TYB explosion-proof electrical bar
The vessel explosion-proof electric
heating stick (hereafter refers to as electrical bar) is
hotly keeps warm specially for the storage tank and so on
vessel electricity partner designs the manufacture the
product.Since long ago in the storage tank the medium
partner keeps warm mainly is hotly uses the vapor or the hot
water takes the heat carrier the plate pot type heater.The
plate pot type heater existence accident rate is high,
overhaul maintenance difficulty, energy consumption big and
so on questions.For example the oil Tiandan well oil pot the
heat source limit, the partner keeps warm the question
always to puzzle the user community, the electrical bar is
precisely hotly develops in view of these questions.For many
years after national various oil fields place and so on
extraction factory, oil transfer pumping station, refinery,
fuel depot, marine petroleum platform, pharmaceutical
manufacturing plant uses, has confirmed this product
advanced technical performance and the good economic
efficiency.
Electrical bar characteristic
1st, the electrical bar is uses the
mineral which our company develops to insulate the (MI)
heating electric cable (or high performance alloy electric
heating tube) takes the heating element.
2nd, the electrical bar structure is solid, the bending
strength is high, exquisite, the seal, the explosion-proof,
conforms to the storage petroleum and the product various
patterns storage tank heating and the heat preservation
operation requirements.Explosion-proof rank d II B T1-T6.
3rd, the electrical bar gives off heat evenly, the surface
heat shoulders lowly, the work is reliable, the service life
is long.Does not have the reactive loss, the thermal
efficiency to be high, the operation overhaul is convenient,
daily does not need to maintain.
4th, the electrical bar can be good to the source oil and
the product medium corrosion resistance.
5th, the electrical bar contour geometry size may defer to
the user request production.

Matters needing
attention
When this product use should coordinate
the control system and the measuring instrument
Electrical bar installment
a, before the electrical bar installment
should inspect in detail whether complete, and with 500VMΩ
the table survey wiring column and the outer covering
dielectric resistance should ≥100MΩ, the ship be supposed to
be bigger than with the electrical bar 50MΩ.
b, the basis connection outer diameter opens the hole on the
shell of tank, and installs the electrical bar connection to
see Figure
c, meets
installs the electrical bar: Before the installment first
installs a bracket in the shell of tank, the bracket acts
according to on the shell of tank by the user the hole
highly and the electrical bar long manufacture and the
installment.Then the oil resistant asbestos rubber snare on
the electrical bar the electrical bar insertion shell of
tank connection, and with the bolt the electrical bar and
the connection fastens in together, and guarantees does not
infiltrate the oil.Sees Figure four
d, meets the
wire in the earth bolt place, meets the grounding to use
4mm2The above multi-stock copper grain line, and surveys the
earth resistance not to be bigger than 10Ω
e, the electrical bar sees Figure in oil pot arrangement
five, six:
f, TYBL (right
angle) guards against explosions the electrical bar
installment
The TYBL explosion-proof electrical bar from the oil pot the
manhole insertion, causes lower part the electrical bar the
level imposition at the oil pot base (Figure seven, Figure
eight), installs when the outer covering must earth, the
connecting box going beyond a line mouth installs guards
against explosions the hose.
Supplementary equipment and appendix selection
Include with the electrical bar necessary
equipment and the appendix: Electric heating control
cubicle, platinum thermal resistance temperature sensor,
float liquid controller.Above equipment, the appendix
necessary use, the realization constant temperature controls
the temperate lowest liquid protection automatically, and
has the manual automaticswitching.
1st, electrically controlled cabinet
The model divides into DK (on land (ship uses) with) and DKC
According to installs the position to divide into the
indoors and the outdoors
According to installs the way to divide into the hanging and
the console model
The model and the external dimensions see this factory DK
electric heating control cubicle instruction for use
2nd, temperature sensor
The temperature sensor matches which with the temperature
accommodometer selects WZP, its platinum thermal resistance
indexing number is Pt100, the pattern for inserts the stick,
outer diameter 16mm, the length takes L=800mm-1500mm
generally by the project actual designation.This factory
provides this survey resistance drive pipe for the user, the
drive pipe is 3/4 " blue gas tube.
3rd, fluid position controller
In order to prevent the electrical bar reveals the liquid
level in the movement to occur “parched”, necessary selects
the float fluid position controller to realize the low fluid
protection.When the liquid achieved when hypothesis low
fluid position, the automatic festival power failure source,
stops the electrical bar work, guarantees the safe
operation.
Necessary component installment
(1) control cubicle installment and
electrical wiring
The electric heating control cubicle is the
non-explosion-proof type, should install outside the
explosion-proof area (safety zone).Installs when the box
body should be vertical, meets the grounding to be supposed
reliable reliable.The console model needs the foot bolt to
fix the box body in the foundation.
According to the explosion-proof standard request, the power
cable and the control cable need to use the copper core
electric cable, its section should (see Table according to
the electrical bar power choice two).And wiring diagram
correct wiring which provides according to the factory.The
cut cable and the wiring column connection must use the
copper wire nose, does not permit with the stranded wire
direct pressure on the wiring column, the electric cable
must leave leeway suitably gives the allowance.
The electrical bar installs the electric cable to select the table
Note :
(1) actual selects the electric cable cross-sectional area
to be supposed again to examine according to the loss of
voltage.
(2) platinum thermal resistance installment
Because heats up the petroleum product fluidity is bad, this
process is an inhomogeneous temperature field, the platinum
thermal resistance and the electrical bar installment
relative position should choose can reflect the oil pot
interior oil quality real temperature.The suggestion ten the
position installment according to shown in Figure.
Installs the method:
The platinum thermal resistance installs in the steel
protective covering, the steel protective covering tube
welding meets on the oil pot wall, installs when inward
underneath inclines, has 15 degrees included angles with the
level (to see Figure 11), in the drive pipe will join the
right amount transformer oil, after the platinum thermal
resistance inserts the steel protective covering tube the
set screw to be tight.
(3) float fluid position controller installment
The float fluid position controller and the electrical bar
installment relative position sees Figure 12.Installs the
short saving water flat welding on the oil pot wall, the
float fluid position controller installs with the flange
connection in the short festival, between the flange must
front the asbestos rubber packing.Installs the short
festival to provide by the factory, the outer diameter size
is 90mm.(Sees Figure 13)
Tries to move
a, the inspection electrical bar and
necessary install is whether correct, is reliable
b, earths whether reliably, earth resistance whether
conforms to the requirement
c, surveys the outer covering and various wiring column
dielectric resistance with the 500V megameter should ≥10MΩ
d, inspection oil level whether is higher than the
electrical bar
e, qualified carries on after the inspection tries the power
transmission, and surveys the electric heating bandit phase
voltage and the electric current, completes the record,
observes continuously for 24 hours, if does not have
exceptionally then the normal work.
