Problems solved by technology

At present, when the steam turbine is working, the rotor rotates at a high speed in the cylinder, causing friction between the air in the cylinder and the cylinder, which causes the steam turbine to vibrate, and then generates noise that endangers the health of on-site workers
Aiming at the problem of generating noise during steam turbine operation in the prior art, the present invention proposes a new solution

Embodiment

[0022] like Figure 1~2 As shown, this embodiment provides a safe and low-noise steam turbine, which includes: a rotor 10 and a cylinder 20, the rotor 10 is rotatably connected to the cylinder 20, a lubricating device 30 is arranged inside the cylinder 20, and the The rotor 10 rotates at a high speed so that when the frictional force between the air in the cylinder 20 and the cylinder 20 reaches a set value, the lubricating device 30 automatically injects lubricant into the cylinder 20 to avoid The friction force between the air in the cylinder 20 and the air in the cylinder 20 is too large, thereby reducing the noise hazard, so that the friction force between the air in the cylinder 20 and the cylinder 20 is controlled within the set value and the root cause is eliminated. Vibration causes safety hazards of parts falling off.

[0023] Tested by the inventor, the set value of the friction force is 78N.

Abstract

The present invention provides a safe and low-noise steam turbine. The steam turbine includes: a rotor and a cylinder with a lubricating device inside. The rotor is rotatably connected to the cylinder, and the friction between the air in the cylinder and the cylinder When the set value is reached, the lubricating device automatically injects lubricant into the cylinder. The invention adopts a cylinder with a lubricating device inside, and the rotor rotates at a high speed in the cylinder, so that when the friction force between the air in the cylinder and the cylinder reaches the set value, the friction plate moves, driving the plug head to overcome the spring pressure to leave the plug, and lubricate The device automatically injects lubricant into the cylinder to reduce the friction between the air in the cylinder and the cylinder, thereby reducing the noise hazard.

Description

technical field [0001] The invention relates to the field of steam turbines, in particular to a safe and low-noise steam turbine. Background technique [0002] The steam turbine 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 is sprayed onto the blades, so that the rotor equipped with blade rows rotates and works externally. Steam turbines are the main equipment of modern thermal power plants, and are also used in metallurgical industry, chemical industry, and ship power plant. At present, when the steam turbine is working, the rotor rotates at a high speed in the cylinder, which makes the air in the cylinder rub against the cylinder, which causes the steam turbine to vibrate, and then generates noise that endangers the health of on-site workers. The present invention proposes a new solution to the problem of noise generated during steam turbine operation in the prior art. C...
