Hereinafter, with reference to the accompanying drawings of embodiments of the present invention.Embodiments described below is to be applied to the present invention As the example of the horizontal shaft type liquid pump of an example of rotating machinery, but the present invention is not limited to the embodiment, also can Enough it is applied to other rotating machineries that fan, compressor, turbine etc. are used to transfer the fluids such as gas or liquid.
In Fig. 1 into Fig. 3, multistage pump 100 is supported and is fixed on mutually opposing a pair of support blocks 21,23.These Support block 21,23 is welded or is fixed on by secure components such as bolts on pallet (or ground) 26.Driving machine 10 is fixed on On support block 28, the support block 28 is fixed on pallet (or ground) 27.In the present embodiment, multistage pump 100 Pallet 26 and the pallet of driving machine 10 27 are separated from each other, but the present invention is not limited to the embodiment.For example, pallet 26 and frame Platform 27 can also be Construction integration thing.That is, the support block 21,23 of supporting multistage pump 100 and the supporting station of supporting driving machine 10 Seat 28 can also be fixed on common pallet.The rotary shaft 1 of multistage pump 100 and the drive shaft 11 of driving machine 10 are via shaft coupling 12 link.The construction of multistage pump 100 is identical with the construction shown in Figure 16, therefore, and it is attached to mark identical to identical inscape The explanation that it is repeated is remembered and omitted to icon.
Support block 21,23 is made up of iron or concrete.Support block 21,23 has symmetrical shape.Support block 21, The length L of 23 axial direction (i.e. the bearing of trend of rotary shaft 1) along multistage pump 100 be between suction inlet 3 and outlet 4 between Every the above.As shown in Fig. 2 the width W of support block 21,23 is more than 1/10th of length L.In addition, width W is each supporting The mean breadth of pedestal.As shown in figure 3, the height H of support block 21,23 is the lowest surface of pump case 5 from pallet (or ground Base) 26 the height of degree left of upper surface.The inside of support block 21,23 can also be hollow.In this case, turning into The construction for making the face of support block 21,23 be formed by sheet material, the thickness of the sheet material is more than the 1% of length L.
As illustrated by the introduction, multiple impellers 2 are configured in housing 5 (reference picture 16).When multiple impellers 2 When being rotated together with the rotation with rotary shaft 1, the liquid such as water after being pressurizeed through an impeller 2 is further by next impeller 2 Pressurization, repeats such pressurization based on impeller 2, finally reaches maximum pressure in outlet 4.
Because multiple impellers 2 are arranged towards equidirectional, so the pushing away for producing because of the pressure differential between adjacent impeller 2 Power is superimposed according to the piece quantity of impeller 2, produces big thrust.The thrust passes through the (ginseng of bascule 7 in multistage pump 100 According to Figure 16) and cancel out each other, a certain degree of thrust however can be still remained in the running.The residual thrust is by thrust bearing 9A (reference picture 16) is supported.Thrust bearing 9A stator side is fixed in pump case 5.Pump case 5 be supported by pedestal 21,23 Hold, support block 21,23 is fixed on the upper surface of pallet 26.
Thrust depends on the pressure oscillations of liquid such as the water that is supplied by pump 100 and due to using the liquid discharged from pump 100 And produce pressure oscillation change.Strengthen for the rigidity of the support block 21,23 to supporting the thrust, this reality Applying the supporting construction of mode has strengthening part 29a, 30a of rectangle.Strengthening part 29a, 30a are seen from axially vertical direction There is rectangular shape when examining.Strengthening part 29a, 30a have symmetrical shape.Strengthening part 29a, 30a are by iron or concrete structure Into.Strengthening part 29a, 30a are welded or are fixed on by secure components such as bolts on support block 21,23 and pallet 26.
