Embodiment approach

[0035]This example discloses a method for preventing oil mist leakage. As the most basic implementation of the present invention, it mainly includes the following steps:

[0036] A. An inner cavity 4 for accommodating cold air is provided on the main body 3 of the oil tank cover, so that the oil mist near the bottom of the main body 3 of the oil tank cover exchanges heat with the cold air in the inner cavity 4, and is condensed into oil droplets and returned to the oil tank 6 in;

[0037] B. Set the main body 3 of the oil tank cover on the main shaft 1, make the main body 3 of the oil tank cover and the main shaft 1 cooperate with each other to form the condensation chamber 2, and set communication between the condensation chamber 2 and the inner cavity 4, so that the cold air in the inner cavity 4 can spread to In the condensation chamber 2, the oil mist rising along the main shaft 1 is condensed into oil droplets and returned to the oil tank 6 to prevent the oil mist from le...

Embodiment 2

[0041] This example discloses a method for preventing oil mist leakage, as a preferred embodiment of the present invention, that is, in Example 1, the main body 3 of the oil tank cover includes a first oil tank cover 3.1 and a second oil tank cover 3.2, the steps A also includes setting a heat insulation layer 8 on the first oil tank cover 3.1, selecting aluminum alloy materials to process the second oil tank cover 3.2, and then making the first oil tank cover 3.1 and the second oil tank cover 3.2 cooperate with each other to form an inner cavity 4. Set a sealing structure at the radial connection between the first oil tank cover plate 3.1 and the second oil tank cover plate 3.2, so that the inner cavity 4 is in a sealed state; Step B also includes the top of the condensation chamber 2, the main shaft 1 and the main body of the oil tank cover 3. A gap 9 is provided at the connection to facilitate the circulation of cold air; a comb-tooth seal 10 is provided at the bottom of the...

Embodiment 3

[0043] This embodiment discloses an oil tank cover structure to prevent oil mist leakage, as a basic implementation of the present invention, such as figure 1 , mainly includes the oil groove cover main body 3 arranged on the main shaft 1, the oil groove cover main body 3 includes the first oil groove cover plate 3.1 and the second oil groove cover plate 3.2, the first oil groove cover plate 3.1 and the second oil groove cover plate 3.2 and the main shaft 1 mutually Cooperate to form a condensation chamber 2; the first oil tank cover 3.1 and the second oil tank cover 3.2 cooperate with each other to form an inner cavity 4 for containing cold air and communicating with the condensation chamber 2, the first oil tank cover 3.1 and the said The radial connection of the second oil tank cover plate 3.2 is sealed, and the inner cavity 4 is in a sealed state; the main body 3 of the oil tank cover is provided with a cooling source 5 for providing cold air for the inner cavity 4 and crea...

Abstract

The invention discloses a method for preventing oil mist leakage, which relates to the prevention of oil mist leakage of motor equipment. A condensation chamber is set between them to condense the oil mist rising along the main shaft; a cooling source is set on the main body of the oil tank cover to create a low-temperature environment for the inner cavity; a grid-like structure is set at the bottom of the main body of the oil tank cover to change the flow rate of the oil mist and flow direction. This technical solution utilizes the principle that oil mist condenses into oil droplets when it condenses, and uses cold air to condense oil mist, preventing oil mist from overflowing and avoiding equipment and environmental pollution.

Description

technical field [0001] The invention relates to oil mist leakage prevention for motor equipment, in particular to an oil tank cover structure for preventing oil mist leakage. Background technique [0002] At present, most electrical equipment including generators and motors have the problem of oil mist overflow. The main reasons are: [0003] Each motor unit is provided with a guide bearing oil tank at the connecting part of the main shaft and the bearing bush, and the oil tank is filled with lubricating oil. When the guide bearing is in operation, due to the relative movement and mutual extrusion of the contact surface of the main shaft and the bearing bush, heat is continuously generated, resulting in the vaporization of the lubricating oil and oil mist; Do centrifugal movement; the oil mist is thrown from the bearing bush to the oil tank wall, then rises along the oil tank wall, then returns to the main shaft surface along the oblique upward direction of the upper oil t...
