Quality control points of the aluminum bronze pump body casting
- Nov 27, 2017 -


In the process of machining the aluminum bronze pump body casting, usually through many different processing links, mainly refers to the molding objects obtained by casting method. That is to say, the aluminum bronze pump body casting is actually in the smelting of liquid aluminum bronze material into the pre-prepared cast, and then after cooling, grinding processing and other processing means to have a certain shape, size and performance of objects.

So, how to control the quality of aluminum bronze pump castings? The quality of the casting includes not only the appearance quality, but also the internal quality and use quality. The appearance quality mainly refers to the surface roughness, surface defects, size deviation, shape deviation and weight deviation. The internal quality refers mainly to its chemical composition, physical properties, mechanical properties and so on.

In practical applications, we also pay particular attention to the use quality of the aluminum bronze pump casting because it is directly related to its actual performance, such as the durability of the work under different conditions, including wear resistance, corrosion resistance, fatigue and other properties such as machinability, weldability, and so on.

In general, the quality of aluminum bronze pump castings has a great influence on the mechanical properties of the products. For example, the size, accuracy and surface roughness of the impeller, shell and other parts of various pumps will directly affect the working efficiency, energy consumption and cavitation development of the pump body. So what are the factors that will affect the quality?

According to the actual production situation, there are many factors may affect the quality of aluminum bronze pump castings to varying degrees. The important factors include the design process, casting process and the quality of the raw materials used in the aluminum bronze pump castings. In addition, it should also pay attention to the actual process operation, to make a reasonable process operation procedure.
