subscribers and guests of the channel
00:00:03
in the vastness of our educational
00:00:06
project,
00:00:07
issues of
00:00:10
consideration or review of
00:00:16
oil mist, a more detailed
00:00:20
theoretical part and the principle of operation
00:00:24
of this device, we have already talked about the
00:00:32
principles of operation, but
00:00:35
today we
00:00:36
will talk directly about practical
00:00:39
aspects and, of course, touch a little on
00:00:41
the theory, including already considering
00:00:45
the real one
00:00:46
oil mist detector and so on Let's
00:00:50
see
00:00:52
how the
00:00:55
determination of the so-called dangerous
00:00:58
Holy opacity of oil mist occurs
00:01:01
when you are
00:01:04
oil mist and got into the so-called
00:01:07
this is
00:01:11
where the analysis
00:01:16
or determination of opacity takes place. To do this, you
00:01:20
need to
00:01:21
pull up the mist with thoughts from
00:01:25
crankcase directly to the
00:01:28
measuring head; for this purpose,
00:01:32
compressed air is used, which
00:01:36
is connected to the
00:01:39
control air control system using a
00:01:42
pressure regulator; we set a lot;
00:01:46
you are asking, that is,
00:01:49
negative pressure, which
00:01:52
is 60 mm of water column;
00:01:55
about the principles and correctness of compiling
00:02:00
this pressure,
00:02:03
we are talking in webinar dedicated to the
00:02:06
features of the
00:02:07
operation and maintenance of an
00:02:11
oil mist detector. Well, let's
00:02:14
walk along the path of
00:02:18
oil mist from the crankcase to the
00:02:21
measuring head. So, first of all,
00:02:24
we use oils to get the mist into the so
00:02:27
-called Connection Box Connection Box,
00:02:30
this is exactly the box we have
00:02:34
oil mist enters, which
00:02:37
comes out of the crankcase
00:02:40
from the right
00:02:42
to the left side, we connect
00:02:45
tubes that are connected
00:02:48
directly to telephones
00:02:49
located on the engine crankcase; a
00:02:52
certain point that we must
00:02:54
consider before
00:02:57
directly traveling along the path of
00:03:00
studying oil mist is,
00:03:03
of course, an
00:03:05
LCD device that sucks
00:03:09
oil mist and engine crankcase
00:03:12
injector here in this part we have just the
00:03:16
same and here the gearbox is shown
00:03:19
on this side we come
00:03:22
control air already directly
00:03:26
air with oil mist
00:03:28
alabaster student fuel engines
00:03:31
returns back at the root if we are
00:03:34
talking about conventional conventional
00:03:36
engines when
00:03:38
reset outside the maps and so
00:03:41
in the end they could have gotten into the matte fog,
00:03:50
the oil mist gets inside, you go there,
00:03:55
then watch where the oil mist goes
00:04:01
into this hole,
00:04:03
then the oil mist under is convened. It goes along this
00:04:07
path and gets
00:04:12
through this flexible connection. Where is the
00:04:15
number 15
00:04:19
rubber seal located? a rubber
00:04:22
compensator which is necessary so
00:04:26
that during the process of operation the vibration
00:04:31
that comes from the engine and,
00:04:35
accordingly, the body of the
00:04:37
oil mist detector is rigidly
00:04:40
mounted on the engine so that this vibration is
00:04:44
not transmitted to the measuring head.
00:04:47
Head intends therefore it exists as a
00:04:49
Shock absorber and that is, 140 dampens
00:04:53
vibration and, accordingly, I due to the
00:04:56
fact that
00:04:57
the measuring head is not rigidly
00:04:59
fixed on the
00:05:02
island of the
00:05:05
oil mist doctor, accordingly, the
00:05:10
supply channels through which the
00:05:13
oil mist enters and then leaves must
00:05:17
be flexible, so the
00:05:19
ship mechanic on a regular basis
00:05:22
needs to monitor the condition of
00:05:25
these flexible connections,
00:05:28
you will leave Belous behind and it is necessary to
00:05:31
monitor the condition the Shock
00:05:34
absorber itself, that is, the damping diameters.
