Problems solved by technology
However, the steam-driven lubricating oil emergency oil supply system is generally set at zero meters, and the control room is generally at the steam turbine operating platform, such as a 12-meter platform. If the operator needs to force the device to start, it is extremely inconvenient, especially in an emergency. Delayed commissioning time

Embodiment Construction
[0027] Below in conjunction with accompanying drawing and embodiment the present invention will be further described:
[0028] Generally, the steam turbine emergency steam-driven oil pump system includes: the emergency gas source 3-1 is connected to the steam turbine body 1 through the steam pipeline, the steam turbine startup control device 3-2, and the steam inlet adjustment device 2-4, and the steam turbine body 1 is connected to the emergency steam-driven oil pump system. Oil pump connection.
[0029] 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.
[0030] 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 image...

The invention discloses a system and a method for remotely and manually controlling an emergency steam-driven oil pump. The system comprises an operating handle, a connecting rod mechanism and a field coupling mechanism, wherein the operating handle is connected with the connecting rod mechanism; the connecting rod mechanism is connected with a start control device which is used for controlling the starting and the stopping of a steam turbine through the field coupling mechanism; a start control valve acting on a steam pipeline of the steam turbine through the connecting rod mechanism and the field coupling mechanism controls the steaming of the steam turbine, and so that the starting and the stopping of the emergency steam-driven oil pump are controlled. The system and the method, disclosed by the invention, have the beneficial effects that when a sudden accident happens, a device can be operated within shorter time, and reaction and operation time of an operator can be further saved.
Description
technical field [0001] The invention belongs to the fields of thermal power generation and atomic energy power generation, and in particular relates to a remote manual control system and method for 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 (including support bearings and thrust bearings) and turning gear of the steam turbine generator set, and take away the main steam Heat generated by conduction, friction and turbulence through the shaft. 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...
