Abstract
The invention discloses a dual-channel shaft vibration monitoring protection instrument which comprises a display device, a sensor and an external circuit, wherein a vibration speed sensor can measure absolute vibration amplitude of bearings of various rotary machines and monitor vibration in vertical and horizontal directions of the rotary machines, and is further particularly applicable to the machines with ball bearings, more vibration of the bearings in the machines can be transmitted onto housings for performing continuous measurement and protection on the rotary machines, and the monitoring instrument is particularly applicable to motors, compressors, fans and other situations, which need to measure a large number of vibration points.
Description
Technical field
The present invention relates to the mechano-electronic field, especially binary channels shaft vibration monitor protection appearance.
Background technology
At present; Vibration monitoring protection appearance is the indispensable monitor protection equipment of large rotating machinery (like steam turbine, blower fan, compressor, motor) device. the signal of input is from SZ-6 type magnetoelectric velocity transducer; Can carry out the watch-keeping and the measurement of absolute vibration to rotating machinery device bearing shell. it has two kinds of structures of single phenotype CZJ-B2 in framework mount type and self charged source selective. and this monitor protection appearance is fit to the system design of middle-size and small-size rotating machinery device TSI, can be widely used in enterprises such as electric power, machinery, chemical industry, metallurgy.But, the current monitor protection equipment that is to use do not have power on, the detection of power loss function, can not effectively work if detect protection equipment, can not in time send signal so that operating personnel in time find and remedy.
Summary of the invention
The present invention for solve the monitor protection appearance can not detect power on, the power down function, provide a kind of
Binary channels shaft vibration monitor protection appearance comprises outer circuit, sensor and eddy current probe, on sensor, installs reliable power supply, on power supply, connects eddy current probe.
According to embodiments of the invention, described power supply all passes through lead with current vortex and is connected on the outer external circuit.
According to embodiments of the invention, anodal and anodal connection when described power supply is connected with eddy current probe, negative pole is connected with negative pole.
The invention has the beneficial effects as follows: on vibration monitoring protection appearance, reliable source of power is installed; Be connected with eddy current probe on the power supply; Have power on, the detection of power loss function, when instrument sudden power or energized, its testing circuit sends signal; Cut off alarm circuit, can suppress the false alarm of instrument effectively.
Description of drawings
The present invention will explain through example and with reference to the mode of accompanying drawing, wherein:
Fig. 1 is a wiring 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.
Binary channels shaft vibration monitor protection appearance as shown in Figure 1 comprises outer circuit and sensor, on sensor, installs reliable power supply 1, on power supply, connects eddy current probe 2; Described power supply 1 all passes through lead with eddy current probe 2 and is connected on the external circuit; Anodal and anodal connection when described power supply 1 is connected with eddy current probe 2, negative pole is connected with negative pole.The present invention is equipped with reliable source of power on vibration monitoring protection appearance, be connected with eddy current probe on the power supply, have power on, the detection of power loss function; When instrument sudden power or energized; Its testing circuit sends signal, cuts off alarm circuit, can suppress the false alarm of instrument effectively.
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.
