1. High strength:When excavators work, the piston inside the engine needs to withstand huge pressure and impact. PC400-5 6D125 excavator diesel engine piston is made of high-strength materials, or through special treatment process, so that it has high strength, can maintain the stability of the structure under harsh working conditions, and is not easy to deformation or damage to ensure the normal operation of the engine.
2. Good wear resistance:The piston is constantly moving in the engine, and there is frequent friction between it and the cylinder wall. In order to ensure the service life of the piston, this type of piston has good wear resistance.
3. Accurate dimensional accuracy :For the engine, the mating clearance between the piston and the cylinder wall is very critical. The PC400-56D125 excavator diesel engine piston has precise dimensional accuracy and can perfectly match with the cylinder wall.
4. The most efficient heat dissipation performance:Diesel engine will produce a lot of heat during the working process, the piston as a direct contact with high-temperature gas components, need to have good heat dissipation performance.
