CPI
valve design
CPI’s team of valve and compression engineers, using
our sophisticated valve dynamics programs, can not
only carry out valve performance modelling for design
purposes, but can also analyse existing installations
and assess whether the optimum valve design is being
used. Together with an R&D programme that is
focused on all aspects of valve design detail, including
reliability, efficiency, ease of installation and
maintenance.
Un-loaders
CPI valves can be supplied with suction valve un-loaders
of various types, such as finger-type and plug-type
un-loaders.
Actuators
CPI also supplies a range of quality valve un-loader
actuators, designed specifically for each application.
CPI
compressor valve dynamics study
When designing new valves CPI is able to study the
predicted performance of their valves under known
operating conditions and to derive suction and discharge
valve motion, PV diagram, pressure drops, power
loss, anticipated gas velocities, valve disc opening
velocity, volumetric efficiency and piston loadings,
to give optimum design solution.
Trouble
shooting and performance analysis
Using wide field experience accumulated by CPI across
a broad variety of compressor applications and with
the predictability available from an effective valve
dynamics program CPI is able to recommend changes
to resolve poor reliability issues. By using its
valve dynamics study capability, CPI is also able
to look at existing installations and recommend
improvements to existing compressor valves, either
of a similar type or involving a change from other
valve types, such as ported plate, concentric flat
ring, poppet or channel, to the CPI preferred valve,
with its emphasis on performance improvement and
power savings. |
