2. DESCRIPTION OF COMPRESSOR
2.1. Design
The machine covered by this instruction book is a single cylinder, 2-stage single-acting water-
cooled air compressor. The design principle is shown in the cross-sectional drawing Fig. 2,
page 31.
The first stage of the compressor is the low-pressure stage (LP) and the second is the high-
pressure stage (HP). Air circulation through the compressor is shown in Fig. 3, page 32. The
letters indicate:
A. Suction filter
B. LP suction valve
C. LP delivery valve
D. LP safety valve
E. LP cooler
F. HP suction valve
G. HP delivery valve
H. HP cooler
I. HP safety valve
The big-end bearing is a two-shell plain bearing and the gudgeon pin bearing is an undivided
press-fitted plain bearing. The big end and gudgeon pin bearings are pressure-lubricated
from a gear pump mounted on the end of the crankshaft. The crankshaft bearings are two-row ball
bearings.
Vertical cooling tubes are rolled into the compressor cylinder block. These serve to cool the air
after first-stage compression and again after second-stage compression. The cooling water intake
and outlet are located so that the water circulates through the cylinder block and ensures
efficient cooling of the air and compressor cylinder walls.
The compressor compresses air from atmospheric pressure to rated pressure, with an upper limit
of 35 bars.
The compressor is designed for installation together with an electric motor or other drive unit on a
well-stiffened base, with a flexible coupling between compressor and motor.
Every compressor is tested before delivery from the factory, and all compressor sets supplied
complete with motor are aligned before dispatch. See chapters 3.1. and 5.6.
This compressor is designed to supply compressed air for engine starting, and for the operation
of air power equipment and instruments. It complies with the requirements specified by the
classification institutions.
2.2. Safety equipment
The compressor is fitted with two safety valves, one after the first-stage compression and the
other after second-stage compression.
The safety valves, which are set at the factory in accordance with the working pressure specified
by the customer, ensure that the pressure does not exceed the limit for which the compressor
and compressed air system are dimensioned.
The cylinder block cooling jacket is fitted with a safety plate which will blow out if the cooling
water is subjected to excessive pressure. Use only manufacturer's genuine safety plates to
replace blown plates.
The compressor's automatic control equipment normally comprises a pressostat which shuts
down the compressor if the tube oil pressure falls below the minimum limit.

3. INSTALLATION AND OPERATION
3.1. Installation instructions
Every compressor unit is supplied complete with drawings and specifications showing its dimen-
sions and attachment points. The customer also receives installation instructions giving recom-
mendations for the installation of equipment and piping.
The compressor unit should be installed in a location where the air is not excessively warm.
Warm intake air reduces the capacity of the compressor. Normally, the ambient temperature for
electrical equipment should not exceed 45°C. The compressor unit bedplate should lie plane to
its foundation. After the unit is installed, check the alignment of compressor and motor. The
procedure is shown in Fig. 4, page 32.
Use vernier calipers or inside micrometer calipers to check the distance (W) (Fig. 4). This should
be the same around the whole circumference of the coupling.
Using a micrometer (A), check the radial misalignment between the coupling halves as shown in
Fig. 4. The maximum micrometer reading (A) should be as illustrated in Fig. 4.
Even if the unit has been installed on vibration dampers, an alignment check is to be recom-
mended after installation.
Piping should be so installed that there is no risk of water pockets.
Other equipment should not be installed around the compressor unit in such a way that inspection
and maintenance operations may be hampered.
3.2. Cooling water system
It is of the greatest importance to the operation and life of the compressor that a good and reliable
supply of cooling water is ensured. The quantities of cooling water required are given in Table
T.1, page 35. These specifications apply to both seawater and freshwater cooling.
Whether the compressor is connected to a central cooling system or has its own separate cooling
water pump, it is important to ensure that the cooling water is circulating properly. In this
connection it is not sufficient simply to check that the compressor pressure gauge is registering
cooling water pressure.
If the cooling water feed temperature is too low, increased internal condensation may result. If
this is the case, the cooling water temperature should be increased. If the temperature cannot be
increased by recirculation, condensation can be reduced by reducing the supply of cooling water.
The cylinder block cooling jacket is equipped with a thermometer for the monitoring of cooling
water temperature.
Recommended cooling water temperatures are given in Table T.2, page 35.
3.3. Starting up
Before initial starting up and after long periods out of use, carry out the following operations:
•Check the oil level.
•Check that the quality of the oil has not been impaired by water or other foreign matter.
•Check compressor valves and lubricate the cylinders with oil.
•Turn over the compressor by hand, with the suction valve relieved by means of the man-
ual valve opener.
•Check cooling water circulation.
•Check that the air line cock between the compressor and the air reservoir is open.
•Open the manual drain cocks on the water trap.
4/26

