Technical features of DF-E compressor:

 1) The structure of the machine body adopts the structure of an integral fully enclosed rib structure, which is characterized by a large number of main bearing stalls, compact arrangement and strong rigidity;

2) The single crank single row and short crank radius structure are adopted for the crankshaft, so the bearing capacity of the crankshaft is improved, the transmission torque is enhanced and the matching is flexible. In addition, the characteristics of high speed and small turning radius also reduce the starting torque of the unit.

3) The structural characteristics of crosshead are mainly embodied in the torque control structure connected with piston rod. DF-E unit adopts a "super nut" structure, which differs from the connection structure designed in China in that Orient  Technology decomposes the pre tightening problem of the big thread of the piston rod into the pre tightening problem of the small thread.

4) The cylinder can be lubricated with or without oil. The cylinder materials include cast iron, ductile iron, steel or forged steel. The cylinder block is basically designed as a "through cylinder" structure. All the fillers are installed in the stuffing box. The stuffing box flange is clamped between the cylinder and the adapter, which can be used as a transition piece to connect with the adapter, greatly enhancing the versatility of the cylinder in different series of applications. The calculated "local cutting" shape is used at the end of the cylinder head and the stuffing box, also for the control consideration of reducing the air flow resistance of the air valve and the cylinder clearance.

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. The piston rod thread is pressure rolled, and a variety of self-lubricating organic material piston support rings and piston rings are used. According to different working environments, support rings can be designed into components, whole structures, etc. According to different specific pressures, single or multiple support rings can be used to combine. The width of a single support ring is limited by the standard.
