Abstract
The invention discloses an axial vibration transmitter system, which comprises an axial displacement transmitter (1) and an electric eddy probe (5). In the system, faults of various rotary machines can be found at the early stage through axial positions of inner rotors of various rotary machines relative to fixed parts and differential expansion variation; and a standard current signal of 4-20mA is output and is transmitted to a PLC (Programmable Logical Controller)/DCS (Distribution Control System), a DEH (Digital Electro-Hydraulic Control System) and the like.
Description
Technical field
The present invention relates to the mechano-electronic field, especially a kind of axial displacement transducer system.
Background technology
At present, vibration transmitters is that traditional vibration transducer, precision measurement circuit are integrated, and has realized the high precision Vibration-Measuring System, and this product can directly be connected use with systems such as PLC, DCS.Vibration transducer, vibration transmitters, integrated vibration transmitters mainly are installed on the bearing cap of various rotating machinery devices (like steam turbine, compressor, motor, blower fan and pump etc.), but measuring vibrations speed or Oscillation Amplitude.It is the transmitter that is produced the output signal by the motion coil cutting magnetic line, only need supply with the power supply of DC24V when therefore having work, installs, safeguards characteristics such as easy.Extensively model is used for cogeneration plant, cement mill, water pump works, grinding machine equipment, paper mill, machine works, blower fan factory, coal mine machinery etc.But various rotating machinery inner rotator are also inapplicable with the supervision of the difference variable quantity that expands with respect to the axial location of fixed part.
Summary of the invention
The present invention must keep watch on inapplicable problem with respect to the axial location of fixed part with the difference variable quantity that expands to various rotating machinery inner rotator in order to solve present technology; A kind of axial displacement transducer system is provided for this reason; Comprise axial displacement transmitter 1 and eddy current probe 5, shaft vibration transmitter 1 is connected through external cable 3 with eddy current probe 5.
According to embodiments of the invention, described external cable 3 is connected with the interior circuit of axial displacement transmitter 1 through rotary socket 2.
According to embodiments of the invention, described eddy current probe 5 is kept watch on axle 4 with quilt and is directly contacted, and under the user mode, eddy current probe 5 contacts with quilt supervision axle 4.
The invention has the beneficial effects as follows:
Owing to adopted the connected mode of axial displacement transmitter and eddy current probe, wherein eddy current probe directly contacts with the supervision axle is non-, and is convenient, flexible during use, can also one-object-many-purposes.
Description of drawings
The present invention will explain through example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is an axial displacement transducer system wiring diagram of the present invention;
Fig. 2 is an axial displacement transmitter synoptic diagram of the present invention.
Embodiment
Disclosed all characteristics in this instructions, or the step in disclosed all methods or the process except mutually exclusive characteristic and/or the step, all can make up by any way.
Disclosed arbitrary characteristic in this instructions (comprising any accessory claim, summary and accompanying drawing) is only if special narration all can be replaced by other equivalences or the alternative features with similar purpose.That is, only if special narration, each characteristic is an example in a series of equivalences or the similar characteristics.
Like Fig. 1, axial displacement transducer system shown in Figure 2, comprise axial displacement transmitter 1 and eddy current probe 5, shaft vibration transmitter 1 is connected through external cable 3 with eddy current probe 5; Described external cable 3 is connected with the interior circuit of axial displacement transmitter 1 through rotary socket 2; Described eddy current probe 5 is kept watch on axle 4 with quilt and is directly contacted, and under the user mode, eddy current probe 5 contacts with quilt supervision axle 4; Owing to adopted the connected mode of axial displacement transmitter and eddy current probe, wherein eddy current probe directly contacts with the supervision axle is non-, and is convenient, flexible during use, can also one-object-many-purposes.
The present invention is not limited to aforesaid embodiment.The present invention expands to any new feature or any new combination that discloses in this manual, and the arbitrary new method that discloses or step or any new combination of process.
