Description
Technical field
The utility model relates to hydraulic turbine field, especially a kind of ZD661-LH100 type hydraulic turbine repairing auxiliary device.
Background technique
The ZD661-LH100 type hydraulic turbine is the product of China's the seventies, and most products have run more than 30 years even
40 years, causing runner envelope cavitation speed to accelerate due to the operation age is long, water pollution is got worse etc., water dispenser is caused to turn
Wheel serious cavitation erosion, unit vibration is big, output-power fluctuation is frequent, seriously affects the stable operation of unit.It needs periodically to water
The cavitation face of Turbine Runner room is handled and is repaired, and frequent repairing can bring frequent downtime, the too long meeting of downtime
Bring biggish economic loss.
Summary of the invention
The technical problem to be solved by the utility model is to provide a kind of ZD661-LH100 type water wheels machine overhauling auxiliary to fill
Set, can auxiliary repair personnel accelerate reparation to turbine chamber cavitation, processing speed.
A kind of in order to solve the above technical problems, the technical scheme adopted by the utility model is: ZD661-LH100 type water wheels
Machine overhauling auxiliary device, including bracket, the bracket include cross brace and ring support, and ring support is fixed on cross brace
Outside, the cross brace be hollow structure, cross brace pass through ring support, telescopic rod is arranged in cross brace；
It is equipped with fan at the middle part of cross brace side, is equipped with infrared heating lamp in the other side of cross brace.
Preferably, the diameter of the ring support is less than the diameter of turbine chamber upper end opening, and telescopic rod stretches out it
The distance between two opposite telescopic rod ends are greater than the diameter of turbine chamber upper end opening afterwards.
Preferably, the side of the ring support is additionally provided with stabilizer blade.
Preferably, the cross brace, ring support and telescopic rod are made of aluminum alloy material.
The utility model provides a kind of ZD661-LH100 type hydraulic turbine repairing auxiliary device, can auxiliary repair personnel add
Reparation to turbine chamber cavitation, processing speed fastly, and more good working environment is provided for service personnel.
Detailed description of the invention
The utility model is described in further detail with reference to the accompanying drawings and examples:
Fig. 1 is the structural schematic diagram of the utility model；
Fig. 2 is the structural schematic diagram of the utility model another side；
Fig. 3 is that the utility model is placed in the structural schematic diagram at turbine chamber upper end opening；
Fig. 4 is that the utility model packs up the structural schematic diagram after telescopic rod.
Specific embodiment
As shown in Figs. 1-2, a kind of ZD661-LH100 type hydraulic turbine repairing auxiliary device, including bracket, the bracket include
Cross brace 1 and ring support 2, ring support 2 are fixed on the outside of cross brace 1, and the cross brace 1 is hollow structure,
Cross brace 1 passes through ring support 2, and telescopic rod 3 is arranged in cross brace 1；Wind is equipped at the middle part of 1 side of cross brace
Fan 4 is equipped with infrared heating lamp 5 in the other side of cross brace 1.
Preferably, the diameter of the ring support 2 is less than the diameter of turbine chamber upper end opening, and telescopic rod 3 stretches out
The distance between two opposite later telescopic rod ends are greater than the diameter of turbine chamber upper end opening.Telescopic rod stretches out
Afterwards, the present apparatus can be placed at the circular open of runner envelope.
Preferably, the side of the ring support 2 is additionally provided with stabilizer blade 6.The present apparatus can be laid flat and ground by stabilizer blade 6,
Convenient for storage.
Preferably, the cross brace 1, ring support 2 and telescopic rod 3 are made of aluminum alloy material.Aluminum alloy materials
Light-weight, intensity needed for can satisfy the present apparatus, and have certain corrosion resistance.
It is dry to runner envelope working face first when being repaired to runner envelope, then be chemically treated with dilute sulfuric acid, make
Surfacing removes impurity, can generate a large amount of acid gas in the process, endanger the health of service personnel, as shown in figure 3, using this
Device dispels the indoor acid gas of runner, can protect the health of service personnel, mention using fan to being blowed in runner envelope
High overhaul efficiency；Then runner envelope is repaired with materials such as epoxy mortars again, repairing opens infrared heating after completing
Lamp 5 shortens the drying time of patching material.Surface polishing is completed after surface is absolutely dry, it is ensured that surface is smooth.Such as Fig. 4 institute
Show, when not in use, telescopic rod can be packed up.
The above embodiments are only the optimal technical scheme of the utility model, and are not construed as the limit for the utility model
System, the technical solution that the protection scope of the utility model should be recorded with claim, the technical solution recorded including claim
The equivalents of middle technical characteristic are protection scope.Equivalent replacement i.e. within this range is improved, also in the utility model
Protection scope within.
