Complete pipeline equipment• The pipeline equipment used are:a. Pipe cutter
Used
to cut the pipe so the pipe pieces to be flat and round and still no
cracks, it is important to note that when the pipe or diswage diflair
pipes are broken and the results are not good.
b. Capillary tube cutter
Used to cut the pipe that is small as the capillary tube. It is intended that the pipe is smaller still round and not clogged when cut
c. Pipe bending
Used to bend copper tubing to the pipe at the bend does not change
d. Tool for flaring and swaging
Used to connect the pipe with another pipe niple or by raising the tip of the pipe.
e. Tang Pricker
Vent pipe is used for the purpose of removing the refrigerant containing refrigerant. Tang is equipped with a hollow needle in a rubber sheath, when it clamped to the pipe, the needle will puncture the pipe.
f. Pierching tool
Used
to make holes in the engine cooling system pipe such that the
refrigerant in the system can be channeled into the storage tube
g. Pliers clamp
Used to clamp the pipe before the pipe containing refrigerant is cut
h. Brazing tool
Used to connect pipes or closing the leak. Pipe
to be jointed are usually heated above the temperature of filler
material, but still below the melting point of the pipe material
(between 600-800 ° C). Heating is carried out with the torch flame burning fuel with oxygen or airCapillary tube and FunctionsCapillary tube is a pipe at the water cooler good conditioner, refrigerator, etc.. This
capillary tube is the smallest pipe when compared with other pipes, for
a capillary tube or dispenser frezzer measuring 0.26 "s / d 0.31" while
for the capillary tube AC 1/2 s / d 2 pk is 0, 5 "s / d 0.7".
Damage
to the capillary tube in the engine coolant is usually caused due to
the capillary tube is deadlocked due to the incoming dirt and oil. Refrigerant
gas coming out of the compressor has become a pressurized gas then
flows through the pipes condenser (out door) and passes the screening
process is commonly called Drier strainer afterwards towards the
capillary tube. capillary length is needed on the engine coolant is 80-100 cm.
The
placement of the capillary tube is usually in rolls to save space by
using a capacitor used to avoid the mall penyek (in a circular roll). Capillary
tube serves as a means to lower the pressure, changing the shape of the
gas into liquid form and set the liquid refrigerant from the condenser
piping. Before
you refrigerant gas entering through the capillary tube should advance
through the tool is called Drien strainer filters which are mounted gas
from cooling the engine manufacturer. Stariner
is a function of the filter drier and apply the dust to be entered into
the capillary tube and into the pipe line to the indoor evaporator. This
capillary tube is not Sunnah if legal MANDATORY when pengggantian
compressor as a couple of times in the survey results did not change
when it will get stuck unless you want to work with the help of R11
FLUSHING.
Engine coolant leak RefrigranRefrigran leaks that occurred in the engine causing the engine cooling air is not cold anymore. The
characteristics of the engine coolant is leaking include: discharge of
oil from the surface of the pipe through which refrigran, there are
usually green rust in the pipes through which refrigran, terlihan bubble
when the pipe is pressurized and touched with soap foam. Here is a way to fix the engine coolant leaks:
Finding
the source of leakage by separating all the components of the engine
cooling (compressors, condensers, filters, expansion, evaporator, and
accumulator) then to the condenser and evaporator pairs nepel / light
bulb at the tip (using welding) and then the other end is closed /
dibuntu (using welding) ,
then plug the hose manifold (gauge pressure) at nepel red / yellow
light bulb later attach the hose to the tube refrigran (use refrigran
the same as the original cooler) and then close the faucet and open the
blue-red taps on the manifold and tap the tube until the pressure
refrigran 100
psi to 300 ps, and then close the tap on the manifold and tap the red
refrigran tube, after it touched all the parts with soap suds /
immersed in water such as tire until you find the leak, after the leak
see refrigran waste remaining in the condenser and evaporator and then
patched the leak with the appropriate material to the metal base material condenser & evaporator. And to filter, expansion, and accumulator should be replaced.When
finished filling open end kondenror & evaporator using pipe cutter
and then clean the condenser and evaporator by entering the R-11 (liquid
form so that when put to the condenser and evaporator tubes R-11 should
be reversed so that the R-11 can flow) through the manifold at a
position such
as pressure, then after the R-11 is inserted approximately 1 ounce tube
close the tap and then remove the R-11 hose that exist in the R-11 tube
to tube refrigran the same as the original, open the tap on the tube so
that the R-11 refrigran out together moisture
and dirt, do it over and over until it's clean after reconnect all the
parts like the beginning, after the later of the existing installed
napel / dop (nepel / dop location depending on the species) pairs of
hose manifold on nepel blue / yellow on the light bulb and hose vacuum
machine, close the faucet and open the red-blue faucet and turn the
engine manifold vacuum to the needle pointed to -30 psi and then tap the
blue cap and turn off the engine vacuum, and then move the blue hose to
the tube refrigran the same as the original blue and open the tap and
tap the tube until needle pointing normal contents of the cooler and then turn the engine coolant and do so until the normal charging refrigran. So how to fix a leak in the engine coolant.
Piping Connection kind:
Piping connections can be grouped as follows:A. Connection with the use of welding2. Connection by using screw
In
addition to the above there is a connection as well as a special
connection with the use of gluing (gluing) and pengkleman (for pipes and
pipe vibre plsatik glass). In the low-pressure pipe is generally refining and pipe below 2 "threaded connections that use alone.
Branch connection type:Connection type branch (branch connection) can be grouped as follows:A. Direct connection (stub in)2. Connection with the use of fittings (appliance connector)3. Connection with the use of flanges (flange-flange)Types
of branch connections can also be determined on the specifics of which
have been made prior to design or can be calculated based on the
calculation of the strength, needs, by not forgetting factor of
effectiveness. Is
itself a branch connection between the pipe with a pipe connection, eg
the connection between the header with the other branch does need a tool
other connective or can be connected directly, it depends on the needs
and strength calculations.
Diameter, thickness, Schedule:General
specifications can be seen on the ASTM (American Society of Testing
Materials). Where there is explained about the diameter, thickness and
pipe schedule. Outside Diameter (Outside Diameter), set at even thickness (thickness) is different for each schedule. In diameter (Inside Diameter), defined differently for each schedule. Nominal diameter of pipe diameter which is selected for installation or trade (commodity). Thickness
and the schedule, it is relate, this is because the thickness of the
pipe depending on the schedule than the pipe itself.Schedule pipe can be grouped as follows:A. Schedule 5, 10, 20, 30, 40, 60, 80, 100, 120, 160.2. Standard Schedule3. Schedule Extra strong (XS)4. Schedule double Extra Strong (XXS)5. Schedule specialThese differences are made to the schedule:A. Withstand internal pressure of the flow2. The strength of the material itself (Strength of material)3. Overcome the rust4. Overcome the brittleness of the pipe.To see the size of the diameter, thickness, and the schedule can be learned tablesSpecial tools: Special tools in this chapter only talks about sieve (strainer) and steam trap equipment (steam trap)Sieve (strainer)sieve (strainer) is useless as a tool which filters impurities either in the form of solid, liquid or gas. This
screening tool is used in pipelines to filter out impurities in the
stream so that will be processed aliaran or better process quality
results.These types of filter devices can be divided into:A. Type T. This type is used generally to expand the space and reduced the pressure in the pipeline2. Type Y3. Type of temporary4. Flat type
