The main components of diesel engine fuel system include fuel injection pump, fuel injector assembly, fuel injector, plunger assembly, fuel delivery valve assembly and other precision components.Low alloy wear-resistant steel and its vacuum heat treatment process Its manufacturing process includes casting, forging, stamping, cold extrusion and metal cutting and other soft processing forming technologies before heat treatment. After heat treatment, it needs to be finished by grinding, honing, grinding, EDM, Optimization of vacuum heat treatment of spring electrolysis and other processing methods. After the processing of parts is completed, assembly and performance testing should be carried out according to the prescribed procedures. Only after passing the test can it leave the factory as a finished product.Vacuum heat treatment process for steel parts In addition to requiring high hardness and wear resistance after heat treatment, the material of precision coupling parts should have high tempering resistance and dimensional stability, good corrosion resistance and contact fatigue strength, and small linear expansion In addition to the coefficient, it should also have good machinability.Vacuum heat treatment process for steel parts
