Technical field
The utility model relates to the checkout equipment of a kind of aircraft with fuel oil, is specifically related to a kind of vacuum type chemistry and surveys the water device.
Background technology
" control of civil aviation fuel mass and running program " (MH/T 6020-2006) regulation, fuel truck to before the operation of aircraft filling jet fuel, need be carried out the oil quality inspection item that chemistry is surveyed water at every turn.
For the oil quality of being annotated is checked, existing fuel truck for aircraft filling jet fuel all is equipped with closed circuit sampler 10, as shown in Figure 1.
When surveying water, open the fillup valve 11 of closed circuit sampler 10, jet fuel injects closed circuit sampler 10 by filtrator 12 pipeline of flowing through, and after jet fuel injects some, closes the fillup valve 11 of closed circuit sampler 10;
Chemical water finder is enclosed within on the syringe, and the syringe that will be connected with chemical water finder again embeds in the sampling groove of closed circuit sampler 10, extracts the 5ml oil sample, the color of observing chemical water finder test paper then, the content of undissolved water in the judgement jet fuel.
This survey water method has the following disadvantages:
1, the sampling groove of closed circuit sampler 10 is upwards offered, and rainwater splashes into easily and gathers, and distortion as a result occurs when surveying water, easily causes supervisory personnel's misunderstanding.
2, the sampling groove of closed circuit sampler 10 is installed on the injection pipeline of closed circuit sampler 10, and the oil sample that is extracted when surveying water fails fully to stir, and judges that the representativeness of undissolved water is not enough in the jet fuel.
3, the position of the sampling groove of closed circuit sampler 10 (groove that promptly is used for fixing the syringe empennage) is constant, and water content detection is frequent in the fueling operation, and the endoporus of chemical water finder is the cone-shaped body of skiving syringe front end (being the connecting portion of chemical water finder and syringe) very easily.After using more number of times, the cone-shaped body of syringe front end can be poked chemical water finder test paper, and the phenomenon of chemical water finder housing cracking can take place when using new syringe.Moreover the O-ring seal of installing on the syringe piston is aging, wearing and tearing back syringe just can not extract oil sample.Because syringe is that imported product does not have the O-ring seal fittings supply, syringe can only be scrapped.
The utility model content
Technical problem to be solved in the utility model provides a kind of vacuum type chemistry and surveys the water device, and it can improve precision of test result.
For solving the problems of the technologies described above, the technical solution that the utility model vacuum type chemistry is surveyed the water device is:
Comprise closed circuit sampler, the inner chamber of closed circuit sampler is set with syringe, and the tail end of syringe is connected with an end of connecting duct, and the head of syringe is provided with chemical water finder; The other end of connecting duct connects vacuum, and vacuum is provided with the stretching bar.The inner chamber of described syringe is provided with liquid indication ball.
Described syringe vertically is provided with in closed circuit sampler.
Described closed circuit sampler is provided with end cap, and described syringe is fixedly set in the below of end cap.
The inlet of described closed circuit sampler is provided with fillup valve, and the inlet of closed circuit sampler connects filtrator by pipeline.The outlet of described closed circuit sampler is provided with bleed valve, and the outlet of closed circuit sampler is by pipeline auxiliary connection fuel tank.
The technique effect that the utility model can reach is:
The utility model is when carrying out moisture measurement, its chemical water finder is to carry out work in the environment of closed circuit sampler sealing, test process is not subjected to the influence of extraneous moisture, and the jet fuel of being tested can access sufficient stirring, and precision of test result is high.
The utility model is easy to operate, reliable; Easy care, maintenance; Cheap, every cover price is dozens of yuan only; Syringe once drops into and need not to change, and can reduce cost greatly.
