Sintered Oil Pump Impeller
The sintered oil pump impeller is a core component of an oil pump manufactured using powder metallurgy sintering technology. It is formed by mixing and pressing metal powders in proportion, and then sintering them into dense impeller parts at high temperatures. It is used in various oil pumps to drive the flow of fluid media such as lubricating oil and hydraulic oil.
- Product Introduction
Materials and Processes
Selection of sintering materials
• Iron based alloy: the most commonly used sintered material, with low cost and easy forming. By adding elements such as carbon, nickel, and chromium, the hardness and wear resistance can be improved, making it suitable for heavy-duty industrial oil pumps, diesel engine oil pumps, and other scenarios .
• Copper based alloy: has good thermal conductivity and anti friction properties, suitable for scenarios with high noise control requirements such as high-speed low-noise oil pumps and hydraulic system oil pumps .
• Hard alloy: with tungsten carbide as the hard phase and cobalt as the binder, it has extremely high hardness and is suitable for extreme wear-resistant scenarios such as oil pumps and mining machinery oil pumps that transport media containing solid particles .
Advantages of sintering process
• Near net forming: Powder metallurgy sintering can directly produce impellers that are close to the final shape, reducing subsequent machining and lowering production costs .
• High material utilization rate: Compared with traditional casting processes, the material utilization rate can be increased by more than 30%, reducing waste .
• Advantages of mass production: suitable for large-scale production, good product consistency, and stable quality .
