The utility model provides an under bearing and method can be used to various on -the -spot working condition, instant on line measurement, the remaining axial force numerical value of monitoring pump.
Description
Technical field
The utility model relates to the tilting-pad bearing of a kind of pump residual axial force test, and being particularly useful for can the tilting-pad bearing of on-line monitoring axial force.
Background technique
Tilting-pad bearing is made up of the arc tile fragment of 3-5 block or more.Each tile fragment operationally, can along with the load change of rotor automatic swing, around axle journal, form heavy wool contract.Tilting bush not only has larger bearing capacity, low power consumption and can bear the radial load of all directions.The pump of tilting-pad bearing is adopted to there is certain residual axial force when operating and stopping, in order to better monitor its axial force, the detecting method that general employing is direct or indirect.
Direct measurement is by pasting pressure (drawing) foil gauge on tilting-type tile bearing broken tiles, the electrical signal that pressure (drawing) foil gauge receives constantly is transformed by charge amplifier, finally finally obtains residual axial force size from the magnitude of voltage of voltmeter reading electric charges amplifier.Such shortcoming must paste stress section after tilting-type tile bearing broken tiles, just can not dismantle once stickup, and tilting-pad bearing just can not use by secondary.Meanwhile, the wiring reason due to stress section can not directly apply to, on the pump run, can only use in the lab.Output signal is magnitude of voltage, needs to be scaled power, and conversion trouble, directly can not read residual axial force numerical value, use inconvenience.
Indirect inspection is the principle adopting back blade balancing axial thrust, by doing several back blade at the back shroud of impeller, during pump operation, under the effect of these two opposite direction power of axial force that the axial force that pump shaft is transmitted at impeller and static hydraulic pressure force measuring machine give, reach longitudinal balance, do not produce axial displacement.Because its device can eliminate the interference of slide axially frictional force and axial static frictional force automatically, so the axial force that hydraulic pressure force measuring machine gives pump shaft just in time equals moving fluid in pump chamber give the axial force of impeller.Like this, calculate the difference of two manometric readings that static hydraulic pressure dynamometric system connects, just can obtain the size of residual axial force.But the result that this quadrat method is measured is inaccurate, need constantly to revise.Meanwhile, need the back blade that oneself fabrication design is new, indirectly improve cost.
