Description

A kind of rotor part of sewage MODEL VERTICAL MULTISTAGE PUMP
Technical field
The utility model relates to a kind of rotor part of MODEL VERTICAL MULTISTAGE PUMP, particularly relates to a kind of rotor part of sewage MODEL VERTICAL MULTISTAGE PUMP.
Background technique
Existing rotor components of vertical multi-stage pump generally relies on the screw thread on rotary main shaft and nut to be fastened on rotary main shaft by the rotor part such as impeller, axle sleeve, and the transmission between water Pump and Electromotor relies on other pump coupler to realize again.Different according to screw thread position on rotary main shaft, existing rotor components of vertical multi-stage pump locking device can be divided into again following two classes:
One, the screw thread on rotary main shaft is arranged on the front end of first stage impeller import.The stress during work of this design consideration rotary main shaft, by the stressed minimum position when rotary main shaft works of the Design of Screw Thread on rotary main shaft, the designing requirement that impeller joint rotary main shaft diameter is little as far as possible can be met, both be conducive to the hydraulic performance ensureing water pump, be conducive to again the material saving rotary main shaft.But from now on when pump maintenance and renewal part, need whole water pump to disintegrate by first stage impeller, workload is large, labor intensity is high, do not meet human oriented design principle.
Two, the screw thread on rotary main shaft is arranged on the rear end of impeller.This design assembling is all more convenient with maintenance, in existing product, adopt the most a kind of mode, but this design consideration assembly technology requirement, impeller joint rotary main shaft diameter must be greater than the diameter of thread on rotary main shaft, the core diameter of thread on rotary main shaft must be greater than again the rotary main shaft diameter at pump coupler place, and the rotary main shaft diameter at coupling place is stressed maximum, therefore, impeller joint rotary main shaft diameter must be increased, both be unfavorable for the hydraulic performance ensureing water pump, be unfavorable for again the material saving rotary main shaft.
Existing rotor components of vertical multi-stage pump is generally all provided with bar axle and axle sleeve and is arranged on MODEL VERTICAL MULTISTAGE PUMP inlet segment sliding bearing cooperating in first stage impeller import front end.
The advantage of this structure is: 1, one end of rotor components of vertical multi-stage pump is provided with sliding bearing structure, and employing two supports structure is conducive to stability during multi-stage pump rotor component working; 2, design is shaped, and parts Standardization, generalization degree are high, use the most extensive.
The defect of this structure is: 1, first stage impeller import front end is provided with bar axle and axle sleeve, needs the water inlet area strengthening first stage impeller, breaks the versatility of ring head, secondary impeller part, sacrifices the efficiency of first stage impeller; 2, because the lubrication of sliding bearing relies on fed sheet of a media itself, when fed sheet of a media be sewage or easily fouling medium time, easily there is plugging fault in sliding bearing inlet opening, destroys lubrication and the flushing of sliding bearing, sliding bearing is run in slough, shortens the working life of sliding bearing.
Summary of the invention
The utility model wishes to provide one to possess single segment structure separate support function; Sewage and easy fouling medium can be carried; The designing requirement that impeller joint rotary main shaft diameter is little as far as possible can be met, both the hydraulic performance ensureing water pump had been conducive to, be conducive to again the material saving rotary main shaft, and, assembling is convenient with maintenance, do not need to rely on the screw thread on rotary main shaft and nut to be fastened on rotary main shaft by the rotor part such as impeller, axle sleeve, by the rotor part of locking with a kind of sewage MODEL VERTICAL MULTISTAGE PUMP of transmission device integrated design.
The rotor part of this sewage MODEL VERTICAL MULTISTAGE PUMP of the present utility model is made up of rotary main shaft, first stage impeller, secondary impeller, axle sleeve, shaft block ring, self-locking pump coupler and other rotor part, it is characterized in that: described rotary main shaft all adopts same diameter by first stage impeller installation place; Described rotary main shaft and front end, first stage impeller installation place are provided with circlip groove on axle; Described first stage impeller entrance point wheel hub is provided with circlip groove on first stage impeller; First stage impeller, secondary impeller, axle sleeve and other rotor part to be fastened on rotary main shaft on shaft block ring by described self-locking pump coupler; Described rotary main shaft is provided with a technique interior threaded hole by pump coupler end.
Wherein, self-locking pump coupler is made up of expansion set, lower gland, pump coupler, bolt etc., it is characterized in that: described lower gland internal taper hole is furnished with an expansion set, and is assembled into one by bolt and rotary main shaft, pump coupler.
Working principle of the present utility model is:
1, shaft block ring to be inserted on the axle on rotary main shaft after circlip groove, just to constitute a firmly shoulder block on axle;
2, on rotary main shaft, be inserted in the rotor parts such as first stage impeller, secondary impeller, axle sleeve by assembly technology, be finally respectively charged into all accessories of self-locking pump coupler;
3, by be arranged on technique interior threaded hole on rotary main shaft and additional technique pressing plate and hold-down bolt can very easily by first stage impeller, secondary impeller, axle sleeve, etc. rotor part and self-locking pump coupler be fastened on rotary main shaft;
4, just can by self-locking pump coupler tight joint on rotary main shaft by locking pump coupler and pressing down the bolt put;
5, after pulling down technique pressing plate and hold-down bolt, a kind of rotor part of sewage MODEL VERTICAL MULTISTAGE PUMP assembles and just completes.
The utility model product effect major embodiment compared with prior art products is following:
1, compared with existing two kinds of rotor components of vertical multi-stage pump locking devices, the utility model product can not only meet the designing requirement little as far as possible of impeller joint rotary main shaft diameter, be conducive to the hydraulic performance ensureing water pump, and assembling is convenient with maintenance.
2, rotary main shaft all adopts same diameter by first stage impeller installation place, there is no the components such as screw thread, tool withdrawal groove and shoulder block, not only simplify the processing technology of rotary main shaft, ensure that the quality of processing of rotary main shaft, and decrease the materials consumption of rotary main shaft, what enhance rotary main shaft is subject to force intensity.
3, self-locking pump coupler adopts expansion-joints, operation torque is transmitted jointly by expansion set and flat key, bears axial force ability more by force, there will not be at a high speed and pulse frequently between pump shaft and coupling, pump shaft and guide bearing friction can not be caused, occur that pump shaft bends the accident even ruptured.
4, the rotor part of this sewage MODEL VERTICAL MULTISTAGE PUMP is different from conventional construction product, single segment structure has possessed separate support function, do not need the inducer again before first stage impeller that bearing is set, therefore the import before first stage impeller can not arrange bar axle, the water inlet state of first stage impeller can be improved, do not need the water inlet area strengthening first stage impeller, the versatility of head, secondary impeller part can be ensured, and can pump efficiency be improved.
5, separate support function has been possessed when the rotor part of this sewage MODEL VERTICAL MULTISTAGE PUMP axle sleeve be arranged on rotary main shaft runs with the bearing be arranged on the intermediate clapboard of stage casing.Every one stage impeller has guide bearing to support, and rotor operation is more stable; Guide bearing two ends pressure reduction is single-stage impeller lift, and lubrication is more reliable, goes for conveying sewage and easy fouling medium.
