Customized production of shell and tube type oil cooler

Pipe-type Cool Oil Cooler Utility Model Patent∶ZL 2014 2 0456485.0

One. Application 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 machinery. Based on the advantages of similar products, our company has conducted extensive experiments on the vibration of 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 oil flowing 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 bow-shaped baffle with a swirl guide plate. The main principle is that the cooling oil, after being pumped into the shell of the cooler, follows the guidance of the swirl guide plate and rotates forward. As it rotates, the oil also washes along the circumferential direction of the pipes. The structural parameters of the pipes are the optimized results from multiple comparative tests, offering excellent performance and safety for use. It is 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.Tightly structured∶Its compactness is comparable to plate heat exchangers.1-2Multiple;

3.Low oil resistance due to the use of swirling baffles, where the oil enters as a tangential flow, conducive to fluid operation

4.Long lifespan, easy installation and maintenance∶The heat exchange tubes have minimal thermal expansion stress, thus avoiding common issues like cracking and leakage. Additionally, the tube-shell structure facilitates easy installation and maintenance.

3Selection Guidelines

Turbine models vary widely among domestic and international turbine manufacturers. Based on extensive information collection, our company has compiled various ordering and selection schemes for 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

Cooling oil exchanger pre-delivery0.6mpaWater pressure test is required. However, before installation, the provisions of the "Technical Specification for Construction and Acceptance of Electric Power Projects (Turbine Generator Part)" should be followed.∶“Cold oil ink side should be operated under working pressure1.5Triple water pressure test maintained5No leakage for minutes.

2Coolant Cooler 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, the cold oil cooler's oil inlet should be in the clockwise direction; do not install it backward.
