In order to solve the above-mentioned problems, the present invention provides a near-remote early warning system 100 for motor bearing lubrication oil deficiency, and fig. 1 to 2 are specific embodiments of the near-remote early warning system for motor bearing lubrication oil deficiency provided by the present invention.
Referring to fig. 1, the motor bearing lubrication oil loss near-remote early warning system 100 includes: the vibration sensor 1, the display 6, first counter 4 and controller 2, vibration sensor 1 is used for detecting the vibration signal that produces when motor bearing operates, the output electricity of controller 2 is connected alarm 2, and its input with the output electricity of vibration sensor 1 is connected, controller 2 is used for when receiving vibration signal is high-frequency vibration signal, judges motor bearing lubricating oil and lacks, and controls alarm 2 to start, and after motor bearing supplements lubricating oil, controller 2 control first counter 4 starts to count until the next receipt vibration signal is high-frequency vibration, and record time interval x: if x is less than or equal to the set value a, the controller 2 determines that it is a first fault and displays it on the display 6; if x is greater than a and less than or equal to the set value b, it is determined that it is a second fault and displayed on the display 6.
In the technical scheme provided by the invention, the vibration sensor 1 is arranged to detect the vibration signal generated when the motor bearing runs in real time and transmit the vibration signal to the controller 2, when the lubricating oil is in a shortage, the vibration sensor 1 can detect the high-frequency vibration signal generated by the motor bearing due to the lack of the lubricating oil, the motor bearing is judged to be in a lubricating oil shortage state at the moment, the display 6 is controlled to give an alarm response, after the motor bearing is supplemented with the lubricating oil, the controller 2 controls the first counter 5 to start recording the time interval x for receiving the high-frequency vibration signal transmitted by the vibration sensor 1 next time, two set values are set to be a and b respectively, a is smaller than b, when x is smaller than or equal to the set value a, the controller 2 controls the display 6 to display as a first fault, the lubricating oil path is possibly in a non-smooth state, or the lubricating oil selection is in a problem, and a worker can select the directions to conduct positioning checking preferentially; when x is greater than the set value a and less than or equal to the set value b, the controller 2 controls the display 6 to display a second fault, which indicates that the quality of the lubricating oil is seriously deteriorated after long-time use, and timely replacement operation of the lubricating oil is required; when x is greater than the set value b, it means that the lubricant is lost due to normal use only.
In the fault locating process, the display 6 arranged on the controller 2 can play a role in warning and marking, reminding workers that motor bearing lubricating oil is lost, and when receiving signals transmitted by the vibration sensor 1, the controller analyzes the time interval x recorded by the first counter 4, can quickly locate faults, locate fault reasons in real time through the display 6, can primarily judge and locate the fault reasons according to actual conditions, greatly shortens the time for fault locating and checking of subsequent workers, and improves maintenance efficiency.
When the lubricating oil at the motor bearing is subjected to vibration detection, the vibration acceleration peak value and the vibration acceleration frequency spectrum can well reflect the lubrication condition of the bearing, when the bearing is poor in lubrication, the vibration acceleration peak value is higher, obvious weed pile phenomenon can occur at a part above 2kHz in the vibration acceleration frequency spectrum, and along with the deterioration of lubrication, the vibration acceleration peak value and the weed pile amplitude can be obviously increased. When the lubricating oil is in a state of missing, the bearing is not well lubricated, and obvious weed pile phenomenon can appear at the part above 2kHz in the vibration acceleration frequency spectrum, but after the lubricating oil is timely filled, the weed pile phenomenon can be quickly improved and the lubricating state is restored; when the phenomenon of oil way blockage and the like occurs, the filled lubricating oil is not easy to enter the motor bearing, so that the simple lubricating oil filling cannot achieve a good effect, and after the lubricating oil is filled, the weed pile phenomenon cannot be improved, so that when the interval time x is smaller than the set value a, the phenomenon that the lubricating oil is not filled in the motor bearing at the moment is a fault such as unsmooth oil way and the like; in contrast, when the quality of the lubricating oil is deteriorated, the lubrication condition is temporarily improved after the lubricating oil is filled, and at this time, the acceleration peak value is temporarily reduced to the normal level, but after a short period of time, the lubrication failure occurs rapidly, so that when the interval time x is greater than a and less than the set value b, the lubrication failure is caused by the quality deterioration in the lubricating oil.
