BCL series refers to a multi-stage, vertically split, barrel
type centrifugal compressor,available for medium and high pressure
purpose. The compression can be made in a single stage, two stages
or multi stages in one compressing casing , the maximum working
pressure can reach up to 70 MPa . There might be 2-10 impellers in
one case.It can be designed with gas extraction or gas injection,
and be supplied as a train with multi casings (same as MCL series).
This series centrifugal compressor is mainly used for various
medium and high pressure industrial plants and classified
as,BCL,2BCL and 3BCL .
II- BCL series centrifugal compressor features that the inlet
and outlet nozzles are on the casing and impellers are arranged in
the same direction.
11- 2BCL series centrifugal compressor characterizes that the
compression is made in two sections and the impellers are
. back to back arranged . Generally two types of this series are
available,one is equipped with an intermediate exhaust nozzle on
the casing and an inter- stage cooler: the other is equipped with a
circulation stage, which is formed as an independent section .
11- 3BCL series centrifugal compressor is classified into three
types, one is designed with gas extraction and gas injection
nozzles on the casing, the second one features that the compression
is made in three sections with two inter-stage coolers: the third
one characterizes that the compression is made in three sections,
with a circulation stage and an inter-stage cooler .

Carbon ring seal is nonnaLly used with medium and low pressure
compressor .The carbon
seal is made up of several segments, which are fastened at its
outer circumference with
spring. The number of carbon seals mounted in the seal. body is
determined upon
pressure. With help of shaped grooves on the inner circumference
and ends of carbon
rings, a gas film may be formed between the carbon rings and
rotating shaft during
operation, which may reduce the leakage and achieve optimum
sealing effcet.

Journal bearing shall be of elliptical shoe or Wting
pad type. The Wting pad bearing is often consisting
of 5 babbitted segments, used for restricting
resonance and keeping running rotor in its axial
position . Each pad is embedded with a temperature
sensor for monitoring bearing temperature at times.
Self-leveling, bi-direction thrust bearing will assure
the rotor in its correct position . The pads of thrust
bearing are also fitted with temperature sensors .
