1.       Description

• Necessity of using aluminum fuel tank trailer:

1. The dead weight of the chassis is fixed under the condition of the customer, and the quality of the tank becomes the determining factor affecting the quality of the oil vehicle product preparation. In order to effectively reduce the quality of the reconditioning must first reduce the quality of the tank: and to improve the load quality as the destination to reduce the quality of the reconditioning, it can only change the material of the tank, with other lighter materials instead of carbon steel, such as aluminum alloy, non-metal, etc.

2. On the basis of the design technology and processing experience of mature products such as aluminum alloy aircraft refueling truck, it is necessary to change the tank body and accessories of conventional oil truck into aluminum alloy material. In addition, from the point of view of ensuring the quality of oil, aluminum alloy material is an ideal way

• Head of tanker trailer and anti-wave guard: 

1. According to the provisions of international GB18564, the welding of the head and the simplified body must be butt-welded, so the head type must be flanged, in order to improve its stiffness, the convex head is used, and its processing equipment is very mature.

2. Just add pressure drum equipment, such as hydraulic press, on the basis of ordinary flat head processing.

3. The existing aircraft refueling truck head is cylinder face, processing is difficult, not only the accuracy of the parts themselves is difficult to ensure, the consistency with the batch of parts is poor, and the simplified end face processing requirements are high, this form of head is more suitable for plug-in welding.

4. In order to improve its impact resistance and improve the stress condition of the weld bead, the welding of the wave guard plate is adopted by full welding. In addition, in order to reduce the impact of the liquid medium (oil) on the head, the amount of the manhole on the wave guard plate which is closely connected with the head is added in whole or in part. 

In order to improve the assembly and welding process of the wave guard plate and the simplified body, a layer of strengthening plate is added between the wave guard plate and the simplified body. 

Anti-wave guard plate, head material is the same as the simplified body, LF4, head wall thickness is equal to or greater than the simplified body, wave guard plate and strengthening plate wall thickness is reduced by 1mm on the basis of the simplified body.

• Left and right supports at the bottom of the tank:

1. about bearing (beam) still choose regular gasoline u-shaped form of vice beam structure, to improve the bearing stiffness of the section, after the simplified bearing outer riding bolt hole plate and stiffened plate full up into the saddle shape, ting is beneficial to increase the length of bearing weld, improve the stress state, around to increase the stability of the bearing, bearing of the riding bolt hole plate is measured reinforcement can be around in whole or in part is linked together, make two bearings as a whole.

• TANKER: Built-in aluminum tank volume 42,000L, tanker shape of section is gooseneck type.

• Manhole: It is installed on the top of the oil tank with built-in breathing and emergency exhaust functions, and can be installed on the manhole cover oil and gas recovery valve, oil measuring hole, anti-overflow rod, etc. In the process of filling oil, when the liquid level reaches the detection position, the sensing system will automatically alarm, so as to stop filling oil. Built-in breathing valve made in the process of oil tank internal pressure stable, and the external pressure balance, the dumping of prevent overflow design make the tanker keep sealed in the case of an accident, emergency exhaust system in the case of a tremendous rise of pressure tank, will open automatically, release the pressure of the tank, to prevent the accident, greatly improving the security of oil shipments.

• Functions and features:

  A: Different pressure parameters can be set according to needs to ensure reliable breathing function and emergency exhaust function.

  B: Breathing function When the pressure in the oil tank is 6~8KPa higher than the external pressure or 2~3KPa lower than the external pressure, the breathing valve will automatically open, so that the gas inside and outside the tank through, can reduce the large pressure difference between inside and outside, play a role in safety protection.When the difference between the internal pressure and the external pressure of the oil tank is -2~ 6kPa, the breathing valve is in the closed state to keep the appropriate pressure in the tank, so as to avoid the waste of volatile oil.

  C: In the event of an accident, when the tank car is dumped, the anti-overflow block in the breathing valve automatically seals the channel, to prevent the risk of oil leakage.

  D: Emergency ventilation When the oil tank car is in a high temperature environment, it can effectively release the pressure in the tank and prevent the oil tank from exploding. When the pressure in the tank exceeds the external pressure of 21~ 32kPa, the emergency exhaust device starts to work, and its maximum exhaust capacity reaches 7000m3/h, which can effectively prevent the explosion accident of the oil tank.

