Abstract
The utility model provides a brake of a hydroelectric generating set, which is suitable to use for the dead halt braking of the small-sized horizontal hydro-turbo generating set under 1000 kilowatt. The brake adopts a mechanical type and has the main technical characteristic that a handwheel drives a guide screw and a cap nut to apply force and a series of interlock tribute rods feed force. Ultimately, a brake moment applied to the end surfaces of the two sides of a flywheel and enlarged by myriad times is obtained to finish the braking process. The brake has the main characteristics of simple structure, low fabricating cost, reliable work, flexible operation, safety and strong adaptability and can flexibly adjust structure dimension according to the concrete form of the hydroelectric generating set.
Description
The utility model relates to a kind of hydraulic generator unit break, and it is applicable to that various horizontal hydrogenerator group work is shut down braking usefulness below 1000 kilowatts.
Present known small-sized water turbine cluster engine does not all match the shutdown braking device, thus generally just adopt wooden stick as the shutdown instrument, this will easily cause hydraulic turbine main shaft radially, move axially with the damage of bearing and be absolutely unsafe.In recent years also occur to use manual oil brake, but this kind pattern leaks and make work unreliable and cost is high because of easily producing pressure oil, be difficult to maintenance and popularization is very slow.
It is a kind of cheap and braking is reliable, flexible operation, convenience, be difficult for the hydraulic generator unit break of generation fault that the purpose of this utility model promptly will provide, and it can be realized the safety brake of small hydro turbine group and can generally promote.
Technical solution of the present utility model is to adopt mechanical type, drives the braking moment of a series of Bars bar transmissions realizations to the both ends of the surface outer edge part of water turbine flywheel by nut, screw mandrel, operated by handwheel, and moment can increase as required gradually.
Concrete structure of the present utility model such as accompanying drawing provide.
Fig. 1 is a structural drawing of the present utility model.This break comprises wear-resisting braking plate 1, braking plate fixed tray 2, supporting base 3, brake rod 4, pivot pin 5,8,10, transmission Bars bar 6, supporting axle 7, connecting rod 9, the company's of dragging piece 11, thrust plane bearing 12, drive screw 13, transmission set screw nut 14, handwheel 15, frame 16, flywheel 17.When rotating handwheel such as desire produce and brake then revolver handwheel 15, this moment, drive screw 13 was promptly left-handed, the company's of dragging piece 11 promptly moves and impels connecting rod 9 to promote transmission Bars bar 6 circles to two side shiftings and rotate around supporting axle 8 to handwheel 15 directions, at this moment brake rod 4 promptly drives braking plate 1 and applies braking moment to flywheel 17 and finish braking process under the promotion of transmission Bars bar pivot pin 5, on the contrary but brake off then.
Break is respectively formed the size of constitutional detail and can be formulated according to the concrete model of water turbine, and each supporting shaft etc. has relative movement place should be grease-added.Supporting axle 7, supporting base 3 and transmission set screw nut 14 bases, with bolt in can adjust the braking centre distance frame 16 on, frame 16 can combine with bolted on connection with No. 10 channel-section steels and 12 millimeters thick steel plates, it can be adjusted the centre distance of 1 of two braking plate according to the difference of the thickness of different model water turbine flywheel.Revolve spiral marking connection about adopting respectively between two braking plate fixed trays 2 and the brake rod 4 in addition, be easy to change the braking plate that is worn.
Claims (2)
1, a kind of hydraulic generator unit break is characterized in that: adopt threaded screw rod by the handwheel application of force, multistage Bars bar transmission reinforcement is finally at the heightened disc type brake of moment of braking plate fixed tray (2) and braking plate (1).
2, hydraulic generator unit break according to claim 1 revolves spiral marking connection about it is characterized in that adopting between left and right sides braking plate fixed tray (2) and the brake rod (4), is easy to change the braking plate that is decreased.
