It is standby.Therefore, structure large-scale, management cost can be caused to rise.Moreover, the structure heated to fuel oil holding vessel easily by
The influence of the outer temperature of influence, periphery to the ocean temperature for being transmitted to fuel oil holding vessel, thermal losses may become larger.
On the other hand, if the viscosity of fuel oil rises, the load variations of shifting pump are applied to, the variation is sometimes to moving
The driving source of pump is sent to generate harmful effect.Shifting pump is driven by a motor, and motor, which is applied in, can obtain preset rotating speed and torque
Driving current.But if rotating speed is reduced when viscosity rises, driving current is improved so that its rotating speed is restored to original shape
State.In the case of even if improve driving current rotating speed without restoring, driving current is also further improved, as a result has and causes
The danger of the accidents such as the scaling loss of motor.
If the accident of motor occurs, fuel oil can not be transferred, becomes the fuel that cannot improve in fuel oil holding vessel
The reason of viscosity of oil, the transfer efficiency of fuel oil reduce or cannot carry out temperature management.

Heat refers to, by the way that the fuel oil after being heated is made to be mixed with the fuel oil not heated, and improves the fuel oil not heated
Temperature.
Fuel oil transfer device 1 can select that the viscosity of fuel oil is relatively low and flow resistance it is smaller in the case of perform it is logical
Normal operation mode and above-mentioned viscosity is higher and flow resistance it is increased in the case of any one of the heating operation mode that performs.It is logical
Normal operation mode is the shifting pump 6 operated according to the working condition of level transducer 9 and carries out into fuel oil holding vessel 2
Fuel oil supply flowing down the pattern for pumping 11 alternate-runnings and being recycled fuel oil.Heating operation mode is to force to stop
Only on the basis of shifting pump 6, the fuel oil being trapped in the suction side of shifting pump 6 is heated and by returning to fuel oil
The pattern that the fuel oil of holding vessel 2 also heats the fuel oil in fuel oil holding vessel 2.Preferably, heating fortune is performed
Rotary-die type does not make the increased value of flow resistance until the viscosity of fuel oil being trapped in 6 side of shifting pump reaches.
As for performing the condition of heating operation mode, parameter particularized below is used.
That is, parameter at least uses the duration of runs of the temperature of the fuel oil sucked by shifting pump 6, pressure and shifting pump 6.It closes
In the duration of runs of shifting pump 6, as described above, the duration of runs, shifting pump 6 until working referring to level transducer 9 are certainly
The timing time for the timer that body has.If the whole of these each parameters or any one or more are predetermined with needing to heat
It is consistent, then perform heating operation mode.
Hereinafter, about for performing the structure of the operation mode and effect, illustrated using Fig. 3.
Shifting pump 6 is controlled by control unit 20 shown in Fig. 3 and flows down the operating condition of pump 11.

In the operation panel of the input requirements such as fuel consumption and back amount, reference numeral 16 is timer.
Timer 16 from the time point that shifting pump 6 starts running to by level transducer 9 for example to detecting liquid level
Required time is measured.Therefore, to shifting pump 6 operates while level transducer 9 detect liquid level until operating when
Between when being more than necessary above, can be judged as that viscosity is higher and flow resistance is larger.In other words, in the duration of runs of shifting pump 6
During more than more than necessity, it can be judged as shape higher in the viscosity of fuel oil for flowing through shifting pump 6 and that flow resistance is larger
State.Shifting pump 6 itself has the timer measured to the duration of runs sometimes.In this case, it is operated in shifting pump 6 to certainly
When in the timer of body more than the preset duration of runs, it can be judged as that the viscosity in fuel oil is higher and flow resistance
Larger state.
In addition, as judging monitoring pair that the viscosity of fuel oil is the predetermined condition for making the increased viscosity of flow resistance
Can be object for the driving current value of the motor of the driving source of shifting pump 6 as project.
Driving current value in order to obtain the rotating speed of preset motor, torque and determine, but rotating speed, torque change situation
Under, changed in a manner of reverting to original state, particularly in the case where rotating speed, torque reduce, driving current value rises.
Then, situation about being risen by monitoring driving current value can be judged as that the viscosity of fuel oil rises, can carry out operational mode
The switching of formula.
By the usual operation mode that control unit 20 selects fuel oil feelings of the viscosity not make the increased value of flow resistance
Fuel oil is recycled under condition while keeping the temperature.According to the operation mode, the fuel for inhibiting to store in fuel oil holding vessel 2 is maintained
The state that the temperature of oil reduces and prevents viscosity from increasing.
Control unit 20 during usual operation mode monitors the temperature, pressure, shifting pump 6 for the fuel oil for importeding into shifting pump 6
The duration of runs and the driving current value applied to the motor of the driving source as shifting pump 6 variation.
