Rod Load Definitions
External Rod Load
The external rod load of a reciprocating compressor is a calculation
considering the unit in a static state. The calculation for deriving the ERL is:
ERL = PD(HA) - PS(CA) where:
PD = Discharge Pressure (psia) at the cylinder flange
PS = Suction Pressure (psia) at the cylinder flange
HA = Head end surface area of the piston
CA = Crank end surface area of the piston
Internal Gas Rod Load
The internal rod load is often referred to as the internal gas rod load
of a reciprocating compressor and the terms are synonymous. The IRL
is a dynamic rod load calculation based upon the internal gas pressures
within the cylinder bore. These gas pressures take into account the dynamic
pressure drop characteristics found across the valves and the gas passages.
The IRL is calculated through the 360 degree rotation of the crankshaft with
the highest values being used.
Net Rod Load
The net rod load is considered a dynamic rod load rating. The NRL is
the sum of the IRL calculation and the inertial loads of the reciprocating
weights. The NRL is calculated through the full 360-degree rotation of the
crankshaft with the highest values being used.

Lubrication
MH and WH Frames
The complete lubrication system of the compressor consists of two parts
which are of equal importance:
• The system that provides lubrication to the frame running parts;
• The system that provides lubrication for the cylinders.
Both systems use oil from the frame sump. Refer to Engineering Standard
1002 (page 4-44) for lube oil specifications. These Standards deal with frame
lubrication; refer to the cylinder data book for information about cylinder
lubrication.
A gear-driven lubricating oil pump is flange-mounted to the frame with
a pressure relief valve included for cold start protection. A shell-and-tube
oil cooler, shipped separately for remote mounting, is provided. The cooler
is constructed of copper or admiralty tubing with threaded oil and water
connections. Other features include a low oil pressure shutdown switch and
an oil level sight glass. All the necessary piping is supplied and mounted.
Oil pressure should be 45 – 55 psi and is maintained at this level by
the pressure relief valve. If adjustment is required, this can be done by
removing the cap which gives access to the spring-loaded adjusting screw.
This adjustment should be made at normal operating speed and temperature.
WG and W7 Frames
The complete lubrication system of the compressor may be conveniently
divided into three parts which are of equal importance:
• Lube oil from the frame sump provides complete protection of all
frame running parts.
• A separate, independent, force-feed lubricator and tubing system
provides lubrication for cylinder walls and piston rod packing.
• A shell-and-tube cooler is provided for frame oil cooling.
The frame lubrication system consists of a gear-driven pump, pressure relief
valve, oil cooler, and oil filter. Oil pressure should be 35 – 40 psi for W7
frames and 45 - 55 psi for WG frames and is maintained at this level by
the pressure relief valve. If adjustment is required, this can be done by
removing the cap which gives access to the spring-loaded adjusting screw.
This adjustment should be made at normal operating speed and temperature.

Frame Lubricant and Lubrication Suggestions
Provided that the compressor’s crankcase is sealed off from the cylinders,
a good mineral oil which provides resistance to oxidation and corrosion is
generally satisfactory to use. However, there is no objection to the use of a
detergent type of oil if it is more readily available. To assure oil suitability,
use a product of well known merit produced by a responsible concern and in
accordance with the manufacturer’s recommendations.
In some cases it may be convenient or practical to use the same type
of oil in the compressor as is used in the compressor drive engine. This
is permissible as long as the engine oil is of proper viscosity. Superior
recommends SAE 40 for all normal compressor operation and SAE 30 when
ambient temperatures are below freezing. Refer to Engineering Standard
1002 (page 4-44) for further information.
If start-ups are to take place when the ambient temperature is below freezing,
the pour point of the oil must be low enough to insure flow to the oil pump.
Heavier oil should be heated before starting.
If a compounded oil is used, the non-corrosiveness of this oil must be looked
into very carefully. The oil must not contain substances which might be
injurious to tin- or lead-base babbitts. It is also highly desirable that it be
noncorrosive to copper-lead alloys.
The oil level in the frame sump should be checked while the compressor is
running. The correct level is shown by the sight gauge on the auxiliary end
of the compressor. Oil level (while running) should be no higher than the
top and no lower than the bottom of the sight gauge. Oil is added through
the breather cap hole in the top cover. The breather cap is designed to be
threaded into its bushing by hand and no wrenches are to be used. Makeup
oil may also be continuously added through an optional, frame-mounted oil
level controller connected to an oil supply tank. (Note: the regulator is not
designed to make up large quantities of oil in a short time period, such as
refilling the crankcase after oil or filter changes, but simply to compensate
for small oil losses which normally occur during operation.)
Oil change periods, in general, may be longer than the period required for
compressor drive engines. An initial break-in period of 300 to 500 hours is
recommended. Thereafter, the oil and filter element change interval can be
increased to 2000 hours or longer, provided that the filter element remains in
good shape and the oil remains reasonably clean. Experience will determine
when to change the filter element and the oil.
i
(See the lubrication
logic diagrams in
the individual frame
model sections of this
data book.)
1-12
In the case of the W7 frame, when a new element is installed in the
filter a sufficient amount of lubricating oil must be added into the filter
to compensate for that which has been drained from it. After a new filter
element is installed, add oil to the top of the filter canister. Replace the lid
and vent the line. The vent connection is a special orifice fitting. Do not use
a standard fitting at this location.

