Low speed main shaft 2 supports by clutch shaft bearing 3, under the driving of exterior motor 9, rotates; Low speed gear 4 is connected with low speed main shaft 2, rotates by the driving of low speed main shaft 2; High gear 5 and low speed gear 4 phase teeth and, rotate by the driving of low speed gear 4; High-speed main spindle 6 is connected with high gear 5, rotates by the driving of high gear 5.
Centrifugal pump of the present invention is high speed centrifugal pump, refers to adopt the exterior motor of standard, by speed-changing gear box (comprising low speed gear 4 and high gear 5) improve rotating speed, rotating speed 3000 turn per minute more than, maximum speed can reach 30000 and turn per minute.Centrifugal pump of the present invention can be selected corresponding material, as stainless steel, Cuprum alloy etc.The material of sliding bearing can be Cuprum alloy.
Shown in Fig. 1-Fig. 3, sliding bearing comprises bearing body 10, oil groove 11, bearing outer ring 12, oilhole 13 and bearing inner race 14.Oil groove 11 goes in ring and is arranged at bearing body 10 outsides, the accommodating outside lubricant oil of supplying with; Bearing outer ring 12 is positioned at bearing body 10 outsides of oil groove 11 both sides, establishes with outer carrier cunning, when sliding bearing and bearing support relatively rotate, forms outer oil film by the lubricant oil that oil groove is supplied with between bearing outer ring 12 and bearing support; Oilhole 13 is penetrating to be arranged in oil groove 11; Bearing inner race 14 is positioned at bearing body 10 inner sides, establishes with outside high-speed main spindle cunning, when high-speed main spindle and sliding bearing relatively rotate, forms internal layer oil film by the lubricant oil that oil groove 11 is supplied with through oil-through hole 13 between bearing inner race 14 and high-speed main spindle.

Concrete, more as shown in Figure 4, centrifugal pump also comprises oil pump 7, is connected with sliding bearing 1 by oil circuit 8, by pressure to oil groove supplying lubricating oil.Centrifugal pump of the present invention drives by exterior motor 9 the low speed main shaft 2 being supported on clutch shaft bearing 3.Low speed main shaft 2 drives high gear 5 high speed rotating by the low speed gear 4 of speed-changing gear box.High gear 5 drives the high-speed main spindle 6 being supported on sliding bearing 1, high-speed main spindle 6 impeller 90 High Rotation Speeds, thus pumped medium is to the lift of specifying.In order to ensure the good lubrication of floating sliding bearing 1, oil pump 7 carries out pressure pressure lubrication to floating sliding bearing 1 respectively by oil circuit 8.
The support of the high-speed main spindle of centrifugal pump of the present invention adopts sliding bearing, and sliding bearing has the double-layer oil film of internal layer oil film and outer oil film, can between bearing support and high-speed main spindle, freely rotate.
One deck oil film of sliding bearing is outer oil film between bearing support and bearing outer ring, and another layer of oil film is internal layer oil film between high-speed main spindle and bearing inner race.In the time of high-speed main spindle High Rotation Speed, interior oil film frictional force provides power, drive sliding bearing to rotate, and the frictional force of outer oil film is resistance, hinders sliding bearing and rotates.In the time that the frictional force of interior oil film is greater than the frictional force of outer oil film, sliding bearing accelerates rotation.In the time that the frictional force of interior oil film action on sliding bearing equals outer oil film action to surface friction drag on sliding bearing, reach state of equilibrium, sliding bearing at the uniform velocity rotates.The major parameter of sliding bearing has the slenderness ratio (ratio of bearing width and bearing radius) of bearing, outer oil film effective length, and interior oil film effective length, has effective film thickness and interior oil film effective thickness outward.
Outer oil film effective length refers to the Effective face width coordinating between bearing outer ring and bearing support, is numerically equal to bearing outer ring width and deducts the width of oil groove.Interior oil film effective length refers to the Effective face width coordinating between bearing inner race and high-speed main spindle, is numerically equal to bearing inner race width and deducts the width of two ends groove.

According to different load and different design speeds, can be optimized plain bearing unit by length and the inside and outside oil slick thickness of adjusting internal layer oil film and outer oil film, guarantee the operation of high-speed main spindle rotor-bearing system efficient stable.Thereby ensure that centrifugal pump is efficient, safe and stable operation.
In the running up of centrifugal pump, floating sliding bearing is with certain speed operation, conventionally the rotating speed of sliding bearing be high-speed main spindle rotating speed 0.1-0.3 doubly).Due to the rotation of sliding bearing, reduce the relative velocity between high-speed main spindle and sliding bearing.According to friction energy loss theory, square being directly proportional of friction power loss and relative velocity.Be 0.2 times of calculating of high-speed main spindle speed by sliding bearing mean velocity, in general, compare with the fixing sliding bearing of employing, adopt and optimize, according to different loads and running speed, reasonably select the high speed centrifugal pump friction power loss reduction of the floating sliding bearing of the inside and outside width of oil film of sliding bearing and the thickness of inside and outside oil film to exceed 30%.
Centrifugal pump high-speed main spindle of the present invention adopts floating sliding bearing to support.Because friction power loss between high-speed main spindle and sliding bearing reduces, the heat producing between high-speed main spindle and sliding bearing reduces, thereby has reduced the temperature of lubricant oil between high-speed main spindle and sliding bearing.Thereby reduced the risk of lubricant oil charing between high-speed main spindle and sliding bearing, ensure the safe and reliable operation of high speed centrifugal pump.
The vibration of the generation such as high-speed main spindle and high gear is delivered on sliding bearing by the oil film between high-speed main spindle and sliding bearing, and then is delivered on bearing support by the oil film between sliding bearing and bearing support.Outer oil film and interior oil film are all equivalent to a damper.Therefore compare with individual layer oil film sliding bearing, how the floating sliding bearing with two-layer oil film has been equivalent to a damper, and the vibration being therefore delivered on bearing support has reduced.
