Abstract

The utility model relates to a water turbine overhaul measurement tool, in particular to a water turbine bottom ring height measurement tool. The tool consists of a blocky gauge stand and a dial indicator which is fixedly arranged on the gauge stand; a contact of a measuring bar of the dial indicator penetrates through the gauge stand; and the dial indicator is positioned by a fixed screw. The novel bottom ring height measurement tool is simple to operate and accurate in measurement; the measurement error can reach 0.01mm accurately; the measurement speed is rapid; the working efficiency is high; the use is simple; and the promotional value is high.

Description

Hydraulic turbine base ring measurement of higher degree instrument
Technical field
The utility model relates to a kind of hydraulic turbine maintenance survey instrument, i.e. hydraulic turbine base ring measurement of higher degree instrument.
Background technology
In the prior art, base ring is important flow passage components of the hydraulic turbine, the lower shaft of guide vanes of water turbine is installed on the base ring, all needs the dismounting base ring when unit maintenance, and the altitude figures before and after the base ring dismounting is particularly important, its variation meeting directly influences the distribution of stator end clearance, elevation is higher if base ring is installed the back, will cause the stator end clearance too small, cause stator close or opening process in jam, cause the fracture of water distributor safety feature break pin, can not the normal running stator.The gap of the upper and lower end face of stator and generally in a millimeter.Should measure its elevation before base ring hangs out, measure its elevation after the installation again, in order to compare, if elevation changes, need hang out base ring and check whether fundamental plane is encased inside impurity, to guarantee base ring dismounting front and back elevation unanimity.The original measurement method is: measure base ring with respect to the elevation of fixed part with calliper before base ring is removed, mark its orientation mark earlier, with the height of calliper measurement base ring surface with these corresponding point, with scriber mark on fixed guide vane is drawn, be called the method for mark again.Measure the base ring elevation with the method again after returning dress, so that check and correction.Its shortcoming is that measurement is inaccurate, and small variation is difficult to reflect, and neither one is data accurately, and it is uneven to cause the stator end clearance to be distributed.
The utility model content
The purpose of this utility model is to provide a kind of simple to operate at above-mentioned deficiency, measures hydraulic turbine base ring measurement of higher degree instrument accurately.
Technical solution of the present utility model is: hydraulic turbine base ring measurement of higher degree instrument is made up of block gauge stand and the dial gauge that is fixed on the gauge stand, and dial gauge measuring staff contact passes gauge stand.Dial gauge is located by standing screw.
The utility model has the advantages that: new base ring measurement of higher degree tool operation is simple, measures accurately.Measuring error can be accurate to 0.01mm, and measuring speed is fast, and high efficiency is used simply, has promotional value widely.
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail.
Description of drawings
Fig. 1 is the utility model structure diagram.
Fig. 2 is the right TV structure sketch of Fig. 1.
Embodiment
Referring to Fig. 1,2, main parts size title: gauge stand 1, dial gauge 2, dial gauge measuring staff contact 3, standing screw 4, base ring 5, seat ring 6.
Referring to Fig. 1, hydraulic turbine base ring measurement of higher degree instrument is made up of block gauge stand 1 and the dial gauge 2 that is fixed on the gauge stand 1, and dial gauge measuring staff contact 3 passes gauge stand.Dial gauge 2 is by standing screw 4 location.The dial gauge precision can reach 0.01mm.
Referring to Fig. 1,2, measuring method: the level of at first adjusting survey instrument before the measurement, earlier survey instrument is placed on the reference platform, adjust dial gauge measuring staff contact 3 and gauge stand 1 bottom surface at grade, with standing screw 4 that dial gauge 2 is fixing then, rotate dial plate and make the minute hand zeroing, be i.e. dial gauge 2 zeroings.In measuring process, gauge stand 1 is placed on the base ring 5, and dial gauge measuring staff contact 3 withstands on (fixed part) on the seat ring 6, read a numerical value, be called measurement of higher degree data before the maintenance, and carry out record.Measure its elevation with the method again during 5 times dresses of maintenance back base ring, so that comparison.The difference of before the maintenance and maintenance back numerical value is called the variation of base ring 5 elevations.Variation is qualified in allowed limits.Exceed allowed band and illustrate then that outward base ring 5 and the faying face of seat ring 6 have impurity, should remove base ring 5 and check faying face, and install again.

Claims (1)
