Background

In order to allow the mechanical equipment to operate normally, it is necessary to supply a proper amount of lubricating oil to mechanical equipment parts such as rotating equipment.

The lubrication points which are traditionally used in industry and need maintenance for mechanical equipment are manually filled with oil by using an oil filler or an electric and pneumatic oiling machine, lubrication maintenance and routine maintenance inspection are performed on individual single points, for example, the lubrication of bearings of rotating equipment, because the lubrication points which need maintenance may be more than one, the individual operating conditions and requirements have obvious differences, except that the oil filling time cannot be really controlled and executed, the oil supply amount cannot be controlled to meet the lubricating oil amount required by the bearings, and the time when the oil needs to be replenished again (the requirement of the bearings for lubricating oil cannot be determined by regular oil filling) cannot be estimated, and the maintenance is performed as soon as possible by past experience of maintainers, so the following problems are common:

1. insufficient oiling: causing the bearing to wear rapidly and the deterioration degree cannot be controlled, forming an unplanned shutdown (sudden failure), if the bearing is not installed properly, the lubricating oil cannot enter the loop, causing the bearing to burn out.

2. Refueling excess: the bearing ball is in rolling friction, excessive oiling forms an oil film which is too thick to cause sliding friction of the bearing ball, the bearing ball is in single-point sliding contact with a loop to cause high-temperature burning, or the motor bearing is excessively oiled to cause coil short circuit.

SUMMERY OF THE UTILITY MODEL

Whether excessive oil injection, insufficient oil injection or overtime supplement is adopted, the situations are usually important factors causing bearing damage or shortening of service life, not only resources and manpower are consumed, but also shutdown is caused to influence production, and therefore how to solve the existing problems is always the direction of research of the inventor.

Detailed Description

The technical solution in the embodiments of the present invention is clearly and completely described below with reference to the drawings in the embodiments of the present invention. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention, but the present invention may be practiced in other ways than those specifically described and will be readily apparent to those of ordinary skill in the art without departing from the spirit of the present invention, and therefore the present invention is not limited to the specific embodiments disclosed below.

Referring to fig. 1 and 2, which are views illustrating an embodiment of the lubrication management fault alarm system according to the present invention, the lubrication management fault alarm system 1 is connected to a rotating device 2 for detecting whether a bearing in the rotating device 2 is abnormal, and the lubrication management fault alarm system 1 includes at least one sensor 11, a plurality of oil injectors 12, and a signal collection box 13.

The sensor 11 is installed at a suitable bearing position of the rotating device 2 for sensing the vibration wave and vibration data monitoring during the bearing action of the rotating device 2.

The plurality of oil injectors 12 are provided to be installed at appropriate bearing positions of the rotating equipment 2, respectively, to supply lubricating oil for supplementing the bearings of the rotating equipment 2.

The signal collection box 13 is connected to the sensors 11 and the oil injectors 12 for collecting signals and data detected by the sensors 11 and instructing the oil injectors 12 to supply oil. The signal collection box 13 is provided with a judgment module 131 and a warning module 132, wherein the judgment module 131 is used for judging and filtering the signals and data detected by the sensor 11, and providing the warning module 132 with warning signals corresponding to the signals and data and indicating the oil injectors 12 to supply oil.

In addition, the user can also install a computer server 14 at the remote end (such as office or monitoring room) to connect with the signal collection box 13, so as to synchronously display the message and warning signal of the signal collection box 13, and the staff can synchronously receive the latest information from the remote end.

Therefore, when the device is implemented, a user can install one or more sensors 11 and the oil injector 12 at a proper bearing position of the rotating equipment 2 in advance, so that after the sensors 11 are started, the vibration wave and vibration data monitoring during the bearing action of the rotating equipment 2 can be sensed at any time, the data are transmitted back to the signal collection box 13, after the signal collection box 13 receives the data, the signals and the data detected by the sensors 11 can be judged and filtered at any time, and warning signals corresponding to the signals and the data are provided, for example, a green light is used for displaying when the stability is normal, a yellow light is used for warning when the abnormality is normal, and a red light is used for warning when the numerical value is over-limit.

When abnormal signals such as a yellow light occur, the signal collection box 13 also synchronously instructs the oil injector 12 to supply oil so as to lubricate the bearing of the rotating equipment 2, the oil injection is stopped until the warning light returns to a green light from the yellow light, and when a user synchronously watches the change of the warning signal in front of the signal collection box 13 or the computer servo 14, whether the fault is eliminated or the oil injection is invalid and the machine needs to be stopped immediately is judged.

Therefore, the design of the utility model has the following advantages:

1. because one of the factors of the failure of the bearing of the rotating equipment is the lubrication problem, the function of controlling the oil injector is added, when the data reaches the alarm, the oil injector is oiled, when the data is recovered to be normal after the oil injector is oiled, namely the alarm is relieved, and the data monitoring is continued, if the data still reaches the alarm, the abnormality is listed and the owner is informed to carry out the equipment maintenance, so the design of the utility model can predict the equipment condition, and the equipment maintenance can be carried out early.

2. The utility model belongs to predictive maintenance (optimized optimization maintenance mode), and effectively predicts failure time and reacts in advance to avoid abnormity in development, so that sudden shutdown or failure is reduced by 70-75%. Meanwhile, by the design of the utility model, the equipment downtime can be effectively predicted, an optimal maintenance plan is formulated, and abnormal equipment can be arranged to be maintained in advance during maintenance, so that the overall operation efficiency is effectively improved.

3. By the design of the utility model, timely and proper oiling is provided, the condition that the oil loss is instantly oiled when the oil loss is detected is monitored, the abnormal improvement opportunity is mastered, the bearing oil loss abrasion is avoided, or the condition that a heating bearing is burnt due to the slipping of an excessively oiled ball is caused, so that the running of the bearing is close to the design life (the running Time is optimized), the using amount of lubricating oil is effectively managed, the secondary damage of other parts caused by the abnormal parts (such as the abrasion of an axle center and the bearing caused by poor centering) is reduced, the part inventory and the labor cost are greatly reduced, the material driving cost is eliminated, and the average service life MTBF (mean Time Between failures) of equipment is maximized.
