All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
In the related art of a grease-lubricated bearing, in the course of using the grease-lubricated bearing, since the grease therein is a semi-solid lubricant made of a base oil, a thickener and an additive, the grease in the grease-lubricated bearing is generally non-uniform when the bearing is completely assembled. Abnormal sound can appear in the process of starting the instrument and equipment and reaching the target high-speed and ultra-high-speed rotation, and the temperature of the bearing can be greatly increased, so that serious faults such as bearing damage, instrument and equipment damage and the like are caused.
Based on the above, the embodiment of the invention provides a bearing fat running method, a device, computer equipment and a storage medium, wherein the fat running information of a target bearing is determined based on a rated rotating speed by acquiring the rated rotating speed of the target bearing, and the fat running information is used for representing the fat running time of the target bearing at a plurality of target fat running rotating speeds; acquiring bearing temperature thresholds corresponding to the target bearing under a plurality of target grease running rotating speeds; performing grease running on the target bearing based on the grease running information, and acquiring the grease running temperature of the target bearing; if the temperature of the grease running is equal to the target temperature rising rate and lasts for the target time before the temperature of the grease running reaches the bearing temperature threshold corresponding to each target grease running rotating speed, the grease running of the target bearing is finished.
In this embodiment, a bearing grease running method is provided, which may be used in an apparatus, and fig. 1 is a flowchart of a bearing grease running method according to an embodiment of the present invention, as shown in fig. 1, where the flowchart includes the following steps:
step S101, obtaining the rated rotation speed of the target bearing.
The rated rotation speed of the target bearing can be determined based on the calibration information of the target bearing, and a necessary condition is provided for determining the grease running rotation speed range of the target bearing by acquiring the rated rotation speed of the target bearing.
For example, when the target bearing is subjected to grease running, the target bearing is firstly installed at a corresponding position of an instrument (such as a molecular pump) so as to drive the target bearing to rotate by using the direct current brushless motor, the molecular pump body and the main shaft, and the grease is run.
Step S102, determining grease running information of the target bearing based on the rated rotating speed, wherein the grease running information is used for representing the grease running time of the target bearing at a plurality of target grease running rotating speeds.
And determining the grease running time of the target bearing at a plurality of target grease running speeds through the rated rotating speeds so as to conveniently run grease to the target bearing based on the corresponding grease running speeds and the grease running time, thereby improving the grease running efficiency of the target bearing.
In some alternative embodiments, the minimum fat running speed, the maximum fat running speed, and the speed adjustment interval of the target bearing may be determined based on the rated speed; determining a plurality of target fat running speeds and corresponding fat running times of the target bearing based on the lowest fat running speed, the highest fat running speed and the speed adjustment interval; and determining the grease running information of the target bearing based on the plurality of target grease running speeds and the corresponding grease running time. The grease running direction of the target bearing at least comprises the working running direction of the target bearing, namely the grease running direction of the target bearing comprises the same direction (such as clockwise direction) as the working running direction and the opposite direction (such as anticlockwise direction) as the working running direction.
Specifically, the minimum running speed of the target bearing may be a first preset percentage, such as 10%, of the rated speed; the maximum fat running speed may be a second preset percentage of the rated speed, for example, 110%, the maximum frequency interval corresponding to the speed adjustment interval may be kept within a preset speed interval, for example, 200Hz, a larger frequency interval may cause instability and noise abnormal noise during the starting process, and at this time, it is suitable to select a frequency interval around 100Hz as the speed adjustment interval to increase the speed. At the same time, running fat at rated rotational speed is also necessary. That is, the rotational speed adjustment is not completely fixed, but is adjusted based on the rotational speed of the desired running fat. Therefore, the plurality of target fat running speeds of the target bearing at least comprise the lowest fat running speed, the rated fat running speed, the highest fat running speed and the fat running speed corresponding to the speed adjusting interval. When the target bearing runs grease at each target grease running rotating speed, the grease running time of the target bearing at each target rotating speed can be determined based on the influences of the target grease running rotating speed and time on the performance and the temperature of the target bearing, and the grease running time can be repeated for the target times by adopting the corresponding grease running time in order to ensure the sufficiency of the grease running.
