Abstract
The utility model discloses a vibration transmitter with a liquid crystal display function, comprising a main body used for placing a working circuit; wherein a front side of the main body is provided with an LCD (Liquid Crystal Display) digital panel and a connecting port used for connecting an external connection signal line; a periphery of the connecting port is provided with connecting fixing holes used for fixing signal line connecting endpoints; a back side of the main body is provided with a connecting port used for connecting the external connection signal line and connecting fixing holes used for fixing the signal line connecting endpoints; a bottom of the main body is provided with a recess screw hole used for fastening the transmitter. By adopting the vibration transmitter with the liquid crystal display function in the utility model, a user can know a failure condition of equipment in advance by viewing real-time vibration intensity value or displacement value parameters displayed on the liquid crystal on site, so as to immediately take measures to the equipment, thereby reducing maintenance difficulty and reducing maintenance cost.
Description
Technical field
The utility model relates to the energy, chemical industry, medical science, automobile, metallurgy, manufacture, military project, the numerous areas such as research and teaching, be mainly used in monitoring the running status of the device product in these fields, predict in advance the vibration transmitters of the failure condition of equipment, be specifically related to a kind of vibration transmitters with liquid crystal display.
Background technology
Along with the progress of science and technology, contemporary equipment makes rapid progress, constantly towards future developments such as integrated, maximization, serialization, high speed, close mode, robotization, procedure, synthesizations.Improving constantly of equipment complexity coefficient strengthened the maintenance difficulty of enterprise for equipment, and traditional maintenance (corrective maintenance and periodic maintenance) strategy obviously can not adapt to the demand for development of modern enterprise.
In order to solve above-mentioned deficiency of the prior art, the utility model proposes a kind of new solution.
The utility model content
The purpose of this utility model provides a kind of vibration transmitters with liquid crystal display, this can check the failure condition that the real-time vibration severity value that shows on the liquid crystal or shift value parameter are predicted equipment in advance by the scene with the vibration transmitters of liquid crystal display, in order to immediately equipment is taken measures, reduce maintenance difficulties, reduced maintenance cost.
For reaching the foregoing invention purpose, the technical scheme that the utility model adopts is: a kind of vibration transmitters with liquid crystal display is provided, it is characterized in that: comprise be used to the main body of laying operating circuit; Described main body front is provided with the LCD digitizing tablet and is used for connecting the Wiring port of outer signal line; Described Wiring port is arranged with the wiring fixed orifice for fixed signal line connection end point outward; Described main body back is provided with for the connectivity port that connects the outer signal line and is used for the wiring fixed orifice of fixed signal line connection end point, and bottom part body is provided with the recess screw for fastening transmitter.
Preferably, described operating circuit, involving vibrations speed pickup, signal processing circuit, voltage/current conversion circuit and LCD display circuit; Described vibrating speed sensors is connected with the input end of signal processing circuit; The output terminal of described signal processing circuit is connected with the LCD display circuit with voltage/current conversion circuit respectively.
In sum, the vibration transmitters with liquid crystal display provided by the utility model has the following advantages compared to existing technology:

Wherein: 1, main body; 2, LCD digitizing tablet; 3, Wiring port; 4, wiring fixed orifice; 5, screw.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in detail.
-as shown in Figure 1 to Figure 3, this vibration transmitters with liquid crystal display comprises be used to the main body 1 of laying operating circuit; Described main body 1 front is provided with LCD digitizing tablet 2 and is used for connecting the Wiring port 3 of outer signal line; The described Wiring port 3 outer wiring fixed orifices 4 that are arranged with for fixed signal line connection end point; Described main body 1 back is provided with for the connectivity port 3 that connects the outer signal line and is used for the wiring fixed orifice 4 of fixed signal line connection end point, and main body 1 bottom is provided with the recess screw 5 for fastening transmitter.
As shown in Figure 4, described operating circuit involving vibrations speed pickup, signal processing circuit, voltage/current conversion circuit and LCD display circuit; Described vibrating speed sensors is connected with the output terminal of signal processing circuit; The output terminal of described signal processing circuit is connected with the LCD display circuit with voltage/current conversion circuit respectively.
This is with the vibration transmitters of liquid crystal display, the real-time vibration information that will record by the internal vibration speed pickup, by the magnetoelectricity principle vibration signal is converted to weak voltage signals, then by signal processing circuit signal is carried out undistorted amplification, shaping, filtering, make it approach the comparatively sinusoidal signal of rule, again a part is directly shown vibration severity value or shift value at the LCD digitizing tablet by the LCD display circuit, another part converts the 4-20mA electric current to by voltage/current conversion circuit and exports.
In sum, vibration transmitters with liquid crystal display provided by the utility model can be checked the failure condition that the real-time vibration severity value that shows on the liquid crystal or shift value parameter are predicted equipment in advance by the scene, in order to immediately equipment is taken measures, reduced maintenance difficulties, reduced maintenance cost.
Although by reference to the accompanying drawings embodiment of the present utility model is described in detail, should not be construed as the restriction to the protection domain of this patent.In the described scope of claims, the various modifications that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
