3Z-3.33/165 type Oxygen/Nitrogen Compressor (product code is H318) is a vertical, three row, five stage, water-cooled cylinder non-lubricated piston compressor which is ancillary unit for KDON-180, KDON-350, KDON-550 air separation equipment.
3Z-3.33/165 type Oxygen/Nitrogen Compressor’s motion mechanism adopts vertical three row piston type motion mechanism, the piston force is 3.5 tons. Its lubrication mode of lubricating oil is difference with other manufacturers’ simply throwing type. The crankshaft, connecting rod, crosshead pin, copper sleeve and bearing bush drill with oil holes, in the operation pressure of 0.12-0.30MPa, lubricating oil cooling by oil cooler and through oil holes and direct injection of each movement contact surface, forming oil film in these movement contact surface and take away the heat generated by friction. The unit has greatly extended the life, and decrease shaft power.
The piston of Oxygen/Nitrogen Compressor is adopts advanced spherical structure connection, the fourth stage and fifth stage piston automatically find the center of cylinder line, it makes the piston and piston ring always reciprocating motion at the center of cylinder line(Self centering), greatly prolong the service life of piston ring and bearing bush.
The external cooler adopts water-bath stainless steel coil as cooling pipe, Maintenance simply, only need remove connecting tube and lift out of the cooling coil for descaling.
