In measuring tool for the adjustable stator blade angle calibration of pneumatic plant of the present invention, multiple position of mounting hole on zero reference steady arm 1 pre-determine, during installation, can ensure that the inter-stage angle of the stator blade 13 when same rank is in predetermined angular state (or being " zero degree " state).Under predetermined angular state, drive this cascade rotating ring 12 again, by the total indicator reading of the standard meter 2 of angle display more accurate response stator blade angle of release and close angle actual conditions, the calibrated error of final stator blade angle is less, more accurately.
The measuring process that the present invention is used for the measuring tool of pneumatic plant adjustable stator blade angle calibration is as follows:
During stator blade measurement of angle, first zero reference steady arm 1 is installed on Profile For Compressor Stator casing.For 0 grade of angle (as shown in Figure 6, and the high order end shown in Fig. 7), first 0 grade of zero reference steady arm 1 (as shown in Figure 1 to Figure 3) is installed on pneumatic plant zero level interlock ring 12, the cooperation cambered surface of 0 grade of zero reference steady arm 1 is made to fit on the external diameter of interlock ring 12, two second mounting hole 101 (1 cylindrical holes wherein on 0 grade of zero reference steady arm 1, 1 narrow slotted eye) be connected with the pilot hole 14 on interlock ring 12 by the register pin 10 of two little precisions, first mounting hole 102 at another place is connected on the axle journal of adjustable stator blade 13 by a fabricated section 9.Thus, the relative position between zero level interlock ring 18 and zero level stator blade is limited by 0 grade of zero reference spacer 1, according to three position of mounting hole design relations of 0 grade of zero reference steady arm 1, can determine that the inter-stage angle of now zero level stator blade 13 is " zero degree " state.
Again angle display is installed on stator blade 13 axle journal.Same for 0 grade of angle, first independent the mandrel part 5 of band cover tooth to be connected on the axle journal of stator blade 13 to be measured by the internal thread of its lower end, and fixedly to tighten, make it can along with stator blade 13 synchronous axial system; Independent the first joint 601 by rocking arm 16 is installed on mandrel part 5 outer wall and (is located on the shaft shoulder of mandrel part 5 outside by the borehole jack offered at the first joint 601) again, and be clearance fit, do not affect mandrel part 5 freely to rotate; the second joint 602 of rocking arm 16 is fixedly supported on the axle journal of another stator blade 13 at the same level by a fabricated section 9, makes it when stator blade 13 to be measured rotates without circumferential movement; Subsequently other parts (gauge stand 7, adaptor 4 etc.) of angle display are installed on mandrel part 5 and rocking arm 16, make the cover toothed portion of adaptor 4 insert on the cover tooth of mandrel part 5, realize connecting.In addition, will fit completely and be supported on the first joint 601 head shaft shoulder of rocking arm 16 in the lower end of gauge stand 7, when paying special attention to carry out this step, milled screw is in the state of getting loose.
Now, because the inter-stage angle of zero level stator blade 13 is fixed on " zero degree " state by 0 grade of zero reference steady arm 1.Therefore, after angle display is in place, conveniently follow-up measurement of angle, zeroing operation is carried out to angle indicator part, by the dial plate 201 of rotary core shaft member 5 and standard meter 2, make the total indicator reading arrow mark zero-bit of angle display part (not shown), tightening milled screw again makes it hold out against the shaft shoulder of rocking arm 16 first joint 601, thus makes the stator part part (comprising standard meter 2, gauge stand 7 etc.) of standard meter 2 and angle display when stator blade 13 to be measured rotates without rotating in a circumferential direction.
After above-mentioned zero level angle display part has returned to zero, pull down 0 grade of zero reference steady arm 1 and two little precision positioning pins 10 from zero level interlock ring 12, to have affranchised motion to make the zero level ring 12 that links; Now, zero level interlock ring 12 is driven to drive stator blade 13 to rotate, stator blade 13 is with the rotating shaft 202 of moving mandrel's part 5, adaptor 4, shaft coupling 3 and standard meter 2 to rotate again successively, and make the needle deflection of standard meter 2, namely its reading reacts stator blade angle of release and close angle actual conditions.
Subsequently, again according to zero reference spacer part installation steps, 0 grade of zero reference steady arm 1 is installed, checks that whether zero level stator blade 13 inter-stage angle is consistent with zeroing angle before; If twice zeroing angle is consistent, illustrates that angle display and zero reference steady arm 1 have carried out correct installation, measurement and the adjustment of the inter-stage angle of the adjustable stator blade of zero level can be carried out subsequently.
According to above-mentioned installation operating process, other three grades of angle displaies and zero reference steady arms 1 are installed successively respectively.After angle display installation at different levels, adjusting to the right place, the demarcation of 0 ~ 3 grade of adjustable stator blade 13 angle can be carried out, calibrated error can be made less, more accurately.
The present invention is used for the measuring tool of the adjustable stator blade angle calibration of pneumatic plant by the optimal design of self structure, ensure that comprehensive detection precision.Its comprehensive detection precision can be ± 10 ', achieve the technical barrier that design tolerance is the ± pneumatic plant adjustable stator blade cold conditions angle Accurate Calibration of 30 '.Thus above effectively control angle accuracy of detection, for accurately learning that multistage compressor stator matching relationship provides technical support from tracing to the source; And measuring tool structure is simple, easy to operate, be easy to realize.In addition, measuring tool provided by the invention achieves the accurate location with casing as taked arc section laminating interlock ring and pilot hole with the concentric technology of casing.By flexible angle transmission mechanism (the mandrel part 5 of band cover tooth and the bindiny mechanism being with the adaptor 4 overlapping tooth to form) technology, eliminate axis and radial error that measuring tool interior angle transfer components causes because of the factor such as installation deviation, issuable idle motion, improve angle transmitting accuracy.Further, select minimum indicating value be 5 ' High-precision standard instrument achieve accurate transfer and the measurement of blade angle.
The above; be only the specific embodiment of the present invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of described claim.
