6、電子點火,強制風冷(注 手動點火按鍵位于儀器箱體左側)。

四、全自動開口閃點儀工作原理
本儀器在中華人民共和國標準GB/T 3536規定的條件下,把試樣裝入試驗杯,對裝有試驗油的試驗杯加熱,產生的石油蒸氣與周圍空氣形成的混合氣體在火焰接觸發生閃火時的zui低溫度,作為該試樣的閃點。
繼續試驗,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及外圍電路組成信號采集、處理、計算、輸出、控制等系統。工作時,根據傳感器所采集的溫度變化情況由CPU發出指令,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、微分檢測等均實現自動控制。
當閃點被測出時,計算機系統停止數據采集,顯示閃點溫度并打印記錄結果;若需繼續測試燃點,則儀器繼續加熱,當燃點被測出并燃燒5秒后,蓋板自動關閉火焰,大臂自動抬起,實驗結束。

I. Summary
The instrument is designed and made as per the National Standard of People’s Republic of ASTM/ D92,China GB/T3536 “Test Methods for Flash Point and Fire Point of Petroleum Products (Cleveland Open Cup Methods)”. It is suitable to determine the Cleveland open cup flash point of petroleum products, excepting fuel oils and petroleum products having open cup flash point lower than 79 ℃.
The instrument adopts SCM controlling technologies, colored LCD screen, man machine conversation interface, and blank buttons. The expected flash point, sample serial number, barometric pressure and test date can be preset. It has menu prompt and input guide function. It uses open, fuzzy control software, and modularization structure. It is advanced, friendly, convenient, and accurate, so it is the best choice of similar instruments. It has been widely used for petroleum products flash point and fire point test in the field of railway, aviation, power, petroleum, scientific research institutes, measurement and inspection department, and college and universities.
 
II. Main technical specification and parameters
1. Power supply: AC 220V±10%, 50 Hz;
2. Temperature measurement:
(1) Measurement range: room temperature400℃;
(2) Repeatability: ≤4℃;
(3) Reproducibility: ≤8℃;
(4) Resolution: 0.1℃;
(5) Accuracy: 0.5%;
3. Temperature rising speed: as per GB/T3536;

III. Instrument characteristics
1. The instrument adopts colored LCD screen, man machine conversation interface, and blank buttons. It can preset parameters, such as temperature, sample serial number, barometric pressure, and test date, etc. It has prompt menu and input guide functions.
2. It can show temperature-time curve. It has prompt function for operation error, and prompt function for test date and test time.
3. It can correct the effect of barometric pressure to the test and calculate the modified value.
4. It is with differential detection function. It can correct the system deviation automatically.
5. Flame application, flash point detection, and test data printing can be completed automatically. The test arm can be raised up and lowered down automatically.
6. It is with electron igniter and it has forcible wind cooling function (Note: The manual flame application button is at the left side of the instrument).

 

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.
