Description
Technical field
The utility model relates to measuring technology, is for compressor, high speed pump, high speed centrifuge rotary member overspeed testing apparatus.
Background technique
1) existing compressor, high speed pump, centrifuge rotary member (impeller) testing apparatus employing motor carry out speed change by step-up gear and reach at a high speed, then be connected with compressor impeller by the main shaft of step-up gear; Seal ring seal is adopted between compressor and gear-box.The needs that this device efficiency is low, noise is high, vibration is large, complex structure, operating cost are high, gear box oil lubricates the development of modern industry that has greater environmental impacts, cannot meet.
2) existing compressor impeller testing apparatus is made up of motor, step-up gear, seal ring, oil lubrication device, coupling, protective housing, platen, lubrication system etc.
3) the Standard relation of existing compressor impeller testing apparatus:
Finished product common electric machine is connected with shaft joint with the step-up gear of finished product, impeller is connected with the main shaft of step-up gear, fix by parallel key and nut, seal ring between impeller and step-up gear is fixed on gear-box main shaft, again motor, step-up gear are fixed by bolts on platen respectively, finally be connected with step-up gear by lubricating utensil oil pipe, the power line energising of extraction just can running test.
4) testing apparatus cannot vacuumize, and during overspeed test, power will match with actual power loss, consumes energy especially.
Summary of the invention
The purpose of this utility model is to provide one under vacuum conditions to compressor impeller overspeed testing apparatus.
The purpose of this utility model adopts technological scheme, comprise vacuum pipe, vacuum tank, vertical machine, connecting sleeve, L bracket, supporting frame, hydraulic jack, aforesaid vacuum tank be communicated with vacuumize vacuum pipe, there is cover upper-end surface, tank wall is welded with supporting frame and support, cover is welded with L bracket one end, supporting frame described in it is equipped with bearing support, bearing pin is through bearing and L bracket mider hole, on support, device has the hydraulic jack of band oil pipe, and the connecting rod of hydraulic jack is ined succession the other end of L bracket; The upper flange of vertical machine is connected with bolt with at the bottom of the tank of vacuum tank; The rotating shaft cover of vertical machine has connecting sleeve.
The utility model structure is simple, reduces equipment volume, energy-conservation, and decreasing pollution reduces operating cost, easy and simple to handle, improves test efficiency, guarantees the features such as equipment safety operation.
