The device is used for automatic detection of the petroleum and petroleum products open flashing point, has simple operation, high degree of automation, accurate and reliable measurement, and has obvious improvement compared to the existing artificial detection device.
Description
Technical field
The present invention relates to a kind of automatic sequence sample detection device, be used for detecting automatically the open flash point of oil and petroleum products.
Background technology
GB GB/T261-83 strict regulations the detection method of open flash point of oil and petroleum products.Under the condition of these strict regulations, traditional assay method utilizes combustible gas to carry out the manual firing exactly, scanning, and artificial temperature adjustment, the moment of manual observation sample generation flash-point is by the sample flash temperature value of the mercury slug indication of thermometer.The apparatus and method complex operation of this manual detection, measuring error is big, uses inconvenient.
Summary of the invention
The object of the present invention is to provide a kind of easy and simple to handle, automaticity is high, measure oil and petroleum products open flash point automatic detection device accurately and reliably.
Technical scheme of the present invention is: oil and petroleum products open flash point automatic detection device; Mainly constitute by automatic detection arm, sequence sample introduction dish, sample detection cup, heating arrangement, Power Drive Unit and control and testing circuit; Said automatic detection arm tail end is provided with the lifting screw perpendicular to sequence sample introduction dish; Head is provided with gas ignition arm, the high-tension ignition utmost point, temperature sensor, flash-point detection anode and negative electrode, and it is 6～10 that said sample detects cup, evenly is arranged on the sequence sample introduction dish by circumferencial direction; Said heating arrangement is positioned at sequence sample introduction dish below, and has elevating mechanism.
Further scheme is: said Power Drive Unit is motor one cogwheel gearing; Said flash-point detects anode for being mutually 120
0Three of Y shape detect pins, process by platinum wire or chromium steel silk, it is the aluminium ring that flash-point detects negative electrode; Distance is 7mm between said detection pin needle point and the aluminium ring, and current potential is 10KV; The igniting position is provided with the igniting detecting sensor in this device.
The course of work of this device is: sample (liquid or thick liquid) is respectively charged into individual (n=6～10) sample of n detects a groove line (quantitatively volume) of extremely stipulating in the cup, put into sample by numbering and detect cup.Start instrument, let instrument be in original state to be detected.Next, on the panel of control device, configure the flash temperature value (be also referred to as preflashing point temperature value, this value is than low 10 ℃ of actual flash-point value usually) that each sample is pre-estimated.The actuating unit working routine is positioned at the beneath well heater of sample detection cup sample is heated automatically.The rate of heat addition of this moment is higher, generally is set at 6～10 ℃ (programmed control).Specimen temperature is by the specimen temperature sensor.When specimen temperature reaches preflashing point temperature value; The gas control valve of gas ignition arm is opened; High-tension ignition limit fire; The end of gas ignition arm produces the high flare of 2mm immediately, and the motor that drives the gas ignition arm makes the gas ignition arm detect between the cup and the high-tension ignition utmost point at sample and does periodic horizontal backswing campaign.In this process, make the rate of heat addition slow down, generally be set at 1～2 ℃ (programmed control).When the medium between flash-point detection anode and negative electrode is air or oil and Air mixing gas; Flash-point detects between anode and the negative electrode and does not produce pulse; In case sample produces scintillation, promptly specimen temperature reaches flash temperature, and the medium that flash-point detects between anode and the negative electrode just becomes flame; Flash-point detects between anode and the negative electrode and produces pulse, and device can detect the signaling point that the sample flash-point takes place immediately.Device control circuit reads the specimen temperature value that the specimen temperature sensor is experienced rapidly, stores the concurrent order of losing one's life of this value, closes gas control valve.
And then, instrument under the order of programmed instruction, the elevating mechanism of the automatic detection arm that rises simultaneously and decline sample heating arrangement, its position is by the control of photoelectricity or contact switch.After this command execution, next instrument carries out the rotating mechanism of interval stage by stage of sample introduction dish, treats that the sample introduction dish turns over 360
0After the angle of/n, programmed instruction command device descend simultaneously automatic detection arm and rising sample heating arrangement, next, instrument repeats the testing of second sample.Directly all accomplish from n sample analysis, computer writes down the flash-point value of n sample automatically, and the request printing lets the user freely select.Instrument lets instrument get into the detected state of next cycle automatic rise detection arm and decline sample heating arrangement.
Scintillation when taking place in sample; Certain top position that generally is positioned at sample detection cup groove occurs at random; Pattern is that half sample detects about the cup round mouth, and existing open flash point detection device generally only has place flash-point detection position point, easily omission sample flash-point origination point.This pick-up unit guarantees that along sample three the flash-point detection position points that detected cup round mouth place uniform Design sample captures the flash of light origination point accurately in the moment that scintillation takes place.
The gas ignition arm through the constraint of fine motion contact switch, is done horizontal backswing campaign under the driving of drive motor.The end of gas ignition arm produces the high flare of 2mm.Sometimes, under unexpected situation, the flare that 2mm is high can extinguish.When the backswing of the end of gas ignition arm to igniting during detecting sensor, the igniting detecting sensor will detect flare to be extinguished, and restarts the high-tension ignition utmost point and produces flare.Directly after sample produces scintillation, close the igniting source of the gas, stop scanning.
Flash-point detects anode and detects being directly proportional with the current potential Vi that flash-point detects between the negative electrode with flash-point detection anode apart from a between the negative electrode with flash-point.Vi is about 10KV in this device, about a=7mm, detects effective.
