Technical features of DF-A compressor:

1）The machine body is made of cast iron. It is a closed mechanism with crosshead slideway and crankcase connected. The main bearing is self-aligning rolling bearing.

2）The crankshaft is made of forgings and is attached with a two sector balance iron to balance the unbalanced weight of the rotating part and the first order inertial force of the reciprocating part.

3）The main bearing bush and connecting rod big end bush are made of babbitt alloy, and the small end bush is made of bronze.

4）The cylinder can be lubricated with or without oil. The cylinder materials include ductile iron, cast steel, welded carbon steel or stainless steel and forged steel.

5）The piston is made of cast iron, forged steel, aluminum alloy and other materials; The piston rod is made of alloy steel and stainless steel to meet various applications.

6）The air valve, including various forms and materials, can meet various use requirements. High temperature resistant valve material provides better reliability, impact resistance, corrosion resistance and pollution resistance. There are mainly four types of valves: annular, reticular, grooved and mushroom. Our company's gas valve dynamic performance calculation program can be used to analyze the full load or partial load operating conditions, so that the gas valve can achieve greater reliability, while reducing power consumption and gas loss.

7）The body lubricating mechanism drives the gear pump from the outer end of the crankshaft, filters and pressurizes the cooled lubricating oil in the crankcase, and then enters the crank shaft from the end of the crankshaft to lubricate the big end bushing of the connecting rod, and then flows through the small end bushing from the central oil hole of the connecting rod, and then through the crosshead to lubricate the crosshead slideway, so that all friction surfaces are lubricated.
