Description

Double-fed fan gear box cooling system

The technical field is as follows:

the utility model relates to a double-fed fan gear box cooling system.

Background art:

the design structure deviation of the gear box lubricating system causes that lubricating oil cannot be normally cooled by the heat exchanger, and causes the temperature of the lubricating oil to be too high, thereby causing the temperature of the gear box to be high, alarming and stopping, and losing the generated energy.

The short service life and the high damage rate of the lubricating oil circuit motor are main reasons causing the poor lubrication fault rate of the gear box, the faults of the gear box are reduced, and the working time of the lubricating oil circuit motor needs to be reduced.

An air-cooled radiator of a gearbox is main equipment for oil cooling, and the overtemperature of the gearbox caused by poor radiating effect pipes of the cooler often occurs.

The utility model has the following contents:

the utility model aims at providing a double-fed fan gear box cooling system.

The above purpose is realized by the following technical scheme:

a double-fed fan gear box cooling system, its constitution includes: the lubricating oil outlet of the gear box is communicated with the filter through a communicating pipe, and the communicating pipe is provided with a mechanical pump;

and an extravehicular radiator and a bypass pipeline are also arranged on a communication pipeline between the filter and the air cooler.

According to the double-fed fan gear box heat dissipation system, a lubricating oil outlet of the gear box is circulated to a lubricating oil inlet of the gear box after passing through the electric pump, the filter and the air cooler in sequence.

Has the advantages that:

1. the utility model discloses in original lubricating system's return circuit, increase the mechanical pump, when the gear box rotates, close the electric pump, by the mechanical pump operation, increased oil circulation, lubricated effect is better under the circulation with higher speed.

2. The utility model discloses increase 1 group's extra-cabin radiator, the temperature control valve control pipeline direction, when the temperature was higher than 55 ℃, opened two radiators, when the temperature was less than 30 ℃, oil had only expanded radiating margin through single radiator, increased the heat dissipation effect.

Description of the drawings:

FIG. 1 is a schematic structural diagram of the present invention;

in the figure: 1. an air cooler; 2. an outboard radiator; 3. a gear case; 4. a filter; 5. a mechanical pump; 6. a bypass line; 7. a lubrication system; 8. an electric pump; 9. a communication pipe is provided.

The specific implementation mode is as follows:

example 1:

a double-fed fan gear box cooling system, its constitution includes: the device comprises a gear box 3, an electric pump 8, a filter 4 and an air cooler 1, wherein a communicating pipe 9 is also communicated between a lubricating oil outlet of the gear box and the filter, and a mechanical pump 5 is installed on the communicating pipe;

and an extravehicular radiator 2 and a bypass pipeline 6 are also arranged on a communication pipeline between the filter and the air cooler.

Example 2:

according to the double-fed fan gearbox heat dissipation system in the embodiment 1, the lubricating oil outlet of the gearbox is circulated to the lubricating oil inlet of the gearbox after passing through the electric pump, the filter and the air cooler in sequence.

The working principle is as follows: 1 group of outdoor radiators are added, the direction of the pipeline is controlled by the temperature control valve, when the temperature is higher than 55 ℃, the bypass pipeline is closed, the heat is dissipated through the combined action of the air cooler and the outdoor radiators, when the temperature is lower than 30 ℃, the bypass pipeline is opened, only through the independent air cooler, the heat dissipation margin is expanded, and the heat dissipation effect is increased.

Claims (2)