For example, if the frequency corresponding to the rated rotation speed of the target bearing is 500Hz, determining that the grease running information of the target bearing is that the target bearing is reduced to 0Hz after being accelerated from 0Hz to the lowest grease running rotation speed (50 Hz) for 5min, repeating for 5 times repeatedly, wherein the grease running maintenance time can be 6min, and the repetition times are 12 times; then raising the running speed to 100Hz for 10 min, then reducing the running speed to 0Hz, and repeating the process for 5 times (12 times can be also adopted); then raising the running speed to 200Hz for 10 minutes, then reducing the running speed to 0Hz, and repeating for 5 times; then raising the running speed to 400Hz for 1 minute, then reducing the running speed to 0Hz, and repeating for 5 times; then raising the running speed to 500Hz for 1 minute, then reducing the running speed to 0Hz, and repeating for 5 times; and then raising the running speed to 600Hz for 1 minute, then reducing the speed to 0Hz, and repeating the process for 5 times.
According to the bearing fat running method provided by the embodiment of the invention, the minimum fat running rotating speed, the maximum fat running rotating speed and the rotating speed adjusting interval of the target bearing are determined based on the rated rotating speed, so that a plurality of target fat running rotating speeds and corresponding fat running time of the target bearing are determined, and a necessary condition is provided for reliable fat running of the target bearing.
In some optional embodiments, a resonance point of the target bearing in the fat running process can be obtained, and a rotating speed range corresponding to the resonance point is determined; determining the grease running rotating speed range of the target bearing based on the rated rotating speed and the rotating speed range corresponding to the resonance point; determining the lowest fat running rotating speed and the highest fat running rotating speed of the target bearing and a rotating speed adjusting interval based on the fat running rotating speed range; determining a plurality of target fat running speeds and corresponding fat running times of the target bearing based on the lowest fat running speed, the highest fat running speed and the speed adjustment interval; and determining the grease running information of the target bearing based on the plurality of target grease running speeds and the corresponding grease running time.
The frequency corresponding to the rotating speed range of the resonance point of the target bearing in the fat running process is 400Hz, the frequency corresponding to the rated rotating speed of the target bearing is 500Hz, the fat running information of the target bearing is determined to be that the target bearing is decelerated to 0Hz after the target bearing is accelerated from 0Hz to the lowest fat running rotating speed (50 Hz) for 5min, the speed is repeated for 5 times, the fat running maintenance time can be 6min, and the repetition time is 12 times; then raising the running speed to 100Hz for 10min, then reducing the running speed to 0Hz, and repeating the process for 5 times (12 times can be also adopted); then raising the running speed to 200Hz for 10min, then reducing the running speed to 0Hz, and repeating for 5 times; then raising the running speed to 385Hz, maintaining for 1min, then reducing the speed to 0Hz, and repeating for 5 times; then raising the running speed to 405Hz for 1min, then reducing the running speed to 0Hz, and repeating for 5 times; then raising the running speed to 500Hz for 1min, then reducing the running speed to 0Hz, and repeating for 5 times; and then raising the running speed to 600Hz for 1min, then reducing the running speed to 0Hz, and repeating for 5 times. I.e. fat must be run on both sides of the resonance point.
According to the bearing fat running method provided by the embodiment of the invention, the resonance point of the target bearing in the fat running process is obtained, the rotating speed range corresponding to the resonance point is determined, and the fat running rotating speed range of the target bearing is determined based on the rated rotating speed and the rotating speed range corresponding to the resonance point, so that the condition that the fat running effect is reduced due to resonance when the target bearing runs fat in the rotating speed range corresponding to the resonance point is avoided; the minimum fat running rotating speed, the maximum fat running rotating speed and the rotating speed adjusting interval of the target bearing are determined based on the fat running rotating speed range, so that a plurality of target fat running rotating speeds and corresponding fat running time of the target bearing are determined, and necessary conditions are provided for reliable fat running of the target bearing.
Step S103, obtaining corresponding bearing temperature thresholds of the target bearing at a plurality of target grease running speeds.