Component Features
Base (Crankcase)
The base is made of high strength alloy iron and is heavily ribbed and
reinforced for maximum rigidity. Large spacer bars provide further stability
and easy reassembly. The top and end covers are individually removable
to provide easy access to moving parts. Our open-top design allows the
crankshaft to be easily removed. An oil sump is provided in the lower
portion of the base. The line-bored main bearing supports have matchmarked and numbered caps, which must be assembled accordingly.
Crankshaft, Thrust and Main Bearings
The complete crankshaft assembly includes the drive end oil slinger and
the auxiliary end drive gear. Both of these are shrunk onto the crankshaft,
eliminating the need for keyways and keys. The crankshaft is drilled to carry
lubrication from the main bearings to the connecting rod bearings.
The thrust bearing is a “half washer” type. It fits into a groove machined
in the main bearing saddle and is held captive by the crankshaft, the main
bearing saddle, and the main bearing cap. Plain and thrust main bearing
shells are of the split, non-adjustable, precision type and are located via tang
slots. The lower half can be rolled out with the tool provided when the tool
kit is ordered (see the special tool list, page 3-15).
The upper and lower main bearing shells are interchangeable. However, once
the compressor has been run it is preferable that the shells be kept in their
original positions. Therefore, upon removal of the bearing shells, they should
be so marked.
Connecting Rod and Bearings
The connecting rod is a steel forging, rifle-drilled to provide lubrication to
the crosshead pin bushings. The crankpin end of the rod is split and retains
the precision-type bearing shells by means of four alloy steel bolts clamping
the cap and rod together. The cap is aligned to the rod by dowels and both
parts are precision machined as an assembly. A complete assembly must be
ordered if replacement is necessary.

Crosshead Guide
Removable, heavily ribbed iron castings with integral distance piece.
Auxilliary distance piece available as an option for corrosive gas service.
Large covers on both sides for easy inspection and access to the crosshead,
connecting rod, and rod packing. The crosshead can be removed through
these openings without disturbing the cylinder mounting. The fasteners
holding the crosshead guide to the base must be torqued uniformly (using a
crisscross pattern) to prevent cocking of the guide relative to the base and
crankshaft. (See Recommended Bolt Torque Values tables, pages 3-7 through
3-10, for torque values).
Lubrication to the crosshead slide areas is handled differently by the WH6/
W7/WG and the MH6 frames. On the WH6/W7/WG, lube oil is sent entirely
via internal oil passages. On the MH6 it is directed internally through the
frame and then tubed externally at the crosshead guide and the bearing.
Crosshead
The crosshead is made of ductile iron and has removable top and bottom
shoes which have durable bearing material on the sliding surface. Screws
and locknuts hold the shoes firmly in place. These must be torqued
uniformly to the figure specified in the Recommended Torque Values tables
(pages 3-7 through 3-10).
Auxiliary End Cover
The auxiliary end cover is aligned to the base and located by a dowel.
Additional dowels in the auxiliary end cover provide proper location for
attaching the lube oil pump drive carrier and the force feed lubricator drive
carrier.
Both the lube oil pump and force feed lubricator carrier assemblies are
fitted with precision bushings which may be replaced without disturbing gear
alignment or backlash.
Drive End Cover
The old drive end cover, which is found in a few of the early units, is aligned
with the base by two dowel pins. An additional dowel pin is used in the
end cover to locate the seal cover. The seal cover has a close pilot fit in
the end cover.
Most of the frames have the new one-piece drive end cover, which is aligned
to the frame via two dowels.
