Maximum Allowable Reciprocating
Weight
Each compressor frame has
a maximum allowable reciprocating weight limit. This weight is based upon
the total combined weight of the connecting rod assembly, crosshead assembly,
crosshead nut and piston / rod assembly. The maximum allowable reciprocating
weight limits are included in the limitations set within the Ariel performance
program.
Reciprocating weight will affect
the inertia load, and therefore the combined rod load. Ariel publishes
gas rod load limits,
and maximum allowable reciprocating weights, rather than combined rod
load limits. It is possible to exceed the maximum allowable reciprocating
weight with some piston/crosshead combinations, and should be avoided.
Ariel's performance program will
monitor maximum reciprocating weights versus rotative speed and provide
application limitations within the weight balance section.
Refer to Ariel Corporation Electronic
DataBook Cylinder Details for rotative speed limitations for the various
frames and cylinder classes.
