The diesel generator piston set consists of a piston, a piston ring and a piston pin. The piston is the pressure of the gas and transmits the force to the crankshaft via the connecting rod. The working condition of the piston is very bad. It is continuously moving at high speed and reciprocating linear motion under the action of high temperature and high pressure gas. Due to the reciprocating inertial force of the periodically changing gas pressure, the piston is subjected to large mechanical and thermal loads, and uneven temperature distribution causes thermal stress. Therefore, the piston must not be too heavy and have sufficient strength and rigidity.
Whether in the process of purchasing or using diesel generator sets, the fuel consumption of diesel generators and the fuel consumption of diesel generator sets have always been a concern of users. However, many users do not know the size and calculation method of diesel generator fuel consumption. In general, the fuel consumption of diesel generator sets is related to the following two factors:
Diesel generator valve drive is mainly composed of camshaft, timing gear, tappet, push rod, rocker arm and rocker shaft. The function of the valve train is to open and close the intake and exhaust valves at a specified time (gas timing) and order (fire order), and to ensure a certain degree of opening.
Aluminum and aluminum alloy aluminum oxide is easier to oxidize than copper. It forms a dense and refractory alumina film with high melting point. It is difficult to melt during welding, hindering the fusion of matrix metal, easily causing weld metal slag, reducing mechanical properties and resistance. Corrosive; aluminum has a large gas absorption, liquid aluminum can dissolve a large amount of hydrogen, when it is rapidly cooled and solidified, hydrogen can not be precipitated, and pores are easily generated
