Description

A kind of combined type fast self-priming centrifugal pump
Technical field
This utility model belongs to field of fluid machinery, more particularly to a kind of combined type fast self-priming centrifugal pump.
Background technology
Ordinary Centrifugal Pumps, it is very inconvenient if suction liquid level need in advance pour into liquid under impeller during startup.Meanwhile, it is Liquid is lived in pump internal memory, suction tube import need in advance install bottom valve, it is both inconvenient and cause very big hydraulic loss.Commonly certainly Heart pump is sucked away from, self-priming time is long, less efficient, pump is heavy and is not easy to move, complex operation.In the case of plateau, atmospheric pressure Power reduces, and the pressure of pump inlet is little, is easily caused the generation of pump cavitation phenomenon, pump is caused to damage, it is impossible to normal work.Common liquid Ring type self priming pump, due to pendular ring wheel and centrifugal wheel rotary work simultaneously, the efficiency of pump is relatively low, and power consumption is big.In sum, be meet with Upper self-priming, plateau, it is quick, simple to operate, less efficient, etc. many requirements, it is ensured that the multi-state of pump, safe and reliable, stable fortune OK, a kind of combined type fast self-priming centrifugal pump for integrating above-mentioned various functions is needed.
Utility model content
Technical problem in the presence of in order to solve background technology, the utility model proposes a kind of combined type fast self-priming from Heart pump, the pump group self-priming performance is good, and anti-cavitation performance is good, simple to operate, and energy consumption is low.
Technical solution of the present utility model is:A kind of combined type fast self-priming centrifugal pump, including the pump housing, its feature exists In:The pump housing include inducer 2, centrifugal pump impeller 4, mechanical seal structure 5, main shaft 6, pendular ring wheel 8, drive 9, electromagnetism from Clutch 10;
One end of the main shaft 6 is power intake, the other end of main shaft 6 successively with inducer 2, impeller 4, mechanical seal Structure 5, electromagnetic clutch 10 are fixedly connected;
The drive end of the electromagnetic clutch 10 is connected with main shaft 6, the driven end of electromagnetic clutch 10 successively with drive 9th, pendular ring wheel 8 is fixedly connected;
Also include centrifugal pump casing 1, the inducer 2, impeller 4 and mechanical seal structure 5 are arranged at centrifugal pump shell In body 1;Fluid is entered by the import of centrifugal pump casing 1 and passes sequentially through inducer 2, impeller 4 by outlet outflow.
The end of above-mentioned main shaft arranges spindle nose locking nut 3 and matching nut locked spacer, the spindle nose locking nut 3 pairs Inducer 2 carries out axial restraint.
Mechanical seal structure 5 is fixed by key and hole with back-up ring in above-mentioned centrifugal pump casing 1.
Above-mentioned inducer 2 and impeller 4 are driven with main shaft 6 by key;
Above-mentioned pendular ring wheel 8, drive 9 are driven with electromagnetic clutch 10 and main shaft 6 by key.
Electron pressure switch 11 is set at the pump discharge of above-mentioned centrifugal pump.
The front-end and back-end of above-mentioned impeller 4 arrange labyrinth collar.
This utility model has the advantages that:
1) this utility model combined type fast self-priming centrifugal pump from main material adopt light weight, the high material of hardness, Overall construction design is as far as possible compact, reduces pump weight;Electromagnetic clutch is reached and disengaged automatically after pressure by pressure switch control, It is simple to operate;Using centrifugal wheel plus pendular ring wheel construction so that maximum vacuum can be improved quickly in pump, and self-priming time drops significantly It is low, with there is fast self-priming ability, medium can be sucted in 1min/5m;
2) inducer is added before the impeller of pump;Inducer can produce lift, the pressure of pump inlet be improved, while inducer The anti-cavitation performance of itself is good, so installing inducer can reduce the net positive suction head of pump, improves the anti-cavitation performance of pump, i.e., Make the plateau pump group in hypo 5000m can also safe operation;
3) increased pendular ring wheel in pump mid portion;The operating of pendular ring wheel can quickly form certain vacuum, so Installing pendular ring wheel part can increase the vacuum that pump can reach, and reduce the time required for pump self-priming;
4) electromagnetic clutch is connected by drive with pendular ring wheel;When pump is started working, electromagnetic clutch closure, pendular ring wheel Rotate with pump;Throw-out-of clutch after pump completes self-priming (normal work), pendular ring wheel stops the rotation, and the power consumed on pump shaft has Effect is reduced, and efficiency rises, and saves the energy;
5) we are provided with electronic pressure switch at pump discharge, when pump is started working, i.e., pump discharge when self-priming starts Less than the setting value of electron pressure switch, electromagnetic clutch is closure state to pressure value, and pendular ring wheel can be driven to rotate;When pump is completed After self-priming, normal work when, outlet pressure can be higher than electron pressure switch setting value, electron pressure switch produce signal feedback To clutch, throw-out-of clutch, pendular ring wheel stops the rotation.Clutch also can on-site manual give signal disengaging, it is simple to operate;
As described above, this utility model provides a kind of combined type fast self-priming centrifugal pump, by many novel, practicality Design, achieves many beneficial effects, there is good application prospect and industrial value in military, industry, daily life.
Description of the drawings
Fig. 1 is this utility model combined type fast self-priming centrifugal pump structure schematic diagram;
1-housing, 2-inducer, 3-locking nut, 4-impeller, 5-mechanical seal structure, 6-main shaft, 7-support Frame, 8-pendular ring wheel, 9-drive, 10-electromagnetic clutch, 11-electron pressure switch;
Specific embodiment
This utility model is further illustrated with reference to the accompanying drawings and examples.
It is shown in Figure 1:Impeller 4 and inducer 2 are arranged on main shaft 6, inducer 2 is located at the front end of impeller 4, is luring Installation locking nut 3 and spindle nose screw stop packing ring compress inducer 2 and impeller 4 before guide wheel 2.The position of impeller 4 exists during installation In the outlet passage of housing 1, its effect is that have pressure to go out by the runner of housing 1 in the medium acted on through impeller 4;Inducer 2 Position can allow medium just acting on through inducer 2 before being acted on by impeller 4 in the water inlet pipe of housing 1, raising anti-cavitation Performance.It is fixed together with bracket 7 between housing 1 and electromotor, it is ensured that the run stability of unit.
The active part of electromagnetic clutch 10 is connected with main shaft 6, and after electromagnetic clutch 10 is connected, electromagnetic clutch 10 is driven Part contacts with drive 9, and electromagnetic clutch 10 imparts power to pendular ring wheel 8 by drive 9, rotates pendular ring wheel 8, Negative pressure is produced, increases vacuum in pump, improve the suction lift and self-priming time of pump.Pressure switch is housed at outlet of centrifugal pump 11, when centrifugation pump portion runs well, when pump discharge pressure reaches the setup pressure value of pressure switch, the transmission letter of pressure switch 11 Number give electromagnetic clutch 10, the secondary part and drive 9 for making electromagnetic clutch 10 is separated from, so that the part of pendular ring wheel 8 Quit work, and then improve the work efficiency of pump, reducing energy consumption.Meanwhile, electromagnetic clutch 10 also can manually give signal, to Control running on and disengagement for electromagnetic clutch 10.
The drive end of electromagnetic clutch 10 is held tightly on pump main shaft 6, and after electromagnetic clutch 10 is installed, strict detection master The perpendicularity of axle 6 and electromagnetic clutch 10.
In view of medium reveal, the front end of impeller 4, rear end install labyrinth collar, on main shaft 6 be located at impeller 4 it Mechanical seal structure 5 is installed afterwards.
