Problems solved by technology

However, the system is automatically put into operation only when the whole plant loses power. Since the emergency oil supply system has been in a non-working state for a long time, it is impossible to grasp the working status of the emergency oil supply system in time.

Embodiment Construction

[0038] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:

[0039] Generally, the steam turbine emergency steam-driven oil pump 5 system includes: the emergency steam source 3-1 is connected to the steam turbine body 1 through the steam pipeline, the steam turbine start control device 3-2, and the steam inlet adjustment device 2-4, and the steam turbine body 1 is connected to the emergency steam The moving oil pump 5 is connected.

[0040] Bearing oil breakage is a serious accident of turbogenerators, which will cause serious damage to equipment, such as wear of journals and thrust discs, burning of supports and thrust bearings, and the resulting collision between rotating parts and stationary parts, and even cause Bearing housing catches fire or explodes.

[0041] Therefore, in order to ensure the safety of the steam turbine body 1, in some other embodiments, a drive steam turbine is designed, such as Figure 4 As ...

Abstract

The invention discloses an experimental system and method of an emergency steam-driven oil pump. The experimental system comprises the emergency steam-driven oil pump of a steam turbine, an external experimental oil tank, a lubricating oil pipe, a check valve and a manual gate; the external experimental oil tank is connected with inlet and outlet lines of the emergency steam-driven oil pump through the lubricating oil pipe; the lubricating oil pipe is connected with the inlet and outlet lines of the emergency steam-driven oil pump to form a self-circulating lubricating oil line; the self-circulating lubricating oil line is provided with the check valve and the manual gate. The experimental system and method has the advantages that the emergency steam-driven oil pump system can be kept in the pre-start state anytime, all aspects of the system are in good condition, the system can run safely and reliably in case that a factory is powered off and that a DC oil pump is unable to start, and a steam turbine system is more reliably ensured.

Description

technical field [0001] The invention belongs to the fields of thermal power generation and atomic energy power generation, and in particular relates to an experimental system and method of an emergency gasoline-driven oil pump. Background technique [0002] The currently used steam turbine lubricating oil systems are AC oil pumps and DC oil pumps. The steam turbine lubricating oil system plays a very important role in the steam turbine system. Its task is to reliably provide qualified lubricating oil to the bearings and barring devices of the steam turbine generator set, and take away the main steam generated by shaft conduction, friction and turbulence. generated heat. When the AC oil pump fails, the DC oil pump supplies lubricating oil to the steam turbine system to ensure the safe operation of the system. However, when there was a unit operation accident before, neither the AC oil pump nor the DC oil pump could cut into the working system in time, resulting in a major a...
