When whole, unscrew the second housing screw, so that being detached between the second housing screw and arc ring, then hand-held operation handle rotates arc
Ring, so that arc ring is formed by specific rotation track and is rotated by the first limit guide post, the second limit guide post, arc
To drive rack to rotate, rack drives the rotation of Level tune frame again, puts on Level tune frame to drive for ring rotation
The rotation for the camera set realizes that the adjustment to camera downward tilt tightens the second compression spiral shell after upper lower angle is adjusted
Nail positions so that the second housing screw snaps onto compress arc ring in the arc-shaped slot of arc ring, so that arc ring can not be after
Continuous movement.By carrying out comprehensive adjustment to camera position, so that the shooting posture of camera is more accurate, camera is clapped
Take the photograph plane to be overlapped with the test plane of centrifugal pump, be more conducive to the subsequent improve and perfect to Centrifugal Pump Design structure, improve from
The design performance of heart pump.
By the ingehious design for the device that rotates in a circumferential direction in the present invention, the adjustment that angle is horizontally arranged to camera is realized, simultaneously
Rotation ring disk electrode can be supported effect to the side of Rotation ring disk electrode again by the supporting element of bottom, so that the dress that entirely rotates in a circumferential direction
The structure set is more stable and firm, while supporting element does not interfere with the rotation of Rotation ring disk electrode again, passes through the design of arc frame
The fine tuning to lower angle on camera may be implemented, and the whole design of arc frame is beautiful, reasonable, will not block the bat of camera
Camera lens is taken the photograph, while may insure the structural strength of entire arc frame again, guides arc ring specifically rotating by limit guide post
Rotation in track, be more convenient for it is actual operate with, convenient for the angle that control camera rotates upwardly and downwardly, pass through setting for horizontal slide rod
The adjustment of camera left-right position may be implemented in meter, and is set by the ingenious of snap fit between sliding panel and horizontal slide rod
Meter adjusts camera upper-lower height by the realization of vertical adjustment column so that the sliding of sliding panel and positioning enhanced convenience are simple,
In conjunction with a variety of position regulative modes, the adjustment to the comprehensive position of camera is realized, to effectively farthest guarantee that camera is clapped
The registration for taking the photograph plane and test plane improves the accuracy of measured value.
Overall construction design of the invention is ingenious rationally, by surveying the booster action of quasi- regulating device, may be implemented to PIV
The adjustment in a variety of directions, angle of camera lens improves PIV's to effectively ensure being overlapped for camera camera plane and tested plane
Accurate testing degree is more conducive to the design level of improve and perfect centrifugal pump, and device so that measurement data is more accurate
Overall construction design it is ingenious rationally, use is easy to adjust, and the overall structure fastness of device is good, effectively ensures PIV camera work

It is formed by specific rotation track and is rotated, for the rotation of arc ring 8 to drive rack 9 to rotate, rack 9 drives water again
The rotation of flat adjusting bracket 11 is realized to drive the rotation for the camera 4 placed on Level tune frame 11 to 4 tilted upward of camera
The adjustment of angle tightens the second housing screw 32 after upper lower angle is adjusted, so that the second housing screw 32 snaps onto arc
Arc ring 8 is compressed in the arc-shaped slot 31 of ring 8 and is positioned, so that arc ring 8 can not continue to move to.By to 4 position of camera into
The comprehensive adjustment of row, so that the shooting posture of camera 4 is more accurate, the test of camera 4 camera plane and centrifugal pump
Plane is overlapped, and is more conducive to the subsequent improve and perfect to Centrifugal Pump Design structure, is improved the design performance of centrifugal pump.
By the ingehious design for the device 2 that rotates in a circumferential direction in the present invention, the adjustment that angle is horizontally arranged to camera 4 is realized, together
When Rotation ring disk electrode 5 effect can be supported to the side of Rotation ring disk electrode 5 again by the supporting element 19 of bottom so that entire circumferential direction
The structure of rotating device 2 is more stable and firm, while supporting element 19 does not interfere with the rotation of Rotation ring disk electrode 5 again, passes through arc
The fine tuning to lower angle on camera 4 may be implemented in the design of shape frame 3, and the whole design of arc frame 3 is beautiful, reasonable, will not
The taking lens of camera 4 is blocked, while may insure the structural strength of entire arc frame 3 again, by limiting guide post pilot arc
Shape ring 8 rotates in specific rotation track, be more convenient for it is actual operate with, convenient for the angle that control camera 4 rotates upwardly and downwardly,
The adjustment of 4 left-right position of camera may be implemented by the design of horizontal slide rod 33, and pass through sliding panel 34 and horizontal sliding
The ingehious design of snap fit between bar 33 passes through longitudinal tune so that the sliding of sliding panel 34 and positioning enhanced convenience are simple
Segmented column 12, which is realized, adjusts 4 upper-lower height of camera, in conjunction with a variety of position regulative modes, realizes the tune to the comprehensive position of camera 4
It is whole, to effectively farthest guarantee the registration of camera 4 camera plane and test plane, improve the accuracy of measured value.
Overall construction design of the invention is ingenious rationally, by surveying the booster action of quasi- regulating device, may be implemented to PIV
The adjustment in a variety of directions, angle of camera lens improves PIV's to effectively ensure being overlapped for 4 camera plane of camera and tested plane
