In addition, consist of the live axle 22 of motor 20 and the running shaft 34 of impeller 30 by split, thus, can use respectively different materials.For example, the material manufacturing that live axle 22 usefulness carbon steel etc. are cheap, the expensive material of only having running shaft 34 usefulness stainless steels etc. to have corrosion resistance is made, and then can reduce cost.
Supply with to motor 20 by power cable 12 from the electric power that is arranged on control panel on the ground, live axle 22 and rotor 25a rotate together, and impeller 30 and live axle 22 rotate together.Like this, the water that sucks from the suction port 38a of suction casing 38 after guide blades 32 rectifications by pump case 31, is discharged to the path 2 that draws water from the downstream of case cover 39 when circulation stream 33, upwards flows in the path 2 that draws water, and discharges to discharge tube 3.
Like this, in the present embodiment, case cover 39, framework ABAP Adapter 40 and coupling 42 play a role as the adjustment component that post 1, electric machine casing 21, pump case 31 position relationship is according to the rules configured usefulness when combination motor 20 and impeller 30.
Below, be elaborated to adjusting member.
And lift as required and flow are selected the impeller 30 of optimal type.The required power of the rotation of impeller 30 is not only the part that impeller 30 does work, and also comprises by the stream friction, as the part of the caused pressure losses of proterties such as viscosity, temperature of the water of the object that draws water.
Therefore, motor 20 is with respect to making the needed power of selecteed impeller 30 rotations select to access suitable surplus.Post 1 is selected a kind of like this type, and this type has considers frictional loss and the bore that flow is circulated under suitable flow velocity.
The rotating speed of the flow of diagonal pumps 10 and motor 20 is proportional, its lift and rotating speed square proportional.The axle power of motor 20 and the product of flow and lift are proportional.Thereby, even identical impeller 30 by changing the type of motor 20, perhaps, even identical motor 20 passes through to change the type of impeller 30, also can change lift, flow thus.
Shown in Fig. 5 (b), impeller is divided into 3 stage types, thereby by standardization, impeller 30A, 30B, 30C constitute and be set as blade, pump case 31A, 31B, 31C, suction housing and increase successively, can tackle high-lift or large flow.
In the present embodiment, be set as respectively 3 types as motor 20A, 20B, 20C and impeller 30A, 30B, 30C are the same, can access 9 diagonal pumps by their combination.
For example, and impeller 30A is compared with the submersible pump that motor 20B combines, diving lift of pump and the flow of selecting impeller 30B and motor 20B to combine become greatly.With motor 20B is compared with the diagonal pumps that impeller 30B combines, oblique flow lift of pump and flow that motor 20C and impeller 30B are combined become large.
Difference lift and flow as required selected optimal motor and impeller from motor 20A, 20B, 20C and impeller 30A, 30B, 30C, make up its electric machine casing 21 and pump case 31 formation diagonal pumps 10, these diagonal pumps 10 are suspended in the selected post 1 and construct the pillar submersible pump.
At this moment, when the position relationship of post 1, electric machine casing 21, pump case 31 was inappropriate, then the pressure loss increased in the stream between post 1 and electric machine casing 21, pump case 31, and existence can't obtain the situation of desirable performance.
For example, by the combination of selecteed motor 20 and impeller 30, then can't obtain desirable lift and flow when the pressure loss increases in the stream between the joining portion of motor 20 and impeller 30, post 1 and electric machine casing 21, the pump case 31.In this case, by adjustment component, with position relationship configuration post 1, electric machine casing 21, the pump case 31 of regulation.
Below, the framework ABAP Adapter and the coupling that comprise about the adjusting parts are elaborated.
By the motor 20 selected according to lift or flow and the combination of impeller 30, the radial dimension that the joint of the joint of electric machine casing 21 and pump case 31 then may occur has more different situation.In this case, because in separately the larger change of joint flow path cross sectional area, so that the pressure loss becomes is large.
