Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical lubrication, and particularly relates to an oil mist generator. Background Art

[0002] Oil mist lubrication is to first split the lubricating oil into fine lubricating oil mist through a nozzle or other mechanism, and then spray it on the surface of the machine parts that need lubrication. These small lubricating oil mists can reduce the wear caused by friction and increase the life of the machine.

[0003] However, in the existing technology, the oil pump of the oil mist generator will stop and slip, and will not produce oil when idling, and will not automatically alarm. Problems can only be discovered through manual inspections. The lack of oil mist will cause damage to machine parts such as the hot roller bearings of the spinning equipment, resulting in line stoppages and affecting production efficiency.

[0004] For example, document CN213037895U discloses a device for monitoring the amount of oil pump, such as Figure 1 As shown, it can only be judged by visual inspection whether the oil is supplied and by personnel inspection whether it is normal. This detection method is time-consuming and labor-intensive, and cannot fully guarantee normal oil supply. If the oil supply is interrupted for a long time, the hot roller bearings will not be lubricated, causing a large number of bearings to be damaged and the line to be stopped for maintenance, resulting in huge economic losses.

[0005] Therefore, it is necessary to develop an oil mist generator that can promptly detect that the oil pump is idling and cannot produce oil. Utility Model Content

[0006] The purpose of the utility model is to solve the problems existing in the prior art and provide an oil mist generator.

[0007] In order to achieve the above-mentioned purpose, the technical solution adopted by the present utility model is as follows:

[0008] An oil mist generator includes an oil pump and an atomizing head, as well as a liquid flow meter and a photoelectric sensor. The bottom and top of the liquid flow meter are respectively provided with an inlet and an outlet. The outlet of the oil pump is connected to the inlet of the liquid flow meter through a first pipe, and the outlet of the liquid flow meter is connected to the inlet of the atomizing head through a second pipe. A float is provided inside the liquid flow meter, which rises and falls with the liquid level. When the float falls to the lowest position, it blocks the light beam emitted by the photoelectric sensor.

[0009] The principle of the utility model is as follows: when the oil pump provides lubricating oil, the float will float up and the light beam will pass through the liquid flow meter. At this time, the loop of the photoelectric sensor is in the "closed" state, and the photoelectric sensor has no alarm; when the oil pump stops providing lubricating oil, the light beam emitted by the photoelectric sensor is blocked by the float that has dropped to the lowest position. At this time, the loop of the photoelectric sensor is in the "disconnected" state, and the photoelectric sensor changes to the abnormal state of "alarm", which promptly reminds the staff to check and repair, thereby reducing the wear of machine parts, extending the life of the machine, and improving work efficiency.

[0010] As the preferred technical solution:

[0011] In the oil mist generator as described above, the float is a steel ball. The use of a steel ball with a higher density is mainly to ensure that there is a certain pressure at the outlet of the oil pump and the outlet of the atomizing head. The steel ball floats up and leaves the light beam, indicating that the oil pump is supplying oil to the atomizing head normally. If there is no pressure at the outlet of the oil pump, the steel ball drops to the lowest position due to its own weight, and the light beam of the photoelectric sensor is blocked by the steel ball, which will cause an alarm.

[0012] In the oil mist generator described above, the liquid flow meter is in a vertical state, ensuring that when the oil pump is idling, the float drops to the lowest position smoothly and promptly by its own weight, and the photoelectric sensor issues an alarm in time; the light beam emitted by the photoelectric sensor is in a horizontal state, which facilitates the installation and fixation of the photoelectric sensor.

[0013] Beneficial effects:

[0014] (1) When the oil pump provides lubricating oil, the photoelectric sensor does not give an alarm and the oil mist generator operates normally. When the oil pump stops providing lubricating oil, the photoelectric sensor changes to an abnormal state of "alarm", which promptly reminds the staff to check and repair, thereby reducing the wear of machine parts, and is conducive to extending the life of the machine and improving work efficiency.

[0015] (2) The oil mist generator of the present invention has a simple structure and low cost, and is suitable for application in industrial fields such as spinning. BRIEF DESCRIPTION OF THE DRAWINGS

The horizontal light beam 8 emitted by the photoelectric sensor 7 is just completely lowered to the lowest position of the float 6. Full shielding; when the lubricating oil pressure provided by the oil pump 1 is insufficient, the float 6 drops to the lowest position, and the float 6 completely blocks the horizontal light beam 8 emitted by the photoelectric sensor 7. At this time, the loop of the photoelectric sensor 7 is in the "disconnected" state, and the photoelectric sensor 7 changes to the abnormal state of "alarm", which promptly reminds the staff to check and repair, reduce the wear of machine parts, extend the life of the machine, and improve work efficiency; when the lubricating oil pressure provided by the oil pump 1 is sufficient, the float 6 will rise and leave its lowest position, and the horizontal light beam 8 will pass through the liquid flow meter 5. At this time, the loop of the photoelectric sensor 7 is in the "closed" state, the photoelectric sensor 7 has no alarm, and the oil mist generator is in normal working condition.
