Strictly speaking, lubricants that exceed the shelf life are not recommended. However, if there is a large amount of oil and it is discarded and worried about waste, then the oil quality problem can be investigated from the following aspects.
Strictly speaking, lubricants that exceed the shelf life are not recommended. However, if there is a large amount of oil and it is discarded and worried about waste, then the oil quality problem can be investigated from the following aspects.
The first is to conduct a preliminary inspection. Under normal circumstances, the lubricant should be a clear, translucent or transparent liquid. If the lubricant oxidizes, the color changes. In addition, the transparency of the lubricating oil is lowered, indicating that the oil quality of the lubricating oil has changed. If the smell of the lubricating oil is sour and stinky, it means that it has deteriorated. In addition, if the viscosity of the oil can be observed to change significantly (thinning, thickening), the properties are not uniform, it is not suitable to use.
1 type of lubricating oil
After long-term storage, lubricating oils with more complex additives are more prone to problems. For example, automobile engine lubricating oil (oil oil), if the additive is used more, the possibility of changing and separating the additive property is relatively large after long-term storage. If the additive composition of the lubricating oil is relatively simple, such as an anti-oxidation and anti-rust lubricating oil, the risk of separation of the additive after long-term storage is relatively small.
2 lubricating oil storage conditions
The main reasons for the deterioration of lubricating oil are: whether it is sealed and stored, whether it is cool and dry, air oxidation, high temperature, oil contamination (anything other than lubricating oil is impurities, including dust, moisture, etc.) and sun exposure. If these conditions occur during the storage of the lubricating oil, the deterioration rate of the oil quality will be significantly accelerated.
3 How long does the lubricant last longer than the shelf life?
How long is the storage time of the lubricating oil? If the shelf life is more than one or two months, the difference between the one and two years of the warranty period will definitely be large. Secondly, where is the lubricant used? Is the machine that uses the oil important? If it fails, will it cause a big loss?
In general, the storage time of industrial lubricants is recommended to be within 1 year and the grease is less than half a year. In order to ensure good equipment lubrication, the lubricant should be stored in the first-in-first-out manner to avoid long-term storage of the lubricating oil. The above method is only to qualitatively evaluate the oil quality of the lubricating oil after storage. If the lubricating oil has a large amount of oil and does not want to be wasted, it is best to do a fluid test (oil analysis) before using the lubricating oil that exceeds the shelf life. Oil testing Through professional testing equipment, it can quantitatively and accurately determine the oil quality of lubricating oil.

Pressure sensor usually consists of a pressure sensor and a signal processing unit for measuring the pressure of liquids and gases. According to different test pressure types, pressure sensors can be divided into gauge pressure sensors, differential pressure sensors and absolute pressure sensors. According to the working principle, it can be divided into Ceramic Pressure Sensor, diffusion silicon pressure sensor, piezoresistive pressure sensor, sapphire pressure sensor and so on.