For example, in the described diagonal pumps 10A of Fig. 6 (a), the joint of the pump case 31 of impeller 30 is less with respect to the joint diameter of the electric machine casing 21 of motor 20.Therefore, framework ABAP Adapter 40A by the shape from impeller 30 sides to motor 20 side enlarged, connect mutually different electric machine casing 21 and pump case 31 of radial dimension, the rapid enlarged of the flowing path section by relaxing each joint prevents that the pressure loss from becoming large.
In the described diagonal pumps 10B of Fig. 6 (b), the joint of the pump case of impeller 30 is larger with respect to the joint diameter of the electric machine casing of motor 20.Framework ABAP Adapter 40B by the shape from impeller 30 sides to motor 20 side diameter reduction, connect mutually different electric machine casing 21 and pump case 31 of radial dimension, the rapid enlarged of the flowing path section by relaxing each joint prevents that the pressure loss from becoming large.
Like this, framework ABAP Adapter 40A, 40B impel flowing smoothly of fluid, and make its angle of inclination with respect to the axis of rotation of impeller 30 be set in about 30 degree in order to relax rapid enlarged or the diameter reduction of flow path cross sectional area.From the rapid enlarged of mitigation flow path cross sectional area or the viewpoint of diameter reduction, this angle of inclination is preferably set to for example below 45 degree.
In addition, as the described diagonal pumps 10C of Fig. 6 (c), the joint diameter of the pump case of the joint of the electric machine casing of motor 20 and impeller 30 is roughly the same.Framework ABAP Adapter 40C constitutes the identical shape of 20 side diameters from impeller 30 sides to motor, connects smoothly joint separately, thereby prevents that the pressure loss from becoming large.
In the coupling 42, diameter at the joint of the joint of electric machine casing 21 and pump case 31 has in the more different situation, for the angle of inclination that makes framework ABAP Adapter 40 relative impellers 30 axle center is below 45 degree, need to be with the axis direction of the cylindrical part 40a of framework ABAP Adapter 40 apart from increase.
Even in this case, lead to distance by adjusting inserting of live axle 22 and running shaft 34 relative coupling 42, can adjust the distance between the axial end of live axle 22 and running shaft 34.That is, constitute can be according to the length adjustment length along the axis direction of impeller 30 for framework ABAP Adapter 40.
In addition, also can not change coupling 42 and constitute: because contact liq and can use the live axle of the motor 20 that cheap material makes to lengthen not, use the running shaft 34 of the impeller 30 of the material manufacturing with intensity at high price to shorten, can be according to the length adjustment length of framework ABAP Adapter 40 along the axis direction of impeller 30.
In addition, adjustment component can not comprise coupling yet and only is made of the framework ABAP Adapter.
From Fig. 7 (a) to Fig. 7 (c), show following content: the impeller sets of multistage type manufacturing is set, the impeller 54A that each type is different, diagonal pumps 50A, 50B, the 50C that 54B, 54C assemble are set in the motor in the motor unit that multistage type makes, certain same model in the output area of each regulation in the range of flow of each regulation.In addition, the record of all having omitted post among any diagonal pumps 50A, 50B, the 50C about having the formation with diagonal pumps shown in Figure 2 10 identical functions, has been omitted explanation.
Diagonal pumps 50A shown in Fig. 7 (a) has: be housed in the motor 52A in the electric machine casing 51A that constitutes vertical tubular; And rotation is housed in the impeller 54A in the pump case 53A etc. freely.The underpart of the live axle 55A of motor 52A below be through with lower tray 21b, its top is equipped with impeller 54A.Has framework ABAP Adapter 56A between electric machine casing 51A and the pump case 53A.
Diagonal pumps 50C shown in Fig. 7 (c) has the impeller 54C with the motor 52A of the same type of diagonal pumps 50B and the type larger than impeller 54B.Has framework ABAP Adapter 56C between the electric machine casing 51A of diagonal pumps 50C and the pump case 53C.
When the position relationship of electric machine casing and pump case is inappropriate, the pressure loss increases in the stream between post and electric machine casing, the pump case, existence can't obtain the situation of desirable performance, and utilize framework ABAP Adapter 56A, 56B, 56C, by with the position relationship configuration according to the rules of electric machine casing and pump case, can draw water with being well on and can guarantee flow and lift.
