Description
Technical field
The present invention relates to the cooling system of a kind of cooling unit, particularly a kind of hydraulic generator set thrust bearing.
Background technique
Thrust-bearing is one of most crucial parts of hydraulic generator unit, the cooling of watt temperature is the problem that the thrust-bearing design is concerned about most always, the height of its temperature rise is directly connected to the safe operation of unit, for multi-form thrust bearing shoe valve, the type of cooling that adopts is also different, the type of cooling more complicated of large-scale unit, and the type of cooling of Pump for Medium and Small Power Generating Set nearly all adopts following pattern at present: promptly place a semi-ring formula oil cooler in the thrust-bearing oil groove, and total turnover water pipe of oil cooler drawn outside the oil groove, when unit operation, in cooling tube, feed clean water as cooling medium, during the cooling water flow supercooler and the lubricant oil in the oil groove carry out exchange heat, the heat that thrust bearing shoe valve produces is taken out of outside the oil groove, as shown in Figure 1,1 is semi-ring formula oil cooler, and 2 is the oil groove of hydraulic generator unit, and 3 is the thrust-bearing of hydraulic generator unit.The generator set of employing oil cooler must provide the cooling water that certain pressure is arranged of cleaning for unit, also need be equipped with the power water pump circulation means in case of necessity, and cooler also must carry out the cleaning of incrustation scale in use for some time.Lubricant oil is polluted because of a variety of causes infiltration owing to worry cooler, also must increase oil level signal device or auxiliary detection devices such as sensing water content mixed in oil advertiser or sensing water content mixed in oil, with the safety of guaranteeing to move.
Summary of the invention
Purpose of the present invention promptly is to overcome the shortcoming of prior art, and a kind of cooling unit of thrust-bearing of hydraulic generator unit is provided, and it is rational in infrastructure, does not need the cooling water and the power circulating device that clean, does not worry that also cooling water can infiltrate lubricant oil.
Purpose of the present invention reaches by the following technical programs, it comprises air-cooler, on air-cooler, be connected with oil outlet tube and return tube, oil sump tank is the C shape oil gathering from looped well device that is positioned at the hydraulic generator unit thrust collar outside, oil sump tank is inboard near thrust collar, the outside has oil outlet, and oil outlet links to each other with air-cooler; In the hydraulic generator unit on the thrust collar circumference between guide shoe and the thrust bearing shoe valve be provided with nozzle opening; The exhaust outlet of air-cooler links to each other with hydraulic turbine generator unit air channel, and sealing fully.
By top narration as can be seen, the present invention has the following advantages: simple in structure, employing air-cooler carries out cooling processing to thrust-bearing, reduced operating cost, do not need simultaneously cooling water yet and drive the power plant that cooling water is made shuttling movement, this is particularly suitable in the Northwest that cooling water lacks, do not need to detect a series of detection devices whether cooling water infiltrates lubricant oil yet, significantly reduced the equipment input.
Description of drawings

Fig. 2 is a structural drawing of the present invention
Embodiment
The invention will be further described below in conjunction with accompanying drawing: as Fig. 2, the cooling system of hydraulic generator set thrust bearing, it comprises air-cooler 4, on air-cooler 4, be connected with oil outlet tube 5 and return tube 8, oil sump tank 6 is the C shape oil gathering from looped well devices that are positioned at hydraulic generator unit thrust collar 10 outsides, oil sump tank 6 inboard close thrust collars 10, the outside has oil outlet 7, and oil outlet 7 links to each other with air-cooler 4; In the hydraulic generator unit on the thrust collar 10 circumference between upper leading axle watts 9 and the thrust bearing shoe valve 11 be provided with nozzle opening, nozzle opening is for being evenly distributed; The exhaust outlet 12 of air-cooler 4 links to each other with hydraulic turbine generator unit air channel, and sealing fully.
When bringing into operation, in the hydraulic generator unit on the thrust collar circumference between upper leading axle watt and the thrust bearing shoe valve be provided with nozzle opening, nozzle opening is for being evenly distributed, it is a power source, when unit operation, the thrust collar of high speed rotating lubricant oil thrust collar is inboard and that keep off between the oil pipe is sent into oil sump tank, oil sump tank is the C shape oil gathering from looped well device that is positioned at the hydraulic generator unit thrust collar outside, oil sump tank is inboard near thrust collar, the outside has oil outlet, when oil is expired in storage in the oil sump tank, because pressure is arranged, the oil in the oil sump tank is extruded oil outlet, and oil outlet links to each other with external air-cooler, because the acting in conjunction of kinetic energy and potential energy, lubricant oil enters in the cooler, and in cooler by air cooling, produce when cooling medium---air is rotated by rotor, last cooled lubricant oil is got back to oil groove again by return tube under pressure, has finished the circulation cooling procedure of lubricant oil.
According to the size of bearing loss, can determine the quantity and the heat dissipation capacity of cooler, be the design of oil sump tank on the one hand, consider oil mass and flow velocity, and cooperate with intermittence between the thrust collar; Will guarantee the air quantity of cooler on the other hand, we adopt the exhaust outlet with cooler to link to each other with the unit air channel, and strict seal, like this when unit operation, and the hot air of rotor generation and will together be taken out of outside the air channel by the hot air behind the cooler.
