Description
Technical field
The present invention relates to a kind of for example fuel in the fuel purifying case and with the fuel purification supply device of clean fuel supply motor effectively in automobile and building machinery etc.
Background technique
In automobile and building machinery etc., for example, if the fuel that will be mixed with foreign matter with regard to this supply engine, so motor will be easy to because of foreign matter impaired, thereby become the reason that causes engine failure.Therefore, in fuel supplying device, generally can on the fuel supply line of motor, the fuel filter that the foreign matter of sneaking in the fuel is removed be set with the fuel supply motor.For example, as shown in figure 10, in fuel supplying device 61 in the past, the fuel filter 64 that constitutes filtering mechanism is configured between fuel tank 62 and the motor 65.Driving fuel supply pump 63 is fuel sucking-off from fuel tank 62, and sends in the motor 65 by fuel filter 64.Thus, can be in fuel filter 64 filtering fuel and remove foreign matter, thereby can will remove the clean fuel supply engine 65 of foreign matter.
As a concrete example of this fuel supplying device, for example in Japan Patent special table 2002-506501 communique (patent documentation 1) a kind of fuel delivery means that fuel is flowed to the injection apparatus of internal-combustion engine (motor) from the fuel storage case is disclosed.In this patent documentation 1 disclosed fuel delivery means, in the container of fuel storage case, be provided with the supply unit of the motor part that comprises pump portion and this pump portion of driving.In addition, in this supply unit, surround it and dispose fuel filter peripherally.
Thus, the supply unit of patent documentation 1 can pass through driven pump portion, attracts to be housed in fuel in the container by fuel filter, and carries to internal-combustion engine.At this moment, fuel filter is caught the foreign matter of sneaking in the fuel, and fuel is filtered.Therefore, can the clean fuel IC engine supply of foreign matter will have been removed.
Yet the fuel quality that uses in automobile and the building machinery etc. is very high in Japan and American-European each developed country, and the amount of sneaking into the foreign matter in the fuel is less.Relative therewith, in the relatively poor country of the quality control of fuel, the fuel of sneaking into relatively large foreign matter also uses in many occasions.Therefore, in these areas, even dispose fuel filter as mentioned above on the fuel supply line of motor, foreign matter still is easy to accumulate in fuel filter, and filter can produce mesh at short notice and stop up.Thus, there are the following problems: must raise owing to change the frequency of maintenances such as filter, so cause efficiency of engine to descend, in addition, it is big that cost burden also becomes.
In addition, also there are the following problems: under the situation that the number of times that aforesaid filter is changed increases, safeguard required expense in order to reduce, the user does not use the regular fuel filter of manufacturer's appointment, and use inferior imitated filter at a low price, thereby form vicious circle.If use this inferior imitated filter, the foreign matter of sneaking into so in the fuel can't be removed fully.Therefore, the fuel of sneaking into foreign matter will be with regard to this supply engine etc., and the result causes the state of affairs that causes motor impaired.
On the other hand, for example open to disclose in the 2004-218567 communique (patent documentation 2) and a kind ofly turn to purpose with fuel supplying device small-sized and economize the fuel supplying device of configure fuel filter the Japan Patent spy.These patent documentation 2 disclosed fuel supplying devices comprise: be configured in the interior separation chamber of fuel tank, fuel is sucked from the separation chamber and fuel is produced member to the petrolift of motor and separation chamber's output and the rotating flow that makes fuel be rotated motion in the separation chamber.This rotating flow produces member utilization makes fuel be rotated motion in the separation chamber from the pressure of the fuel of petrolift output, thus can utilize this centrifugal force with foreign matter from the fuel centrifugation.
Adopt this fuel supplying device,, before with the fuel supply motor, produce member centrifugation fuel and foreign matter in the separation chamber, also can filter fuel by the use rotating flow even do not use fuel filter.Thus, for example,,, in addition, also can prevent because of using imitated filter to damage motor so, can prevent that also efficiency of engine from descending even in the relatively poor area of the quality control of fuel owing to do not need to change the such upkeep operation of filter.

Be connected with the outlet pipe 15 of above-mentioned filtering mechanism 4 on liquid tank 5, liquid tank 5 can store by filtering mechanism 4 and remove the clean fuel behind the foreign matter.In addition, in Fig. 1, liquid tank 5 forms with filtering mechanism 4, but present embodiment 1 is not limited thereto, and filtering mechanism 4 and liquid tank 5 also can be distinguished independent formation.
