Abstract
The debugging setting method of a kind of vibration monitoring equipment of the invention, for the vibration detection and protection system to large rotating machinery device；The present invention especially shows output and the setting of alarm signal, the requirement before making equipment meet use, it is ensured that reliable for operation, accurate by setting and debugging preparation to respective sensor.
Description
Technical field
The present invention relates to the vibration monitoring fields of mechanical equipment, and in particular to the vibration detection of large rotating machinery device
With the installation and debugging setting method of protection system.
Background technique
Vibration monitoring is that device is or not various large rotating machineries (such as steam turbine, blower, compressor, motor, pump, gear-box)
The detection that can lack, protection equipment.It and vibrating speed sensors cooperate, and can carry out absolute vibration to rotation mechanism bearing shell
Continuous monitoring and measuring.Have and is exported with the directly proportional electric current of measured value, can be with DCS, PLC system, recording instrument without paper is direct
Connection.When vibration amplitude transfinites, the output of alarm relay switching value contact can be automatically provided.
Existing vibration monitoring equipment has high reliablity, and performance is stablized, and the range of linearity is big, frequency response is wide, accuracy is high, warm
It is good to spend characteristic；The features such as strong antijamming capability.It can be widely used in the enterprises such as electric power, machinery, chemical industry, metallurgy, be suitble to medium and small
The monitoring system of type rotation mechanism designs.
But vibration monitoring equipment, using preceding needing to carry out necessary calibration, setting, it is improper because being arranged otherwise easily to cause, letter
Number false triggering, or detection signal inaccuracy, are unable to reach the function of monitoring, alarm.
Summary of the invention
The object of the present invention is to provide a kind of debugging setting methods of vibration monitoring equipment, solve above-mentioned deficiency.
In order to achieve the above object, the present invention provides a kind of debugging setting methods of vibration monitoring equipment:
(1) first that the matched sensor of respective channel is fixed on a vibration table, it is shielded between sensor and supervisory instrument with two cores
Cable is attached；And ammeter is connected on current output terminal；
(2) 4mA is adjusted；After powering on, by adjusting corresponding potentiometer 1, electric current output is modified, until being 4mA；
It checks gauge outfit simultaneously, by adjusting corresponding potentiometer 2, so that gauge outfit is shown as 000 μm, positive negative error is in a position；
(3) 20mA is adjusted；Shake table frequency is fixed on 60Hz, standard signal is fixed on full scale value position, passes through at this time
Adjusting the output of 3 correcting current of potentiometer is 20mA；Then by adjusting potentiometer 4, gauge outfit is shown, is adjusted to 200 μm, it is positive and negative
Error is in a position；
(4) alarm signal is set, and is resetted.
Preferably, in above-mentioned (4), by changing Oscillation Amplitude, alarm setting value is met and exceeded, whether confirmation alarm is sent out
Out, corresponding relay switching variable output connects electric closure；After completing confirmation, stop vibration, and reset to alarm.
The debugging setting method of a kind of vibration monitoring equipment of the invention, for the vibration inspection to large rotating machinery device
It surveys and protection system；The present invention is by the setting to respective sensor and debugs preparation, the requirement before making equipment meet use, really
It is reliable for operation, accurate to protect.
Specific embodiment
Present invention is mainly used for the vibration detections and protection system to large rotating machinery device, provide a kind of vibration prison
Depending on the debugging setting method of equipment, specific step is as follows.
(1) first that the matched sensor of respective channel is fixed on a vibration table, with two cores between sensor and supervisory instrument
Shielded cable is attached；And ammeter is connected on current output terminal.
(2) 4mA is adjusted；Power on, normal lamp is bright, and electric current output should be 4mA, and if any error, adjustable potentiometer 1 is repaired
It is whole；Gauge outfit shows 000 μm of ± 1 word at this time, if any error, can adjust potentiometer 2 and modifies.
(3) 20mA is adjusted；Shake table frequency is fixed on 60Hz, standard signal is fixed on the position of full scale value, electricity
Stream output should be 20mA, if any error, can adjust potentiometer 3 and modifies；Gauge outfit shows 200 μm of ± 1 words at this time, if any error,
Adjustable potentiometer 4 is modified.
(4) alarm signal is set, and is resetted.
I value of alarming setting: I value button of alarm is pinned, potentiometer 5 is adjusted, gauge outfit is made to show required alarming value；
II value of alarming setting: II value button of alarm is pinned, potentiometer 6 is adjusted, gauge outfit is made to show required alarming value；
Actuation of an alarm inspection；When instrument powers off suddenly or is just switched on power supply, detection circuit issues signal, cutting alarm in time
Circuit can effectively inhibit the false alarm of instrument.It is only powered about 25 seconds or so, alarm circuit just unlocks.
Changing the vibration amplitude of shake table, when being respectively more than alarm setting value, alarm should be acted, and corresponding indicator light is lighted,
Relay switching variable output contact closure.
Remove alarm condition: instrument is once alarmed, it has self-locking function, only when measured value is lower than alarm settings
Value, can remove alarm condition by reset key at this time, and alarm lamp goes out, and corresponding warning output contact disconnects.
Basic principles and main features and advantage of the invention have been shown and described above.The technical staff of the industry should
Understand, the present invention is not limited to the above embodiments, and the above embodiments and description only describe originals of the invention
Reason, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes and improvements
It all fall within the protetion scope of the claimed invention.The claimed scope of the invention is by appended claims and its equivalent circle
It is fixed.
