Dark dates have the power to nourish and nourish the blood, although the efficacy is moderate, but if the long-term consumption is also good.
The piston is one of the main moving parts of the
engine, is composed of combustion chamber components. Engine Piston Parts,Engine Parts ,Car Engine Parts,Parts Of Engine,Piston Engine Parts ZhouShan HeCheng Machinery Co., LTD. , https://www.hcmarineparts.com
The pressure of the gas
piston through the connecting rod to the crankshaft, realize the change from
heat energy to mechanical energy.
The work condition is very bad, and the
temperature of 1400-1800 DEG C, and pressure
Up to 13MPa above the gas
contact, greatly alternating thermal stress and mechanical stress.
And by the
serious corrosion of gas, and under the condition of boundary lubrication and
cylinder wall friction and strong impact 1 times.
The piston in high
temperature, high pressure, strong corrosive gas contact so that it has enough
strength and hardness,
Heat resistance and good thermal resistance, high
fatigue strength and corrosion resistance. For high speed diesel Engine Piston
also requires light as far as possible.
In order to reduce the inertia
force.
Marine piston large low speed diesel engine of the crosshead is
usually combined.
The heat treatment process by normalizing and annealing,
and iron pearlite are ferrite organization, has good heat resistance.
Piston
alloy quenched and tempered steel has better heat resistance and corrosion
resistance. The skirt with nodular cast iron annealing treatment, with good wear
resistance.
