Description
Technical field
The present invention relates to steam turbine technology field, specially a kind of steam turbine arbor axis vibration amplitude detection system.
Background technique
Steam turbine is also referred to as steam turbine engine, is a kind of rotary steam power device, and high temperature and high pressure steam passes through solid
Nozzle is determined as being ejected on blade after the air-flow accelerated, makes the rotor rotation equipped with blade row, while external acting.Steam turbine
It is the capital equipment of modern thermal power plant, is also used for metallurgical industry, chemical industry, in ship's powerplant；Steam turbine is energy
Convert steam thermal energy to the external combustion rotary machinery of mechanical work.After steam from boiler enters steam turbine, successively pass through one
The nozzle and movable vane of series of annular configuration, convert the thermal energy of steam to the mechanical energy of turbine rotor rotation.Steam is in steamer
In machine, energy conversion is carried out in different ways, just constitutes the steam turbine of different operating principle.
But there are some drawbacks in use in traditional steam turbine, such as:
Traditional steam turbine when in use, since its internal arbor is in rotary state for a long time, so that arbor and machine
It is easy abrasion mutually between axis fixing piece and generates gap, is easy for occurring when the gap between arbor and fixing piece is larger
Arbor vibration, and the vibration of arbor can accelerate the rate of wear between arbor and fixing piece, it is therefore desirable to real-time control arbor
Gap between fixing piece avoids arbor that the biggish abrasion and breaking-up for shaking and leading to equipment occurs, but in the prior art
Shock sensor is mostly used greatly to the shock detection of arbor, and needs to stop equipment when shock sensor is installed, this
The work that sample can seriously affect power plant causes biggish loss, moreover, traditional detects arbor using shock sensor
Mode situations such as being only able to detect the vibration degree of arbor, can not intuitively detecting amplitude, the frequency of arbor vibration, because
This detection effect is bad.
