Maintenance

4.1

General

outline

For

different

types

of

generator

sets,

users

need

to

refer

to

the

matched

engine’s

operation

and

maintenance

manual

to

implement

correct

maintenance

operation.

In

order

to

obtain

maximum

operation

safety

and

life

expectancy

of

the

generator

sets,

periodic

maintenance

is

very

important.

Strictly

observance

of

the

terms

on

generator

set’s

maintenance

can

ensure

generator

set’s

performance

and

reduce

its

damage

to

environment.

Correctly

identify

and

strictly

observe

the

labels

(drawings,

words

and

warnings

etc.)

On

diesel

generator

sets

can

be

of

great

help

to

correct

maintenance

and

safe

operations.

Maintenance

of

the

generator

sets

shall

be

made

when

it

has

been

stopped

and

the

cable

which

connect

to

the

negative

polar

of

the

battery

shall

be

dis

‐

connected

so

that

to

ensure

the

generator

set

will

not

mistakenly

start.

4.2

Engine

Each

time

before

start

the

engine

!

Check

lubricant

oil

level

!

Check

coolant

level

!

Check

air

filter

indicator

!

Check

the

ventilation

of

radiator

and

ambient

environment

!

Check

engine’s

transmission

belt

!

Check

fuel

supply

status

Generator

sets

which

run

frequently

need

to

be

checked

one

time

every

6

to

8

hours.

Backup

generator

sets

need

to

be

checked

once

more

after

being

stopped.

Depends

on

the

new

generator

set’s

running

status,

when

it

is

necessary,

within

100

to

300

Hours,

following

actions

shall

be

taken:

!

Check

the

valve

clearance

!

Check

the

fuel

injector

For

each

0~50

hours

of

running

!

Discharge

the

water

remained

in

the

oil

‐

water

separator

!

Check

the

battery’s

electrolyte

level

(except

maintenance

free

battery)

For

each

50~600

hours

of

running

or

at

least

each

12

months

!

Change

lubricant

and

lubricant

filter

!

Because

the

quality

of

lubricant

oil,

sulfur

content

of

the

fuel,

and

lubricant

consumption

rate

of

each

engine

is

different,

the

interval

for

lubricant

oil

change

for

each

generator

set

will

be

different.

When

change

the

lubricant

oil,

at

the

same

time

oil

filter

needs

to

be

changed,

otherwise

the

change

of

oil

will

become

meaningless.

On

the

contrary,

if

the

lubricant

oil

remains

in

good

status,

we

can

filter

the

lubricant

much

better

by

change

the

oil

filter.

!

Change

fuel

filter,

clean

or

change

first

stage

fuel

filter

core,

oil

water

separator’s

core

(some

of

the

generator

sets

have),

check

and

organize

fuel

pipes

arrangement.

!

The

change

interval

of

above

fuel

filter

(core)

depends

on

the

quality

of

fuel

(if

it

contains

many

impurity),

the

fuel

adding

method

is

reasonable

or

not,

the

fuel

tank

is

cleaned

periodically

or

not

(contaminant

discharge).

Once

the

color

of

engine

exhaust

air

is

found

to

be

abnormal

and

the

output

power

decrease,

first

the

fuel

system

needs

to

be

checked.

For

each

400

hours

of

running

!

Check

and

adjust

the

transmission

belt

and

change

it

when

necessary

!

Check

and

clean

radiator

core

!

Discharge

deposit

in

the

fuel

tank

For

each

800

hours

of

running

!

Check

if

the

turbocharger

has

leakage

!

Check

if

the

air

inlet

pipes

has

leakage

For

each

1200

hours

of

running

!

Adjust

valve

clearance

For

each

2000

hours

of

running

or

at

least

24

months

!

Change

air

filter

(depend

on

ambient

air

quality,

decide

if

this

need

to

be

changed

earlier)

!

Change

coolant

and

coolant

filter

(some

generator

sets

have)

!

Thoroughly

clean

radiator

core

and

water

path

For

each

2400

hours

of

running

!

Check

fuel

injector

!

Thoroughly

check

and

clean

turbo

‐

charger

!

Comprehensively

check