In addition, on this liquid tank 5,, detect the lower limit liquid level sensor 6b of the liquid level height of fuel when disposing the upper limit liquid level sensor 6a of the liquid level height that when the fuel that stores reaches upper limit amount, detects fuel and reducing to lower limit amount as level detection member 6.The upper limit amount of liquid tank 5 and lower limit amount can be carried out suitable setting according to performance of capacity, fuel pressure pump 3 and the fuel feed pump 9 of liquid tank 5 etc.
Fuel pressure pump driving component 7 comprises: the oil hydraulic circuit that oil pressure pump 18, switching solenoid valve 19 and the hydraulic motor 20 that is driven by operating oil tank 17, motor 8 constitutes.In addition, hydraulic motor 20 can come driving fuel pressure pump 3 by its output power is passed to fuel pressure pump 3.In this fuel pressure pump driving component 7, switching solenoid valve 19 links to each other with described level detection member 6, by the signal that receives from level detection member 6 switching solenoid valve 19 is opened and closed, and can control the driving of fuel pressure pump 3 and stops.
In addition, in present embodiment 1, described fuel pressure pump 3 is made of the oil pressure actuated pump that utilizes oil pressure actuated as mentioned above, but present embodiment is not limited thereto.The pressure pump 3 that acts as a fuel for example, also can use the motor-drive pump by electrical motor driven, or uses the exhaust gas drive pump that utilizes exhaust pressure that turbo machine is rotated to obtain driving force etc.
In addition, dispose the fuel filter 22 that the fuel to supply engine 8 finally filters between fuel feed pump 9 and the motor 8.In addition, as described below, this fuel filter 22 also can save.In addition, discharge side at the fuel of motor 8 and dispose the return pipeline 10 that the residual fuel that motor 8 is not consumed returns liquid tank 5.
In addition, in the fuel purification supply device 1 of present embodiment 1, send into flow fuel the liquid tank 5 more than or equal to flow for making, size of output flow in the fuel pressure pump 3 and cyclone separator 13 etc. is designed suitably by fuel feed pump 9 sucking-off from liquid tank 5 from filtering mechanism 4.
Below, the action of the embodiment's 1 of structure fuel purification supply device 1 describes to having as above.
At first, driving fuel pressure pump 3 and fuel feed pump 9 when motor 8 starts.Fuel pressure pump 3 is obtained power and is driven from the hydraulic motor 20 of fuel pressure pump driving component 7.Thus, fuel pressure pump 3 attracts to be housed in fuel in the fuel tank 2 by first supply pipeline 11, and with the flow of regulation to filtering mechanism 4 force feeds.
Fuel introducing port 14 from filtering mechanism 4 on the tangent direction of cylindrical part by fuel pressure pump 3 force feeds imports in the cyclone separator 13, and flows along the cylindrical part of cyclone separator 13 and the circumferential inner surface of conus portion.At this moment, in cyclone separator 13, be full of under the state of fuel,, can make fuel be rotated motion in the inside of cyclone separator 13 by fuel is imported from introducing port 14.Like this, fuel is rotated motion, thereby the foreign matter of sneaking in the fuel is moved because of the wall direction of centrifugal force to cyclone separator 13, while and rotate along internal face and to flow down.On the other hand, while the central part that fuel rotates to cyclone separator 13 move.Thus, can be in cyclone separator 13 centrifugation fuel and foreign matter.
At this moment, utilize fuel pressure pump 3 that the state of fuel with the optimum flow that can carry out centrifugation in cyclone separator 13 effectively imported.Thus, in cyclone separator 13, during by force feed, can make fuel under the certain flow rate of the best, be rotated motion all the time, can very effectively foreign matter be removed from fuel at fuel.
Then, as mentioned above, the clean fuel of being removed behind the foreign matter by centrifugation flows out from the outlet pipe 15 of the upper-end surface central part that is arranged on cyclone separator 13, is transported in the liquid tank 5.On the other hand, the foreign matter that flows down towards the bottom of cyclone separator 13 is discharged from exhaust port 16 with the fuel of a part, turns back in the fuel tank 2.In this case, in fuel tank 2, for example, the foreign matter of sneaking in the fuel is piled up in the bottom because of deadweight, takes out from fuel tank 2 by the foreign matter that will pile up, foreign matter can be discharged to the outside.
