Description

Detailed Description of the Invention [Industrial Field of Application] The present invention provides a metering system in which a pump discharge pipe is branched into a plurality of branch pipes, and the branch pipes are connected to a flow meter and a nozzle via a hose. This invention relates to an improvement in a refueling device installed in a case.

[Prior Art] A variety of such refueling devices have been proposed in response to the trend towards mass sales at refueling stations such as gas stations, with refueling points being common.

By the way, in this type of oil supply device, the pump has conventionally been disposed below the motor in order to prevent leaked oil from entering the motor. As a result, the length of the pump's suction pipe (e.g., flexible pipe) has become shorter, and therefore there is less margin, and if the position of the suction pipe and the piping from the underground tank are misaligned, it is difficult to adjust the connection with the connecting part. .

In addition, in oil supply systems that do not branch the pump discharge pipe, the width of the case is relatively narrow, while in oil supply systems in which the pump discharge pipe is branched into multiple branch pipes, the width of the case is necessarily wide, and the suction pipes of both pumps are relatively narrow. The position of is slightly shifted. the result,
When replacing a lubrication system that does not have a branched pump discharge pipe with a lubrication system that has a branched pump discharge pipe in order to improve lubrication efficiency, if the suction pipe leading to the pump is not bent inside the case, the inside of the island will be vertically damaged. Bending the suction pipe in a narrow case without connection to the piping from the ascending tank is a waste of space and results in a loss of flow.

On the other hand, moving the piping that rises inside the island
Concrete work must be done on the ground, which is troublesome and costly.

[Object of the Invention] Therefore, an object of the present invention is to provide a fuel supply device that facilitates connection adjustment between the suction pipe of a pump and the connecting portion of the pipe from the underground tank.

[Structure of the Invention] The oil supply device according to the present invention branches a pump discharge pipe into a plurality of branch pipes, and a plurality of metering devices in which the branch pipes are connected to a flowmeter and a nozzle via a hose are provided in one case. It is.

[Operations and Effects of the Invention] Therefore, since the pump is placed above the motor, the suction pipe of the pump can be made longer than in the conventional device to provide more room and can be brought to the center of the case.As a result, the inside of the island can be The connecting portion can be located at a position that is reasonably aligned with the piping from the rising tank, making connection adjustment easy.

Furthermore, oil leakage from the pump can be sufficiently prevented by improved sealing technology, and there is no problem.

Therefore, when replacing the pump discharge pipe with an oil supply device having a plurality of branch pipes in order to improve the efficiency of the oil supply operation, the installation work is extremely easy.

[Preferred Embodiment] When carrying out the present invention, it is preferable to arrange the pump in the center of the case and above the motor, and the suction pipe of the pump is provided in the center of the case, and two flowmeters each. are preferably located vertically on both sides of the case. In this way, the arrangement of equipment and piping within the case can be rationalized, and the thickness of the case can be reduced and the height can be increased to save space.

[Actually 1 example The present invention will be described in detail below with reference to the drawings.

In FIG. 1 and FIG. 2, the case of the refueling device includes a lower case C1 and an upper case C above the lower case C1.
2 and a top case C3.

The lower case C1 includes 2M'l pumps P1 and P, which will be described later.
2. Motor Ml, M2.4 flowmeters Wl, W2,
Control of W3, W4 and each weighing device [1 device $1, S2
, S3, and S4 are built-in.

In the lower center of the front A and rear B of the upper case C2,
There is an operation panel 2 equipped with a card reader 3 for reading refueling card information, a keyboard 4 for presetting and unit price setting, and a sub-display 5, a nozzle hook 6 on the left and right sides of the operation panel 2, and a nozzle hook 6 on the outside of the nozzle hook. Fuel card holder 7 and
A fuel filler cap holder 8 is provided at the outer lower part of the nozzle hook, and an emergency stop button 9 is provided above the card holder.

At the center of the upper part, there is a shared main display 11 and refueling indicator lamps 12 on the left and right sides of the main display 11 to indicate that refueling is in progress.
and is provided.

The front surface A and the rear surface B of the top case C3 each indicate the type of oil (regular and high-octane gasoline in the illustrated example).
A display panel 13 is provided to display the information, and display panels 14 are provided on the left and right sides to display the surface in which refueling is being performed. The nozzle hooks 6 on the front and rear surfaces A1B are equipped with oil supply nozzles N1, N2 ( for front A), N3. H4 (rear B
) is applied.

In FIG. 3, the case is mounted on a bed 15 that is fixed to an island (not shown) with anchor poles 1-17. Motors M1 and M2 are arranged on the left and right sides of the bottom near the center of the lower case C1. Motor Ml
, M2 are arranged with pumps P1 and P2, and above the pumps P1 and P2 are control devices @S1, S2, S3, S
4 is placed. The flexible suction pipes 18a and 118b of the pumps Pi and P2 extend downward from the center line side of the case C1 of the motor M1.2 and are connected to a pipe connection from an underground tank (not shown) in which regular gasoline and high-octane gasoline are stored. ing. The discharge pipe 32 of the pump P1 is branched into two branch pipes, each of which is connected to a flow meter W1 and W2. The flow meter W is connected to the oil supply nozzle N1 via a pipe 19 and a hose H1. A solenoid valve 20a is interposed in the middle of the pipe 19.

Flowmeter W2 is similarly connected to oil supply nozzle N3 via electromagnetic valve 20b. Similarly to pump P1b, it is connected to oil supply nozzles N2 and N4 via flowmeters W3 and W4 and electromagnetic valve 20C120d. When the refueling nozzle N1 is removed from the nozzle hook 6, the solenoid valve 20 of this refueling nozzle is opened, and the other refueling nozzle N2 is interlocked. In addition, K is a peak meter of each flowmeter, and 21 is a lighting device that illuminates the display panel 13 (FIG. 1) from inside.

In this way, since the pump P is arranged above the motor M, the advantage of the flexible suction pipe 18 is that it is much wider and longer than when the pump is arranged below the motor M as in the conventional device. As a result, the flexible suction pipe 1
8 and the connection part of the pipe from the underground tank can be easily adjusted. In addition, the suction flexible pipe 1 of the pump P
8 is installed in the center of the lower case C1, and the flowmeters W are placed on both sides of the lower case C1, so that the equipment arrangement and piping inside the lower case C1 can be rationalized, and the thickness of the lower case C1 can be reduced. , the height of case C can be increased to save space.

``Summary'' As explained above, according to the present invention, the pump is disposed above the motor, so the length of the pump suction pipe is lengthened to provide a margin, and as a result, the water from the suction pipe and the underground tank is increased. Connection adjustment with the connecting portion of the piping can be facilitated.
