Problems solved by technology

[0004] However, in the above technical solution, when the main shaft rotates at high speed at high temperature, there is a gap between the steam turbine rotor and the bearing box hole of the steam turbine unit, and the lubricating oil in the bearing box squeezes and leaks from the gap between the steam turbine rotor and the bearing box hole. Into the external environment, causing pollution to the environment or even hurting people, and the lubricating oil is directly in contact with the air, and the moisture and dust in the air will be mixed into the oil, so long-term operation will increase the water content and impurities of the lubricating oil. The lubricating oil is polluted, blocking the oil circuit circulation channel, reducing the lubricating oil pressure, and causing the regulation failure of the steam turbine unit

Embodiment 1

[0033] An anti-pollution device for lubricating oil at the output end of a steam turbine, such as figure 1 , comprising a steam turbine rotor 15, a bearing housing 16, a high-pressure cylinder and a circular cylinder cover, one end of the steam turbine rotor 15 passes through the bearing housing 16, and the other end passes through the circular cylinder cover and extends into the cylindrical cylinder body of the high-pressure cylinder, the steam turbine rotor 15 is placed on the ground through the base 6, and the two side walls of the bearing box 16 perpendicular to the axial direction of the steam turbine rotor 15 are respectively fixed with an oil storage box 1 with a semicircular arc in longitudinal section, and the lubricating oil flows from the steam turbine rotor 15 and the bearing box 16 is moved out of the gap to the oil storage box 1 to reduce the occurrence of the lubricating oil in the bearing box 16 leaking from the gap between the steam turbine rotor 15 and the bea...

Embodiment 2

[0040] like figure 2 , in order to make the lubricating oil flow quickly in the output pipe 3, the push pipe 4 is provided with a number of rotating blades 14 on the outer wall near the bearing housing 16. 4 uniformly arrayed in the axial direction, when the rotating blade 14 rotates with the push tube 4, it can generate blowing force on the material in the oil storage box 1 towards the direction of the bearing box 16, so that when the lubricating oil passes through the output tube 3, it can quickly fall into the output pipe 3.

[0041] Working principle: When the lubricating oil flows out from the gap between the steam turbine rotor 15 and the bearing housing 16, the oil storage box 1 blocks the discharge of the lubricating oil into the environment to protect the environment. In addition, the arc-shaped cover arranged on the oil storage box 1 through the connecting piece 2. It can block part of the external air from directly contacting the lubricating oil, and can also prev...

Abstract

The invention discloses a steam turbine output end lubricating oil anti-pollution device, and relates to the field of steam turbines. The device is characterized in that a steam turbine rotor is placed on the ground through a base, two side walls, vertical to the axial direction of the steam turbine rotor, of a bearing box are fixedly provided with an oil storage boxes with semicircular arc-shapedlongitudinal sections, the oil storage boxes are located below the steam turbine rotor, the bearing box is provided with a limiting piece for reducing impurities entering the oil storage boxes, the situation that lubricating oil in the bearing box leaks to the external environment from a gap between the steam turbine rotor and the bearing box is reduced, the environment is protected, and the quality of the lubricating oil is improved.

Description

technical field [0001] The invention relates to the field of steam turbines, in particular to a lubricating oil pollution prevention device at the output end of a steam turbine. Background technique [0002] The steam turbine, also known as the steam turbine engine, is a rotary steam power device. The high-temperature and high-pressure steam passes through the fixed nozzle to become an accelerated air flow and then sprays onto the blades, so that the rotor equipped with blade rows rotates and works externally. [0003] The Chinese patent with the notification number CN208900135U discloses a steam turbine body. Its main technical scheme is: including a bearing housing, a steam turbine rotor and a high-pressure cylinder. The high-pressure cylinder has a cylindrical cylinder body and a circular cylinder cover. One end of the steam turbine rotor extends into the Inside the bearing box, the other end extends into the cylindrical cylinder body of the high-pressure cylinder through...
