Description
Technical field
The utility model relates to a kind of unit loading type lubricating fitting that is used for steam turbine.
Background technique
Concerning the steam turbine power generation unit, lubricating fitting is similar to people's blood circulation system and nervous system, is serving as effect lubricated, that cool off, control and seal, and its proper functioning is the necessary condition that guarantees the turbine system proper functioning.In order to keep steam turbine continuous high speed running, not only need a large amount of oil lubricate and cooling bearing, and needs incessantly the higher oil of supply pressure guarantee the regular event of speed control system and protective gear.The steam-turbine lubrication device that generally adopts as shown in Figure 1 at present, main oil pump 23, filter 24, oil cooler 25, spill valve 26, jacking(oil) pump 27, AC Lub oil pump 28, the direct current emergency bearing oil pump 29 that comprise main fuel tank 20, injector 21, start oil pump 22, turbine spindle drives, the vacuum dehydration type reconditioner (not shown) that is external in main fuel tank, be provided with stephanoporate steel plate filter screen 30 in the main fuel tank of injector intake side, main fuel tank 20 is provided with return tube; When steam turbine moves under rated speed, the required whole oil of main oil pump 23 supply lubricating fittings; Pressure oil one tunnel from main oil pump 23 enters the mechanical overspeed trip device, and another road enters main fuel tank 20 and provides pressure oil for injector 21; An oily part of discharging from injector 21 supplies main oil pump 23 suction ports, and another part passes through oil cooler 25, filter 24 for bearing of turbo generator set oil; AC Lub oil pump 28, direct current emergency bearing oil pump 29 are stand by pumps of main oil pump 23, so that keep the female pipe of lubricant oil oil pressure when startup, shutdown and contingent.When steam turbine normally moved under rated speed, after setting up suitable lubrication pressure, all the other pumps were in shut down condition; Any shutdown or contingent cause that lubrication pressure reduces to when adjusting 0.076～0.08MPa, and AC Lub oil pump 28 drops into, and supply with required whole in oil of unit; Direct current emergency bearing oil pump 29 is stand by pumps of AC Lub oil pump 28.But this device has the following disadvantages:
1, owing to adopts injector 21, injector mainly is made up of nozzle, mixing chamber, throat and diffuser, because when oil passes through nozzle, speed increases, this high speed oil passes through mixing chamber, in mixing chamber, produce a low pressure area, make oil from fuel tank, suck mixing chamber, brought into injector throat by high speed oil then; The oil that sucks from main fuel tank 20 equals the oil mass of main oil pump supply nozzle import approx, and oil enters the diffusion pipeline section by throat, can convert the pressure energy in the speed of diffuser oil; Because oil can produce jet noise by the confined space at a high speed, the speed of diffuser oil can convert the pressure energy to, has a large amount of energy losses, and efficient is low, generally speaking for integrated operation efficient is 15%, and duration of work noise height.
2, stephanoporate steel plate filter screen 30 exists that filter precision is low, purifying effect is poor, cleaning is inconvenient, must shut down the shortcoming of reprocessing, cause lubricant oil oil turbidity test generally relatively poor, can not satisfy the requirement of big capacity unit for a long time, easily cause the frequent plucking wearing and tearing of turbine generator unit shaft neck, as once occurring in during the overhaul because of regulus is entered in the bearing with lubricant oil with clearing up behind the vertical pipeline section of fire weldering cutting generator rear bearing oil inlet pipe, cause bearing shell and axle journal heavy wear, the scene that is forced in is carried out turning to axle journal and is handled and change bearing shell; Other has because oil system is unclean, and oil circuit is contaminated, and bearing bush abrasion is serious, and corresponding axle journal plucking can not be set up normal oil film when jacking(oil) pump damages decompression low speed, makes the Start-up and Adjustment time lengthening 7 months.
3, the steam turbine power generation unit is in running, and is employed a large amount of lubricated and regulate oil and be subjected to sneaking under the situation of steam and introduced contaminants at any time, influences the safe operation of steam turbine; Vacuum dehydration type reconditioner is high-efficiency dehydration in a short time, but because lubricating oil system is inevitably sneaked into a large amount of air and moisture, makes that the continuous operating load of system is heavy, and breakdown rate is higher.
The model utility content
