Abstract
The utility model relates to a device for lowering water turbine guiding bearing operation bearing temperature which is characterized in that according to the shapes of four outer oil tanks of a water turbine guiding bearing, coolers matched with the outer oil tanks are designed to be attached on the outer oil tanks, guiding pipes are guided from a unit main water supply pushing force water supply pipe and a water draining pipe respectively, the guiding pipes enter a header annular pipe through a cooler header water supply valve, then by heat exchanging of the coolers, heat is taken away by water of the coolers, heat enters a header water draining annular pipe and then is discharged to a unit pushing force water draining pipe through a header water draining valve, and finally heat is discharged to a unit tail water outlet. The guiding bearing temperature of a water turbine can be lowered.
Description
Technical field
The utility model relates to power station equipment cooling technology field, particularly a kind of turbine guide bearing operation watt warm device that reduces.
Background technique
Power station water pilot bearing is the cooling water pilot bearing of self-loopa, bearing liner is blocking type non-with one heart (axle neck and bearing shell decentraction) babbitt metal bearing, totally ten two, bearing is by bearing bracket, lower oil tray, interior oil deflector, oil spill pipe, return tube, externally mounted fuel tank composition, the bearing type of cooling is that self-loopa is cooling, be that deep fat flows to four externally mounted fuel tanks on support cover by the oil spill pipe on bearing bracket, while utilizing the current of Turbine Flow Passage to flow through the outer wall of bearing fuel tank, oily heat is taken away, reduce the temperature of lubricant oil, reach cooling effect, the logical return tube of cooled oil is got back to lower oil tray, and get back in bearing oil groove by 24 spill ports on main shaft axle neck, formation self-loopa is cooling, but because of the water pilot bearing lubrication oil circulation speed of Flows below Shuikou Hydro-power Station fast, actual cooling effect is poor, deep fat through externally mounted fuel tank is kind uncolled, be back to fast again in the fuel tank of water pilot bearing, cause the operation Wa Wengao of bearing, when summer, move 70.9 DEG C of Gao Wawenda.
Model utility content
The purpose of this utility model is to provide a kind of turbine guide bearing operation watt warm device that reduces, and can reduce the Wa Wen of the guide bearing of water turbine.
This device is characterised in that: comprise
cooler, this cooler designs according to the shape of four externally mounted fuel tanks of turbine guide bearing, and is attached on externally mounted fuel tank;
Total endless tube, draws respectively a conduit from unit is main for hydraulic thrust water pipe and waste pipe, enters this total endless tube through the total water supply valve of described cooler; And
Total draining endless tube, the water after described cooler heat exchange is sent into this total draining endless tube, and always drain valve drains into unit thrust waste pipe, finally drains into unit tailrace outlet.
In the utility model one embodiment, described cooler comprises that four groups of import and export all configure valvular delimitation order group cooler.
In the utility model one embodiment, described delimitation order group cooler passes through flange connect by a long cooler, a short cooler.
In the utility model one embodiment, described conduit is steel pipe.
In the utility model one embodiment, also comprise air bells exhauster, be arranged at described water turbine thrust stand place.

Please continue referring to Fig. 2, Fig. 2 is the utility model framework working principle schematic diagram, draw respectively Φ 50 seamless steel pipes from unit is main for hydraulic thrust water pipe and waste pipe, enter total endless tube through total water supply valve 2253 valves of supercooler, then guide to four groups of coolers from four direction respectively, after heat exchange, heat is taken away by the water of cooler, enter total draining endless tube, then drain into unit thrust waste pipe by total drain valve 2254 valves, finally drain into unit tailrace outlet.Every group of cooler passes through flange connect by a long cooler, a short cooler, and every group of cooler imported and exported and joined valve 2253-1, a 2254-1, as delimitation order group cooler.
table 1: operation watt warm record chart before and after water pilot bearing cooler puts into operation
table 2: before and after cooler puts into operation, operation oil temperature and water are led throw data
From the record data of upper table, we can clearly know, the input of the utility model technology can obviously reduce a watt temperature, improve the stability of water pilot bearing work.
The foregoing is only preferred embodiment of the present utility model, all equalizations of doing according to the utility model claim change and modify, and all should belong to covering scope of the present utility model.
