Structure And Working Principle Of Lubricating Oil Cooler

  The lubricating oil cooler is a tube-and-tube heat exchanger, which is a kind of oil cooling equipment commonly used in power systems. The use of this Structure and working principle of lubricating oil coolerequipment can achieve heat exchange between two liquid media with a certain temperature difference, thereby reducing the oil temperature. Turbine oil cooling can ensure the normal operation of equipment such as steam turbines. The main components of the lubricating oil cooler are the upper and lower water chambers, the casing piping and the oil-filled pipeline. The casing is connected to the water inlet and outlet pipes, the oil inlet and outlet pipes, the drainage pipe, the oil drainage pipe, the exhaust pipe, and the thermometer base.

  Closed cooling water enters the oil cooler through the top end cap of the oil cooler, and then flows in small tubes inside the oil cooler. Countless small cooling water pipes are fixed by partitions distributed inside the oil cooler. The oil cooler is divided into several small spaces by the partitions. The lubricating oil flows in an S shape outside the cooling water pipes. This arrangement can increase effective heat exchange area to improve cooling effect.A cooling water chamber is formed at the bottom of the oil cooler. Lubricating oil and cooling water are separated and sealed by two O-rings (stern tubes) and a copper bed.
