Turbine Oil Cooler

Tubular Cool Oil Separator Utility Model Patent∶ZL 2014 2 0456485.0

One. Usage and Features∶

（1Application

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 mechanical equipment. Building upon the strengths of similar products, our company has conducted extensive experiments on the vibration of the oil-side laminar flow in heat exchange tubes, successfully developing a new type of tubular oil cooler.

（2Product Structure and Working Principle

The tubular 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 that of the inside tube side heat transfer coefficient.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, after entering the shell of the cooler through the oil pump, is guided to rotate by the swirl guide vanes. As it rotates, the oil also冲洗es along the circumference of the pipes. The structural parameters of the pipes are the result of optimal selection through multiple comparative tests, offering excellent performance and safety, making it an ideal auxiliary equipment for steam turbine units.

（3Product Features

Pipe-type oil coolers have the following advantages compared to other types of oil coolers:∶

1. High thermal efficiency is a feature of the plate-type cool oiler.2-3Multiple

2.Compact structure∶Its compactness is superior to plate heat exchangers.1-2Multiple;

3.Low oil resistance due to the use of swirl guide plates, with oil entering in a 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 avoiding common issues like cracking and leakage. The tube-sheet structure ensures easy installation and maintenance.

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 various cold oil cooler ordering and selection schemes, as shown in the table. If customers have special usage requirements, please contact our company. V. Installation of the cold oil cooler∶

1Preparation before installation

Coolant cooler is pre-tested before shipment.0.6mpaHydrostatic test required. However, prior to installation, the provisions of the "Technical Code for Construction and Acceptance of Electric Power Projects (Turbine Section)" should be followed.∶“Cool oil side should be at working pressure1.5Multiple times hydrostatic testing, maintained5Zero leakage for minutes.

2Coolant Chiller Installation∶

（1The cooler is supported on pre-prepared brackets and can reliably meet its dynamic and static load requirements.

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