Abstract
The utility model provides a water turbine brake apparatus and belongs to the brake apparatus for the water turbine of a cooling tower. The water turbine brake equipment is characterized in that two single-acting hydro-cylinders are disposed at two sides of the water turbine respectively. Each single-acting hydraulic oil cylinder is characterized in that a piston and a piston rod is disposed in a cylindrical body, a spring is sleeved on the piston rod, end caps are disposed in the front portion and the rear portion of the cylindrical body, the piston rod is connected with one brake head and the single-acting cylinder is connected with an oil tank through an oil pipeline. The oil tank is provided with one-way valves, a manual pump, a throttling valve and a pressure gage. The water turbine brake apparatus creatively utilizes the relative motion of the single-acting hydro-cylinders to control the brake of the water turbine and requires no manual shutdown, thereby improving the working security coefficient of equipment and guaranteeing personal safety on an operator.
Description
Technical field
The invention relates to a kind of water turbine braking device that is used for cooling tower.
Background technique
No matter existing water turbine for cooling tower does not have the braking device maintenance, still refuel to water turbine, operator do not have safety assurance.When especially blowing or during hot and cold convection current, under the effect of wind-force, cause the blower fan autobiography, threaten operator's personal safety.The inactive rear fan of water turbine can't shut down, and operator have to come other blower fan just can stop with wooden stick.This way exists personal safety hidden danger.
Summary of the invention
In order to solve the technical problem of above-mentioned existence, the invention provides a kind of water turbine braking device, improves Safety performance, avoids operation behavior lack of standardization.
The purpose of the invention is achieved through the following technical solutions: a kind of water turbine braking device, it is characterized in that: the single-acting hydraulic jack is installed respectively in the turbine shaft both sides, single-acting hydraulic jack structure is: be provided with piston, piston rod in cylinder body, at upper cover of piston rod spring is housed, front portion, rear portion at cylinder body are respectively equipped with end cap, the brake head is connected with piston rod, and one-way cylinder is connected with fuel tank by pipeline road.
In fuel tank, be provided with one-way valve, hand pump, throttle valve, pressure gauge.
The beneficial effect of the invention: said structure is adopted in the invention; the Relative motion control water turbine brake of utilization single-acting hydraulic jack; need not artificial shutdown; improved the safety coefficient of equipment operation; avoid the potential safety hazard brought because of operation behavior lack of standardization, ensured operator's personal safety.

Fig. 1 is the assembling schematic representation of water turbine braking device.
Fig. 2 is the enlarged view of single-acting hydraulic jack.
Fig. 3 is the fundamental diagram of water turbine braking device.
Embodiment
A kind of water turbine braking device, single-action hydraulic cylinder 2 is installed at the radial symmetric place respectively in turbine shaft 1 both sides, 3, single-acting hydraulic jack 2 comprises cylinder body 21, piston 22, piston rod 23, spring 24, front cover 25, rear end cover 26, in cylinder body 21, be provided with piston 22, piston 22 is connected with piston rod 23, on piston rod 23, be set with spring 24, be provided with front cover 25 in the front portion of cylinder body 1, cylinder body 1 rear portion is provided with rear end cover 26, single-acting hydraulic jack 3 is identical with the structure of single-acting hydraulic jack 2, single-acting hydraulic jack 2, piston rod in 3 respectively with brake 4,5 connect, one- way cylinder 2,3 are connected with fuel tank 6 by pipeline road, are provided with one-way valve 61 on fuel tank 6,63, hand pump 62, throttle valve 64, pressure gauge 65.
The working principle of the invention: when water turbine is out of service: shut throttle valve 64; Start hand pump 62, the oil of fuel tank 6 enters in the hand pump 62 by one-way valve 63, enter in the single-action hydraulic cylinder 2,3 by one-way valve 61, single-action hydraulic cylinder 2,3 promotes Piston Compression spring (313.6N) brake 4,5 near embracing the purpose that turbine shaft 1 reaches brake under the effect of pressure again.When starting, opens by water turbine throttle valve 8, system decompression, and under the effect of single-action hydraulic cylinder inner spring, piston pulling brake 4,5 retreats, and the brake head is opened, and water turbine is given water running.
Claims (2)
