The
companys
cylinder liner
generally applies the
materials of wear-resistant alloy cast iron
containing chromium or boron, such as HT****7,
HP-CuCrMo, etc.
The inner surface of the cylinder liner is also sometimes chrome
plated (loose hole chrome plating, chrome plated
at oil storage
outlets), and nitriding or phosphating treatment to
improve wear resistance. The inner
surface hardness of
cylinder liner is usually greater than HB**0, and has a good match
with the hardness of piston
ring. The inner surface should
have appropriate roughness to make it have a
certain oil storage capacity and running-in
performance. The inner surface should be of
sufficient roundness and cylindricity accuracy, and the mounting
support should have a high
positional accuracy against the inside bore
center.
The inner surface of cylinder is easy to wear
because of high temperature and high pressure
gas and contact with pistons at high-speed
motion. In order to improve the wear resistance and
prolong the service life of the cylinder, different cylinder
structure and surface treatment methods
are provided. There are
three types of cylinder structures: no
cylinder liner type,
dry cylinder liner type,
wet cylinder liner type.
Non-cylinder liner type means that no cylinder liner body is
embedded, and the
cylinder body is directly worked out
of the body, which
has the advantages of shortening
the cylinder center distance and
reducing the size
and the weight of
the body. But the cost is high.
Dry cylinder liner is not in contact with the
coolant, with the
wall thickness of 2~3mm, the outer surface and cylinder liner seat
hole inner surface
must be refined to ensure the necessary precision and
easy removal, which has the
advantages of high rigidity, small central distance of the
cylinder, light weight and simple processing technology. The
disadvantage is that the heat transfer is poor, the temperature
distribution is uneven, and the local deformation is easy to
occur.
The outer
wall of wet
cylinder liner is in
direct contact with the
coolant, with the wall
thickness of 5~8mm, which realizes the
radial positioning by using the
upper and lower positioning ring, and
realizes axial
positioning with the
help of corresponding bearing
surface mating
between the
upper flange of
cylinder liner and the top
of the body, which has
the advantages of the absence of sealed
water jacket on the
body, easy casting, good heat
transfer, even temperature
distribution and easy repair without removing
the engine from the vehicle when replacing the cylinder
liner. But the body
stiffness is poor, and easy
to leak.