Sperre Air Compressor
Two stage, water cooled
Model: HV1/140A
•Start the compressor and check the oil pressure.
If everything is operating normally, close the drain cocks and set the valve opener in the
operating position. Allow the compressor to run for a few minutes before loading it to maximum
working pressure.
3.4. Operation
During normal operation, pressures and temperatures should be as shown in Table T.2, page 35.
Some of the values, which are directly affected by local conditions, may deviate slightly from the
figures in the table.
Operation of the compressor is normally monitored by the automatic features of the starting
equipment, e.g. thermostat monitoring of cooling water temperature. However, additional regular
checking of operation and automatic functions is recommended.
In operation, a certain amount of water will always condense out of the compressed air. As
delivered from the factory, the compressor is fitted with manual drain cocks after the LP and HP
coolers and if these are not operated by automatic draining equipment, manual draining must be
performed regularly. Also, the oil and water trap must be regularly drained, manually if no automatic
draining function is provided.
3.5. Stopping
Stopping the compressor manually for short periods:
•Operate the manual valve opener to relieve the LP suction valve. -
•Open drain cocks on water trap and compressor.
•Stop the compressor.
If the compressor is to be shut down for a long period, e.g. when a ship is to be laid up, the
procedure is as follows:
•Lubricate compressor valves, non-return valves, cylinder walls and exposed crankshaft
surfaces with corrosion-inhibiting oil, suitable for the envisaged period of shutdown.
•If there is any risk of frost, drain the cooling water from the compressor.
•Drain off old oil, clean the sump and refill with new oil.
•Set the manual valve opener in the horizontal position to relieve the load on the suction
valve.
•Turn over the compressor manually once a month.
•The starter cabinet and other electrical equipment should also be protected from damage
by corrosion.

5. INSPECTION AND MAINTENANCE
IMPORTANT: PERSONAL SAFETY
Before starting any kind of work on the compressor, the electricity supply must be switched
off at the starters and also at the main switchboard. Hang a notice on the switch on the main
switchboard to show that repairs are in progress.
5.1 Maintenance schedule
The following maintenance schedule is intended as a guideline for normal maintenance.
However, compressor operating conditions vary widely from installation to installation and it is
therefore important to adapt the maintenance schedule to the experience of the individual
operator.

5.2. Valves
In the parts lists and drawings each valve is shown complete, with its own part number, and also
dismantled with the part numbers of the individual components.
After overhaul or replacement of parts, assemble the valves in sequence as shown in the
drawing of the dismantled valve.
When assembling valves, lubricate the nut and valve bolt and tighten to the torques (in kpm)
given below:
Dimension Minimum Maximum
M8 1.0 1.2
IMPORTANT:
Before attempting to check compressor valves, loosen the clamping screw on the valve cover
before removing the cover.
After inspecting and overhauling valves, it is essential that the clamping screw, which bears
against the valve clamping piece and which keeps the valve in place on its seat, should be tightened
with an unbrako key to the torque shown in Table T.3.
Overhaul and maintenance of valves
Regular and careful maintenance of valves is essential to the capacity and reliability of the
compressor. We therefore recommend overhaul in accordance with the following guidelines:
When cleaning and dismantling the valve, never clamp the valve directly in a vice to loosen the
centre bolt nut. A special clamping jig for this purpose, suitable for all valves, is available from the
factory on request. A simple makeshift for clamping the valve is to set it in a vice between two
pins which fit into the outermost seat slots of the valve.
Clean the valve components and check them carefully. IMPORTANT: Never use sharp
implements on sealing surfaces and plate parts.
Replace all parts that are worn or even slightly scored. Check that all guide pins are in order.
Maximum wear limit is 10% of the total thickness of components.
If a valve spring or spring plate shows signs of weakness, all springs must be replaced at the
same time, because damage can result if some springs operate longer than others. Replacement
of all valve springs is recommended after about 5000 hours running time, even if the springs do
not look worn.
If there are signs of abrasion or scoring of the valve seat sealing ledges, these must be
machined. Most valves are drilled for guide pins, with spare holes for new pins. Guide pins can be
driven out by means of a suitable tool. If it proves impossible to remove a broken pin, use one of
the spare holes.
To remove the valve centre bolt, mark the centre of the pin with a centre punch and then drill out
the pin. Remove the centre bolt. After refitting the bolt, drill a hole for the safety pin, drive the pin
securely into place and peen the end to prevent it from falling out.
After completion of machining and careful replacement of guide pins in their respective holes in
the valve seating and/or catch plate, check that the ends of the pins do not butt against the
bottom of the holes in the matching parts.
Use only genuine replacement pins and parts.

