Fuel system sealing test device above-mentioned also comprises a steam-water separator, links to each other with the pressurized air input port of described pneumatic gun.
At above-mentioned fuel system sealing test device, described inflation inlet comprises a charging connector and the oil filler sealing-plug that is arranged on the described charging connector.
The utility model has following remarkable result:
At first block the open to atmosphere snorkel of fuel tank with the snorkel sealing-plug, the zerk with device is tightly connected with the oil filler of fuel tank then, has so just formed the enclosure space of a fuel tank-oil inlet pipe-vapour filter-engine-scavenge pipe-fuel tank.Pressurized air is squeezed in this enclosure space by pneumatic gun after steam-water separator separates water vapor, and controls the gas flow of squeezing into by rain glass.When air pressure reached predetermined value, the closing control switch stopped to provide pressurized air, again by the atmospheric pressure value in the rain glass observation enclosure space.If atmospheric pressure value, then illustrates this fuel tank sealing system in the given time less than changing and can not reveal.
Description of drawings
Fig. 1 is the structural representation of a preferred embodiment of fuel system sealing test device.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail:
In preferred embodiment shown in Figure 1, this device mainly is made up of steam-water separator 1, pneumatic gun 2 and Inflation plug 3 three parts.In steam-water separator 1, pressurized air enters into wherein by the pressurized air input port 8 that is arranged on steam-water separator 17 tops, carries out carbonated drink separation, isolates the water vapor in the pressurized air.Enter in the pneumatic gun 2 through the conduit 51 that connects steam-water separator 1 then.
Pneumatic gun 2 is provided with a gauge tap 4 and is used for opening or cutting off the pressurized air that flows through pneumatic gun 2.Also connect a rain glass 6 in the gas outlet of pneumatic gun 2, be used to measure compressed-air actuated air pressure.Can decide according to top atmospheric pressure value during use compressed-air actuatedly opening or cut off (back will be done to explain more specifically).Pneumatic gun 6 also is connected with Inflation plug 3 by a conduit 52.The basic demand of Inflation plug 3 structures is to be tightly connected with the tank filler 71 of tested fuel system, thereby when measuring, can make fuel system be in the state of a sealing.Concrete structure for Inflation plug 3 can be varied, can use as long as reach above-mentioned requirements.In the present embodiment, Inflation plug 3 is made of a charging connector 31 and an oil filler sealing-plug 32 that is arranged on the charging connector 31, and the size of sealing plug 32 and the oil filler of fuel tank 71 adapt, thereby make fuel system be in sealing state.Pressurized air arrives charging connector 31 through conduit 52, and outputs in the fuel system by charging connector 31.
In the above-described embodiments, though include steam-water separator 1, should be appreciated that steam-water separator 1 is not is essential features.If the vapour content in the pressurized air is less,, can reach basic demand of the present utility model equally not using under steam-water separator 1 situation.
Explain the using method of proving installation of the present utility model below in conjunction with Fig. 1.As shown in Figure 1, fuel system generally includes fuel tank 72 and engine 77.Fuel tank 72 links to each other with engine 77 with scavenge pipe 74 by oil inlet pipe 73, also is provided with snorkel 75 and oil filler 71 on this fuel tank 72.During test, earlier in addition clog snorkel 75 on the fuel tank 72 with a snorkel sealing-plug 89, use proving installation of the present utility model then, Inflation plug on the proving installation 3 is inserted in the oil filler 71, oil filler sealing-plug 32 on the Inflation plug 3 closely contacts with the inwall of oil filler 71, can prevent the leakage of pressure gas.So just make fuel system form fuel tank 72-oil inlet pipe 73-air filter (in inside, so not shown)-enclosure space of engine 77-scavenge pipe 74-fuel tank 72, open the pneumatic gun 2 on the proving installation, pressure gas can fill into this enclosure space from charging connector 31.
In the above-described embodiments, the instrument that is used for stopping up snorkel 75 is a snorkel sealing-plug 8, as long as but be appreciated that the instrument that plays same effect all should be included in the protection domain of the present utility model such as clip etc.
Suppose that the measuring air pressure value is 0.3bar, it should be noted that this value just for convenience, conduct is not to restriction of the present utility model.Observe the atmospheric pressure value in the rain glass 6,, then continue retentive control switch 4 and be in the open site, provide pressurized air in loop if should be worth less than 0.3bar.In case when the atmospheric pressure value reading reaches 0.3bar, then gauge tap 4 is transferred to off-position, compressed-air actuated providing is provided.At this moment, the atmospheric pressure value in the whole loop is 0.3bar.In this embodiment, we equally also are for convenience being arranged on 5 minutes detection time, and conduct is not to restriction of the present utility model.After closing control switch 4, observe the reading on the rain glass 6 all the time and kept 5 minutes.If reading still remains on 0.3bar in 5 minutes, illustrate that then this loop does not have gas leakage, the fuel tank sealing system is qualified, otherwise this loop gas leakage then is described, and the fuel tank sealing system is defective.
Though the utility model is described with reference to current specific embodiment, but those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, should understand and wherein can make variations and modifications and do not break away from the utility model in a broad sense, so be not that conduct is to qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in the scope of the utility model claims variation, the distortion of the above embodiment.