Like this, diagonal pumps 50A, 50B, 50C do not possess coupling, and framework ABAP Adapter 56A, 56B, 56C play a role as the adjustment component that electric machine casing 51 and pump case 53 is configured in the position relationship of regulation.In addition, owing to not having a coupling, so, to assemble respectively with motor and impeller and integrated situation is compared, assembling operation needs spended time, but produces the advantage that does not need coupling, gathering hole, parts number of packages to reduce.
In addition, the lift of diagonal pumps 10 and flow are not limited to combination change lift and the flow that utilizes motor 20 and impeller 30.Even the combination of identical impeller 30 and motor 20, thus the rotating speed of motor adjusted by adjusting frequency with Variable Control, can change lift, flow.In addition, even motor 20 is identical, lift and flow also can change with respect to the setting angle of sharf 30b according to the blade 30a of impeller 30.
When making the flow increase of diagonal pumps 10 at the type that does not change impeller 30, the diameter that need to select post 1 according to flow is larger parts also, in this case, shown in Fig. 8 (a), there is the situation that the poor D of larger ladder is arranged between the discharge portion of pump case 31 and the post 1.In the part of the poor D of ladder because larger variation occurs in flow path cross sectional area, so, in the discharge portion of pump case 31, shown in the dotted arrow of Fig. 8 (a), the mobile confusion reigned of water, peel off, vortex, increase in this partial pressure loss.
Therefore, shown in Fig. 8 (b), the exhaust port of pump case 31 has case cover 39.By case cover 39 being connected to the exhaust port (terminal side) of pump case 31, make the distribution channel enlarged little by little from the exhaust port of pump case 31 to the fluid of post 1 interior conveying, thus, the flow path cross sectional area that can suppress from pump case 31 to post 1 interior mobile fluid sharply changes, and can prevent the increase of the pressure loss, pump efficiency is descended is suppressed at bottom line.
That is, case cover 39 is as playing a role for the adjustment component that post 1, electric machine casing 39, pump case 31 is configured in the position relationship of regulation.
In addition, also can cut compare with the internal diameter of post 1 edge, downstream side of large case cover of external diameter, it is poor to adjust with the ladder of post 1.In the poor little situation of ladder between pump case 39 and the post 1, also can not have housing.
Like this, when not changing motor, impeller type and changing flow, utilize case cover, post, electric machine casing, pump case can be configured in the position relationship of regulation.
Because the position relationship of pump case 63 and post 1 can enough case cover 67 be adjusted, so can design respectively pump case 63 and post 1.
Namely, according to pillar submersible pump of the present utility model, for the motor of selecting according to lift and flow and the combination of impeller, as long as be assembled with post and electric machine casing and pump case are configured in the adjustment component that the position relationship of regulation is used, need not to have above-mentioned framework ABAP Adapter, coupling for driving shaft, all parts of case cover, as long as combination has any adjustment component, in addition, as long as be assembled with any two adjustment component that form of combination.
In the above-described embodiment, as the pillar submersible pump, the diagonal pumps that are the suspention setting of vertical take live axle in post describe as example, but are not limited to this.The output shaft of submersible pump also can be the direction except vertical, for example can be the diagonal pumps of the transverse axis of along continuous straight runs configuration.In addition, being not limited to diagonal pumps, also can be the submersible pumps such as axial-flow pump, centrifugal pump.In addition, submersible pump can be applicable to water supply or the employed submersible pump of draining in the every field such as water supply, draining, industrial water.
By preparing needed adjustment component when assembling normalized motor and impeller in advance, thus, even the submersible pump of combination in any also can be made cheaply, utilize in addition adjustment component, arbitrarily post, electric machine casing, pump case suitably can be configured in the position relationship of regulation, can easily can obtain the diagonal pumps of various flows, lift.
Utilize adjustment component, owing to post, electric machine casing, pump case can be configured in the position relationship of regulation, so, when standardized electric motivation and impeller, can design respectively.
Any is an example of the present utility model in the above-mentioned mode of execution, and the utility model is not limited to this record, and the concrete formation of each several part also can be done suitable change design in the scope that can reach action effect of the present utility model, and this is self-evident.