Assembly of valves demands precision, care and forethought. Make sure that the various parts
are correctly located and that the right numbers are installed. Compare with the lists and
drawings of parts to ensure that the right number of parts is present. Total lifting heights of valve
plates are given in Table T.4.
5.3. Lubricating oil system
The lube oil pump is a gear pump which is normally capable of operating for long periods without
maintenance. The pump is driven direct from the end of the crankshaft, and the lube oil pressure
is controlled by means of a by-pass valve in the pump. When maintenance is to be performed,
loosen the pump flange, disconnect the oil pipes and withdraw the pump.
On the suction side of the pump there is a filter which can be easily dismantled for cleaning.
For the lubrication of the LP side of the piston, the compressor is fitted with a small piston pump,
driven by an eccentric from the crankshaft. The oil for the piston pump is taken from a separate
reservoir mounted on the side of the compressor. The type of oil used in the compressor
crankcase should also be used in the separate reservoir. The quantity of oil fed to the LP suction
valve can be adjusted by means of a regulating valve, fitted on the suction side of the pump.
When the compressor is warm, the normal feed should be 3-5 drops per minute.
IMPORTANT:
Accumulation of condensate in the crankcase may present a serious problem under certain
operating conditions, and it is important that the operator should check from the very beginning
whether condensate in the lubricating oil is liable to become a problem.
Unless the condensed water emulsifies with the lubricating oil, it will separate out and there is a
risk that the compressor will be lubricated with water.
The choice of lube oil is of great importance to the reliable operation of the compressor. The
manufacturers have performed extensive tests of lube oils for the oil companies, and the following
is a list of lubricants recommended on the basis of these tests.
A list of recommended types of oil is affixed to the compressor on delivery.
Following synthetic lubricants are tested and recommended by SPERRE:
•BP ENERSYN RX 100
•CASTROL AIRCOL SN 100
•CHEVRON HD COMPR. OIL 100
•DAPHNE MARINE COMPRESSOR 100
•ELF PRIMERIA SG 100
•ESSO/EXXON SYNTESSTIC 68
•MOBIL RARUS 827
•NIPPON OIL CO. FAIRCOL SA100
•STATOIL COMPWAY S 100
•TEXACO SYN STAR DE 100
5.4. Bearings
The compressor has replaceable, two-shell plain big-end bearings. The crankshaft bearings are
two-row ball bearings.
The gudgeon pin bearing is a single shell plain bearing, press-fitted into the little end. Toler-
ances and clearances for connecting rod, crankshaft and gudgeon pin bearings are given in
Table T.4, page 37.
10/26

Sperre Air Compressor
Two stage, water cooled
Model: HV1/140A
All plain bearings are pressure lubricated.
After inspection or replacement of the big-end bearing it is important to ensure that the bearing
does not bind on the crankshaft. It must be possible to turn over the compressor manually.
New two-shell bearings are coated with a running-in compound at the factory.
Dismantling the gudgeon pin bearing from the connecting rod
A. Use a hydraulic pressor extractor to remove the old bearing shell.
B. Press in the new bearing shell.
C. Adjust the fit of the bearing to the gudgeon pin in accordance with Table T.4.
5.5. Piston and piston rings
Dismantle the piston as follows:
A. Remove the cylinder head without dismantling the valves.
B. Unscrew the big-end bearing bolts and remove the lower bearing shell.
C. Withdraw piston and connecting rod.
Reassemble in the opposite sequence.
5.6. Flexible coupling
The compressor flywheel serves as one coupling half.
Dismantling the coupling
A. Loosen the nuts on each coupling half and give each one a sharp tap with a hammer before
removing them completely. This will cause the bolts to loosen from their conical holes in the
coupling halves.
B. Remove the bolts and take out the flexible coupling. Avoid spilling oil on the flexible coupling.
The coupling half on the motor is keyed and shrunk on to the axle.
Alignment
The principle and values for checking alignment are shown in Fig. 4, page 32.
A. Micrometer/dial indicator
B. Magnetic base
C. Flywheel
D. Coupling half, motor
E. Flexible coupling
Check the angle (W) by means of inside micrometer callipers or vernier callipers. The distance
(W) in mm should be the same around the whole circumference of the coupling halves.
Check parallel misalignment (A) between coupling halves as shown, around the circumference of
the coupling halves (C). Values in mm for maximum parallel misalignment are given in Fig. 4.
5.7. Coolers
To ensure reliable operation of the compressor it is important to keep the LP and HP coolers free
from deposits of carbon and cooling water salts etc. Insufficient cooling causes excessive air
temperature and progressively increases the formation of carbon deposits.
The cooling tubes are rolled (or expanded) into the cylinder block at both ends. If the cooling tubes
show signs of severe corrosion or wear, the old tubes can be drilled out and new tubes rolled (or
expanded) in.
5.8. Filter
The air filter should be cleaned by means of a good degreasing agent. Blow the filter clean with
compressed air and give it a thin coating of compressor oil.
Oil filter: Clean with a good detergent and blow through with compressed air.
