A pump water lubricated bearing and a water guide groove profile optimization method

Abstract

The invention discloses a water-lubricated bearing for a pump and a water guiding tank molded line optimizing method. The water-lubricated bearing comprises an outer alloy sleeve and a rubber embedded sleeve with a self-lubricating action. The outer alloy sleeve and the rubber embedded sleeve constitutes the outer wall and the inner wall of the water-lubricated bearing correspondingly. The rubber embedded sleeve is composed of tanks and platforms, and intersecting angles of the water guiding tanks and the platform areas all have fillets. The spiral direction of a water guiding tank molded line is the axis rotating direction. According to the water-lubricated bearing, through the connection of the outer alloy sleeve and the rubber embedded sleeve, damping and protecting actions are achieved. The fillets at the bottoms of the water guiding tanks of the rubber embedded sleeve are designed, so that the residue and abrasion of water dregs are effectively avoided. The fillets at the tops of the water guiding tanks of the rubber embedded sleeve are designed, so that decompressing and abrasion reducing actions are achieved. Due to the water-lubricated materials and water guiding tank molded line characteristics of the water-lubricated bearing, at the time of starting, a certain time of dry friction can be allowed, and deformation fracture does not occur.

Description

technical field [0001] The invention belongs to the technical field of water-lubricated bearings, and in particular relates to the practical application of a method for optimizing water-lubricated bearings of pumps. The water-lubricated bearings are mainly used to reduce abrasive wear and improve bearing capacity. Background technique [0002] In recent years, with the development of the pump industry, many water-lubricated bearings that use their own liquid as the lubricating fluid have been widely used. This will become an inevitable industry development trend, and water-lubricated bearings will gradually replace oil-lubricated bearings. The reason why water-lubricated bearings can replace oil-lubricated bearings is widely used in the pump industry, and its advantages are obvious. [0003] Firstly, using water as a lubricant can effectively avoid pollution and protect the environment; secondly, it will greatly save the use of lubricating oil; thirdly, because water has a ...

Problems solved by technology

At present, there are no relevant patent reports on water-lubricated bearings for pumps. How to reduce the dry friction during startup by changing the internal profile of the water-lubricated bearings, thereby improving the wear resistance stability of the bearings, is the key issue for the optimization of water-lubricated bearings.

In addition, the speed of the high-speed pump is too high, resulting in excessive pressure on the bearing and thinning of the liquid film; and how to optimize the internal profile of the water-lubricated bearing to quickly and efficiently transport the liquid dross of the cleaning groove, all of which are water-lubricated Important issues facing bearings
