Concrete pump trucks can continuously transport concrete under high pressure, making them indispensable in the construction of buildings, bridges, and tunnels. Central to their operation are the conveying cylinder and the hopper, linked by a crucial transition sleeve. This sleeve often endures significant friction, leading to severe wear. To combat this, traditional sleeves have an inner wear-resistant layer made of flux-cored wire or high-chromium welding rods. However, these materials often fail, becoming uneven and deformed under extreme pressure. Additionally, some sleeves utilize high-strength ceramic alloy sheets bonded with adhesive. Unfortunately, gaps between these sheets allow for concrete erosion, causing the sheets to detach prematurely. In contrast, the transition sleeve of the concrete pump truck by Lizheng Machinery features a robust hybrid wear-resistant layer made of hard alloy and high-chromium alloy. This innovative combination results in a smooth inner wall with superior pressure resistance and a significantly extended service life, surpassing that of traditional welded and ceramic-adhesive layers.
