A little inflammable and explosive Petrochemical Places are lubricated oil/fluid lubricant scene filling operation, are also easy to that safety accident occurs；
Although existing self-acting lubricator can solve defect problem present in manual maintenance, it can accomplish periodic maintenance, it cannot be
The first time of motor failure sign (such as: temperature rise is excessively high, abnormal vibration) is realized at timely oiling maintenance and troubleshooting
Reason, it is still desirable to respective handling is manually carried out, so that there are still the risks such as motor damage and unexpected shutdown.
It is crucial that no matter existing monitoring system or self-acting lubricator, be required to configure additional power supply or
It is external power supply or is battery, in order to simplify the trouble of wiring and improve the convenience that motor uses, usually uses electric power storage
Pond power supply still causes potential risk to the safety in production of enterprise so that being also required to often shut down artificial replacement battery.
In short, can be confessed in the prior art there are no a kind of for motor operating state monitoring system and oiling device
Electricity is able to achieve motor operating state monitoring system and oiling device work asynchronously with motor, is able to achieve online from monitoring and certainly dimension
Shield can realize timely oiling maintenance and failure in the first time of motor failure sign (such as: temperature rise is excessively high, abnormal vibration)
The intelligent electric machine for excluding processing, so that the prior art can't meet the needs of intelligence manufacture and intelligent plant well.

1321 contain clock circuit, thus can be opened certainly by clock setting maintenance period (such as: 1500 hours) by main control singlechip 1321
Dynamic oiling motor 31 carries out automatic oiling, realizes and periodically safeguards certainly；In addition, can be wanted according to the working performance of different motor products
It asks, the temperature rise threshold values and vibration displacement threshold values of bearing is preset in main control singlechip 1321, once main control singlechip 1321
Monitor that the temperature rise of bearing is greater than threshold values or/and its vibration displacement greater than valve by temperature sensor 21 and vibrating sensor 22
Value carries out automatic oiling with regard to self-starting oiling motor 31 debugged in real time (because existing studies have shown that: there is bearing fault
The reason of at least 80% a possibility that be since bearing lubrication is bad, be because bearing continue high speed rotation, cause lubrication oil/grease
Loss so that bearing temperature rise it is excessively high and because frictional force increase due to generate abnormal vibrations；It is general to be lubricated by replacement or addition
Oil/fluid lubricant can eliminate such failure), thus on the one hand can avoid fault diagnosis fault, it on the other hand can be at first
Between prevent fault progression；If the temperature rise of bearing and vibration displacement are not revert to normally after addition lubricating oil/fluid lubricant
Range (that is: be still higher than threshold values), the failure for showing at this time are not due to insufficient lubrication and cause, therefore, once there is this failure,
Main control singlechip 1321 can send fault alarm information to transmitter 24.When the transmitter 24 is equipped with display screen 241, transmitting day
When line 242 and wireless communication module 243, remote terminal 25 (such as: motor background monitor, maintenance of motor personnel mobile phone or electricity
Brain) fault alarm notice can be received in time, thereby executing the faulty motor by the wireless telecommunications between transmitter 24
Detection and maintenance that starting switching and maintenance personnel with spare motor carry out the faulty motor to scene are closed, so as to
The serious consequences such as the motor damage caused by bearing fault and unexpected shutdown are utmostly reduced, there is significant industrial value.