At this, for cyclone separator 13 that uses in the present embodiment 1 and following embodiment 2 cyclone separator 33, before the subtend filtering mechanism imports and the foreign matter the fuel after filtering mechanism flows out check and the relation between the rate of removing of separating of the particle diameter of having studied foreign matter and foreign matter.Its result is illustrated among Fig. 4.As mentioned above, the cyclone separator 13 of present embodiment 1 has the structure that foreign matter that centrifugation is gone out is discharged from exhaust port 16 with the fuel of a part.Therefore, for example, compare with the cyclone separator 33 that uses among the embodiment 2, it is outstanding that the foreign matter of cyclone separator 13 is removed ability, especially can remove fine foreign matters very effectively.Thus, in present embodiment 1, can will fully remove the very clean fuel storage of small foreign matter in liquid tank 5.
In addition, in present embodiment 1, fuel feed pump 9 is independent of fuel pressure pump 3 and drives when motor 8 starts.Thus, fuel feed pump 9 is irrelevant with the drive condition of fuel pressure pump 3, can attract to be stored in the clean fuel in the liquid tank 5, and stably supplies with to motor 8 with the certain flow of regulation by fuel filter 22.In addition, the fuel that motor 8 does not consume turns back in the liquid tank 5 by return pipeline 10 as residual fuel, and supply engine 8 once more circulates.
In the fuel purification supply device 1 of this present embodiment 1, as mentioned above, the flow fuel of supplying with liquid tanks 5 from filtering mechanism 4 is more than or equal to by the flow of fuel feed pump 9 from liquid tank 5 sucking-offs.Thus, as mentioned above, when fuel pressure pump 3 and fuel feed pump 9 both sides' pump drove, the fuel in the liquid tank 5 increased gradually.
Then, when the fuel in liquid tank 5 was increased to predefined upper limit amount, upper limit liquid level sensor 6a detected the liquid level of fuel.If this upper limit liquid level sensor 6a detects fuel and reaches upper limit amount,, stop the driving of fuel pressure pump 3 just the switching solenoid valve 19 of the fuel pressure pump driving component 7 that links to each other with upper limit liquid level sensor 6a can be closed so.At this moment, fuel feed pump 9 stops to have nothing to do with the driving of fuel pressure pump 3, continues flow with regulation to motor 8 fuelings.Thus, in liquid tank 5, stored fuel begins to reduce from upper limit amount gradually.Thus, can prevent that clean fuel from overflowing from liquid tank 5.
In addition, when the fuel in liquid tank 5 reduced to predefined lower limit amount, lower limit liquid level sensor 6b detected the liquid level of fuel.If this lower limit liquid level sensor 6b detects fuel and reduces to lower limit amount, just the switching solenoid valve 19 of fuel pressure pump driving component 7 can be opened once more so, driving fuel pressure pump 3.Thus, clean fuel is admitted to the liquid tank 5 from filtering mechanism 4, and fuel storage is in liquid tank 5, and storage volume increases gradually.Thus, can prevent reliably that generation runs out of gas in the liquid tank 5.
As mentioned above, by fuel is carried out force feed with the certain flow of regulation from fuel pressure pump 3, in filtering mechanism 4, during by force feed, centrifugation fuel and foreign matter are removed foreign matter fully from fuel very effectively at fuel.Thus, can in liquid tank 5, store very clean fuel.
In addition,, fuel feed pump 9 drives, so very clean fuel can be supplied with to motor 8 from liquid tank 5 with the flow all-the-time stable ground of regulation owing to being independent of fuel pressure pump 3.In addition,, the life-span of fuel filter 22 can be prolonged, in addition, configure fuel filter 22 can also be economized by supplying with very clean fuel from liquid tank 5.Thus, for example,,, in addition, also can prevent because of using imitated filter to damage motor even, also can prevent the low of efficiency of engine in the relatively poor area of fuel quality management owing to do not need to change the upkeep operation of filter.
In addition, as shown in Figure 1, in present embodiment 1, the return pipeline 10 that the residual fuel that motor 8 is not consumed is returned links to each other with liquid tank 5.The residual fuel that this motor 8 is discharged is a clean fuel of having been removed foreign matter by filtering mechanism 4.Thus, by this clean residual fuel is returned liquid tank 5, clean fuel is circulated between motor 8 and liquid tank 5.Thus, the driving of fuel pressure pump 3 can be reduced and the switching times that stops etc., cost performance can be expected to improve.In addition, for example, also this return pipeline 10 directly can be connected on the fuel tank 2, residual fuel is turned back in the fuel tank 2.In addition, in following embodiment 2～7, equally also return pipeline 10 directly can be connected on the fuel tank 2.
