For the hot standby oil system of large-scale operating equipment, what is the most suitable oil temperature? Is electric heating or steam heating better?
Around 45°C; 40–49°C is the optimal range. Electric heating is recommended. If that’s not possible and steam is readily available, then steam can also be used. However, it is strictly forbidden for steam to enter the lubricating oil system
What was said on the second floor is correct; generally, the oil stations that are set up randomly use electric heaters. If a tube heat exchanger is used instead, it is necessary to prevent leaks from the heat exchanger, which could cause steam to enter the oil system and damage the quality of the oil.
The oil temperature should be kept between 30 and 50 degrees; electric heaters are often used, as they are quite convenient!
Typically, gas stations that are set up randomly use electric heaters to keep the oil temperature between 25 and 28 degrees
45 degrees: electric heating is the best option. It’s needed when starting the vehicle; normal operation means no heating is required if the oil temperature is normal. In the north, heating is used as needed
For large units as well, the speed range and the type of bearings used are important factors; rolling bearings operating at low speeds generally require a lower oil temperature； High-speed sliding bearings require a lower viscosity and a temperature of around 40 degrees, in order to facilitate the formation and stability of the oil film at the bearing site.
