Cooling Oil Cooler Manufacturer

Tubular Oil Cooler Utility Model Patent∶ZL 2014 2 0456485.0

Please provide the Chinese content to be translated.. Application and Features∶

（1Purpose

Turbines, fans, coal mills, pumps, and marine propulsion systems in industrial and mining enterprises all require oil coolers for the lubrication of large and medium-sized machinery. Based on the advantages of similar products, our company has conducted extensive experiments on the vibration of the oil-side laminar flow in the heat exchange tubes, successfully developing a new type of tubular oil cooler.

（2Product Structure and Working Principle

The tubular cool oil cooler operates with the characteristic that oil flows through the shell side and water through the tube side. The heat transfer coefficient on the oil side outside the tube is [insert coefficient value here] times that of the inside tube side.120-10The thermal resistance is primarily on the oil side. This equipment replaces the traditional arch baffles with swirl guide vanes, with the main principle being that the cooled oil enters the shell of the cooler through the oil pump, guided by the swirl guide vanes to rotate forward. As it rotates, the oil washes along the circumference of the pipes. The structural parameters of the pipes are the result of optimized selection through multiple comparative tests, offering excellent performance and safety in use, making it an ideal auxiliary equipment for steam turbine units.

（3Product Features

The tubular oil cooler has the following advantages compared to other types of coolers:∶

1. High heat transfer efficiency is a key feature of the plate-type cool oil cooler.2-3Multiple

2.Tightly structured∶Its compactness is comparable to plate heat exchangers.1-2Multiple;

3.Low oil resistance due to the use of swirl guide vanes, with the oil entering as tangential flow, which is beneficial for fluid operation.

4.Long service life, easy installation and maintenance∶The heat exchanger tubes have minimal thermal expansion stress, thus eliminating common issues like cracking and leakage. Installation and maintenance are convenient due to the continued use of the tube-shell structure.

3Selection Guidelines

A wide variety of turbine types are designed by domestic and international turbine manufacturers. Based on extensive data collection, our company has compiled a selection scheme for various turbine oil coolers, as shown in the table. If customers have special usage requirements, please contact our company. V. Installation of the oil cooler∶

1Preparation before installation

Coolant Cooler is pre-tested before shipment0.6mpaHydrostatic test required. However, prior to installation, the provisions of the "Technical Specifications for Construction and Acceptance of Electric Power Projects (Turbine Generator Set Chapter)" should be followed.∶“Cold ink side should be operated under working pressure1.5Double the hydrostatic test pressure retention5No leakage for minutes.

2Coolant Chiller Installation∶

（1The cooler support is mounted on a pre-prepared bracket and can reliably meet its dynamic and static load requirements.

（2Due to the change from an arch-shaped baffle to a swirl guide plate, the cold oil cooler's oil inlet should be in the clockwise direction; do not install it backward.
