Abstract

The invention discloses an open flashing point automatic detection device for petroleum and petroleum products, mainly comprising an automatic detecting arm, a sequence feeding disc, sample detecting cups, a heating device, a power-driven device and a control and detection circuit, wherein the automatic detecting arm is provided with a lifting screw at the tail end, with a temperature sensor, a flashing point detecting anode and cathode at the head end, and with a gas ignition arm, a high voltage ignition anode and an ignition detecting sensor; there are 6-10 sample detecting cups circumferentially and uniformly arranged on the feeding disc; the heating device is arranged below the feeding disc and provided with a lifting mechanism. 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 [0001] The invention relates to an automatic sequential sampling detection device, which is used for automatically detecting the open flash point of petroleum and petroleum products. Background technique [0002] The national standard GB / T261-83 strictly stipulates the open flash point detection method of petroleum and petroleum products. Under these strictly regulated conditions, the traditional measurement method is to use combustible gas for artificial ignition, scanning, manual temperature adjustment, and manually observe the flash point temperature value of the sample indicated by the mercury column of the thermometer at the moment when the sample flash point occurs. The manual detection device and method are cumbersome to operate, have large measurement errors, and are inconvenient to use. Summary of the invention [0003] The purpose of the present invention is to provide an automatic detection device for the open flash point of petroleum and petroleum prod...
