The structure
The flow characteristics of tubular oil cooler are oil passing through shell and water passing through pipe. The heat transfer coefficient of the oil side outside the pipe is 1/10-1/20 of that of the heat transfer coefficient inside the pipe, and the thermal resistance is mainly on the oil side.
Principle of
This equipment changes the traditional bow separator to the cyclone guide plate. The main principle is: the cooling oil passes through the shell of the oil cooler, and rotates along with the cyclone guide plate, and the oil is washed along the tube circumference while rotating. The structural parameters of the tube are the results of multiple comparative tests.
Product Features
Compared with other types of oil coolers, tubular oil coolers have the following advantages:
1, high heat transfer efficiency is 2-3 times that of plate oil cooler;
2, compact structure, its compactness for plate heat exchanger 1-2 times;
3, small oil resistance: due to the use of cyclone guide plate, oil into the tangential flow, conducive to fluid operation;
4, long service life, convenient installation and detection: the heat exchange tube thermal expansion stress is small, so there is no common heat exchange tube expansion, leakage problems. Because it is still shell and tube structure, convenient installation and maintenance.
Selection of products
This product series is specially designed for condensing steam turbines and various heating steam turbines in thermal power plants. It can also be used for the lubrication of boilers, water pumps, coal mills and suction fans of power machinery in industrial and mining enterprises, and for the cooling of power oil.

Installation
1. Preparation before installation: hydraulic test of 0.6mpa before the oil cooler leaves the factory. However, before installation, it should be in accordance with the provisions of "Technical Specifications for Construction and Acceptance of Electric Power Construction" (Steam turbine) :" water pressure test should be carried out on the side of the oil cooler at 1.5 times the working pressure, and no leakage should be kept for 5 minutes. If the wind pressure test is carried out, the pressure should be the working pressure ".
2. Installation of the oil cooler :(1) the oil cooler is supported on the pre-prepared support, and can reliably meet its dynamic and static load requirements.(2) Because the arch separator of the support is changed to the cyclone guide plate, the oil inlet direction of the oil cooler is clockwise, do not install it in the opposite direction.
