四、全自動開口閃點測試儀工作原理
本儀器在中華人民共和國標(biāo)準(zhǔn)GB/T 3536規(guī)定的條件下，把試樣裝入試驗杯，對裝有試驗油的試驗杯加熱，產(chǎn)生的石油蒸氣與周圍空氣形成的混合氣體在火焰接觸發(fā)生閃火時的zui低溫度，作為該試樣的閃點。
繼續(xù)試驗，直到用試驗火焰使試樣點燃并至少燃燒5秒鐘的zui低溫度，作為該試樣的燃點。
本儀器由單片計算機(jī)及外圍電路組成信號采集、處理、計算、輸出、控制等系統(tǒng)。工作時，根據(jù)傳感器所采集的溫度變化情況由CPU發(fā)出指令，控制加熱器，使試樣溫度按一定速率上升；掃描周期、點火時間、微分檢測等均實現(xiàn)自動控制。
當(dāng)閃點被測出時，計算機(jī)系統(tǒng)停止數(shù)據(jù)采集，顯示閃點溫度并打印記錄結(jié)果；若需繼續(xù)測試燃點，則儀器繼續(xù)加熱，當(dāng)燃點被測出并燃燒5秒后，蓋板自動關(guān)閉火焰，大臂自動抬起，實驗結(jié)束。

IV. Working principle
Fill sample in the oil cup, and then heat the oil cup at the condition stipulated in the National Standard of People’s Republic of China GB/T3536. The flash point is expressed as the lowest temperature, when the gas mixture of oil sample vapor and the air around contacts flame and appears flash.
Continue to test, and take the lowest temperature when the sample is on fire and burns for at least 5 s as the fire point of the oil sample.
The instrument adopts SCM and outer circuit to form signal collection, processing, calculation, output, and control system. The CPU will send an order to control the heater as per the temperature change collected by the sensor so that the sample temperature can rise at a constant rate. The flame application, flame application interval, and flash detection can be automatically controlled.
When the flash point is detected, the instrument will stop collecting data. Then it will show flash point temperature and print out test data. If you need to determine the fire point, please continue heating the sample. When there is fire appears and the sample is burning for 5 s, the fire will be extinguished by the fire extinguishing plate. Then the arm will be raised up and the test is over.
