case description
    The abbreviation of concrete pump pipe is often referred to as 砼 pump tube because it is called tóng. It is easy to understand that the pump tube is a new type of construction engineering accessory product that appears at the same time as the concrete pump. The appearance of the pump tube greatly improves the efficiency of the construction. It requires a manual barrel or a crane or a crane. The operation of the bucket was changed to quickly transport the concrete to the place where it was poured, which increased the construction efficiency by nearly a hundred times.

Process comparison

    The pump tube is made of special material steel tube, which is quenched by internal wall and carburized chemical treatment. The hardness of the flange bushing reaches 58-60 degrees, and the service life of the pipe is increased by 3-5 times, which saves users time and expense. The trouble of frequent replacements increases production efficiency. The performance and life of a quenched 砼 pump tube and a quenched 砼 pump tube are different. The quenched 砼 pump tube can transport nearly 10,000 cubic meters of concrete.

Equipment composition

The special equipment for quenching the inner wall of super-audio pump tube developed by our company consists of four parts: 
1. New XXYPI-160 super-audio special quenching equipment. 
2, GY-40 CNC quenching machine. It is a set of tooling matched with the power supply. When quenching, the inner wall of the pump tube is quenched evenly. The pump tube must be moved at a uniform speed along the shaft. When the pump tube is tilted during quenching, the water during quenching can flow out. 
3, coaxial water-cooled sensor: This sensor is designed by our company for the quenching of pump tubes. It is sprayed with water while quenching to ensure that the pump tube is not deformed.

4. Double cycle closed cooling system.
