Abstract

The invention relates to heat exchange equipment, in particular to a main pump lubricating oil cooler. The heat exchanger is heat exchange equipment developed specially for a nuclear power reactor main pump lubricating oil system. The heat exchanger comprises a barrel body, an upper end cover, a lower end cover, a plate bunch, a connecting flange, pipelines, an inlet flange and an outlet flange, wherein the barrel body, the upper end cover and the lower end cover form a sealed cavity of the heat exchanger, the connecting flange of a rhombic structure is arranged in the middle of the barrel body, the two L-shaped pipelines with discharge oil compensating ports are symmetrically arranged at the two sides of the barrel body, one end of each pipeline is communicated with the barrel body, the other end of each pipeline is arranged on the connecting flange, the inlet flange and the outlet flange are perpendicular to the axial direction of the pipelines and are arranged on the barrel body, and the plate bunch is arranged in the sealed cavity of the barrel body. The main pump lubricating oil cooler is simple and reasonable in structure, high in heat transferring efficiency, and convenient to install and use.

Description

technical field [0001] The invention relates to a heat exchange device, in particular to a lubricating oil cooler for a main pump. The heat exchanger is a heat exchange device specially developed for the lubricating oil system of a main pump bearing of a nuclear power reactor. Background technique [0002] The plate heat exchanger has a history of more than 100 years since its development and appearance. The plate heat exchanger itself has the characteristics of high height, compactness, and convenient maintenance. Its application fields are constantly expanding, and its products have been used in petrochemical, metallurgy, electric power, light industry, food, medicine, ships, offshore platforms and other fields. As people's understanding of plate heat exchangers continues to deepen, plate heat exchangers are more widely used and It is also reasonably applied to the field of nuclear power. Over the years, nuclear power plants at home and abroad have directly used plate heat...
