Therefore, in order to ensure the safety of turbine body 1, in other embodiment, devising driving steam turbine, as shown in Figure 3, comprising: the rotating speed Speed control mechanism 3-3 connected successively, turbine body 1 and unpowered from cooling mechanism 3-4; Turbine body 1 connect respectively without electric Displaying Meter 3-5 and exhauster system 3-6;
The parameters such as turbine speed can be shown by Displaying Meter without electricity.Unpowered from cooling mechanism 3-4 can to its bearing implement external power-free cooling, ensure that bearing temperature is in safety range.Rotating speed Speed control mechanism 3-3 is by the valve opening of adjustment steam turbine, and adjustment steam turbine throttle flow, to ensure the invariablenes turning speed of steam turbine.The design of driving steam turbine, ensures that turbine speed reaches 1500r/min rapidly, to provide qualified lubricant oil.
Utilize the steam of the auxiliary vapour header storage of unit as contingency gas sources 3-1, other also can be utilized to store thermogenetic steam as contingency gas sources 3-1, as the admission of driving steam turbine.
After the steam discharge of driving steam turbine can enter the vapour condenser condensation carried, water of condensation discharged and collect.Also steam discharge directly can be introduced main frame vapour condenser.Also by special row's air pipe, steam discharge directly can be entered air.
Driving steam turbine relies on coupling and urgent steam-operating oil pump connection on a shaft, and is jointly installed on steel pedestal.Turbine body 1, coupling, urgent steam-operating oil pump and relevant steam pipework, in-line, oil feed line, relevant valve, relevant instrument etc. form an entirety together with pedestal, can be airtight with outer cover, are installed between steam turbine locomotive.Outer cover open type can not had to install, run yet.
The filler opening of urgent steam-operating oil pump is connected by the main fuel tank of in-line and former power station or the fuel tank that arranges specially.
The oil outlet of urgent steam-operating oil pump, is connected by female pipe of oil feed line and former temperature of power plant steam turbine lubricant oil, and link position is positioned at the female pipe pipeline of the lubricant oil after injector.Check valve is set between urgent fuel pump outlet and the female pipe of former lubricant oil, prevents the refluence of oil.
On the basis of the urgent steam-operating oil pump systems of steam turbine, a kind of urgent steam-operating oil pump remote manual control system of design, as shown in Figure 1, specifically comprises: operating grip 1-1, linkage mechanism 1-2 and on-the-spot coupling mechanism 1-3; Be all mechanical transmission, can use when guaranteeing non-transformer.Operating grip 1-1 is arranged on steam turbine operating platform, and operating grip 1-1 is connected with bar mechanism, and is connected to the startup control valve 1-4 of the female pipe of steamer owner vapour by bar mechanism, on-the-spot coupling mechanism 1-3.Operation and the stopping of steam-operating oil pump can be controlled by connecting rod and on-the-spot coupling mechanism 1-3 by operating grip 1-1, like this can by the operating grip 1-1 of the transferring platform layer 1-5 residing for master-control room, Non-follow control starts the start and stop of oil pump.By urgent steam-operating oil pump remote manual control technique, steam-operating oil pump can be operated at operating platform, ensure more reliably for the operation of in emergency circumstances steam-operating oil pump or experiment provide.On-the-spot coupling mechanism 1-3 can select electromagnetic coupler or other coupling devices.
During urgent steam-operating pump start experiment, the operating grip 1-1 of manually-operable control room layer, acted on the startup control valve 1-4 of the female pipe of steam-operating oil pump systems steamer owner vapour by linkage mechanism 1-2, turbine system leads to vapour, and rotor running drives steam-operating oil pump supply lubricant oil.
When urgent steam-operating oil pump stops testing, the operating grip 1-1 of manually-operable control room layer, the startup control valve 1-4 of the female pipe of steam-operating oil pump systems steamer owner vapour is acted on by linkage mechanism 1-2, take-off device trips, steam-operating valve closing, turbine system leads to vapour to be stopped, and steam-operating oil pump stops supply lubricant oil.
In addition, urgent steam-operating oil pump in start-up course, conveniently steam turbine custom is set, steam turbine is provided with an automatic main throttle valve, and is controlled by solenoid valve 2-1, as the startup control valve 1-4 of the female pipe of steam-operating oil pump systems steamer owner vapour.Upon loss of power, solenoid valve 2-1 action, open automatic main throttle valve, main steam 1-7 enters steam turbine, starts steam turbine.But because system only configures a main inlet throttle-stop valve, reliability is lower.Once this main inlet throttle-stop valve is inoperative, the function of whole system will be lost.
Therefore, in other embodiment, be provided with the startup control valve 1-4 of urgent steam-operating pump start system as the female pipe of steam-operating oil pump systems steamer owner vapour, as shown in Figure 2, specifically comprise: the speed be connected in series opens main inlet throttle-stop valve and speed closes main inlet throttle-stop valve 2-3; Speed is opened main inlet throttle-stop valve and is comprised: the electromagnetic pneumatic linkage valve that solenoid valve 2-1 and pneumatic valve 2-2 combines; Solenoid valve 2-1 is connected with high voltage auxiliary power, and pneumatic valve 2-2 is connected with source of compressed air 2-5.Speed opens main inlet throttle-stop valve and speed pass main inlet throttle-stop valve 2-3 is all arranged on steam turbine admission pipeline, main steam 1-7 flows through that speed opens main inlet throttle-stop valve, speed is closed main inlet throttle-stop valve 2-3 and admission controlling device 2-4 and entered steam turbine inside successively, and turbine body 1 provides speed feedback for admission controlling device 2-4.
Speed open main inlet throttle-stop valve without under outer capacity for normal off status, speed closes main inlet throttle-stop valve 2-3 without being normally open under outer capacity.
When urgent steam-operating oil pump systems is for subsequent use, former temperature of power plant steam turbine is normally run, and solenoid valve 2-1 powers, and pneumatic valve 2-2 air feed, makes spring-compressed, and speed is opened main inlet throttle-stop valve and closed; Manual rotation speed closes main inlet throttle-stop valve 2-3 handle, and speed pass main inlet throttle-stop valve 2-3 opens;
In the stand-by state, remote control solenoid valve 2-1 and then manipulation speed can open main inlet throttle-stop valve, control the start and stop of air pump system;
During former power station dead electricity, have a power failure and solenoid valve 2-1 is opened, pressurized air enters speed and opens main inlet throttle-stop valve, and speed is opened main inlet throttle-stop valve and automatically opened; Steam closes main inlet throttle-stop valve 2-3 through speed and enters steam turbine acting, starts steam turbine;
In running, clash into connecting rod through turbine spindle flyball during hypervelocity and make speed close main inlet throttle-stop valve 2-3 quick closedown.
When urgent steam-operating oil pump normally starts, first the startup of urgent steam-operating oil pump is solenoid valve 2-1 dead electricity, solenoid valve 2-1 dead electricity makes the pressure of vapour pressure pipe change, the pressure of vapour pressure pipe changes thus causes the unlatching of steam-operating oil pump main steam 1-7 pipeline valve, and valve opening degree regulates according to the change of pressure.Such as, in certain urgent steam-operating oil pump systems, in dead electricity situation, solenoid valve 2-1 associates reaction with two main inlet throttle-stop valve through a series of, main steam 1-7 female pipe steam-operating valve opening, steam drives the rotation of steam turbine, and steam turbine drives lubricating pump to provide lubricant oil to power generator turbine.
