1. Product profile
Oil cooler is a kind of oil cooling equipment commonly used in the power system, the equipment can make two kinds of liquid medium with certain temperature difference, so as to achieve the purpose of cooling medium, ensure the normal operation of power equipment, oil cooler is suitable for power gold, chemical industry, mining, light industry machinery and other departments, in power plant is mainly used for equipment lubricating oil cooling, variable speed system oil cooling, transformer oil cooling and steam turbine oil system, coal mill oil system cycle cooling.
2. Model meaning
3. structural style
The oil cooler is divided into vertical and horizontal types; light tube type; and copper tube and stainless steel. It should be selected correctly according to different occasions, use performance and other requirements.
4. Operating principle of the tubular oil cooler
Water enters the tube from the water chamber, and the oil enters the housing and flows outside the bundle. The turbine oil flowing outside the pipe and the circulating water flowing inside the pipe can exchange heat through the copper pipe wall, so as to cool the turbine oil with water.
5. Product features
1. The heat exchange pipe can use 0.5-0.8mm thin-wall stainless steel pipe to improve the overall heat transfer performance. Under the same heat transfer area, the overall heat transfer coefficient is 2.121-8.408% higher than that of the copper pipe.
2, the pipe can be used copper pipe SHn 70-1 or TP 304, TP 316, TP316L and other high quality stainless alloy steel, so that it has a high hardness, the steel degree of the pipe is also significantly improved, therefore, has a strong high temperature steam impact performance and vibration resistance.
3. After the use of high-quality stainless steel pipe, the inner wall of the pipe is smooth, so that the thickness of the boundary laminar flow bottom layer is thin, which not only strengthens the heat exchange, but also improves the anti-scaling performance.
4. In order to eliminate the welding stress, all stainless steel pipes are heat treated at 1050℃ in the protective gas.
5. All stainless steel pipes are checked by differential pressure, pressure test to 10MPa, no pressure drop for 5 minutes.
6, the use of high-quality stainless steel pipe after the strong chloride ion resistance ability, low equipment cost.
