GB/T 23292-2009Test methods for tractor fuel tank (English PDF)

2.2 Safety valve opening pressure test

Replace the fuel tank cap, fuel tank seal the other inlet and outlet, compressed air is applied to the fuel tank, the safety valve opens when the fuel tank measurement pressure.

2.3

Test vacuum intake valve is opened

Replace the fuel tank cap fuel tank sealed when other imports and exports, with a vacuum pump to extract air in the fuel tank, fuel measuring intake valve is opened

Tank vacuum.

2.4 vibration durability test

Simulation of the loading state of the fuel tank fixed to the vibration test stand, fuel tank was added to 85% of the rated capacity of the water, cover the fuel tank cap close

Seal all imports and exports, according to Table 1 will be vibration test.

Table 1 fuel tank vibration durability test requirements

Vibration acceleration/(m/s2) Vibration Frequency/Hz

Vibration Time/h

On the left, right front, rear

2.5 pressure resistance test metal fuel tank

Simulation of loading the fuel tank is fixed on the test bench, sealed the fuel tank of all imports and exports and filler, is applied to the fuel tank

80kPa compressed air pressure is maintained 10min.

2.6 Performance Test pressure plastic fuel tank

Simulation of loading the fuel tank is fixed on the test bench, sealed the fuel tank of all imports and exports and filler, is applied to the fuel tank

35kPa compressed air pressure is maintained 5h.

2.7 plastic fuel tank angle hammer impact test

2.7.1 diagonal hammer requirements

the side of an equilateral triangle, a square base, the quality of 15kg, vertex and edge fillet between half

3mm diameter steel impact body.

2.7.2

Analog loading fuel tank is fixed in the test apparatus, the rated capacity was added in the fuel tank of water and glycol mixture or other

When non-corrosive liquids low freezing point (freezing point temperature below -50 °C), the fuel tank until the temperature dropped to -40 °C ± 2 °C, with the angle to hammer 30J

Impact energy hit the fuel tank easy to damage the site. Each of the different parts of the test should use the new fuel tank samples. Easy to damage the fuel tank

According to the site to determine the shape of the fuel tank and fitting manner on the tractor.

2.8 plastic fuel tank heat resistance test

Simulation of loading the fuel tank is fixed in the test apparatus, the fuel tank was added to half of the rated capacity of 20 °C ± 2 °C of water, […]
