Recently, it was developed by the Air Force Metrology Station to calibrate and verify a certain type of imported "Warrior Blood Tester" - the standard substance of the oil contaminant detector successfully passed the identification, and rewritten the calibration and verification of this type of instrument for a long time. The history of the material has filled the gap in the country and became the first oil testing standard material approved by the state.
After the post-doctoral Zhu Zixin received the task, everything started from scratch. In order to consult the collected materials, ask the relevant questions, they have only two research institutes in the country to dozens of standard research units; in order to optimize the formulation of standard substance ingredients, they have tried more than 1200 times with nearly 20 kinds of chemical raw materials and medicines; To determine the value of the standard substance, each month, they have to manually count more than 12,000 particles under the microscope. This experiment has done at least 13 times...

The gear level and oil condition should be checked at least every six months and it is recommended to change every 40,000 km. According to incomplete statistics, about 70% of transmission failures are related to oil damage and oxidation. The level of the oil level has a great influence on the operation of the gearbox. When the liquid level is too low, the air may enter the internal circulation of the oil pump and mix with the oil to cause the oil to decompose, and the gas resistance generates an abnormal sound, and the oil The pressure is difficult to establish or the oil pressure is too low, causing the clutch and brake to slip and burning the gearbox.
The Oil Contamination Monitor meets the shortcomings of the laboratory's non-movable test of the desktop. Whether you are online or laboratory, you will be provided with a complete test plan to make your test more convenient. The ultra-precision flow electromagnetic control system is adopted to realize the double control with constant injection speed and accurate injection volume. The sampling amount is 1ml~60ml, which is set accurately and accurately. The sensor uses Proud's classic "resistance measuring particle" sensor, which is more suitable for NAS1638 and ISO4406. Built-in threshold, particle size curve and pulse resistance can be set to arbitrarily set the channel particle size value. Built-in operating system and micro-printer, no need to connect to a computer and printer for direct testing and printing. With standard serial RS232 port, it can be connected to the computer to store test results, which is convenient for data classification and retrieval. It can be calibrated and calibrated according to GB/T18854-2002 (ISO11171-1999, JJG066-95) and other standards. Applications are more extensive, in the fields of aviation, aerospace, military, military, hydraulic, marine, electric power, petroleum, chemical, transportation, port, metallurgy, machinery, automobile, manufacturing, etc., for the detection of solid particle contamination of various types of oil.
The oil pollution monitor can monitor and analyze oil particle size, cleanliness, pollutants; hydraulic equipment and its routine maintenance and maintenance; wear test of hydraulic components; insoluble particles in pure solution and ultrapure water. This instrument adopts the core technology of Proud in the UK - "Photoresist Measurement Particles", and adopts the oil industry classic methods NAS1638 and ISO4406, and can be built according to the requirements of users.
Through two years of unremitting efforts, the institute obtained the national license for the manufacture of the reference material while the development results were certified by the National Standards Substance Management Committee. As of September, the hospital has completed the acceptance and calibration of 60 detectors using the standard materials. The first batch of 200 bottles will be dispatched in the near future to fully replace imported standards.
Aluminium foil (or Aluminum Foil), often referred to with the misnomer tin foil, is aluminium prepared in thinmetal leaves with a thickness less than 0.2 mm (7.9 mils); thinner gauges down to 6 micrometres (0.24 mils) are also commonly used.
Aluminium foil is produced by rolling sheet ingots cast from molten billet aluminium, then re-rolling on sheet and foil rolling mills to the desired thickness, or by continuously casting and cold rolling. To maintain a constant thickness in aluminium foil production, beta radiation is passed through the foil to a sensor on the other side. If the intensity becomes too high, then the rollers adjust, increasing the thickness. If the intensities become too low and the foil has become too thick, the rollers apply more pressure, causing the foil to be made thinner.
Aluminium is used for packaging as it is highly malleable and can be easily converted to thin sheets and can be easily folded, rolled and packed.it is also used broadly in food and pharmaceutical packaging. The purpose of aluminium is to make long-life packs (aseptic packaging) for drinks and dairy goods, which allows storing without refrigeration. Aluminium foil containers and trays are used to bake pies and to pack takeaway meals, ready snacks and long life pet foods.
