Description
Technical field
The utility model belongs to the hydraulic generator unit, relates in particular to a kind of dustless braking device of integrated type of hydraulic generator unit.
Background technique
In hydraulic turbine generator, the generator amature rotary inertia is very big, and startup and shutdown are very frequent, and in order when shutting down generator set to be stopped very soon, generator is provided with braking device.Several breaks of circumference uniform distribution adopt the low-pressure compressed air operation, and when shutting down, pressurized air is squeezed in the break, and brake plunger rises, and the braking flashboard contact generation with brake hoop on being fixed on generator amature and rubs, and makes the rotor brake application stoping.In this braking process, because the generator amature rotary inertia is very big, therefore for making the rotor brake application stoping that (is generally 2min) at the appointed time, braking flashboard and brake hoop will take place to rub consumingly.Fricative heat raises brake hoop and stopping brake plate temperature, braking flashboard and brake hoop simultaneously will be worn, produce brake dust, clean out as untimely collection, will be taken away by the cooling air that the generator inner loop flows, be deposited on iron core and stator and rotor coil surface, pollute coil, increase flowing resistance, reduce insulating property.In the generator in early days, owing to do not design dust collecting system, stator and rotor are seriously polluted, influence unit and normally move, even have an accident.For this reason, the power station has to send someone often go cleaning to safeguard, has increased the workload of unit regular maintenance.Along with the development of power station automation, general all being provided with break is the dust exhaust apparatus that separated type is connected by pipeline in the generator of design in recent years.The effect of this dust exhaust apparatus is the dust that produces when assembling also absorption brake braking by instruction, removes dust after filtering, and clean air is expelled back in the atmosphere.Dust exhaust apparatus generally is made of four parts: collection/dust shield 8, pipeline 7, device for recovering powder 9 and control gear.Various forms of collection/dust shields are to be centered around around the break, form a sealing or semi-enclosed space, and brake dust is enclosed in this space can't disperse.Pipeline is the passage that connects collection/dust shield and device for recovering powder; Blower fan in device for recovering powder rotation back produces negative pressure, makes the sealing or the hemi-closure space of collection/dust shield parcel form a swirling eddy by pipeline, drive brake dust with the air-flow dispatch to blower fan and filtration system, thereby the collecting function of realization dust.Control gear is startup and the operation of controlling device for recovering powder by the instruction that reception power station central control chamber sends.The traditional dust exhaust apparatus and the mounting type of break are seen Fig. 5.Its dust shield is whole airtight big cover, with whole break all cover get up, only in the gap of 5 mm that have an appointment near the part of brake hoop, this gap is both as the personal distance of rotating part and stationary part, again as the suction port of air.Under the effect of negative pressure, air is inhaled into thus from outside to inside, carries the dust that braking process produces, and through piping, is pumped to device for recovering powder, and dust is discharged clean air by media filtration in device for recovering powder.In used in the power station, the break of this structure and dust exhaust apparatus using effect were unsatisfactory.2004 the 9th phases, " Tohoku Electric Power technology " author Zhao Xiangdong, Wang Liyu disclosed a kind of novel Brake Dust Collecting System for Turbine Generator, were the little cover dust collecting system of follow-up-type, and basic structure is formed as shown in Figure 6.Compare with traditional big hood configuration, the difference of the little cover dust collecting system of follow-up-type maximum just is the structure difference of dust shield, it adopts a very little dust shield, be fixed on the outer rim of break keep plate, except in face of one side of brake hoop moving direction, other three limits all are furnished with the ash retaining, constitute " U " shape dust shield structure, the opening of " U " word is the direction that rotary component head-on comes, the air that comes along with rotary component just in time from then on opening enter dust shield, add the suction function of device for recovering powder, dust is sucked away.The bottom of " U " font is an accumulation area, carries dust and compiles herein by the pipeline air that links to each other with device for recovering powder herein, is drawn onto device for recovering powder.The ash retaining is high temperature resistant hairbrush, high temperature resistant hairbrush is fixed on three edges of break keep plate, when unit is braked, rise and fall with brake plunger, the ash retaining contacts with brake hoop when rising, air sucks from the gap location of " U " shape dust shield opening and hairbrush, hairbrush can also prevent the excessive of dust with under the dust brush that sticks on the brake hoop.The dust collecting system advantage of this structure has been the volume-diminished of dust shield, and rate of air sucked in required is corresponding to diminish, the also corresponding reduction of capacity of adapted device for recovering powder.But integrally-built dust collecting system is formed the dust suction unit by a plurality of breaks by multiple-way duct and a device for recovering powder, forms Brake Dust Collecting System for Turbine by many groups dust suction unit again.Dust shield and device for recovering powder remain and are by pipeline that separated type is long-range to be connected.Pipeline is long in actual use, pipeline to prolong journey loss big, the air quantity decay is very big, causes actual effect poor, and pipeline prolongs journey loss air quantity and can't accurately calculate, so will mate more powerful blower fan in the device for recovering powder; Because the space of generator set is narrow and small, long pipeline and a plurality of device for recovering powder take up room excessive simultaneously.Power plant demands developing a kind of hydraulic turbine generator braking dust collecting system that the space is little, pick-up performance is better that takes up an area of urgently.
The model utility content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology, and the dustless braking device of the integrated type that a kind of hydraulic generator unit is provided, brake gear is integral formula with device for recovering powder and is connected, and it is poor to have solved pick-up performance, the piping layout difficulty is taken up an area of the big difficult problem in space.
The utility model for achieving the above object, by the following technical solutions: the dustless braking device of a kind of integrated type of hydraulic generator unit, comprise braking device and device for recovering powder, be connected with the ash retaining on the braking supporting plate edge of braking device, it is characterized in that: described device for recovering powder mainly is made of the ash retaining, air filtering core and the dust-collecting box that set gradually from top to bottom, described device for recovering powder is positioned at the braking device side, the device for recovering powder total height less than the braking device bottom of foundation to the distance between the brake hoop.
Described device for recovering powder mainly by self-priming dust dust-collecting box housing, place fireproof plate, air filtering core and blower fan in the self-priming dust dust-collecting box housing, described self-priming dust dust-collecting box housing top intake grill places on the tangent direction of rotary component rotary motion trace, and be positioned at below the hairbrush ash retaining, fireproof plate is connected successively from top to bottom with air filtering core and places in the self-priming dust dust-collecting box housing, and blower fan places the air filtering core rear.
Beneficial effect: self is provided with device for recovering powder break, is in one-piece connection, and has overcome break separates generation with device for recovering powder shortcoming.The compact structure of dustless braking device, it is poor to have solved pick-up performance, and the piping layout difficulty is taken up an area of the big difficult problem in space.
