Description

[Detailed Description of the Invention] The oil supply device of this invention has the pump motor floating on the oil surface in the tank, so the suction water head of the bo/g can be small, and clean oil close to oil (2) can be pumped out. This method does not require installation space for the pump and motor on the ground; in other words, the pump motor is floated on the oil surface inside the tank, and its discharge pipe is connected to the oil supply hose outside the tank. be.

The 83F-JT has a pop motor on the ground and the suction pipe opens near the bottom (8) of the pontoon, so when the amount of oil in the pontoon decreases, the suction water head of the pontoon decreases. The fluid may become thinner, the amount of vomit may decrease, or it may become impossible to pump out. Also, for pump motor installation.
It makes i+ cheaper and has the disadvantage of sucking up sediment near the bottom of the tank.

The oil supply system of the present invention eliminates all of the above-mentioned disadvantages.To explain the drawings in detail, a float 2 is attached to a base 1, a pump 3, a motor 4, a flow meter 5, and an upper limit detection switch 6 are mounted on the base 1. A lower limit detection switch 7 is provided, which is floated on a curved surface inside the underground tank 8.

The pump 3 is connected to an above-ground oil supply pipe IO via a flow meter 5 and a hose 9, and a nozzle valve 12 is connected to the oil supply pipe 10 via a fuel supply hose 211.

The output signal line 22 of the flow meter 5 and the power supply wire 13 to the motor 4 are connected to a ground control device 14, and the output thereof is introduced into a flow rate indicator 15.

Refueling hose] A switch 17 that closes when the nozzle valve 12 is lowered to the old refueling position is installed in the hose lifting and lowering device 16 of 1.
In this case, the switch 17 is connected to the control device 14.

18, a manhole 20 for storing the base 1 etc. in the tank 8 is an alarm.

Switches 7, ]7 and motor 4 are connected in series, a switch 19 that moves in the opposite direction to switch 7 and an alarm 20 are connected in series, and switch 6 is connected in parallel with switch 19.

To explain the operation in detail, the switch 6 is open when it does not touch the ceiling surface of the tank 8, and the switch 7 is closed when it is not in contact with the bottom surface.

When refueling, lower the refueling hose 11, and when the nozzle valve 2 reaches the refueling position, the switch 17 closes, the motor 4 is energized, the pump 3 is operated, and the oil sucked up from the suction port 21 is Oil is supplied from the nozzle valve 12 using the flow meter 5, hose 9, oil supply pipe 10, and oil supply hose 11, and the oil supply area at the flow rate 2i't5 is displayed on the display meter 5.

As the oil level falls due to refueling, the base lowers and the lower limit familiarization switch 7 comes into contact with the bottom of the tank 8.
is opened, the motor 4 circuit is cut off, the rotation of the motor 4 is stopped, and the switch 19 is closed and the alarm 20 sounds to notify that the oil is running out.

When oil is refilled from the tank 8 ((when oil is refilled from the lorry, the switch 7 returns to its position and closes as the oil level rises, and after further refilling, the base 1 rises and the upper limit detection switch 6 reaches the ceiling of the tank 8. When contacted, the switch 6 closes and the alarm 20 sounds to notify that the oil is full.

Note that the flow meter 5 may be provided at a location outside the tank 8, for example, inside the hose processing device 16 or at a location close to the indicator 15.

In the refueling system of the present invention, the pump and motor are floated on the oil surface in the tank, and the discharge pipe thereof is connected to the refueling hose outside the tank, so that no space is required for installing the pump and motor on the ground.

Since the oil suction port moves up and down along with the base, the pump's suction head is small, and even liquids with high vapor pressure can be efficiently pumped out, and clean oil close to the oil level can always be pumped out. be.
