Description

Ezaslosva bzheng tour system (© unit

Railway model relates to% of the field of power engineering,. It is not demanding for turbine construction and can be used in these areas of oil supply and gas turbines.

There are known systems for turbo-unit supply (St. GGGP Ш 1339262 I04QI88, 994785, 616422, МШ 1ЩДа5718), in which reserve units are used to ensure reliable oil supply and turbo-oil supply. The indicated oil supply systems for turbine units have the following common elements: main oil tank, oil feed pumps, reserve capacity (aa |) 1Iiniy tank), gadget device, oil feed and drain device, and cleaning and cooling devices (| Elters, oil: coolers )

° The technical solution was chosen as the closest analogue (рот от от иж иж) мас мас) решение Oil supply system for turbines according to USSR L994785, R01D25 / 20, The system contains a main oil tank connected in series, but an oil tank located below the main one and cushioned through the suction collector, emergency pumps | oil tank, oil coolers, fry, etc. emergency tank communicated with no rhzhnikshsh turbSh8shiny $ zherelivshi piping odssh with holes The drain pipe is connected to p) |; (collector Main oil tank connected also with bearing housings

I’ll consider the following: Every day is insufficient reliability,

The objective of the pre-arranged technical solution is to increase reliability and eco-friendliness. The oil and gas supply is achieved. The desired task is achieved by Teie, which, in order to complete the tour, is connected with the following connection, but the main supply pump and pump are connected, 1 | shySh2 & tank, eat this emergency tank located above the main 6aKa, cHaj6 wives with a hot-water device and is connected by the emergency oil supply line from the turbine unit and the main oil tank is connected by a line to the kyo terash zhodshinnikov, it is wired after ovatelno ustanoozit with the oil cooler in the oil line © godachi EEltr, zhodachi Maoli line from the main tank connected to the line by the second oil Avari cottages; accident line 1 ya zhodacha | I went to the hometown, where is it oiQiaTVGrlfturHui QVO imHTL tfr st Smct mopa shavpsh tsontgytchtl. fnojio, UPDIVN hiansh & and and

The system contains the series-connected joining lines of the oil-feeding line, the main oil tank I, pump 2, oil cooler 3 and located above the main tank I, the emergency tank 4, equipped with a sprinkler device 5 and connected to the emergency jumper line 6 from the cooling tower 7 of the turbine unit Main oil tank I connected by line 8 to the crankcases 9 rail 7 "In line 10 oil

with oil cooler installed | Ш1тр II Line I © of oil from the main tank I is connected to line 6 of the emergency oil pump.

Chazf 12 line av 1, bypass oil supply to the juicers 7, diluted in the emergency tank 4 is equipped with at least one calibrated oterotium 13, The inlet of the overflow device 5 is equipped with a throttle washer 14 and connected by a line 15 to the crankcase 9 of the yoke 7,

The oil supply system in normal operation works as follows: After the turbine unit was operating, the oil of the specified pressure from the main tank I is pumped through line 10 to the oil tank 10 by line 10 and then through the | 1lter II line 6 to the bearing grease 7 and to the emergency tank 4, The excess oil from the emergency tank 4 through pereshchsksk1 line 15 under the throttle through the throttle washer 14 (limiting oil nepeiiycK) of the overflow device 5 "enters the crankcase 9 bearings 7 In the crankcase 9 creates a discharging and ventilating effect, resulting in aerated heated and the contaminated oil is drained into the main tank I.

In emergency operation, for example, when the turbine is switched off (stopping it), the oil to BEHAVIOR 7 is wound from the emergency tank 4 along lines 12 6 and through a calibrated hole 13,

In this way, the failure of the bearings and the turbine unit as a whole is prevented and the economical use of oil is enhanced by 11