These supervision object projects are for example in the case where producing 4 kinds of situations particularized below, as the viscous of fuel oil
Degree changes, particularly is used as the predetermined condition for being judged as viscosity rising.
(1) viscosity for reaching fuel oil rises and the situation below the increased temperature of flow resistance.
(2) pressure change of the fuel oil introduction side of shifting pump 6 is inclined to the situation of generation state for evacuation.
(3) situation of the duration of runs extensionization of the shifting pump 6 until level transducer 9 works.
(4) situation that the driving current value opposite with the driving source of shifting pump 6 rises.
Being unsatisfactory for these predetermined conditions usual operational mode is performed without generating in the case that the viscosity of fuel oil rises
Formula.
When performing usual operation mode, alternate repetition carries out sucking combustion from fuel oil holding vessel 2 to fuel oil settling tank 3
Expect the cycle of oil and fuel oil settling tank 3 and/or the fuel oil of the part in fuel oil working tank 4 is made to be stored towards fuel oil
The cycle that tank 2 flows down.Wherein, even cycle midway, the work also according to level transducer 9 stops shifting pump 6.Perform the fortune
The operating condition of each pump 6,11 during rotary-die type is shown on operation panel 15.
When continuing the monitoring of above-mentioned supervision object project and performing usual operation mode, according to the supervision object project
Under the whole of derived predetermined condition, any one or multiple unanimous circumstances, heating operating is switched to from usual operation mode
Pattern.
It under heating operation mode, forces to stop shifting pump 6, makes to flow down 11 operating of pump, the fuel oil after being heated flows into
To fuel oil holding vessel 2.At this point, fuel oil after being heated on one side via the fuel oil introduction side of shifting pump 6 and in the position
The fuel oil mixing being trapped is put, is flowed on one side towards fuel oil holding vessel 2.Fuel oil for example with opposite filter (in Fig. 2
In be by component that reference numeral FT is represented) when flowing in a manner of adverse current, play the function of the blocking of elimination filter.
In control unit 20, temperature, pressure can be directly by sensor monitorings, but about to making in supervision object project
The duration of runs of shifting pump 6 until detecting liquid level with level transducer 9, state based on shown in Fig. 4 determine whether to perform
Heating operation mode.
In Fig. 4, the longitudinal axis represents the amount (amount that level transducer 9 works) of fuel oil, and horizontal axis represents the time.
In the figure, it increases with the viscosity of fuel oil, is passed in the case where shifting pump 6 to be set as to fixed output to level
Time until sensor 9 works is elongated.
Therefore, to be directed in fuel oil settling tank 3 until level transducer 9 works to the relatively low fuel oil of viscosity
Time (in Fig. 4, by time that reference numeral T is represented) on the basis of and than the time lengthening situation (in Fig. 4, with attached
The time that icon note T1 is represented) under, it can be judged as that the viscosity of fuel oil is high.In addition, itself has timer in shifting pump 6
In the case of, the setting time and the practical duration of runs of timer are compared, in the feelings of practical duration of runs extensionization
It can be judged as that the viscosity of fuel oil is high under condition.
If under all or part of predetermined condition according to derived from supervision object project or multiple unanimous circumstances
Heating operation mode is selected, then the fuel oil after being heated is conveyed towards fuel oil holding vessel 2.It is not only stored up as a result, with fuel oil
The fuel oil deposited in tank 2 directly mixes, and is also mixed with the fuel oil being trapped in the suction side of shifting pump 6, can make fuel oil
Temperature rise.As a result, due to heating fuel oil in the oil circuit before fuel oil is sucked by shifting pump 6, therefore, it is possible to
Ensure that the viscosity for being flowed into the fuel oil of shifting pump 6 reduces.
Drive in the motor as the temperature of supervision object project, pressure, the duration of runs of shifting pump and shifting pump
The variation of streaming current value reach eliminate viscosity rise condition and with predetermined condition it is inconsistent in the case of, revert to usual operating
Pattern.
According to the fuel oil transfer device 1 of above embodiment, when forcing to stop shifting pump 6, using in fuel oil
The fuel oil that settling tank 3 is heated can not only heat the fuel oil sucked by shifting pump 6, additionally it is possible to heat fuel oil storage
Fuel in tank 2.
The result is that the driving load of inhibition shifting pump 6 increases and heat the fuel oil of the entrance side of shifting pump 6, reduces
Flow resistance is lowered due to almost forcing, during can shortening stopping.
Industrial applicibility
The present invention can utilize the fuel oil that the pressure of shifting pump stops while heating is sucked by shifting pump and fuel oil to store up
Deposit both fuel oil in tank.It is different from the situation of the fuel oil using the shifting pump transfer increased viscosity of flow resistance as a result,
In the load reduction that can be carried out rapidly to shifting pump and only can just be shortened up to shifting pump by flowing down the driving of pump
The aspect practicability for the time restarted is high.
