ISUZU aircraft refuel truck Use and Maintenance

Isuzu aircraft oil tanker truck ,it can refuel aircraft oil to the airplane

1. Preparation before use

（

1）Check whether the rear electrostatic drag zone is on the

ground and whether the equipment is in normal condition.

（

2）Insert the pole into the damp ground to prevent a fire from static

electricity.

（

3）Check that the clutch handle, PTO handle or control valve switch

is in the correct position and that the throttle is turned to the minimum.

Whether the ball valve handle is in the correct position。

（

4）Check the lubricating oil plane in the pump increase box,

and add gear oil when insufficient.

（

5）When there is no liquid in the oil pump, guide fluid should be

added to the pump body in advance. When the new truck is used for the

first time, guide fluid must be added to the pump to prevent no liquid

work, dry operation and damage to the pump body.

（

6）Check discharge line, discharge valve, transfer pipe are empty

and clean, ensure that all pipes are suitable for loading and unloading

media items.

（

7）If the liquid needs to be pumped, the rotating equipment should

be kept away from the tank truck to prevent entanglement. When the

liquid is pumped out, the pump should be stopped in time, and then close

the valve.

（

8）In case of emergency, the remote control switch of the

emergency cut-off valve should be closed in time to cut off.

（

9）If the pump is used to feed or feed from the manhole on the top

of the tank, a special person at the manhole on the top of the tank to

monitor the height of the liquid level in the tank, to prevent material

overflow, and ensure that there is space for expansion in the tank。

（10）Parking brake must be used before loading and unloading, and

wheels must be fixed with triangular wood.

（11）Set up warning marks before loading and unloading.

2.Loading

（1）Loading Directly from the manhole.

（

2）Pump In：Close the ball valve 1 And Open Ball valve2，And use

a wrench to close the four-position three-way valve B valve，Connect one

end of the feeding pipe to ball valve 2，The other end is connected to the

liquid reservoir，Hanging PTO and pump to work ，Can realize the pump

fuel into the tank。

Oil circuit: ball valve 2→ filter → oil pump → 4-position 3-way

valve .C-A→ sea valve.

（

3）When the oil depot fills the tank with fuel , the special oil

unloading valve(API) connector shall be used. Connect the oil unloading

valve, Vapor recovery interface and anti-overflow probe rod socket with

the filling equipment of the oil depot, open the sea valve (the other valves

are closed), and fill the oil into the tank through the operation of the oil

depot.

（

4）When the flow meter is optional, the pump feeding operation mode

（Note: the direction opposite to the pit of the three-way ball valve is

closed. Please note the pit position of the three-way ball valve) as shown

in the figure below：

3.Discharge

（1）Gravity self-discharging type: under the action of the gas path,

open the emergency cut-off valve (sea valve), and then by opening or

closing the straight-through ball valve 1 or 2, can achieve gravity.

（

2）Pump out discharging: close the straight-through ball valve 2

and open the straight-through ball valve 1, and use a wrench to close the

four-position three-way valve C valve, the transport pipe with one end of

the straight-through ball valve 1, the other end is connected with the

liquid storage, hanging PTO, pump work, can realize the outward pump

discharging.

3）When selecting flow meter, pump discharge operation mode

(note: the direction opposite to the pit of three way ball valve is closed,

please determine the pit position of three way ball valve) as shown in the

figure below：

4. Precautions for operation

（

1）All one-way valve handles are open along the line direction Use manual

and closed at 90 degrees from the line.

（

2）When working, you must first open the working valve before

hanging the PTO.

（

3）After the work is finished, the PTO must be closed first, and then

the working valve must be closed.

（

4）When the temperature is below zero, it is necessary to open the

feeding plug at the bottom of the oil pump to drain the residual liquid, so

as not to freeze the pump body.

（

5）Hang, take off the PTO, need idle speed when the barometer

reaches 6, hang, take off。

（

6）When loading and unloading with the pump, the cover of the

upper tank should be opened.

5. The use of FUEL DISPENSING MACHINE

第10页共 21 页Use manual

Before using the fuel dispensing machine , all valves are closed,

operation details please refer to the fuel dispensing machine manual.

The specific refueling process is as follows:

(1) four three point hit to position as shown in figure (if the oil pump

and the location of the filter is different from above, four three links point

to the location should be in contrast to the above), the tanks at the back of

the emergency cut-off valve (suction) remote emergency switch to cut off

the knob for pop-up state (press is closed, popup to open in the direction

shown by the arrow).

(2) Start the engine;

(3) first open the sea valve control switch;

(4) then open the switch of the PTO (the switch is on the left side of the

cab panel, the Sea valve must be opened first, the pump is prohibited to

idling);

(5) open the fuel dispensing machine power switch, open the tanker inlet

pipe on the small ball valve;

(6) Pick up the refueling gun, the nozzle of the gun into the oil tank or

barrel, start refueling;

(7) After refueling, put away the refueling gun and refueling pipe;

(8) Close the PTO, close the SEA valve, and turn off the engine.
