Introduction: With the continuous advancement of science and technology, the requirements for the reliability and safety of machinery and equipment are also increasing. The monitoring of working conditions based on the operating state of machinery and equipment is also receiving more and more attention from all countries, and the pollution of oil is the result of hydraulic pressure. The main cause of failure in the lubrication system. Oil analysis and testing is equivalent to human blood testing, its importance is self-evident, oil pollution is the main cause of equipment failure and service life, and water pollution in oil is one of the most common pollution, oil Water contamination in the liquid can cause many problems such as additive loss, lubricating oil oxidation, corrosion, reduction in lubricant film thickness, and microbial growth. Therefore, it is necessary to use the oil moisture detector to perform irregular inspection of the oil and to grasp the pollution information, thereby preventing and reducing the downtime of the equipment. Yatai Photoelectric Oil Moisture Analyzer uses a constant temperature heater to heat it, and controls the heating temperature between the boiling point of oil and water to vaporize the water in the oil. Its volume expands more than 1000 times and the moisture content is greater than 0.1%. A popping sound can be formed. The air bubble in the oil does not expand more than twice its volume after heating, and does not produce a popping sound. Therefore, whether the lubricating oil or the hydraulic oil can continue to be used can be judged according to the presence or absence of the popping sound, and the amount of water in the oil can be judged according to the number and size of the bubbles. Steps: 1. Wipe the two oil pools on the copper rod with cotton cloth, toilet paper or other absorbent material. 2. Plug in the AC 220V power supply, turn on the power switch, and the power indicator light is on. After 3 to 5 minutes, drop a drop of water in the oil pool of the copper rod. If the sound is "sou sou", and the water droplets vaporize and evaporate, explain After the heat is over, you can test it. If there are no bubbles in the water droplets, the instrument is faulty. 3. Method 1: Shake the test oil sample, insert it into the oil sample with the sampling rod and lift it again, and drop a drop (about 24 mg) of the oil sample into any oil pool. If it bursts, it indicates that it is in the oil sample. The water content exceeds the standard requirements, and the cause of the water ingress must be checked immediately and the oil replaced. If only one drop of oil is dropped into the oil sample, there is no sound, and three drops are continuously dripped in order to get a popping sound. The number of bubbles is more than 10 and the diameter is larger than 1 mm, indicating that the moisture content in the oil sample is between 0.1% and 0.2%. For hydraulic oils, moisture has exceeded the standard requirements and needs to be replaced; for lubricants, close monitoring is required. Whether it is dripping a drop or a lot of oil in the oil pool, there are only 10 small (within 0.8mm diameter) bubbles, which means that the water in the oil is within the standard requirement and the content is less than 0.1%. 4. Method 2: Determine the water content by comparing with the standard water-containing oil sample. Prepare the standard oil sample containing 0.1% and 0.2% water with the new oil to be tested, and drop one drop of the standard oil sample into one oil pool, while in another Drop a drop of oil sample to be tested in an oil pool, and carefully observe the size and quantity of the bubbles in the two oil pools. If the number of bubbles formed by the oil sample to be tested is small and the diameter is small, it is treated as compared with the standard oil sample. The water content of the oil sample is smaller than the standard oil sample, and vice versa. 5. After use, turn off the power, pull the plug, and after it is completely cooled, wipe the heater with a soft paper or cloth.
