The viscosity temperature characteristics of lubricating oil reflect its performance from another perspective. The viscosity of lubricating oil first affects its lubrication performance, and the viscosity of lubricating oil varies nonlinearly with temperature. Within the operating temperature range of equipment, excessive viscosity changes are difficult to ensure smooth operation of the equipment. Therefore, lubricating oil for equipment should consider selecting oil with good viscosity and temperature characteristics to achieve ideal operating results.

In addition, monitoring of wear particles and pollutants in oil is also very important. Due to the inevitable friction between various friction pairs during the operation of mechanical equipment, when the oil deteriorates or is contaminated by impurities, the wear of the equipment intensifies, and wear particles of different shapes enter the lubricating oil. If not detected in time, it will affect the service life of the machine, and in severe cases, shutdown accidents may occur.

It can be seen that the reasonable selection of lubricating oil is crucial for the safe operation of equipment; And in the process of using lubricating oil, comprehensive monitoring of its performance changes should also be carried out to achieve reasonable lubrication and ensure the safe operation of equipment for a long period of time.

Traditional oil analysis techniques include the detection of more than ten analytical indicators such as kinematic viscosity, extreme pressure, flash point, acid value, moisture content, pour point, pH value, mechanical impurities, ash content, residual carbon, and corrosion testing. Although the accuracy of the analysis results is high, the analysis operation is very complicated and can only indirectly reflect the degradation and decay of the oil from the performance changes of the lubricating oil. Among them, only kinematic viscosity, extreme pressure, and pour point have a certain correlation with machine performance, while other indicators may not be related to them. They are only meaningful for specific raw materials, processing techniques, and additives. In other words, the physical and chemical properties of the oil are qualified, but its performance may not necessarily be qualified.

In fact, when the physical and chemical indicators are analyzed normally, equipment accidents often occur due to poor performance of additives or additives in the lubricating oil used, excessive friction elements, and other reasons.

Chongqing Dingneng Oil Filter Manufacturing Co., Ltd. TYG series high viscosity lubricating oil filter is a purification and filtration equipment specifically designed for 150-680 # high viscosity lubricating oil and gear oil, developed on the basis of TYA lubricating oil vacuum filter platform. Widely used in the fields of machinery, metallurgy, mining, petroleum, chemical industry, power, railway, etc., it can purify various high viscosity lubricating oils, effectively remove water, impurities, water-soluble acids or bases, amino acids, waste gases, etc. from the oil, improve oil quality, restore lubricating oil viscosity, flash point and performance. Ensure the normal operation of the hydraulic system, power system, and lubrication system.

Purification principle:

The filtration of high viscosity oil mainly requires overcoming several technical difficulties, such as poor fluidity, difficulty in oil inlet, filtration blockage, and poor vacuum separation effect. Dingneng Company has independently developed high-pressure suction circulation heating technology, which can easily raise the temperature of high viscosity oil to around 50 ℃, improve the fluidity of the oil, and then purify the oil through three-dimensional flash evaporation, coalescence and water separation, multi-stage filtration.
