About Us Greenfir offers a complete line of reciprocating
compressors, many built to strict API 618 and ISO 13631 standards,
and all backed by a global service network. These comprehensive
capabilities allow us to manage a wide range of energy conversion
projects for our clients. We can engineer, manufacture, procure,
test, deliver, install, operate, and maintain your entire
compressor system. Our extensive application experience with all
major drive systems, including motors, engines, and turbines-allows
us to precisely match the drive train to the compressor for maximum
efficiency and reliability. We also provide all compressor
accessories, piping, and packaging necessary to meet your total
process and installation requirements. Our packaged units are ready
for modular installation, with all compressor drive, lubrication,
coolant, pulsation dampening, and control systems in place. This
integrated approach simplifies ordering, delivery, and
installation; reduces your coordination time and expense; lowers
your engineering and construction costs; and provides singlesource
accountability. Product Description The compressor adopts
symmetrical and balanced structure, with two throws, two cylinders
and two-stage compression. The cylinders are respectively located
on each side of the frame. The gas inlet and outlet ports of the
cylinders are arranged according to the upper inlet and lower
outlet, with double function. The cylinder is equipped with an
independent jacket, which is cooled by circulating water. The
compressor will be located indoor with one layer arrangement. The
distance piece adopts D-type long and short double compartments in
article 6.12.1.5 of API 618, and the compartment is equipped with
integral metal cover plate with gasket. The average piston speed is
3.564 m/s. The crankshaft speed is 594 r/min. The actual gas outlet
temperature (@cylinder flanges) is ≤ 100 °C. The cylinder and
packing case are with oil-free lubrication design and less oil
lubrication operation. The compressor capacity control adopts the
combined control of bypass and pneumatic unloading. Use the
pressing-off suction valve for unloading. All unloading valves are
air unloading, the load selection switch is located on the local
instrument panel of the compressor unit, with 0, 50, 100% third
gears, and the unloader is finger type. At the same time, "Stage-1
outlet reflux Stage-1 inlet" manual adjustment loops and "Stage-2
outlet reflux Stage-1 inlet"(Automatic regulating valve group) are
equipped for capacity control and starting the compressor unit
without load. Utilities
