Technical Field

The invention relates to the technical field of hydraulic generators, in particular to a device for preventing an oil-gas mixture at a shaft gap of a horizontal unit of a hydropower station from creeping outwards.

Background

The hydraulic generator is a generator which takes a hydraulic turbine as a prime mover to convert water energy into electric energy. When water flows through the water turbine, water energy is converted into mechanical energy, and a rotating shaft of the water turbine drives a rotor of the generator to convert the mechanical energy into electric energy for output; common hydraulic generators are divided into a vertical structure, a horizontal structure and a perfusion type structure, wherein the common fault of the horizontal unit is that a thrust bearing side is lubricated by thin oil, oil drops or oil-gas mixtures leak outwards from a gap nylon felt of a guide shoe and a large shaft, the oil drops accumulated after long-time operation flow to the ground along the outer wall of a bearing support, and if oil stains flow into tail water, the pollution consequence of a water supply source is serious.

The three-leakage treatment is a core technical problem for water and electricity, the three-leakage is water leakage, gas leakage and oil leakage, if the three-leakage treatment is not good, a standard power station cannot reach the standard, meanwhile, long-term three-leakage can cause energy waste and economic loss, so the oil leakage problem is a big problem which is troubled for a long time by the power station, is a big problem of common oil leakage of horizontal units, and is a problem to be solved urgently by horizontal unit manufacturers in China and even in the world.

Oil leakage at a gap nylon felt between a large shaft and a bearing seat of a guide shoe of a horizontal unit mainly occurs at one side (namely one side with a rotating mirror plate) of a thrust shoe, oil drops or oil-gas mixtures seep from the gap nylon felt between the guide shoe and the large shaft to the outer side of the bearing seat, although the large pivot of the water turbine side is very small, the general large pivot is less than 0.10mm, and after long-term operation, the oil-gas mixtures in a thrust oil tank can be condensed from the gap nylon felt between the guide shoe and the large shaft to the outer side of the bearing seat to finally form oil drops which flow to the ground along the outer wall of the bearing seat; if the oil level is increased for reducing the temperature of the bearing, the oil surface in the bearing seat is increased, so that the oil leakage of the bearing seat is more serious; because the lower half part of the horizontal unit mirror plate is immersed in oil to rotate, the oil in the thrust bearing seat is stirred by the rotation of the mirror plate, and the space at the upper part of the inner cavity of the thrust bearing seat is necessarily oil-gas mixture, a gap between a shaft and the bearing seat is sealed by nylon felt, the oil-gas mixture is blocked, the oil-gas mixture is not feasible from the long-term operation practice, the oil-gas mixture climbs outwards from the gap between the shaft and the bearing seat, and finally, the oil is condensed on the outer wall of the bearing seat to form oil drops to flow to the ground, which is the root cause of the oil leakage at the gap of the nylon felt at the thrust bearing seat side of the horizontal unit.

referring to fig. 7, based on the embodiments 1-2 but with the difference that,

the oil and gas outward climbing prevention mechanism 12 comprises a first oil retaining split 1201 and a second oil retaining split 1202, the first oil retaining split 1201 and the second oil retaining split 1202 form an oil retaining ring, a mounting hole 1203 is arranged at the center of the oil retaining ring, the inner diameter of the mounting hole 1203 is the same as the diameter of the central bearing 3, a handle joint is arranged between the first oil retaining split 1201 and the second oil retaining split 1202, a handle joint bolt is mounted in the handle joint, and the first oil retaining split 1201 and the second oil retaining split 1202 are fixedly connected through the handle joint bolt to form the oil retaining ring; the outer arc sides of the first oil retaining split 1201 and the second oil retaining split 1202 are fixedly connected with fan blades 1204, huge grooves 1205 are formed in the outer diameter edges of the first oil retaining split 1201 and the second oil retaining split 1202, and oil-resistant rubber strips 1206 are fixedly installed in the huge grooves 1205.

The invention also connects with the oil-gas anti-climbing mechanism 12 on the bearing, the oil-gas anti-climbing mechanism 12 includes the first oil-retaining valving 1201 and the second oil-retaining valving 1202, can connect fixedly to form the oil-retaining ring through the function of closing the bolt, set up the mounting hole 1203 in the central position of the oil-retaining ring, the bore of the mounting hole 1203 is the same as diameter of the bearing, thus the oil-retaining ring can be fixed on the bearing steadily, thus the oil-retaining ring can rotate with the bearing together, connect with the fan blade 1204 fixedly on the outer arc side of the oil-retaining ring, the fan blade 1204 is welded on the oil-retaining ring evenly, when the fan blade 1204 rotates with the oil-retaining ring, form the negative pressure in the cavity of the first installation half shell 701 and the second installation half shell 702, make the air outside of the bearing gap can only enter to the cavity of the first installation half shell 701 and the second installation half shell 702, finally discharge from the observation hole 713 on the top of the first installation half shell 701 after the treatment of the oil-gas separator, and the oil-gas mixture of inner chamber can only be circulation in the intracavity forever, and oil-gas mixture can't climb out from the gap between bearing and first installation half shell 701 and the second installation half shell 702, in the use, if want the increase effect of induced drafting, can increase the fan blade 1204 quantity of welding on the oil baffle ring outer arc side as required.

In conclusion, the problem that the oil-gas mixture climbs outwards due to condensation from the gap nylon felt of the guide shoe and the bearing to the outer side of the bearing seat in the use process of the horizontal water turbine generator set is effectively solved by utilizing the mutual matching and promotion among the auxiliary fixing mechanism 10, the oil blocking mechanism 11 and the oil-gas outward climbing prevention mechanism 12.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any person skilled in the art should be considered to be within the technical scope of the present invention, and the equivalent replacement or change according to the technical solution and the modified concept of the present invention should be covered by the scope of the present invention.
