2 OUTLINE

A Structure and Performances of Compressor

(Refer to Section 12 STRUCTURAL DRAWINGS FOR COMPRESSOR)

1) Main Unit

This is a vertical 2-stage compressed air cooling type compressor

It is designed to match a normal pressure of 30 kgcm2

The features of this compressor are high-speed operation simple structure rigidity and good

performances For its structure the upper part of a cylinder is a low-pressure area and its

lower part is a high-pressure area

The stepped piston performs suction and delivery and compresses air by being moved

vertically by means of a connecting rod

The air is compressed in the low-pressure area for the first time after having passed the air

strainer and air inlet valve located at the inlet of the compressor The compressed air is cooled

while it is passing through an air cooler body and it enters in the low-pressure area

separating drainage The air recompressed in the high-pressure area is set to a specified

pressure

However it enters in the air cooler body once again due to a high temperature and is sent to

an air receiver after its temperature has been lowered Since heat generation is of a

considerable amount due to compression cylinder cover and air cooler are cooled by cooling air

2) Main Accessories

(1) Air inlet valve

This is for adjusting an air intake rate If the compressor is operated with the air intake valve

closed the consumption rate of a lubrication oil will increase

Be sure to keep the air intake valve fully open at any time

(2) Low pressure suction and delivery valve

For its structure a suction valve seat is located at its lower part and a delivery valve seat at

its upper part to unify suction and delivery This is a feature of the Jonghap compressor Since

a valve area is widely allowed it requires a less lift of the valve

Consequently it endures high-speed rotations and does not lower its efficiency Since the valve

consists of an unified body it can be easily removed for disassembly and rapair

(3) High pressure suction and delivery valve

This high pressure valve can be also easily removed for disassembly and repair Depending on

a compressor model a suction valve and delivery valve are separated or unified as the

low-pressure suction and delivery valve

- 7 -

(4) High pressure safety valve

This valve is attached to prevent a danger when a pressure becomes abnormally high When

the pressure increases within 10 of the normal pressure it is actuated and discharge the

compressed air into the atmosphere to prevent a pressure rise Its working pressure can be

easily controlled by means of an adjusting bolt

(5) Air cooler

This air cooler is installed to cool the high-temperature compressed air and to separate the

drainage

(6) Pressure gauge

A low pressure gauge is attached to check whether the valves are correctly actuated Although

it depends on a compressor model it will indicate 45～9 kgcm2

when the compressor is

normally operated (at 30 kgcm2

)

Be sure to close a cock when operating the compressor Open the cock only when checking an

indicated pressure

(7) Oil gauge

The lubrication oil in crank case is scraped up by oil scraper up by oil scraper at the lover

part of connecting rod to lubricate to cylinder (high pressure area) piston area metal area

crank pin and main bearing The oil mist fully filled in crank case is lubricated to cylinder (low

pressure area) and low pressure valve area by oil pipe and oil consumption can be observed by

this oil gauge from outside

An upper line indicates a standard oil amount For details refer to section 8 B

3 PRECAUTIONS FOR INSTALLATION

A Installation Site and Air Intake

Select a place with less dust and moisture for air intake

Install the unit at a place where it is light enough for the conveniences of inspection

disassembly and repair Its foundation must be firm lest the unit should be vibrated

B Lubrication Oil

Since the compressor is delivered without its lubrication oil filled be sure to supply it before

operation (Remove the cover of the crank case and supply the oil up to the upper line of the

oil gauge) For the types of oils refer to Section 8 A

C Air receiver and Piping

Mount the air receiver as close to the compressor as possible

Do not bend the piping at an acute angle

4 PRECAUTIONS BEFORE AND AFTER START-UP OPERATION

A Inspection

Viewing the whole unit thoroughly check once again whether or not each part is properly

tightened whether or not the oil is sufficiently supply

B Manual Rotation

Rotating calmly and manually the pulley check whether or not there is any abnormality inside