The bearing temperature threshold value corresponding to the target bearing under the plurality of target grease running rotating speeds can be determined based on the influence of the grease running time of the target bearing under the corresponding target grease running rotating speeds on the bearing temperature. Through the setting of bearing temperature threshold to when the fat temperature that runs of target bearing reached bearing temperature threshold, stop running fat, and then avoid continuing to run fat and cause the influence to the bearing quality.
And step S104, performing grease running on the target bearing based on the grease running information, and acquiring the grease running temperature of the target bearing.
When the target bearing is subjected to grease running based on the grease running information, the grease running temperature of the target bearing is obtained, and the grease running of the target bearing under the current target grease running rotating speed is ended based on the relation between the grease running temperature of the target bearing and the bearing temperature threshold value.
In some alternative embodiments, when the target bearing is subjected to fat running based on the fat running information, the speed adjustment time between a plurality of target fat running speeds can be obtained; and performing grease running on the target bearing based on the rotating speed adjusting time and the grease running information. Wherein the speed adjustment time is related to the speed of the target running fat speed up rate versus the target bearing running fat temperature and performance.
According to the bearing fat running method provided by the embodiment of the invention, the speed adjustment time among a plurality of target fat running speeds is obtained, and the target bearings are subjected to fat running based on the speed adjustment time and the fat running information, so that the fat running efficiency and the fat running reliability of the target bearings are further improved.
Step S105, if the temperature of the grease running reaches the bearing temperature threshold corresponding to each target grease running rotating speed, the temperature rising rate is equal to the target temperature rising rate and lasts for the target time, and the grease running of the target bearing is ended.
Specifically, obtaining the grease running temperature and the heating rate of the target bearing at each target grease running rotating speed; comparing the fat running temperature with a corresponding bearing temperature threshold to obtain a temperature comparison result; if the temperature comparison result indicates that the running fat temperature is smaller than the corresponding bearing temperature threshold value, acquiring the temperature rising rate corresponding to the running fat temperature and timing; if the temperature rising rate is equal to the target temperature rising rate and the timing reaches the target time, ending the grease running of the target bearing so as to improve the uniformity and the balance of the grease running of the target bearing.
The most important measurable variable for measuring the fat running effect and the bearing state in the fat process is temperature. When running grease at a frequency corresponding to a certain target grease running rotating speed, the temperature of the target bearing needs to be continuously monitored, and the temperature inside the target bearing is generally difficult to measure, so that the condition of the temperature inside the target bearing can be evaluated by measuring the temperature of the outer ring of the target bearing. Generally, the temperature is continuously increased to a certain extent, the temperature tends to be stable, and the stable temperature does not reach the upper temperature limit, which is a precondition for the running process, so that after the running at the stable temperature is performed for a period of time (i.e. the temperature rising rate is equal to the target temperature rising rate and the timing reaches the target time, for example, 5-10 min), the running process at the target running speed can be considered to be completed.
According to the bearing grease running method, the grease information of the target bearing, namely the grease running time under a plurality of target grease running speeds, is determined based on the rated rotating speed of the target bearing, so that the reliability of grease running of the target bearing is improved; the bearing temperature threshold values corresponding to the target bearing under a plurality of target grease running rotating speeds are obtained, so that damage to the bearing caused by overhigh grease running temperature in the grease running process is avoided; the grease running information is used for carrying out grease running on the target bearing, and the grease running temperature of the target bearing is obtained, so that a necessary condition is provided for confirming the grease running explanation time of the target bearing; if the grease running temperature is equal to the target temperature rising rate and lasts for the target time before reaching the bearing temperature threshold corresponding to each target grease running rotating speed, the grease running of the target bearing is finished, and the grease running efficiency and uniformity of the target bearing are improved.
In some optional embodiments, if the temperature of the running fat is equal to the target temperature rising rate and lasts for a target time before reaching the bearing temperature threshold corresponding to each target running fat rotating speed, obtaining a running fat current corresponding to the maximum running fat rotating speed in the plurality of target running fat rotating speeds, and a current threshold; comparing the target running fat current with a current threshold value; if the target grease running current is smaller than the current threshold value, ending the grease running of the target bearing, and outputting the grease running qualified information of the target bearing.
