Why does the lubricating oil in the cigarette machine need to be heated? It is generally not necessary to heat those on regular pumps
The lubricating oil used in cigarette machines is generally VG46. Since these machines operate at high speeds and in high temperatures, the viscosity of the oil increases when its temperature drops. Low oil temperatures can cause sudden cooling of the machine, which affects its operation.
It is related to factors such as the load on the equipment, the clearance between the moving and stationary parts, and the lubrication method. As a heavy-duty, high-speed rotating device, the smoke extractor has high requirements for lubrication. Ordinary pumps do not have strict requirements (but from the perspective of facilitating lubrication, the oil temperature should not be too low either).
The oil used in large-scale machinery has specific requirements; an appropriate viscosity of the oil film is necessary to meet the operating demands of the machinery. To achieve this requirement, it is essential to control the temperature of the lubricating oil as well.
Lubricants for large machinery have specific viscosity requirements; as the temperature drops, the viscosity increases. To ensure proper lubrication of the bearing shells, it is necessary to heat the lubricant.
I agree with the opinion from the second floor: “The smoke extractor is a high-speed device, and it operates at high temperatures. When the oil temperature drops, its viscosity increases; low oil temperatures can cause sudden cooling of the smoke extractor, which in turn affects its operation.” It’s easy to understand why a satellite can be damaged by a small stone
If the oil temperature is too low, it is difficult to form an oil film at the shaft seal
I strongly agree with what was said on floor 8: oil No. 46 has a high viscosity, and it is difficult to form an oil film without heating, which affects the operation of the smoke extractor