the compressor When a considerable force is required in compressing or when a honk-honk

or pang-pang sound is heard in sucking it indicates a desirable condition

However when it is felt that something is hit it indicates a failure

Disassemble and inspect the unit

C After start-up Operation

Let fall a few drops of oil from an oil supply cup located at the upper part of an air inlet

port (This procedure is required when there is not oil inside the cylinder after installation Is

can be omitted when the unit has been always used) Although a rattling sound may be heard

immediately after the oil is supplied it will stop in a short time because it is caused by the

irregular movement of the valve due to the oil

Check whether or not an atmospheric pressure is increased opening the cock of the low

pressure gauge

5 OPERATIONAL PRECAUTIONS

A Air tightness

Check whether or not the air leaks from air passages (Piping joints valve sealing areas and

so on) or whether or not the oil leaks

B Lubrication Oil

Although its amount cannot be accurately checked unless the unit is stopped care should be

fully taken on the consumption of the oil

Initially check the consumption rate of the oil stopping the unit after having operated it dor

4～5 hours For the oil amount refer to Section 8 B

C Sound

If there is any abnormal sound immediately stop the unit and check its cause because it

indicates a serious accident

- 9 -

D Safety valve

Be sure to check once whether or not it is actuated at a specified pressure

E Heat

Although the temperature of each part keeps on increasing for approximately 20 minutes after

having started the operation of the unit if it still keeps on increasing it indicates on

abnormality

Although the temperature of a compression area may exceeds 100 depending on a model if

other parts are too hot to tough by hand check its cause immediately because it indicates an

abnormality

Also pay attention to the heat generation of the pulley caused by slippage

F Drainage

When the unit is operated for a long time drainage will remains

Drain it by opening a drainage cock It can be thoroughly drained due to the atmospheric

pressure if the cock is opened during the operation of the unit

6 PRECAUTIONS FOR STOPPING OPERATION

A Before Stopping Operation

Let fall a few drops of the oil from the oil supply cup located at the upper part of the air

inlet port

This procedure is necessary to prevent rust while the operation of the unit is stopped

Accordingly if the unit is always used it can be omitted

B Lubrication Oil

Viewing the oil gauge if the oil level is close to a bottom line supply the oil When this is

done it can be also supplied from a breather pipe by removing its cap If the unit is operated

for a long time the oil is contaminated by the drainage or impurities Replace the oil depending

on its condition For details refer to section 8 and 11

C Drainage

Drain by opening the drainage cock

Note When the unit is operated for a long time the oil is contaminated by the

drainage or impurities

Replace the oil with a new one before it is too late (Refer to Section 11)

10 TROUBLESHOOTING

A In Case a Pressure Cannot Be Increased

(1) Leakage form the piping line

The air may leak form the piping joints and air receiver more or less Check a leak point

with soap water and repair it

(2) Damage of the valve

The valve may be worn out due to a long time of operation or it may catch dust or it

may be damaged by heating If the pressure cannot be increased at all it indicates the

damage of the valve In this case disassemble and check it immediately If the pressure

cannot be increased smoothly it indicates that the valve seat is damaged by catching the

dust or that the valve contact is deteriorated by the deformation of the valve due to

heating in this case check the following items operating the unit Closing the air inlet port

with hand if the air is returned in this sucking condition the low pressure suction valve is

defective And if the low pressure gauge indicates too low when compare with test record

the low pressure delivery valve is defective if the low pressure gauge indicates too high

the high pressure suction valve and delivery valve are defective The suction valve is

mainly defective when the unit is in operation and the delivery valve is defective when the

unit is not operation

(3) The air inlet valve is closed

(4) Abrasion of the piston ring

When the unit is operated for a long time the piston ring is worn out Replace with a

new one

(5) Excess feeding of the lubrication oil

An excess feeding of the lubrication oil in crank case brings excess scraping of the

lubrication oil which may deteriorate the function of valve Pay attention to a noise (lasting

