LDY Fluid state electrical heater
The fluid
state electric heater may classify the explosion-proof and
must guard against explosions two kinds, it is carries on
the heating through the forced convection way to the
medium.Namely the medium from leads the inflow through the
heating cavity, after the process heating flows out from
another.Mainly is suitable for the crude oil, the refined
oil, the vegetable oil, the asphalt, the water, the gas and
so on many kinds of medium heating widely applies in the
petroleum, chemical, the fuel depot, the metallurgy, the
power plant, the sea petroleum platform, the spinning and
weaving and so on.
Model meaning
Technical performance and characteristic
★ This product heating element
uses the mineral to insulate the (MI) heating electric cable
(or high performance alloy electric heating tube), its shape
fineness ratio belongs linearly, the heat conduction
performance is good, gives off heat between the core body
and the metal protective covering the temperature difference
is very small.May act according to the craft special
request, designs the MI heating electric cable heating
element precisely the surface heat load density, gives off
heat under the total output premise in the guarantee, is
heated up the medium not to be able to coke the
carbonization.It has solved the traditional tubular electric
heater long-standing carbon deposition, the cartridge
igniter, the short life malpractice.The heating element may
act according to the user the use place, divides into the
copper protective covering and the stainless steel
protective covering.
★ The electric heater outer
covering becomes by the seamless steel pipe and the flange
welding, overall construction close solid, the bearing
pressure sealing property is good, use security, working
pressure 2.5MPa-6.4MPa.
★ The component connection and
the electrical connection conforms to the explosion-proof
requirement, the explosion-proof rank is d the IIBT3 level.
★ In the electric heater is
loaded with the temperature sensor superheat, the
examination oil quality temperature, the oil quality, the
heating element surface temperature.The current capacity
block system may choose, when the medium is not mobile,
electric heater automatic stop heating.
★ Daily does not need to
maintain, installment simple, the overhaul is convenient.
★ The product usability and
contingency nature, may the different use and the special
request which proposed according to the user design each
kind of non-standard type the electric heater.
Installment
1st, the horizontal-type electric heater installs the way
for the level.The export should be vertical upwardly, before
the import, after the exportation requests to have 0.3 meter
above straight length of pipe, and installs the by-pass
pipeline, adapts the electric heater inspection work and the
seasonal movement need.
2nd, before the electric heater installment should use the
500V megameter to examine the host binding clamp and the
outer covering dielectric resistance, the insulation should
≥1.5MΩ, the ship uses electricity the heater dielectric
resistance to be supposed ≥10MΩ, and checker body and
various parts whether there is damage phenomenon.
3rd, this factory necessary production control cubicle for
must guards against explosions the equipment, should install
(safety zone) installs when the explosion-proof area should
carry on the comprehensive inspection and the correct
wiring.
4th, the telegram dares the wiring to have to conform to the
explosion-proof requirement, the electric cable must select
the copper core and use the wiring nose connection.
5th, the electric heater is equipped with the
special-purpose earth bolt, the user should meet the
grounding to be possible the approach grafting on this bolt,
meets the grounding to be supposed to use 4mm2The
above multi-stock copper wire, the earth resistance should
not big 4Ω.
6th, the wiring finished, must spread the industry petroleum
jelly guarantee seal outside the connecting box joint to be
complete.
Debugging
1st, tries before the movement to be supposed to inspect the
system situation once more, inspects the supply voltage and
the data plate whether tallies.
2nd, according to the temperature accommodometer instruction
for use stipulation, establishes each temperature definite
value reasonably according to the technological requirement.
3rd, the electric heater superheat protector according to
the explosion-proof specified temperature quota, has not
needed to adjust.
4th, tries when the movement first opens carries on the
pipeline valve, closes the bypass valve, drains away in the
heater the air, after the medium fill, the electric heater
only then starts.
Warning: Forbids the electric
heater to be parched absolutely!
5th, should correctly operate and record when the movement
the voltage, the electric current, the temperature according
to the equipment stochastic blueprint document operation
explanation and so on each related data, tries to move for
24 hours not to have the unusual situation only then to
arrange the official movement.
Movement
1st, should persist regularly carries on
to the equipment and the line patrols the inspection, the
enhancement maintenance maintenance, should pay attention to
the inspection contact empty especially, the post, whether
there is the attachment and so on meets the superheat
phenomenon.
2nd, every year should decide the seasonal cropping
electricity parameter the calibration and the checkup.
3rd, every year verifies a time thermal sensor and the
temperature control measuring appliance, the guarantee size
is accurate.
4th, stops using the postscript for a long time with or
migrates the place of use, should strict 1, 2 content
execution.。
