Abstract
Disclosed is a diesel closed cup method flash point tester which can judge if a diesel closed cup method flash point value meets the standard requirement in China. The heating power of the utility model is less than 400 W. The heat radiated by the heating element is used to directly heat an integrated oil cup filled with the tested diesel to make the temperature of the diesel increase steadily and evenly; after the temperature reaches 55 DEG C, one ignition test is taken when the temperature is increased by one DEG C each time and if two successive flash fire conditions occur, the diesel closed cup flash point value can be judged not to meet the standard requirement in China.
Description
The utility model relates to a kind of remain silent testing tool of agar diffusion method flash-point value of petroleum products of measuring, and especially can make things convenient for, judge accurately, at low cost the diesel oil of remaining silent diesel oil whether agar diffusion method flash-point value the complying with the national standard requirements agar diffusion method flash-point value determinant of remaining silent.
At present, the known petroleum products agar diffusion method flash-point value tester device of remaining silent is made up of heating arrangement, stirring apparatus, oil-cup device, temperature measuring equipment, portfire.Petroleum products is added in the airtight lubricating cup, under continuous stirring condition, heat the temperature of tested petroleum products gradually, stop after every rising uniform temperature stirring, utilize portfire to carry out fire trial, till the liquid level of tested petroleum products recurred twice scintillation, temperature measuring equipment temperature displayed value was exactly the agar diffusion method flash-point value of remaining silent of this petroleum products when for the first time scintillation taking place.Usually petroleum products remain silent agar diffusion method flash-point value solid kind about 200 ℃, light weight fluid class such as diesel oil about 70 ℃, poor ignition quality fuel is about 20 ℃.The qualified diesel oil of the regulation agar diffusion method flash-point value of remaining silent should be not less than 55 ℃ in the national standard (GB255), and the agar diffusion method flash-point value of remaining silent is defective if tested diesel oil, is then declared this diesel oil at double generation scintillation below 55 ℃.Under many circumstances, people only want whether the agar diffusion method flash-point value of remaining silent of judging tested diesel oil complies with the national standard requirements, promptly whether be not less than 55 ℃, specifically what are and be indifferent to the flash-point value, the known agar diffusion method flash-point value tester device of remaining silent is to measure the petroleum-type product all purpose instrument of agar diffusion method flash-point value of remaining silent, so it is big to regulate temperature range, about room temperature to 300 ℃, cause the power big (being not less than 400W) of its heating arrangement, the power consumption height; Heat insulation, insulated part is complicated; For guaranteeing tested petroleum products thermally equivalent, oil-cup device is made up of complex component such as air bath cover, lubricating cups, by the tested petroleum products of air indirect heating; It is low etc. to regulate the precision of temperature in room temperature to 60 ℃ scope, be not suitable for amateur reviewer and judge whether the diesel oil agar diffusion method flash-point value of remaining silent meets request of national standard, only judge diesel oil remain silent agar diffusion method flash-point value inconvenience when whether meeting national standard, inaccurate, cost is high.
The purpose of this utility model provides a kind of diesel oil agar diffusion method flash-point value determinant of remaining silent, and it not only can measure the diesel oil agar diffusion method flash-point of remaining silent, and can make things convenient for, judge accurately, at low cost whether the diesel oil agar diffusion method flash-point value of remaining silent complies with the national standard requirements.
The purpose of this utility model is achieved in that the power that reduces heating arrangement, make its maximum heating power less than 400W, the air bath cover and the lubricating cup of oil-cup device are made of one the formula lubricating cup, and the heat that heating arrangement gives out directly heats the integral type lubricating cup that tested diesel oil is housed.Because of heating power little, the temperature of tested diesel oil is heated to 55 ℃ by room temperature, just can regulate firing rate easily, realize temperature steadily, at the uniform velocity rise, carry out fire trial every certain temperature being heated to before 55 ℃, if double generation scintillation then show that this diesel oil agar diffusion method flash-point value of remaining silent does not meet the national standard requirement is promptly defective; If be heated to 55 ℃ when carrying out fire trial, scintillation does not take place then to be shown and comply with the national standard requirements, promptly qualified, thus be able to judge the purpose of remaining silent diesel oil whether agar diffusion method flash-point value index complying with the national standard requirements.
Owing to adopt such scheme, can when remaining silent agar diffusion method flash-point value, measurement diesel oil judge easily and accurately whether it complies with the national standard requirements, saves energy again, heat insulation, part-structures such as insulation, oil-cup device are simple, make, and use cost is low, degree of regulation height in the temperature range is convenient to amateur reviewer and is used.
Below in conjunction with drawings and Examples the utility model is further specified.
Accompanying drawing is the partial sectional view of the utility model embodiment, and 1. driving snakes, 2. igniter head supports, 3. igniter head, 4. fire holes among the figure (oil hole of holding concurrently) are thermometer 6. slide plates 7. oil cup caps 8. heating elements 9. integral type lubricating cups 10. oil drain holes 11. oil drain hole valves 12. paddles 13. housings 14. heat insulation sheaths 15. switch boxes 5.
In the embodiment shown in the figures, external force drives paddle (12) by driving snake (1) and rotates, igniter head (3) is placed on igniter head support (2), thermometer (5) extend into integral type lubricating cup (9) inside by slide plate (6) and oil cup cap (7), by heat insulation sheath (14) integral type lubricating cup (9) is connected indirectly with housing (13).Tested diesel oil is injected into the integral type lubricating cup (9) from fire hole (4), by-pass cock case (15), the heating power of control heating element (8), tested diesel oil in while paddle (12) the continuous stirring integrated formula lubricating cups (9), make diesel fuel temperature steady, at the uniform velocity rise, the indicated temperature of thermometer (5) less than 55 ℃ before, after every rising uniform temperature, stop to stir, moving slide board (6) makes igniter head (3) carry out fire trial by fire hole (4), if double generation scintillation, show that then the tested diesel oil agar diffusion method flash-point value of remaining silent does not meet the national standard requirement, the diesel oil of checking is emitted by oil drain hole (10) and oil drain hole (11).
Claims (2)
1, a kind of diesel oil agar diffusion method flash-point value determinant of remaining silent is made up of housing, heating arrangement, stirring apparatus, oil-cup device, temperature measuring equipment, portfire, and it is characterized in that: the heating power of heating arrangement is less than 400W.
2, the diesel oil according to claim 1 agar diffusion method flash-point value determinant of remaining silent is characterized in that: the heat that heating arrangement gives out directly heating is equipped with the integral type lubricating cup of tested diesel oil.
