Description
Technical field
This utility model relates to a kind of hydraulic generator pilot bearing throw measurement current vortex sensor
Erecting device.
Background technology
Turbine-generator units will carry out the runout of unit after new machine debugging stage and major overhaul and survey
Examination, the unit exceeding standard runout is also performed to dynamic balancing of hydropower unit test, is using non-on-line monitoring system
On the premise of, need the guide bearing position of hydrogenerator is installed current vortex sensor temporarily, to water
The throw data of turbine generator are acquired, to facilitate the runout situation to the hydraulic turbine to be estimated, and profit
In the lookup of hydraulic generator rotor dynamic balance running phase place, the installation of temporary sensory device needs to ensure to pass
Sensor is installed fast, it is easy to dismantles and adjusts, adapts to multiple installation environment, and capacity of resisting disturbance is strong, tool
There is the strongest security reliability.The present invention is directed to the problems referred to above, continuous according to scene repeatedly test assignment
Summarize and innovate, have developed a kind of new installation device of sensor, and obtain in practice
Application, achieves and well applies effect.
Summary of the invention
The purpose of this utility model is to provide a kind of hydraulic generator pilot bearing throw measurement current vortex and passes
The erecting device of sensor.Technical scheme is: this device include sensor stand, current vortex sensor,
Adjusting pad, fishbolt, current vortex sensor is arranged on sensor stand, sensor stand master
Five adjustable height gears it are divided into, adjustment that can be fast for on-the-spot mounting condition in gripper shoe
Different installation gears, adapts to the main shaft test position of differing heights, and this sensor stand can be pacified simultaneously
Fill multiple current vortex sensor, need to install throw sensor and key passes on from one to another at same position simultaneously
The situation of sensor, uses this device can install multiple sensors simultaneously and adjust, solves installation
There is deviation and be difficult to the problem of regulation in multiple sensors time-consumingly length, limited space, phase place, secondary
Fagging has cross and installs gear, can adjust the most at any time according to on-the-spot special test position
Whole, solve test department bit space narrow, and need to avoid there is burr on axis body or key phase being installed
The problem that sheet brings interference.Sensor stand uses instant drying adhesive to be bonded on guide bearing cover plate, and current vortex passes
Sensor is clamped on sensor stand by adjusting pad, and fishbolt carries out Bidirectional clamping to be fixed, will
The signal that current vortex sensor collects transmits to signal analyzer, carries out hydrogenerator runout data
Analysis, and carry out runout assessment of scenario and the dynamic balance running of follow-up hydrogenerator.
Technique effect is as follows:
1. this utility model can effectively improve at guide bearing position installation current vortex sensor
Efficiency and accuracy, it is ensured that the accuracy of test data.
2. this device has the multiple installation environment of adaptation, can install multiple sensor simultaneously, adapts to
Property strong, it is easy to regulation, be convenient to mount and dismount, capacity of resisting disturbance is strong.
Accompanying drawing explanation
Fig. 1 hydraulic generator pilot bearing throw is measured and is assembled schematic diagram with current vortex sensor erecting device
The structure diagram of Fig. 2 sensor stand
Detailed description of the invention
As it is shown in figure 1, the installation of a kind of hydraulic generator pilot bearing throw test current vortex sensor
Device, this device is by sensor stand 1, current vortex sensor 2, adjusts pad 3, fishbolt
4 compositions, current vortex sensor 2 is arranged on sensor stand 1, sensor stand 1 main supporting plate
On be divided into five adjustable height gears, for on-the-spot mounting condition can be fast adjust different
Installing gear, adapt to the main shaft test position of differing heights, this sensor stand 1 can be installed many simultaneously
Individual current vortex sensor 2, at same position simultaneously need to install throw sensor sense mutually with key
The situation of device, uses this device two sensors can be installed simultaneously and be adjusted, solves installation many
There is deviation and be difficult to the problem of regulation in individual sensor time-consumingly length, limited space, phase place, secondary support
Plate has cross and installs gear, can carry out the most freely adjusting according to on-the-spot special test position,
Solve test department bit space narrow, and need to avoid there is burr on axis body or key photograph band being installed
The problem disturbed.Being bonded on guide bearing cover plate by instant drying adhesive by sensor stand 1, current vortex passes
Sensor 2 is clamped on sensor stand 1 by adjusting pad 3, and fishbolt 4 carries out Bidirectional clamping
Fixing, the signal that current vortex sensing 2 collects is transmitted to signal analyzer, carries out hydrogenerator
The analysis of runout data, and carry out runout assessment of scenario and the dynamic balance running of follow-up hydrogenerator.
