Description

Technical Field

[0001] The utility model relates to the technical field of lubrication equipment, and more specifically, to a lubrication spraying device. Background Art

[0002] Lubricants are added between two contacting surfaces in relative motion to form a lubricating film between the two friction surfaces, separating the surfaces in direct contact and turning dry friction into internal friction between lubricant molecules, thereby reducing friction, reducing wear, and extending the service life of mechanical equipment. Mechanical equipment used in the production process usually needs to be maintained with lubricating oil, usually by dripping or spraying with a nozzle to lubricate the areas that need lubrication.

[0003] For example, the authorization announcement number CN206723790U discloses an adjustable lubricating oil nozzle, which filters the lubricating oil by setting a filter chamber to prevent fine impurities in the lubricating oil from clogging the nozzle. The oil intake and air intake can be controlled by adjusting the valve and the oil inlet valve, so as to adjust the spraying form of the lubricating oil and the high-pressure gas after mixing. When the mechanical connection area to be lubricated is small, that is, when point lubrication is performed, the regulating valve can be closed and the oil inlet valve can be lowered so that the lubricating oil drips out in the form of oil droplets at the nozzle; when the mechanical connection area to be lubricated is large, the regulating valve and the oil inlet valve are opened at the same time, so that the lubricating oil is mixed with the high-pressure gas and sprayed out in the form of mist at the nozzle; the size of the regulating valve and the oil inlet valve can be relatively adjusted to meet the requirements of different mechanical connection areas and lubrication amounts; spiral blades are provided in the oil inlet pipe, which can cause the lubricating oil to generate vortexes when entering the mixing chamber, thereby improving the mixing efficiency between the lubricating oil and the high-pressure gas.

[0004] In the above scheme, only the amount of lubricating oil sprayed and the spraying area of ​​the lubricating oil can be adjusted, but the position of the nozzle remains unchanged during use, resulting in the nozzle being able to adjust only the mechanical surface passing through the nozzle, and unable to adjust the position according to the specific conditions of the mechanical equipment, and having low specificity.
