Abstract
The utility model relates to a water-sealed water retaining ring for a main shaft of a water turbine generator. The characteristics of the water-sealed water retaining ring are as follows: a bearing device is arranged on the main shaft, an oil inlet and an oil return pipe are connected on the bearing device, a water sealing device is arranged on the main shaft, a water inlet pipe and a water return pipe are connected on the water sealing device, and a water retaining ring which is arranged on the main shaft is located between the bearing device and the water sealing device. As the water retaining ring is arranged on the main shaft, water is effectively prevented from flowing to the upstream bearing device along the main shaft, thereby solving the problem that the water enters the bearing cover; moreover, the water-sealed water retaining ring also has the advantages of simple structure, convenient installation and easy manufacturing.
Description
Technical field
The utility model relates to a kind of hydraulic turbine generator main shaft water-stop technology, especially a kind of hydraulic turbine generator main shaft water-stop water holding ring.
Background technique
The main shaft of hydraulic turbine generator is to be supported by bearing means and water sealing device, the structure of water sealing device mainly is to be made of pressure pad water tank, main shaft seal lining and packing box, the I-shaped ring is set between main shaft seal lining and packing box, I-shaped ring both sides are provided with packing, and packing and I-shaped ring are pressed in the packing box by the pressure pad water tank, and packing can closely contact with the main shaft seal lining.Main shaft when operation injection pressure water in the I-shaped ring, the effect that press water can play sealing, cooling and lubricate this moment.Press water is understood some and is flowed in the runner, a part just can flow in the pressure pad water tank, but also have seldom the part can be along a main shaft side shifting upstream, last even may flow in the bearing (ball) cover of bearing means, end cap then is a backflow position of bearing means lubricating oil system, in case there is water to sneak in the bearing (ball) cover, can cause the quality of whole bearing oil to descend, principal axis lubrication is affected.
Summary of the invention
The utility model provides a kind of hydraulic turbine generator main shaft water-stop water holding ring of good water-proof effect for solving the technical problem that exists in the known technology.
The technological scheme that the utility model is taked for the technical problem that exists in the solution known technology is:
A kind of hydraulic turbine generator main shaft water-stop water holding ring, the filler opening that comprise main shaft, be installed in bearing means on the main shaft, is connected with bearing means with return tube, be installed in water sealing device and intake pipe that is connected with water sealing device and return pipe on the main shaft, on the described main shaft water holding ring is installed, this water holding ring is between bearing means and water sealing device.
The utility model can also adopt following technological scheme:
Described water holding ring is that two semi-rings are formed by connecting.
Advantage and the good effect that the utlity model has are:
Because water holding ring is installed on main shaft, this water holding ring is between bearing means and water sealing device, and block water moves along the upstream bearing means of main shaft effectively, has solved the problem of bearing cap water inlet; The utility model also has advantage simple in structure, easy for installation, that be easy to make in addition.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, main shaft; 2, bearing means; 3, water holding ring; 4, water sealing device; 5, seal cartridge; 6, packing box; 7, I-shaped ring; 8, intake pipe; 9, pressure pad water tank; 10, return pipe; 11, return tube; 12, filler opening.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, bearing means 2 is installed on main shaft 1, be connected with filler opening 12 and return tube 11 on the bearing means, water sealing device 4 is installed on main shaft, water sealing device is made up of pressure pad water tank 9, sealing of spindles lining 5 and packing box 6.I-shaped ring 7 is set between main shaft seal lining and packing box, and I-shaped ring both sides are provided with packing, and packing and I-shaped ring be pressed in the packing box by the pressure pad water tank, and packing can closely contact with the main shaft seal lining, plays seal action.Packing box is connected with intake pipe 8, and the pressure pad water tank is connected with return pipe 10, and water holding ring 3 is installed on the described main shaft, and this water holding ring is between bearing means and water sealing device.Described water holding ring is that two semi-rings are formed by connecting, and helps like this installing.Because water holding ring is installed on main shaft, this water holding ring is between bearing means and water sealing device, and block water has solved the problem of bearing cap water inlet along main shaft side shifting upstream effectively; The utility model also has advantage simple in structure, easy for installation, that be easy to make in addition.