00:05:38
Let's look
00:05:41
directly at the measuring itself;
00:05:43
we open the plans for the measuring
00:05:46
head of people; we see the following picture of the
00:05:55
direct path of the
00:05:57
oil mist, which passes further
00:06:02
into this hole and directly
00:06:05
reaches the exit from the
00:06:09
oil mist detector
00:06:12
into the measuring chamber in
00:06:15
you understand the measuring head,
00:06:17
here the analysis of the opacity of the
00:06:21
oil mist takes place, how is it
00:06:24
carried out,
00:06:25
we have a meter, that is, an emitter on the
00:06:29
other side, we have a receiver,
00:06:32
considering the principle diagram of the operation of
00:06:35
oil mist on the left side,
00:06:40
that is, an
00:06:42
infrared LED emitting rays
00:06:45
of infrared light, respectively, on the
00:06:49
other side there is
00:06:51
a receiver photodiode, that is, the receiving
00:06:55
photodiode, in the event of an increase in the
00:06:57
opacity of the oil mist, that is, a
00:07:00
large number of oil particles
00:07:03
will be in the volume of crankcase
00:07:06
gases
00:07:08
through my greenhat, respectively, this
00:07:12
beam of infrared light will be reflected
00:07:15
from the oil particles and, accordingly, will not
00:07:18
reach the receiver photodiode of the receiving
00:07:21
photodiode and will be an
00:07:25
emergency activation trigger
00:07:27
warning alarm and
00:07:30
engine protection shutdown
00:07:34
operation principle of oil mist which
00:07:38
we have looked at in the circuit diagram,
00:07:41
let's look at the isotron 115
00:07:45
87 model, if we have oil mist
00:07:51
that stretches through the tax speaker, it does
00:07:56
not
00:08:01
reach the receiver, respectively, as
00:08:06
soon as it begins to be reflected in larger
00:08:10
quantities then, according to
00:08:14
the panel that determines
00:08:17
the opacity, the
00:08:19
concentration of
00:08:23
oil in the engine crankcase comes out when the
00:08:27
level of
00:08:29
5% of the
00:08:34
lower explosive limit is reached, which
00:08:36
is 2 mg per liter 2 mg of oil per 1
00:08:43
liter of air, a
00:08:44
warning signal is activated
00:08:47
from the cardboard
00:08:56
LED in red We need
00:09:00
air filters air filters
00:09:02
are needed for in order for the
00:09:04
supply air that enters
00:09:07
just from this part of this
00:09:10
disclosure to be installed tightly to the
00:09:14
body Here in this part We have a
00:09:18
small gap, this agreement guarantees the
00:09:21
entry of a
00:09:23
gentle charge of air
00:09:28
somehow there is labor and drilling to this film
00:09:32
that connects to the other
00:09:35
part of
00:09:38
the air gets to the second
00:09:42
air filter of
00:09:45
the air filter, the air is cleaned and
00:09:49
through the calibrated holes here in this
00:09:52
part the
00:09:56
calibrated hole
00:09:58
gets into mine. This
00:10:01
must be
00:10:06
ensured, let’s
00:10:12
say, so that the oil mist
00:10:18
drives
00:10:23
the receiver, that is, the emitter and the receiver,
00:10:27
so the
00:10:32
protective barrier of
00:10:36
fresh air is carefully examined by the operator
00:10:40
schematic diagram of the operation of the
00:10:42
oil mist detector We see that
00:10:46
the air filters are marked here
00:10:49
semperit bronze the filter on the left side
00:10:53
is installed Flow monitor on the right side the
00:10:56
temperature Sensor is installed and
00:10:58
in the middle the chamber into which a fresh
00:11:02
charge of air enters is called the
00:11:06
sherl0ck of the world of purge air
00:11:08
which just protects both the meter and
00:11:12
receiver in order not to cause
00:11:15
false signals emergency
00:11:19
warning alarm data the
00:11:21
air charge must be very clean
00:11:23
accordingly and the filter must be
00:11:26
maintained in proper condition
00:11:30
therefore the filter data is changed.
