Everyone who has ever used a concrete pump knows what a "cobalt plate" is. This is the wear part of the concrete pump. It is often referred to as the 'spectacle plate' because it looks like the glasses people wear.

In fact, there is a more technical name for the wear plate, which people call it because it is very similar in shape to glasses. Don't underestimate this little gadget. The glass plate is an essential part of the concrete pump. Despite its small size, it is quite technical and expensive to process.

Talking about this little thing, it costs more than 2,600 dollars for one piece as well. Because the wear layer wears out quickly during use, it must be replaced after a certain period of time. In order to save costs, we have to find ways to extend the service life of the "spectacle plates".

What is the best way to extend the service life of alloy spectacle plates? Let me tell you: the wear-resistant layer is repaired with a wear-resistant welding rod and polished with a grinding machine before being put into use. It works well and extends the service life of the "spectacle plate". It should not be a problem to transport 3,000 cubic metres of concrete (new "spectacle plates" have a service life of 8,000 - 10,000 cubic metres).

Cobalt plates are wear parts and their main forms of failure are wear and tear and breakage. The wear between the spectacle plate and the cutting ring is abrasive wear, which first appears as a blunting of the angles between the cutting ring and the spectacle plate, forming a small wedge-shaped mouth with a rounded surface. As the size of the abrasive grain increases, the wear gap increases. When the gap reaches a certain value, the construction will be affected by serious slurry leakage.

However, as the pumping height increases, the impact shear of the cob plates will increase and the wear will become more severe and prone to fracture and collapse. Once damaged or failed, we must replace them in time to ensure the normal operation of the whole concrete pump truck.
