The materials of the eyeglass plate of the pump truck include high chromium alloy cast iron, tungsten carbide, cemented carbide and alloy ceramics. These materials are widely used in the manufacture of eyeglass plates for pump trucks due to their excellent wear resistance and hardness. Eyeglass plate, also known as wear-resistant plate, is an important part of the concrete pump truck. It is named because of its shape like glasses. It is located on the pumping distribution valve of the pump truck and is connected to the concrete delivery cylinder. Under working conditions, the eyeglass plate and the cutting ring form a cutting friction force, which bears the strong friction with the concrete and the impact force generated when cutting the stone. Therefore, choosing the right material is crucial to ensure the long-term use of the eyeglass plate and the normal operation of the pump truck. Materials such as high chromium alloy cast iron, tungsten carbide, cemented carbide and alloy ceramics are ideal choices for making eyeglass plates due to their excellent wear resistance and hardness.
