Abstract
The utility model relates to an energy-saving air pressure reset brake device of a water-wheel generator. The brake device is provided with a brake cavity and a reset cavity which are communicated with a brake pipeline and reset pipeline respectively; and a two-position and three-way electromagnetic air valve, a pressure display controller and a valve are connected in series between the brake pipeline and the reset pipeline. Air for reset of the brake device comes from exhausted air of the brake pipeline, no special air source is needed so that energy is saved by half, and the volume of an air storage tank for brake is reduced by half.
Description
Technical field
The utility model relates to braking device, and particularly hydroelectric power plant's hydraulic turbine generator comprises break and pipeline thereof with the air pressure braking device that resets.
Background technique
Hydroelectric power plant's hydraulic turbine generator with air pressure reset braking device resetting with pressurized air from power plant's compressed air line or special-purpose gas holder, it is suitable substantially with air consumption with braking with air consumption to reset, and circulation of every braking of break and piston reset need provide pressurized air twice.The hydroelectric power plant has many units to bear peak-frequency regulation and pumped storage task, and the annual mean startup-shutdown reaches thousands of times, and compressed-air actuated consumption is appreciable.
Summary of the invention
The purpose of this utility model provides a kind of energy saving pneumatic braking device that resets.This device only needs pressurized air is provided one time when unit is braked, and does not need power plant that pressurized air is provided again during piston reset.
Realize that this purpose needs following technological scheme;
It is half reseting cavity a of brake chamber that break has brake chamber b and cross-section area, respectively at the braking line and the pipeline connection that resets, braking is connected in series two-position three way electromagnetic air valve DKF1, DKF2, DKF3 pressure indicating ﹠ controlling device P1, P2 and valve 1,2,3,4,5,6,7 with resetting between two pipelines, effect of the present utility model: (1) break resets with gas from the braking line exhaust, mustn't special-purpose source of the gas and energy-conservation half.(2) braking reduces half with volume of gas storage tank.
Description of drawings:
Fig. 1 is the utility model braking line figure.
Embodiment
Embodiment
As shown in Figure 1, the sectional area of break reseting cavity (a) is about the sectional area 1/2nd of brake chamber (b).Braking line is connected in series with three two-position three way electromagnetic air valves between the pipeline with resetting, and function is respectively: the first, electromagnetic air valve DKF1 by the source of compressed air of power plant to the braking line air feed, by braking line pressurized air to the pipeline gas transmission that resets; The second, electromagnetic air valve DKF2 by braking line pressurized air to pipeline gas transmission and the bleeder brake pipeline pressurized air of resetting; The 3rd, electromagnetic air valve DKF3 by braking line pressurized air to the reset pressurized air of pipeline of reset pipeline gas transmission and discharging.The brake-pipe pressure indicating ﹠ controlling device P1 and the loine pressure indicating ﹠ controlling device P2 that resets are that the interior pressurized air of automatic and manual control bleeder brake pipeline is to atmosphere.The manually-operated gate function is respectively: power plant's source of compressed air carries out unit braking (1 to the braking line air feed; 3,4,5; 6; 7 close, and 2 open), (2 close to the pipeline gas transmission that resets by braking line behind the unit brake application stoping; 4 open); (4 close) requires piston reset bleeder brake pipeline pressurized air (6 open) behind the pipeline air pressure balance, discharges the pipeline pressurized air (7 open) that resets behind the piston reset.
Claims (1)
