Smooth characteristics of the power 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 æ·™ æ·™ æ·™ 芎茫 芎茫 芎茫 æº²è›Šé«Ÿè° è¯µ æº²è›Šé«Ÿè° è¯µ æº²è›Šé«Ÿè° è¯µ æº²è›Šé«Ÿè° è¯µ æº²è›Šé«Ÿè° è¯µ æº²è›Šé«Ÿè° è¯µ æº²è›Šé«Ÿè° è¯µ æº²è›Šé«Ÿè° è¯µ èƒ èƒ.

4. Low freezing point; good low temperature fluidity.
5. High flash point; evaporation.

Tubular waterproof lights are waterproof, corrosion-proof and dust-proof. The respirator design quickly balances the pressure difference between the inside and outside of the lamp to prevent water and dust from entering the inside of the lamp to ensure the normal operation of the lamp.
Compared with the traditional waterproof lamp, it is more convenient to install. It only needs to open the orange end cap of the Led Tube Light, thread the wires in, and connect the terminals.
Led Tube Light can not only be linkable in series but also Parallel Connection, as shown in the figure below.
There are two installation methods, one is a sling and the other is ceiling installation. There are two types of ceiling installations, one is fixed and cannot be moved, and the other can be rotated 180°.
IP66 LED Tri-proof Light has emergency and sensing functions, which is very suitable for parking lots, warehouses, basements, workshops, etc.
