Physical properties of copper castings of pump body and their influence on mechanical products
- Nov 05, 2018 -

Copper castings of pump body usually have good mechanical and physical properties. Different products can have a variety of different strength, hardness, toughness and comprehensive performance, and can also have one or more special properties, such as wear resistance, high temperature resistance and Low temperature, corrosion resistance, etc. The quality of the copper castings of the pump body mainly includes the appearance quality, intrinsic quality and quality of use.


The so-called appearance quality mainly refers to the surface quality of the copper castings of the pump body. The intrinsic quality mainly refers to the chemical composition, physical properties and mechanical properties of the castings. The quality of use refers to the working durability of the cast copper parts under different conditions, including Wear resistance, corrosion resistance, chilling heat resistance, fatigue, shock absorption and other properties as well as machinability, weldability and other process properties.


In practical applications, the quality of the copper castings of pump body has a great influence on the performance of the mechanical products. In fact, the size of the impeller, the housing and the internal cavity of the various types of pumps, the accuracy of the profile and the surface roughness directly affect the working efficiency of the pump and hydraulic system, the development of energy consumption and cavitation. Therefore, it is necessary to utilize the manufacturing process of the cast copper piece to improve the performance and quality of the product as much as possible.
