First, the power generation profession:
The main cause of power generation is turbine oil. The turbine oil in operation has the following two major effects: Steam turbine bearings and launches have some heat due to conflicts and high temperature steam; turbine oil continuously circulates to carry this some heat away; so that the temperature of the steam turbine does not exceed a certain temperature value; it has a cooling effect. Turbine oil has an outstanding high-temperature smooth function; it forms an outer layer of oil film on the conflict surface of each transition; it does not directly conflict with each conflict surface; reduces the conflict coefficient; ensures the normal operation of the equipment.
Turbine oil is also called turbine oil; it is made of vacuum oil as smooth material; it is refined by deep refining; it participates in the distribution of additives such as anti-oxidation and anti-rust.
Turbine oil is primarily used for the smoothness of steam turbines, water turbines and gas turbine generators.
Turbine oil quality requirements:
1. Excellent oxidation stability; to ensure less long-term circulation of oil using less oxidized sediment; increase in acid value. 倜 10 years or more (foreign quality brands usually reach 25 years).
2. Excellent demulsibility; easy to separate from water; make the water leaking into the smooth system agile in the fuel tank; to ensure the normal smoothness and cooling effect of the oil.
3. Outstanding viscosity-temperature; to ensure that the bearings of the steam turbine unit can be outstandingly smooth at different temperatures.
4. Excellent rust resistance; to avoid the rust of the speed control system due to the entry of steam and condensate into the system.
5. Outstanding anti-foaming; air bubbles in the work and foaming; excessive foam or not easy to affect the normal circulation of oil.
Second, the power transmission profession:
The primary oil used in power transmission is transformer oil. The transformer oil in operation has the following two major effects: 1. The core and coil of the transformer are immersed in the transformer oil; the air and moisture are blocked; to adhere to the line between the transformer, between the high-voltage coil and the low-voltage coil, between the coil and the subway core; and between the tank walls Insulation; no short circuit and arc.2. In the work, the transformer oil relies on the principle of hot and cold convection; after the cycle; the heat of "copper consumption" and "core loss" is released to the atmosphere; thus the temperature of the transformer is not too high.
Transformer oil quality requirements:
1. Excellent electrical insulation function; high dielectric strength; small dielectric loss angle.
2. Viscosity. (4) 瓤欤 淙 淙 淙 芎茫 芎茫 芎茫 溲蛊髟谠诵 溲蛊髟谠诵 溲蛊髟谠诵 溲蛊髟谠诵 溲蛊髟谠诵 溲蛊髟谠诵 溲蛊髟谠诵 溲蛊髟谠诵 胁 胁.
3. Outstanding oxidation stability; long life.