  E: Two-stage opening: release the pressure in the tank after the tank cover is all opened.

• Breath valve: Install breath valve on the cover of manhole.

  Breath valve can adjust the pressure inside of tank according to the air pressure inside of tank, and keep the balance with air pressure outside.

  The function of breath valve is to reduce the fuel transpiration inside of tank and avoid distortion caused by increased pressure.

  To make sure that pressure of the tank is in accordance with the air pressure, breathing valve was installed in the front of the tank.

  The fuel expend as heated, meanwhile the pressure will increase. When the pressure reach 8 Kpa, the up valve slice will open up (it is in close situation while high than 6 kpa).

  The fuel shrinks as cooled. Meanwhile the pressure will reduce, meanwhile the pressure will reduce. The lower slice will open up.

• Transmission system: The power transmitted from the truck transmission , via PTO, transmission shaft, and then to oil pump, to make sure it can work in 960r/min ( more details are referred to the manual)

• CONSTRUCITON: Fuel tank truck is made of chassis tank, oil pump, and ductwork and drive system. Besides device installed on oil transportation truck, refueling truck has oil pump system. Thus, oil in storage can be absorbed into tank, then transported and filled up into other devices. Refueling truck can finish the pump and delivery work conveniently through oil pump. So it can be widely used.

• Lower loading fuel system: The main devices of the aluminum oil tank truck are: manhole cover, oil and gas recovery valve, oil and gas recovery joint, submarine valve (emergency cut-off valve), oil discharge valve, anti-overflow sensor, etc. The product has the advantages of reasonable design, advanced technology, safety and reliability, energy saving and environmental protection.

• Seabed/bottom valve: also known as emergency cut-off valve, is installed at the bottom of the tank and used when loading and refueling. It is easy to operate, time-saving, safe and environmentally friendly. Pressure balance type submarine valve is used for multi – tank truck, can carry out separate loading and unloading of different tanks. The three-way design simplifies the pipeline, reduces the load, the operation is simple, safe and reliable. Pneumatic cut-off valve installed on the bottom of the tank car tanks, to refuel in the bottoms, the valve internal pressure is small, large flow, the valve flange has cut slot, accident in oil tank, due to the large fault trough in the unbearable momentum, car body line with tanks will automatically disconnect, and automatically for the plunger and durable spring will still keep seal, medium tank does not leak, so as to ensure the safety of the tank. When there is no air source or other reasons can not be opened, you can break the cylinder piston rod, manually open.

• Oil and gas recovery valve: It is a device for oil and gas recovery produced when loading and unloading oil. It can be directly installed on the top tank of the tank truck, or installed on the manhole cover. It can be opened mechanically through a push rod and the bottom of the tank, or controlled by the air source. The oil and gas recovery valve can recycle all the oil and gas generated by oil volatilization during loading and unloading to the oil tank in the reservoir area to avoid the leakage of oil and gas. The oil and gas can be condensed and reused through other oil and gas recovery devices, so as to achieve the purpose of energy saving and environmental protection. Functions and features: A: When tank truck tank is filled, oil and gas recovery valve is opened, and the rising liquid level pushes the oil and gas upward, through a series of oil and gas recovery system, and returns to the tank in the reservoir area. B: When the tank truck unloading oil, the recovery valve allows the recovered gas to enter the tank of the tank truck. In systems without oil and gas recovery facilities, air is allowed into tank truck tanks. C: High sealing, to ensure the safety of tanker transportation. D: Reasonable valve body design to ensure high efficiency of oil and gas recovery.

• Oil and gas recovery system: It is composed of fire-retardant breathing valve, pipeline flame arrestor, three-way float ball valve, oil and gas recovery joint, oil and gas recovery quick joint, etc. It forms a closed circulation system with oil and gas recovery system of tank car, which can effectively recycle and reuse oil and gas generated in the process of filling oil and gas in oil filling station and avoid oil and gas diffusion.

• Anti-overflow probe rod: electronic anti-overflow sensor is widely used in all kinds of containers in the closed filling liquid, in order to prevent the liquid full leakage and advance alarm of a safety device, it is installed on the top of the container tank manhole cover, when the oil level reaches the warning limit, the sensor will automatically alarm off the brake.
