Diagonal flow type and tubular, the range for being applicable in head/lift are different.Mixed-flow and the inclained flow type water pump hydraulic turbine are mainly used in big-and-middle
Type hydroenergy storage station, wherein the most widely used is mixed flow pump turbine.It is tubular to be then applied to tidal power station more.
In addition, in the pumping plant that some are equipped with axial-flow pump, also has and to be generated electricity using axial flow pump reversion.
Large capacity hydroenergy storage station head is higher, and pump turbine guide vane end clearance does not have sealing device, is metal
Clearance seal, this controls guide vane end clearance and proposes requirements at the higher level, needs repetition measurement guide vane upper and lower side in unit maintenance every time
Face gap, if unqualified readjusted, when ensureing unit normal operation, guide vane upper and lower end face meets service requirement,
Conventional pilot end of blade face gap adjusting structure is adjustment guide vane shaft end spacer thickness, achievees the purpose that adjust guide vane end clearance, this
When kind structure adjusts guide vane end clearance every time, need to tear open guide vane lifting bolt, end cap pin, end cap fixing bolt, end cap
It removes, takes out adjustment cushion block and the thickness of cushion block is adjusted according to the upper and lower end face Gap Analysis of measurement, then guide vane is utilized to lift spiral shell
Bolt control promotes the height of guide vane, realizes that guide vane end clearance adjusts purpose, adjusting process is time-consuming and laborious, especially in water wheel chamber
Operation is even more difficulty in the confined space.
Invention content
The purpose of this utility model is to be directed to the above shortcoming, provides a kind of pump turbine guide vane end clearance tune
Whole structure.
Scheme is used by the utility model solves technical problem：A kind of pump turbine guide vane end clearance adjustment knot
Structure, including lifting bolt, guide vane teunnion, the guide vane lever being set on guide vane teunnion, the guide vane lever upper end cover is equipped with end cap, in end cap
Portion is provided with through-hole, and end cap periphery is evenly distributed in several mounting holes, pin hole A, is provided on guide vane lever and mounting hole, pin hole A
Matched screw hole, pin hole B, screw hole are arranged in a one-to-one correspondence with mounting hole, and pin hole A is arranged in a one-to-one correspondence with pin hole B, and end cap wears long
Mounting hole is simultaneously locked with the end cap fixing bolt of screw hole screw-thread fit with guide vane lever, is set in pin hole B corresponding pin hole A
Be equipped with pin, guide vane teunnion end set has a threaded hole, lifting bolt lower end wear through-hole and with threaded hole screw-thread fit, outside through-hole
At least two adjusting screw hole of all circumference uniform distributions, is provided with the adjusting bolt with its screw-thread fit in adjusting screw hole, under adjusting bolt
It holds against guide vane teunnion.
Further, the axial line of mounting hole, the axial line of pin hole A are identical as the distance between the axle center of through-hole, through-hole
It is located in mounting hole side.
Further, pin hole A is symmetrical arranged two.
Further, screw hole is arranged 6.
Further, adjusting screw hole is arranged three.
Further, adjusting bolt is carbon steel bolt.
Compared with prior art, the utility model has following advantageous effect：Simple in structure, setting is reasonable, cancels existing knot
The adjustment cushion block of the guide vane shaft end of structure uses adjusting bolt instead and adjusts guide vane end clearance, and gap adjustment is convenient, when gap adjustment without
Component need to be dismantled, adjustment time and maintenance duration are shortened.

Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and detailed description.
As shown in Figs. 1-2, a kind of pump turbine guide vane end clearance adjusts structure, including lifting bolt, installation guide vane
Guide vane teunnion, the guide vane lever that is set on guide vane teunnion, the guide vane lever upper end cover is equipped with end cap, through-hole is provided in the middle part of end cap,
End cap periphery is evenly distributed in several mounting holes, pin hole A, be provided on guide vane lever with mounting hole, the matched screw holes of pin hole A,
Pin hole B, screw hole are arranged in a one-to-one correspondence with mounting hole, and pin hole A is arranged in a one-to-one correspondence with pin hole B, end cap wear long mounting hole and and spiral shell
End cap fixing bolt and the guide vane lever of hole screw-thread fit are locked, and are provided with pin in pin hole B corresponding pin hole A, lead
Rachis end set has a threaded hole, lifting bolt lower end wear through-hole and with threaded hole screw-thread fit, through-hole periphery circumference uniform distribution
At least two adjusting screw holes, are provided with the adjusting bolt with its screw-thread fit in adjusting screw hole, and adjusting bolt lower end is against guide vane
Axis.
In the present embodiment, the axial line of mounting hole, the axial line of pin hole A are identical as the distance between the axle center of through-hole,
