Construction Machinery Parts Engine Piston DB58 For Doosan Daewoo
The thickness of the piston generally tends to decrease. It is mainly restricted by the two contradictory factors of the combustion pressure and the reduction of the temperature gradient.
The thickness is too thin, the ability to bear mechanical load is poor, will cause mechanical deformation; If the thickness is too thick, the temperature gradient is too large, causing too much thermal stress and thermal deformation. Therefore, the piston head thickness varies with the maximum combustion pressure of the engine, the cylinder diameter, whether there is oil cooling, and the combustion chamber form.
Piston top wall using heat flow type, that is, from the top to the ring piston area wall transition arc radius is bigger, some still increase support jin (typically 4), the purpose is to make the piston at the top of the heat can be more smoothly to ring and pin (support and strengthen the stiffness and strength of the important role of piston), thereby reducing the heat of the first ring and ring groove, improve the reliability of piston group of key parts.

Piston type & surface treatment
Piston with alfin reinforcement are resistant to compression ring groove wear . the alfin reinforcement also act as a heat barrier minimizing heat conduction from piston skirt area. Such pistons can thus withstand the demand for higher load and highet performance engine .
Created for operation in high temperature environment like turbo engines. Through oil circulation in the gallery, pistons are intensively cooled in the piston crown and ring belt area .
Anodization of piston crown creates a hard crown surface thus providing pistons with extra protection against crown piting and wear .
Tin coated surface provides extra lubrication and smoother running of cylinder components resulting in longer engine lifetime .
Help produce less frictional heat and engine noise. The extra lubricative effect also minimize cylinder bore wear and prevent piston scuffing .
Reduce tge fructuib from with the cylinder liner . And to protect the piston from corrosion .
The nitriding products have excellent wear resistance, fatigue resistance, corrosion resistance and high temperature resistance .
1. Enough stocks for sale.
2. Quick and safe delivery ,various of transportation way: Sea, Air, Bus, Express, etc
3. High quality with competitive price
4. We can develop new items for you especially
Q: What is your MOQ?
A: We do not have MOQ . We accept lower quantity for your trial order.
Q: Can I customized my own Brand ?
A: Yes, we can do, however you need to reach certain quantity for each item
Q: Can we print our company logo on product and package?
A: Yes, but the quantity of the order is required. And we need you to offer the Trademark Authorization to us.