In order to ensure that the motor bearing can ensure the lubrication state at any time, after each interval of time, lubricating oil needs to be actively added to the motor bearing, because the time of use of the motor varies, a worker can only know the time elapsed after the adding of the lubricating oil, but the time used after the adding of the lubricating oil is difficult to intuitively understand, and in order to prevent the motor bearing lubricating oil from being lost in the normal use state, in the embodiment of the invention, the motor bearing lubricating oil loss near-remote early warning system 100 further comprises a second counter 3 and a lubricating oil adding device 7 which are electrically connected with the controller 2, after the motor is replenished with the lubricating oil, the controller 2 controls the second counter 3 to start timing, and records the elapsed time as y: if y is equal to the set value m, the set value m indicates that the set use time of the lubricating oil in the motor bearing is needed to be filled, the lubricating oil is displayed on the display, and after the lubricating oil adding device 7 adds the lubricating oil to the motor bearing, the controller 2 controls the second counter 3 to clear the measured time y, and the measured time y is displayed on the display and is re-timed. After the motor bearing is replenished with lubricating oil, the second technical controller 8 records the time y elapsed after the motor bearing is replenished with lubricating oil, when y is equal to a set value m, the time y indicates that the lubricating oil in the motor bearing reaches a set use duration, the display 6 displays the information that the lubricating oil reaches the set use duration, at the moment, the replenishing operation of the lubricating oil needs to be carried out on the motor bearing, and after the replenishing operation, the display 6 displays the information that the lubricating oil is replenished, the second counter 3 clears y, and repeats the operation, thereby realizing the monitoring of the use duration of the lubricating oil on the motor bearing, being convenient for staff to intuitively monitor whether the use duration of the lubricating oil of the motor bearing reaches the designated duration, and preventing the lubricating oil of the motor bearing from being lost in a normal use state.
After the lubrication of the motor bearing is used for a long time, the metal scraps in the lubrication oil are too much, and at the moment, the lubrication oil needs to be replaced integrally so as to ensure good lubrication effect, because the service time of the motor is changed, a worker can only know the time of the whole lubrication oil replacement, and the total time length of the lubrication oil use of the motor bearing is difficult to intuitively understand, in the embodiment of the invention, the output end of the controller 2 is electrically connected with a third counter 5, and after the motor bearing is disassembled and cleaned and the lubrication oil is refilled, the controller 2 controls the third counter 5 to measure the total time length z of the motor bearing which is reinstalled and filled with the lubrication oil: when the time z is equal to the set value n, the controller 2 controls the display 6 to display that the total time length of the lubricating oil reaches the set time length of the lubricating oil, and after the motor bearing is disassembled and cleaned and the lubricating oil is refilled, the controller 200 controls the third counter 5 to measure the total time length z to be zero, and the total time length z is displayed on the display 6 and is re-counted. After the motor bearing is disassembled, cleaned and then the lubricating oil is added, the controller 7 records the total time length z which passes after the lubricating oil is refilled, when the total time length z is equal to the set value n, the total time length display lamp 71 is turned on to warn, the staff is reminded of disassembling and cleaning the motor bearing and refilling the lubricating oil, after the lubricating oil is refilled, the total time length display lamp 71 is turned off to indicate that the lubricating oil is refilled, the third counter 5 clears z again, the operation is repeated, the monitoring of the total time length of the lubricating oil at the motor bearing is realized, the staff can intuitively know whether the total time length of the lubricating oil at the motor bearing reaches the designated time length, and the maintenance is convenient.
