Abstract
The utility model relates to a horizontal water turbine with a rearmounted control ring and a split cover plate, which comprises a volute, a runner and a guide blade, and is characterized in that an generator end of the water turbine is provided with the cover plate which has a split structure; and the cover plate at a tail water end of the water turbine is provided with the control ring. The horizontal water turbine has the benefits: a generator and a spindle at the front end of the water turbine do not need to be disassembled when the water turbine is overhauled, and only the control ring and the cover plate at the rear end of the water turbine need to be dismounted, therefore, the whole overhaul process is simple and easy, the precious time is saved, and the overhaul technical difficulty is reduced. Compared with the existing water turbine, for a hydropower station with an installed capacity of 2*5000kW, the horizontal water turbine can improve the annual utilization of the hydropower station by 450 hours, increase income by 2.6 million and reduce overhaul cost by 800 thousand.
Description
Affiliated technical field
The utility model discloses a kind of water turbine, concretely, is at the control ring mounting point of horizontal water turbine and the improvement of cover plate structure.
Background technique
Water turbine is divided into vertical turbine (main shaft is vertical) and horizontal water turbine (main shaft is horizontal) two big classes, in general, because it is little that horizontal water turbine has a volume, compact structure, low and the little advantage of civilwork engineering quantity of cost, so power during in Selection and Design, should preferentially be selected horizontal unit at the Francis turbine within the 8000kw.
The horizontal water turbine control ring of present stage adopts front-located mode, be that control ring is positioned at the generating pusher side, general configuration is, water slug runner in the spiral case, tail water end (rear end) has the cover plate of ring-type in order to sealing, motor side (front end) also has the cover plate of one, the control ring of ring-type is housed on the cover plate, control ring can be realized relatively rotating by a small margin, mechanically actuated by a plurality of connecting rods during rotation changes the guide vane opening of water turbine, to reach the purpose of adjusting by hydraulic turbine discharge, generator shaft passes control ring and cover plate is connected in runner to obtain torque.
Said structure, through for many years facts have proved it is to have higher functional reliability, but also exist unsurmountable shortcoming: runner and stator are enclosed in inside by parts, when needs overhaul, must carry out from front end (motor side), the program of standard is: tear generator open, hang generator, control ring and cover plate are axially hung out along main shaft, tear main shaft open, overhaul again and repair, all reinstall in order again after being over, so not only take a lot of work, and priorly make whole maintenance duration quite very long, for the power station, this leeway means enormous economic loss, in addition, being connected once more because the position of generator has taken place to change of main shaft and runner need be looked for reference for installation again, also increased technical difficulty undoubtedly.
Summary of the invention
The purpose of this utility model provides a kind of control ring postposition and cover plate split horizontal water turbine, to remedy the existing long technical deficiency of water turbine maintenance duration.
The technical solution adopted in the utility model is: control ring postposition and cover plate split horizontal water turbine, comprise spiral case, runner and stator, and it is characterized in that: the generator end at water turbine is equipped with cover plate, and cover plate is for dividing body structure; On the cover plate of the tail water end of water turbine, control ring is installed.
The beneficial effects of the utility model are: water turbine need not to dismantle the generator and the main shaft of front end when maintenance, as long as pull down control ring and cover plate in the rear end, whole maintenance process is not only simple, and saved valuable time, reduced the service technique difficulty, water turbine more in the past is that the power station annual utilization hours can be improved several 450 hours in 2 * 5000KW water power plant for an electric motor power, increase income 2,600,000 yuan, reduce 800,000 yuan of recondition expenses.
Description of drawings
Below by embodiment, and in conjunction with the accompanying drawings the utility model is further described:
Fig. 1 is an assembling generalized section of the present utility model;
Fig. 2 is the rear end schematic representation;
Fig. 3 is the cover plate schematic representation.
Embodiment:
Embodiment:
In the drawings, comprise spiral case 1, runner 2 and stator 3, generator end (front end) is equipped with cover plate 4, and cover plate 4 has been divided into left half plate 5 and right half plate 6 for dividing body structure, and it is draft tube that control ring 7,8 is installed on the cover plate 4 of tail water end (rear end).
With affiliated component processing with after assembling, get final product proper functioning.
When water turbine need overhaul, pull down control ring 7 and cover plate 4 from the rear end and just can carry out, reduction is installed after being over again.The cover plate 4 here can adopt the branch body structure, also can not adopt the branch body structure.
Said process, the parts of motor side (front end) all do not relate to, and this also is innovation soul of the present utility model place.
Because all there is Sealing at the position that relates to of the main shaft of leading portion, when needs overhaul and change these Sealings, need not dismantle generator and main shaft equally, as long as the connection between a left side half plate 5 and right half plate 6 is dismantled, all can operate, the purpose of cover plate 4 distinguish is modes of axially taking off of avoiding in the past, and the motor of just must moving away at that rate is to vacate the position.And cover plate 4 distinguish can to highlight the prerequisite of positive effect be control ring 7 postposition, otherwise simple cover plate 4 distinguish are without any effect.
Claims (1)
1. control ring postposition and cover plate split horizontal water turbine comprise spiral case, runner and stator, and it is characterized in that: the generator end at water turbine is equipped with cover plate, and cover plate is for dividing body structure; On the cover plate of the tail water end of water turbine, control ring is installed.
