Cast aluminum piston for marine diesel engine
We can provide 160-400 mm diameter high-hardness integral aluminum alloy casting pistons for marine diesel engines. Their general characteristics: the piston ring groove is made of high-hardness, high-nickel-iron material, The application of this material may increase the pressure resistance outside the groove, and at the same time, the internal temperature of the piston can be kept at a constant temperature, which is the better performance of the aluminum skirt. The piston cavity allows an inner cooling oil passage to cool the piston in time to keep the piston optimal Thermal load state; the piston pin hole is lined with high-strength alloy bushings, especially on high-load diesel engines. Since the above three different kinds of materials appear on one piston at the same time, we need to pay more efforts in the process, we use die casting and a series of control methods to ensure that the iron material of the piston ring groove parts and the local aluminum alloy can be tightly attached together, and each piece of piston and every process has undergone our various strict inspections...