When the situation that lubricating oil is absent at the motor bearing is needed to be added to the motor bearing timely, if the lubricating oil is added by a worker, the situation that the lubricating oil is not added timely can occur, in the embodiment of the invention, referring to fig. 2, the lubricating oil adding device 7 comprises an oil storage tank 71 with an oil inlet vertically arranged at the top, an oil outlet pipe 74 is communicated with the bottom end of the oil storage tank 71, the bottom end of the oil outlet pipe 74 is communicated with an oil inlet hole of the motor bearing, a control valve 73 for controlling the on-off of the oil outlet pipe 74 is arranged on the oil inlet hole, and the control valve 73 is electrically connected with the controller 2. The lubricating oil adding device 7 is used for adding lubricating oil, after the controller 2 opens the control valve 73, the lubricating oil in the oil storage tank 71 flows to the oil inlet hole of the motor bearing through the oil outlet pipe 74, and the controller 2 is used for controlling the control valve 73 to be opened and closed, so that the automatic adding of the lubricating oil at the motor bearing is realized, and the timeliness of the adding of the lubricating oil is ensured.
The lubricating oil in the oil storage tank 71 is fed through the oil inlet, the flow of the lubricating oil is realized mainly by the gravity of the lubricating oil, the flow speed is slow, and the lubricating oil adding efficiency is reduced. The corresponding sealing block 72 is pushed by the driving mechanism to move up and down, at this time, the lubricating oil in the inner cavity of the oil storage tank 71 can be more rapidly discharged from the oil outlet pipe 74 under the action of gravity of the lubricating oil and the action of the force applied by the sealing block 72, so that the discharge speed of the lubricating oil in the oil storage tank 71 is increased, and the adding efficiency of the lubricating oil is improved.
In the technical scheme provided by the invention, the driving mechanism is an electric push rod 76 which is fixedly arranged at the top end of the oil storage tank 71 and can vertically stretch, and the stretching end of the electric push rod 76 penetrates through the oil storage tank 71 and extends to the inner cavity of the oil storage tank 71 to be fixedly connected with the sealing block 72.
When the oil inlet of the oil storage tank 71 is filled with the lubricating oil, the lubricating oil moves to the position above the sealing block 72, then enters the position below the sealing block 72 through the one-way valve 75, and the oil inlet speed is low.
In order to enable the lubricant in the oil storage tank 71 to be discharged through the oil outlet pipe 74 in a large amount, so as to avoid excessive lubricant remaining at the bottom end of the inner cavity of the oil storage tank, in the embodiment of the invention, the bottom end of the inner cavity of the oil storage tank 71 is in a slope structure, and the slope structure is disposed near the oil outlet pipe 74 and is inclined downward. By means of the inclined surface structure, the lubricating oil can be converged to the upper position of the oil outlet pipe 74 and discharged under the action of gravity of the lubricating oil, and excessive lubricating oil residues in the inner cavity of the oil storage tank 71 can be effectively avoided.
The oil outlet pipe 74 is directly opened through the control valve 73 to fill the lubricating oil, but the amount of the lubricating oil to be filled is not well and intuitively known, and the condition of too much or too little lubricating oil to be filled easily occurs. After detecting the signal, the sensor transmits the signal to the controller 2, and the controller 2 analyzes the transmitted signal to realize the detection of the lubricating oil residual quantity.
The specific implementation of the sensor is not limited, and the oil remaining in the oil tank 71 may be reacted by measuring the hydraulic pressure, the oil remaining in the oil tank 71 may be reacted by measuring the change in the liquid level, or the like, and the present invention is not limited thereto.
Specifically, in the technical scheme of the invention, the sensor is a ranging sensor for measuring the moving distance of the sealing block, the ranging sensor is positioned above the sealing block, and the ranging sensor is specifically a laser ranging sensor. When the oil storage tank 71 is used for adding lubricating oil to the motor bearing, the sealing block 72 and the inner side wall of the oil storage tank 71 form a closed space, so that the lubricating oil in the inner cavity of the oil storage tank 71 is not easy to flow out under the action of atmospheric pressure, when the sealing block 72 is pushed downwards, the lubricating oil moves downwards under the action of the force exerted by the sealing block 72, the filling amount of the lubricating oil is in direct proportion to the moving displacement amount of the sealing block 72, and after the adding of the lubricating oil is finished, the distance measuring sensor measures the change of the displacement distance of the sealing block 72, so that the quantity of the added lubricating oil can be known, and the measuring of the lubricating oil filling amount is facilitated.
