Description
Technical field
The present invention relates to motor fuel flash-point burning-point index test technical field, be specially a kind of automatic open flash-point determination of ignition point instrument.
Background technology
Petroleum products is heated to the minimum temperature its steam contacts flame generation scintillation during with the combination gas of air under the rated condition of this method, is called opening agar diffusion method flash-point.The flame that the steam that petroleum products is heated to it under the rated condition of this method can be touched is lighted and the minimum temperature of burning when being no less than 5s, is called opening agar diffusion method burning-point.This method is applicable to the opening agar diffusion method flash-point and the open cup burning-point that measure lubricating oil and deep color petroleum product.
When fluid temperature is lower, because evaporating temperature is low, velocity of evaporation is slow, and the vapour molecule concentration that ullage is formed is smaller, and may be less than lower explosive limit, the mixed gas that now vapour molecule and air are formed runs into burning things which may cause a fire disaster and can not be lighted.Along with the continuous rising of temperature, vapour molecule concentration increases, when vapour molecule concentration increases to lower explosive limit time, the mixed gas that the saturated vapor of flammable liquid and air are formed runs into burning things which may cause a fire disaster can there is the phenomenon that namely a sudden strain of a muscle extinguish, and this one dodges the phenomenon that deflagrates of namely going out is called flash burn.
At the specified experimental conditions, corresponding during liquid surface generation flash burn minimum temperature is called the flash-point of this liquid.Under flash temperature, can only there is flash burn and can not occur sustained combustion in liquid.This is because under flash temperature, the velocity of evaporation of flammable liquid is less than its burning rate, and the steam of ullage burns up rear steam and has little time to supplement, and causes flame self-extinguish.Continue raised temperature, ullage vapor concentration increase, when the potpourri that vapour molecule and air are formed run into burning things which may cause a fire disaster can burn and the duration is no less than 5 seconds time, now liquid is lighted, and the temperature corresponding to it is called the burning-point of this liquid.From fire-fighting viewpoint, flash burn is the warning of fire, the prelude caught fire.Grasp this combustion phenomena of flash burn, just can fire preventing occur or reduce the harm that causes of fire well.

Principle of work of the present invention is:
Flash-point pattern
Test the flash-point of oil sample and record its flash temperature; When starting to heat, when oil sample temperature arrives expection first 56 DEG C of flash-point, the programming rate of oil sample is 14 ~ 17 DEG C per minute, when oil sample temperature arrives expection flash-point 28 DEG C, be 5 ~ 6 DEG C per minute, when expecting first 28 DEG C of flash-point, draw and sweep bar and start to sweep and draw, temperature often raises 2 DEG C, draws and sweeps once; Systems axiol-ogy is to flash-point, and now system is by display measurement result, and hummer rings a sound, and cooling system opens cooling automatically, and carry arm will lift after pressing " F5 " key, and turns back to standby condition interface.
System will stop heating after higher than design temperature 20 DEG C, and cooling system is opened, and liquid crystal display " presets flash temperature value too low if flash-point do not detected! ", hummer rings a sound.Carry arm will lift after pressing " F5 " key, and turns back to standby condition interface.
Burning-point pattern
Test the burning-point of oil sample and record its ignition temperature, but the flash-point not record occurred; When starting to heat, when oil sample temperature arrives expection first 56 DEG C of flash-point, the programming rate of oil sample is 14 ~ 17 DEG C per minute, when oil sample temperature arrives expection flash-point 28 DEG C, be 5 ~ 6 DEG C per minute, when expecting first 28 DEG C of flash-point, draw and sweep bar and start to sweep and draw, temperature often raises 2 DEG C, draws and sweeps once; Oil sample sustained combustion at least 5 seconds, system will detect burning-point, and now system is by display measurement result, and hummer rings a sound, and cooling system opens cooling automatically, and carry arm will lift after pressing " F5 " key, and turns back to standby condition interface.
System will stop heating after higher than default flash temperature 50 DEG C, and cooling system is opened, and liquid crystal display " presets flash temperature value too low if burning-point do not detected! ", hummer rings a sound.Carry arm will lift after pressing " F5 " key, and turns back to standby condition interface.
Flash-point burning-point pattern
The flash-point of test oil sample and burning-point, and flash-point, ignition temperature that record first time occurs; When starting to heat, when oil sample temperature arrives expection first 56 DEG C of flash-point, the programming rate of oil sample is 14 ~ 17 DEG C per minute, when oil sample temperature arrives expection flash-point 28 DEG C, be 5 ~ 6 DEG C per minute, at expection first 28 DEG C of flash-point, draw and sweep bar and start to sweep and draw, temperature often raises 2 DEG C, draws and sweeps once.After first time flash-point being detected, hummer rings a sound, and on liquid crystal, show flash temperature value; System continues with the speed of 5 ~ 6 DEG C per minute heating, often to raise 2 DEG C strokes and sweep once, test burning-point; When oil sample sustained combustion more than 5 seconds, system will detect burning-point, now system is by display measurement result, hummer rings a sound, and cooling system opens cooling automatically, and jacking system lifts automatically, fire extinguishing lid stretches out fire extinguishing, fire extinguishing is covered after pressing " F5 " key will indentation, and turns back to standby condition interface, and cooling system will cut out after 20 minutes.
System will stop heating after higher than default flash temperature 50 DEG C, and cooling system is opened, and liquid crystal display " presets flash temperature value too low if flash-point burning-point do not detected! ", hummer rings a sound.Carry arm system will be lifted after pressing " F5 " key, and turns back to standby condition interface.
