The device is used for detecting the open flash point of the petroleum and the petroleum products, realizes automatic detection through an electronic circuit and a program control, operation is convenient, detection is reliable, detection precision is high, which satisfies requirement of international rules.
Description
Technical field
The present invention relates to be used for the temperature measuring equipment of petroleum industry, particularly a kind of oil and petroleum products open flash point detection device.
Background technology
GB GB/T261-83 strict regulations the detection method of open flash point of oil and petroleum products.Traditional assay method is to utilize combustible gas to carry out the manual firing, scanning, artificial temperature adjustment; The sample flash temperature value of thermometer indication between an instant of manual observation sample generation flash-point, complex operation, measuring error is big; Use inconvenience, be difficult to reach the requirement of GB regulation.
Summary of the invention
The purpose of this invention is to provide a kind of easy and simple to handle, accuracy of detection is high, the oil of good reliability and petroleum products open flash point detection device.
Technical scheme of the present invention is: this oil and petroleum products open flash point detection device mainly detect cup, flash-point detection anode, flash-point detection negative electrode, specimen temperature sensor, panel and control circuit by the high-tension ignition utmost point, gas ignition arm, sample and constitute; The said high-tension ignition utmost point, gas ignition arm are arranged on the panel top; The rim of a cup that sample detects cup is placed on the panel; Flash-point detects anode and flash-point and detects negative electrode and lay respectively at sample and detect the center of glass rim of a cup and on every side; The specimen temperature sensor extend into sample and detects in the cup; Improvements are that flash-point detection anode is provided with equally distributed three detection heads, and distance is 6～8mm between detection head and the flash-point detection negative electrode.The detection head that said flash-point detects on the anode is platinum wire or chromium steel silk, and it is the aluminium ring that said flash-point detects negative electrode, and there is the blackout oxide layer on the surface; Said gas ignition arm be located at panel under be connected by the motor of microswitch control; The left and right extreme position of said gas ignition arm horizontal hunting respectively with the high-tension ignition utmost point and test portion detect the cup rim of a cup near; Said sample detects cup cup end having heaters.
Further scheme is: be provided with the igniting detecting sensor near the said high-tension ignition extremely.
The course of work of this device is: sample (liquid or the thick liquid) sample of packing into is detected in the cup groove line (quantitatively volume) to regulation; On the panel of control device, configure the flash temperature value of pre-estimating (be also referred to as preflashing point temperature value, this value is than low 10 ℃ of actual flash-point value usually).The starter gear 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 ℃ of per minutes (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 gas ignition arm is controlled by motor-driven and microswitch, detects between the cup and the high-tension ignition utmost point at sample and does the left and right swing of periodic level.In this process, make the rate of heat addition slow down, generally be set at 1～2 ℃ of per minute (programmed control).When the medium between flash-point detection anode and the negative electrode was air or oil and Air mixing gas, flash-point detected between anode and the negative electrode and does not produce pulse.In case sample produces scintillation, promptly specimen temperature reaches flash temperature, an oil gas sample that detects the cup top arm point sudden strain of a muscle of being lighted a fire; The medium that flash-point detects between anode and the negative electrode just becomes flame, and flash-point detects between anode and the negative electrode and produces pulse, and this moment, device control circuit read the specimen temperature value that the specimen temperature sensor is experienced rapidly; Store the concurrent order of losing one's life of this value; Close gas control valve, stop motor rotation, export by printer prints again.
This device realizes that through electronic circuit, programmed control robotization detects, and easy and simple to handle, accuracy of detection is high; Flash-point detects anode and is provided with three check points that are uniformly distributed with, and guarantees to detect like clockwork the flash-point of sample, detects anode and negative electrode and adopts ad hoc structure and material, has improved usability; Like fortuitous event, when the igniting flare of gas ignition arm extinguished, the igniting detecting sensor can restart high-tension ignition limit combustion flare, and the assurance testing is carried out smoothly, has improved detecting reliability.
