Abstract
The invention relates to a hoisting process for a rotating wheel of a vertical shaft axial flow hydraulic turbine, which comprises the following steps of: 1, arranging a small convex plate at the appropriate position on a main shaft; 2, putting an installed rotating wheel on a platform in an installation room, allowing blades to be in the complete shut-down position, and adjusting the horizontal of an upper flange surface of the rotating wheel by 0.02mm/m; 3, hoisting a combining piece of the main shaft and an operating oil tube, connecting the operating oil tube with an operating oil tube of the rotating wheel, connecting the main shaft with the rotating wheel, and connecting the rotating wheel with a bolt and pretightening; 4, sleeving the combination body into the main shaft after combining a support cover and a flow guiding cone or combining the support cover and the flow guiding cone after sleeving the support cover and the flow guiding cone into the main shaft respectively, and putting the combination body on an upper flange or a rotating wheel cover of a rotating wheel body; 5, arranging a partitioned bearing on the support cover or the flow guiding cone, and arranging a divided clamping ring on the top of the bearing; 6, adjusting the height of combination body of the support cover and the flow guiding cone by using a hoist and conducting the safe and protective action when the combination body is hoisted in a turbine pit integrally; 7, reserving an axial gap between the convex plate on the main shaft in the installation room and the clamping ring, wherein the gap is 2 to 5 millimeters greater than the sum of a reverse machine lift value and a bayonet value of the main shaft, and the value is 2 to 5 millimeters greater than the bayonet value of the main shaft, so that the coupling is convenient; and 8, arranging a hanger, and hoisting the combination body in the turbine pit to be put in place.
Description
Technical field:
The present invention relates to a kind of vertical shaft kaplan turbine runner hoisting.
Background technology
Shown in figure one, the traditional hanging method of vertical shaft kaplan turbine runner is to be provided with suspension eye on every blade, be equipped with carrier ring 6 connection runner suspension attachment spare 4 and parts 12 on the foundation ring or on the runner envelope, so just runner by the suspension eye on the blade, suspension attachment, foundation ring the three link up, reach runner is suspended on purpose in the runner envelope, carrying out hydraulic turbine main shaft then in the machine hole connects with runner, domesticly before remembering the nineties all adopt this lifting mode basically, so that this lifting mode designs use is all very ripe in previous generation.But along with the check of motion unit for many years, pretty troublesome when generally reflection is used, in the machine hole, work under hard conditions, the pit after each runner installs on the flow-passing surface at connecting element 6 places will be burn-on with the iron chains piece, so that runner is level and smooth.Lifting hole(eyelet) on the runner bucket will cover soldering and sealing with shrouding and polish, and before each the use, again this two places weld seam is scalped, suspension attachment could be installed, and more outstanding is serious at welding shrouding place cavitation wear, and cancellation has the lifting mode of lifting hole(eyelet) on blade be imperative.Clear and definite regulation " hole of on runner bucket, should not holding funeral rites " in 2006 new GB/T15468 " water turbine basic fundamental condition ", and all stipulate to be forbidden the hole of on blade, holding funeral rites in the contract of modern water turbine.
Summary of the invention
In order to overcome above-mentioned defective, the purpose of this invention is to provide a kind of vertical shaft kaplan turbine runner hoisting.
To achieve these goals, the present invention adopts following technical scheme:
Vertical shaft kaplan turbine runner hoisting: 1. a small boss is established in the appropriate location on main shaft; 2. at clipping room the runner that installs is placed on the platform, blade is in the complete shut-down position, adjusts the horizontal 0.02mm/m of runner upper flange surface; 3. the sling component of giving of main shaft and operating oil line connects operating oil line earlier with the runner operating oil line, main shaft is connected runner attachment bolt pretension with runner again; 4. inner top cover and deflection cone are combined and be inserted in the main shaft or inner top cover and deflection cone are inserted in the back combination respectively, be placed on the upper flange of web or runner covers; 4. the supporting with piecemeal installs on inner top cover or the deflection cone, and for ease of the installation adjustment of supporting, the top of supporting is provided with the snap ring of branch half; 5. adjust the height up and down of inner top cover and deflection cone fabricate block with cucurbit, be convenient to shaft coupling, when integral body hangs in the machine hole, play the safety guard-safeguard effect simultaneously; 6. an endplay is arranged between boss on the clipping room main shaft and snap ring, this gap add the main shaft seam greater than the machine of oppositely the lifting value of water turbine with 2～5mm, guarantee that back in place runner line of centers will be lower than the installation and design elevation in the machine hole, seam value 2～5mm that this value is greater than main shaft makes things convenient for shaft coupling; 7. loading onto the suspender machine that fabricate block can be hung in cheats in place.
Notice: 1. adopt this hanging method not increase factory building height, but will check, be convenient to adopt each parts to lift order flexibly to factory building height.
Adopt the advantage of above hanging method: 1. on blade, do not have lifting hole(eyelet), do not produce cavitation; 2. not only solve the installation of runner in clipping room work, other is as deflection cone, and inner top cover also once hangs in, and shaft coupling carries out at clipping room, has improved service conditions, and is convenient and swift.3. to not influence of runner sealing, the suspension of former long period is unfavorable to the runner sealing that installs; 4. this hanging method all can conveniently not lifted by the restriction of runner diameter size; 5. do not increase the lift heavy of hoisting crane because the weight ratio of electrical generator this is also big slightly.
Description of drawings
Fig. 1 is a structural representation of the present invention.
The specific embodiment
Further specify below in conjunction with accompanying drawing:
As shown in Figure 1, vertical shaft kaplan turbine runner hoisting is placed on the runner 6 that installs on the platform, and blade is in the complete shut-down position; 2. by the sling component of giving of main shaft and operating oil line 2 of suspender 1, earlier operating oil line is connected with the runner operating oil line, again main shaft is connected runner attachment bolt pretension with runner; 3. inner top cover 4 and deflection cone 5 are combined and be inserted in the main shaft or inner top cover 4 and deflection cone 5 are inserted in the back combination respectively, be placed on the upper flange of web or runner covers 4. supportings with piecemeal and installs on inner top cover or the deflection cone, for ease of the installation adjustment of supporting, the top of supporting is provided with the snap ring of branch half; 5. adjust the height up and down of inner top cover 4 and deflection cone 5 fabricate blocks with cucurbit, be convenient to shaft coupling, when integral body hangs in the machine hole, play the safety guard-safeguard effect simultaneously; 6. between boss on the clipping room main shaft and card, one endplay is arranged, this gap add the main shaft seam greater than the machine of oppositely the lifting value of water turbine with 2～5mm.7. loading onto suspender 1 machine that fabricate block can be hung in cheats in place.
