Water-lubricated overload protection lubricating oil line supply system and water-lubricated overload protection method

Abstract

The invention belongs to the technical field of water lubrication, and particularly relates to a water-lubricated overload protection lubricating oil line supply system and a water-lubricated overloadprotection method. The overload protection method is characterized in that when a friction coefficient of a water-lubricated friction pair exceeds the critical value, lubricating oil enters the water-lubricated friction pair in the form of an oil line in water through the lubricating oil line supply system to carry out lubricating oil auxiliary lubrication, a generated oil film replaces a fragilewater film to carry out bearing, and water-lubricated overload protection is achieved. The auxiliary lubricating effect of the lubricating oil line each time reaches 2 hours; the effect taking speedis high, and the antifriction amplitude is large; the problem that a water-lubricated material is poor in lubrication under the sudden load change working condition is solved, auxiliary lubrication isconducted for the sudden overload working condition, it is guaranteed that the water-lubricated friction pair material keeps a good lubrication state under the sudden working condition, material abrasion is reduced, the service life is prolonged, and the operation stability is greatly improved; and the system and the method have quick response, a simple structure, ingenious design concept, low manufacturing cost, environment-friendly application and wide market prospect.

Description

Technical field: [0001] The invention belongs to the technical field of water lubrication, and specifically relates to a water lubrication overload protection lubricating oil line supply system and an overload protection method. When the water lubrication friction pair is overloaded, the temporarily provided lubricating oil line enters the water lubrication friction pair to improve the water lubrication. Bearing capacity of lubrication, reduce friction, reduce wear and protect friction pair materials. Background technique: [0002] Lubricating oil has high viscosity and high load-carrying capacity, and has been widely used in the lubrication of various equipment. However, with the gradual enhancement of human awareness of environmental protection and the improvement of environmental legislation, environmental pollution caused by lubricants and non-renewable energy have caused people to turn more attention to environmentally friendly lubricants, and water, as a typical enviro...

Problems solved by technology

However, water has disadvantages such as low viscosity and poor film-forming ability, and there are always problems in practical applications.

Water lubrication has poor anti-interference ability. When the external working conditions change, such as a sudden increase in load, it is easy to cause lubrication failure. However, the application of water-lubricated bearings is often under complex working conditions, such as the abnormal Short-term load impacts such as uniform load, shafting vibration, and water / ocean currents can easily cause the water film in the contact area to collapse and lose its carrying capacity, resulting in increased bearing wear and even failure

[0003] People have studied the bearing structure and materials, designed rectangular, arc-shaped, triangular, and spiral surface grooves, and developed various series of products such as nitrile rubber, Sailong, Feilong, and Angao to improve wear resistance. properties, but none of them change the inherent defects of water as a lubricant

The water film has low bearing capacity and poor anti-interference performance. When the load fluctuates, the lubrication state tends to change from elastohydrodynamic lubrication to boundary lubrication or even dry friction. When the load fluctuation disappears, the water film may not be able to rebuild and return to the normal lubrication state , and then lead to problems such as vibration, noise, wear and tear failure

Once it becomes a dry friction state, it is often necessary to solve the problem of poor lubrication within tens of seconds, otherwise it will lead to burning tiles
