Definitions

  • the liner 9 defines a compression cavity 92 of the air compressor. It can be seen that it will be easy to, by independent process in advance, make the smoothness of the inner surface of the inner liner 9, i.e., the compression cavity, be able to be at least greater than the surface smoothness of the cylinder's cylinder block itself. Such improvement of the smoothness of the inner surface of the compression cavity effectively increases the service life of the air compressor, significantly increases the number of working cycles, improves the working efficiency, reduces the production cost, and can avoid the high local performance requirements of the material of the molded part.
  • Such separately manufactured liner may be machined from deep drawn tube having the advantage that the inner sidewalls of the compression cavities no longer have draft angles like in casting.
  • the inner sidewall of such separately manufactured liner may be in a straight cylindrical shape, and the shape and size of the cross-section of the liner at both ends are the same. Due to the elimination of draft angle, this straight cylindrical design is advantageous for increasing the degree of matching of the piston within the compression cavity, avoiding the degradation of its performance and durability due to the friction and angle of the inner sidewalls of the compression cavity, and making the product more compact and make the work efficiency higher.