00:11:35
According to the instructions,
00:11:40
every three months the one
00:11:48
that has been analyzed gets further
00:11:53
comes out of the oil mist detector
00:11:58
let's go over the main ones errors that
00:12:01
may occur during the operation of the
00:12:04
oil mist director. So, if
00:12:07
our first LED starts blinking, this
00:12:12
indicates that we have
00:12:14
started oil mist, the second
00:12:17
LED indicates Electronics module
00:12:20
defects, that is, electronic
00:12:23
defective error 3. It tells us to
00:12:29
rest, that is, the
00:12:32
air flow is
00:12:34
faulty number four
00:12:40
the sensor that determines the opacity of the
00:12:44
oil mist is
00:12:45
faulty number five, this is a spark plug curve
00:12:50
sensitivity switch which
00:12:53
may also be faulty supply
00:12:56
Volga-Tour
00:12:58
voltage supplied
00:13:01
directly to
00:13:03
Tumanov that's why the cable is very
00:13:06
high number seven this is
00:13:11
right here we have a
00:13:14
Reset button installed if it is
00:13:19
faulty then our 7 LED lights up
00:13:23
and I will draw your attention
00:13:25
if we get an error then the LED
00:13:30
blinks red if we get
00:13:33
opacity then all the LEDs
00:13:37
below are lit constantly
00:13:42
showing the opacity level number
00:13:45
8 this is Electronics temperature to High
00:13:50
Five degrees that is more than 75 degrees
00:13:54
temperature of
00:13:57
electronic module
00:13:59
number nine electronic temperature
00:14:02
Tula If the temperature of the
00:14:05
electronic unit drops below 0°, we
00:14:09
also have an alarm signal,
00:14:13
respectively, the device gives an error
00:14:18
and
00:14:21
if
00:14:23
the temperature in the engine room is high
00:14:26
more than 70° or low below 0° We also
00:14:31
have a signal
00:14:33
which tells us about the error they gave number
00:14:38
12
00:14:47
number 13
00:14:51
just do we have some kind of
00:14:54
problem with these
00:14:57
calibrated holes if they are clogged then
00:15:00
we get error number 13
00:15:03
because there is no longer an air barrier and
00:15:09
oil mist gets on
00:15:13
the filters
00:15:15
accordingly
00:15:18
contaminating them Well, number 14 is the most
00:15:21
common error that
00:15:24
occurs when operating an
00:15:26
oil mist detector in Zaton, this is, of course,
00:15:31
that is,
00:15:35
if we
00:15:39
open the lid while the oil mist detector is working, it will
00:15:44
come out just the same, this is an error indicating
00:15:47
that the amount of negative
00:15:49
pressure has become insufficient in
00:15:53
order to
00:15:54
draw crankcase gases from
00:15:57
the engine to analyze the opacity of
00:16:01
oil mist, these are the main points
00:16:04
that today
00:16:07
I would like to consider in more detail using a
00:16:11
live example of an
00:16:12
oil mist detector and Let's
00:16:15
talk a little more about the services
00:16:18
that ship mechanics perform when
00:16:22
working with oil mist detectors and
00:16:26
so on in the process necessary as we
00:16:30
said to change the
00:16:35
baked bronze filter, then this is of course
00:16:39
a pity; calibrated holes;
00:16:45
emptiness is checked using a
00:16:47
special
00:16:52
calibrated cleaning tool;
00:16:57
checked for cleanliness; measured that it is not
00:17:00
clogged and that air quietly
00:17:03
sucks in and enters this chamber, preventing
00:17:06
contamination of the
00:17:13
emitter and the receiver directly; Let's
00:17:22
consider a few points in
00:17:23
today's issue
00:17:26
in the process of adjusting the room in the past.
00:17:30
We need to set a 60 mm water
00:17:33
column; this is done
00:17:36
using a YouTube-
00:17:37
shaped tube.
00:17:41
Next, we have a
00:17:43
special cleaning agent
00:17:50
on which
00:17:53
Madeline Hatter
00:17:56
cotton swabs are installed directly in order to clean the
00:18:02
emitter and
00:18:04
infrared light receiver And of course, this is a
00:18:09
special design for
00:18:11
installation and removal by the ranger; the
00:18:18
conveyor ring and sets of filter elements
00:18:23
are the filter elements that are
00:18:26
installed in
00:18:29
this; a
00:18:37
cylindrical type
00:18:40
filter element and two filter
00:18:44
elements are installed
00:18:47
directly on the side, the
00:18:50
so-called Fresh and Said
00:18:56
air side. which on a regular
00:19:00
basis are also serviced in this way, in
00:19:03
our today's episode we talked about the
00:19:07
features of the device
00:19:09
and
00:19:11
partially touched on the topic of
00:19:14
servicing oil mist detectors
00:19:18
in more detail and in detail in our 4-
00:19:22
hour course of the latest Ivan understood -
00:19:25
the director in which you will learn On which
00:19:29
engines an oil mist detector is installed
00:19:31
What is the cause of the
00:19:33
formation of oil mist in the engine
00:19:36
Consider the main points related to the
00:19:41
characteristics of the
00:19:43
oil Let's talk What is
00:19:46
Flashpoint What is PowerPoint
00:19:49
Of course, we will consider oil analysis and
00:19:53
then, using the
00:19:54
knowledge gained,
00:19:56
we will understand the principles of
00:19:58
determining opacity and the main
00:20:02
errors that arise during the
00:20:04
operation of a diesel engine associated with an
00:20:07
oil mist detector
00:20:10
Let's talk settings
00:20:13
about the maintenance of
00:20:18
siphons through which
00:20:21
oil mist is sucked in. I
00:20:25
hope you get this
00:20:29
webinar, this course is dedicated to the
00:20:32
director of oil mist. It will be
00:20:34
interesting, which is available on our
00:20:37
