1. Purpose
The lubricating oil of large and medium-sized mechanical equipment such as steam turbines, fans, coal mills, water pumps and ship power in industrial and mining enterprises cannot be separated from the tubular oil cooler. On the basis of absorbing the advantages of similar products, our company conducted a large number of experiments on the disturbance of laminar flow on the oil side by heat exchange tubes, and finally successfully developed the latest tubular oil cooler
2. Product structure and work Principle
The flow characteristics of the tubular oil cooler are still that oil passes through the shell side and water passes through the tube side. The heat transfer coefficient of the outer oil side of the tubular oil cooler is the heat transfer coefficient of the inner tube, and the thermal resistance is mainly on the oil side. The tubular oil cooler equipment changes the traditional arcuate partition into a cyclone guide plate. The main principle is that the cooling oil passes through the shell side of the oil cooler and rotates forward with the guidance of the cyclone guide plate. The oil is washed along the circumferential direction of the tube while rotating. The structural parameters are the result of optimization through many comparative tests. It has excellent performance, safe and reliable use, and is an ideal auxiliary equipment supporting product for steam turbine units
Product features of three-type oil cooler
Tubular oil cooler Compared with other types of oil coolers, it has the following advantages
, high heat transfer efficiency which is twice that of plate oil coolers
, compact structure, and its compactness is twice that of plate heat exchangers
, oil The resistance is small due to the use of swirling guide plates, and the oil enters into tangential flow, which is conducive to fluid operation and long service life. It is easy to install and detect. The thermal expansion stress of the heat exchange tube is small, so there are no common heat exchange expansion and leakage problems. . Because it is still a shell and tube structure, installation and maintenance are easy.