long) which can be heard in this case

- 15 -

(6) Insufficient tightening of the low-pressure valve seat

If the valve seat is not sufficiently tightened because the cylinder comes into contact with

the cylinder cover or because the O-ring of a connection pipe is obstructive the

compressed air may flow reversely (through the clearance of the packing located at the

upper part of the low-pressure valve seat) or it may flow away flow away in the

atmosphere Through the clearance of the packing located at the lower part of the

low-pressure valve seat This can be found by covering the air inlet port with hand

because the air is not sucked in If the cylinder cover is removed it can be confirmed that

the valve does not come into firm contact with the packing Increase the number of the

packings on the upper part of the valve seat and tighten firmly

B In Case There is an Abnormal Sound

Since this indicates a serious accident immediately stop the operation of the unit and check its

cause

(1) In case the top of the piston comes into contact with the bottom of the low-pressure valve

Refer to Section 7 C-6

(2) In case pulley of flexible coupling key is loosened

(3) In case a clearance is increased due to the abrasion of the piston pin metal

If an abnormal sound can be clearly heard it indicates that the piston metal is

considerably worn out

It can be found only by slowly moving the piston In this case since it is likely that the

crank pin metal is worn out remove the cylinder cover and check the movement of the

piston

(4) In case a clearance is increased due to the abrasion of the crank pin metal

Remove the crank case cover This cause can be confirmed by slowly rotating the crank

shaft and viewing the very part If it cannot be still confirmed move the connecting rod

vertically using a long bar

(5) In case there is no clearance in the high-pressure area

If a high-pressure clearance (clearance of a stepped area) is extremely small the

compressor is hardly resisted when it is rotated by hand and it causes a sound when it is

operated Take out the packing between the cylinder and crank case to increase the

clearance in the high-pressure area

When this is done since the top clearance (between the top of the piston and the bottom

of the low-pressure valve) is also changed increase the number of low-pressure valve

packings (large) for adjustment

- 16 -

C In Case the Unit is Overheated

1) Although come parts of the unit such as the compressed air outlet high-pressure valves and

air piping may become too hot to tough by hand it is not abnormal

2) In case a V pulley is hot

It is because a belt slips If it is a V-belt it smells of the burning of rubber

Check the tension of he belt

3) In case the whole compressor is hot

(1) In case the cooling air amount is proper

If the cooling air is not sufficient or does not exist at all the compressor is overheated

and it causes the sticking of the piston


Heat is generated because the compressed air is not properly sent to the air receiver

Check whether or not the compressed air passages such as the high- and low-pressure

valves non-return valves and so on are clogged by carbon

Since the heat may be generated when the diameter of the pipe between the compressed

air outlet and air receiver is too narrow or when the non-return valve of the air receiver

This unit feeds air automatically by ONOFF switch of power source of motor by pressure

switch

(1) Descriptions of performances

Automatic operation

Stopping operation

When the pressure inside the air receiver reaches a specified upper limit the contact of

the pressure switch ① is opened and the magnetic switch ② is actuated to stop the

motor

At the same time since the current to the magnetic valve is shut off the valve is

opened and the drainage and residual air inside the 1st stage compression area ④ are

discharged into the atmosphere The non-return valve ⑤ is closed to prevent the reverse

flow of the compressed air inside the air receiver

Starting operation

When the pressure inside the air receiver reaches a specified lower limit the contact of

the pressure switch ① is closed and the magnetic switch ② is actuated to start the

motor

The timer on delay ⑧ works and the magnetic valve ③ is closed in approximately 10

- 17 -

seconds The 1st stage compression area ④ is shut off from the atmosphere and the

operation of the compressor opens the non-return valve ⑤ to fill the air receiver with the

air

Adjustment

The working pressure can be easily adjusted by the spring of the pressure switch ①

Manual operation

If the AUTO amp MANUAL exchange switch ⑦ is turned to MANUAL the unit can be

arbitrarily started and stopped by the push button switch ⑥ apart from the air pressure
