According to different load and different design speeds, can be by adjusting internal layer oil film and outer layer oil film
Length and inside and outside oil film thickness plain bearing unit is optimized, it is ensured that high-speed main spindle rotor bearing system
System efficient stable runs.Thus ensure that centrifugal pump is efficient, safe and stable operation.
In the running up of centrifugal pump, floating sliding bearing runs with certain speed, usual sliding axle
The rotating speed held is 0.1-0.3 times of high-speed main spindle rotating speed).Due to the rotation of sliding bearing, reduce height
Relative velocity between speed main shaft and sliding bearing.Theoretical according to friction energy loss, friction power loss and relative speed
Square being directly proportional of degree.By 0.2 times of calculating that sliding bearing average speed is high-speed main spindle speed, typically
For, sliding bearing fixing with employing is compared, and uses and optimizes, i.e. according to different loads and running speed,
Reasonably select the height of the floating sliding bearing of the width of oil film inside and outside sliding bearing and the thickness of inside and outside oil film
Speed centrifugal pump friction power loss decreases beyond 30%.
The centrifugal pump high-speed main spindle of the present invention uses floating sliding bearing to support.Due to high-speed main spindle and slip
Between bearing, friction power loss reduces, and the heat produced between high-speed main spindle and sliding bearing reduces, thus
Reduce the temperature of lubricating oil between high-speed main spindle and sliding bearing.Thus reduce high-speed main spindle and slip
The risk of lubricating oil carbonization between bearing, it is ensured that the safe and reliable operation of high-speed centrifugal pump.
The vibration that high-speed main spindle and high gear etc. produce is by the oil film between high-speed main spindle and sliding bearing
It is delivered on sliding bearing, is delivered to bearing block by the oil film between sliding bearing and bearing block the most again
On.Outer oil film and interior oil film are all equivalent to a damper.Therefore with monolayer oil film sliding bearing phase
Ratio, how the floating sliding bearing with two-layer oil film has been equivalent to a damper, has therefore been delivered to
Vibration on bearing block reduces.
The high-speed main spindle of the centrifugal pump of the present invention uses the floating sliding bearing of double-layer oil film to support.Due to height
Between speed main shaft and sliding bearing, the reduction of friction power loss, improves the mechanical efficiency of centrifugal pump；Due to height
The heat produced between speed main shaft and sliding bearing reduces, thus reduce high-speed main spindle and sliding bearing it
Between temperature.Thus reduce the risk of lubricating oil carbonization between high-speed main spindle and sliding bearing, improve
The reliability of high-speed centrifugal pump；The two-layer film damper that passes through of mechanical vibration reduces, and reduces
The vibration of high-speed centrifugal pump and noise level.
Above-described detailed description of the invention, is carried out the purpose of the present invention, technical scheme and beneficial effect
Further describe, be it should be understood that the foregoing is only the present invention detailed description of the invention and
, the protection domain being not intended to limit the present invention, all within the spirit and principles in the present invention, done
