Abstract
The utility model discloses a petroleum and petroleum product opening flash point detector, which mainly consists of a high-voltage ignitor, a gas ignition arm, a test sample detection cup, a flash point detection anode, a flash point detection cathode, a test sample temperature sensor and a control circuit. The ignitor and the gas ignition arm are arranged at the upper part of a front panel; the cup opening of the detection cup is arranged above the front panel; the detection anode and the detection cathode are respectively positioned at the center and the periphery of the detection cup opening; the temperature sensor extends into the detection cup; three evenly distributed detection heads are arranged on the detection anode; an ignition detection sensor is arranged near the ignitor. The detector is used for detecting the opening flash point of the petroleum and petroleum product; can realize automated detection through an electronic circuit and process control, has simple operation, reliable detection, high detection precision, and fully accords with international standard requirement.
Description
Technical field
The utility model relates to the temperature measuring equipment that is used for 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.
The utility model content
The purpose of this utility model 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.
The technical solution of the utility model is: this oil and petroleum products open flash point detection device are mainly by the high-tension ignition utmost point, the gas ignition arm, sample detects cup, flash-point detects anode, flash-point detects negative electrode, the specimen temperature sensor, panel and control circuit constitute, the described high-tension ignition utmost point, the gas ignition arm is 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 cup rim of a cup and on every side, the specimen temperature sensor extend into sample and detects in the cup, flash-point detects anode and is provided with equally distributed three detection heads, and distance is 6～8mm between detection head and the flash-point detection negative electrode.
Further scheme is: be provided with the igniting detecting sensor near the described high-tension ignition extremely; The detection head that described flash-point detects on the anode is platinum wire or chromium steel silk, and it is the aluminium ring that described flash-point detects negative electrode, and there is the blackout oxide layer on the surface; Described gas ignition arm be located at panel under be connected by the motor of microswitch control; The left and right extreme position of described gas ignition arm horizontal hunting is mutually close with the high-tension ignition utmost point and test portion detection cup rim of a cup respectively; Described sample detects cup cup end having heaters.
The course of work of this device is: sample (liquid or the thick liquid) sample of packing into is detected in the cup a 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 pre-flash-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 pre-flash-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, 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, be that 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 by electronic circuit, programmed control robotization detects, and is easy and simple to handle, the accuracy of detection height; Flash-point detects anode and is provided with three uniform check points, 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; As 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.
