Ngokwefekthri yokuhlanganisa ama-lubricant, ukuhlolwa kwe-viscosity kuyisisekelo sokulawula ikhwalithi nokusebenza komkhiqizo. Kungenzeka ukuthi kuyinto ebaluleke kakhulu yokwenziwa kwazo zonke ama-lubricant.
Uhlaka:
Viscosity directly determines a lubricant's ability to perform its primary functions: reducing friction, preventing wear, and providing effective sealing. An oil with incorrect viscosity can lead to catastrophic equipment failure. If it's too low, it results in metal-to-metal contact and increased wear. If it's too high, it causes excessive fluid friction, higher operating temperatures, and reduced energy efficiency. Precise viscosity testing ensures every batch meets the specified grade (e.g., SAE 10W-30), guaranteeing consistency, reliability, and customer satisfaction.
Key Characteristics:
The key characteristics monitored are Kinematic Viscosity, measured at specific temperatures (like 40°C and 100°C) to define the oil's grade and its resistance to flow under gravity. Secondly, the Viscosity Index (VI) is calculated, which indicates how much the viscosity changes with temperature. A high VI signifies stable viscosity across a wide temperature range, which is essential for modern multi-grade engine and hydraulic oils. Finally, for gear oils and polymers, Shear Stability is vital, testing the oil's resistance to permanent viscosity loss under mechanical stress.
Ngokuyinhloko, ukuhlolwa kwe-viscosity okuqinile akukwazi ukuxoxwa ukuze kuhanjiswe imikhiqizo evikela imishini, iqinisekise ukusebenza kahle, futhi yakhe igama leph planta lakho lokuphumelela.
