Abstract
The utility model relates to a pump, in particular to a vertical self-absorbing centrifugal pump. The utility model aims at providing a vertical self-absorbing centrifugal pump. The technic proposal is as follows: the vertical self-absorbing centrifugal pump is composed of a pump body, a gas-liquid disconnecting gear, a shaft seal component, a pump shaft, a bearing, a shaft joint, a link span, a motor, a rotor support, a siphon destructor, an impeller, a frame and a base. The utility model is characterized in that the pump body adopts a vertical structure whose input port and output port are both positioned at the superior part of the side of the pump body, the motor is arranged on the connecting frame which is positioned at the top of the pump body, a rotating shaft of the motor is connected with the pump shaft by the shaft joint; the pump shaft is flexibly fixed on a rotating shaft base whose upper end adopts a bearing for location and connection while lower end adopts a shaft seal component for connection, the lower end of the pump shaft is provided with an impeller; the pump body is internally provided with a frame, the gas-liquid disconnecting gear is fixed on a frame, and the impeller and the gas-liquid disconnecting gear are in a movable fit. The utility model, thanks to the adoption of a vertical structure and siphon destructor, has the advantages of that the volume is small and the shortcoming that water must be fed before starting is artfully solved.
Description
Technical field:
The utility model relates to a kind of pump, particularly relates to a kind of vertical self-priming centrifugal pump.
Technical background:
At present, itself does not have self-absorption function Ordinary Centrifugal Pumps, before each the startup, all needs priming petock in pump, and it is very inconvenient to use, and is not suitable for the remote-controlled operation remote control.And existing self-priming centrifugal pump all adopts additional device, adopts additional device that it is injected water before startup.And existing self-priming centrifugal pump mostly is horizontal type structure.Bulky, the self-priming height is no more than 4.5m.
Summary of the invention:
The purpose of the utility model provides a kind of vertical self-priming centrifugal pump with self-absorption function.
The utility model is achieved in that a kind of vertical self-priming centrifugal pump, constitute by the pump housing 1, gas-liquid separation device 2, shaft sealing member 3, pump shaft 4, bearing 5, coupling 6, link press span 7, motor 8, rotor bearing 9, siphon destroying device 10, impeller 11, support plate 12 and base 13, it is characterized in that: the described pump housing 1 adopts the vertical and cylindrical structure, its suction port and delivery outlet are positioned at the top of the pump housing 1 side, motor mounting is on the pump housing 1 top link press span 7, and the rotating shaft of motor 8 connects with pump shaft 4 by coupling 6; Described pump shaft 4 activities are fixed on the rotor bearing 9, and its upper end adopts bearing 5 location to connect, and its lower end adopts shaft sealing member 3 to connect, and the bottom of pump shaft 4 is provided with impeller 11; Be provided with support plate 12 in the described pump housing 1, gas-liquid separation device 2 is fixed on the support plate 12, and described impeller 11 and gas-liquid separation device 2 are movingly.
Described siphon destroying device 10 adopts solenoid valve.
The utility model has the advantages that: owing to adopt vertical structure and siphon destroying device 10, therefore not only volume is little, and has solved the phenomenon of necessary water filling before startup dexterously.
Description of drawings:
Fig. 1: be structural representation of the present utility model.
Specific embodiment:
The utility model is by the rotor bearing 9 of the pump housing 1 that is welded, smart casting and the shell that base 13 is formed self-priming pump; Form the rotor of self-priming pump by pump shaft 4, impeller 11, rotor relies on bearing 5 to be supported on the rotor bearing 9, and rotor is connected with motor 8 by coupling 6, just can drive rotor high-speed and rotate behind motor start-up.Be provided with the powerful gas-liquid separation device 2 of stator formula in the outlet port of impeller 11, the rotor of high speed rotating is under the synergy of the centrifugal force of impeller 11 and stator formula gas-liquid separation device 2, make the liquid storage in the pump housing constantly circulate, stir, clash into, allow liquid fully mix with gas, then through stator formula gas-liquid separation device 2 with gas and liquor separation, and through delivery side of pump discharge gas, gas in the pump housing and inlet pipeline is discharged gradually, when forming the suction vacuum, liquid just can be sucted slowly from low level, finally reaches normal operation continuously; The powerful gas-liquid separator of stator formula not only can make gas and liquor separation, separate out, and after dropping into normal operation, also has the effect that the kinetic energy of impeller outlet is converted to the pressure energy, makes the running of pump high efficiency.When pump quits work,, the liquid in the pump housing and the pipeline is all inhaled sky, do not have liquid storage just can not start running in the pump housing, can not produce self-absorption function because pump in a high position, is transferred liquid at low level, thereby wink promptly produces siphonage.For this reason, the utility model is provided with solenoid valve as quick siphon destroying device 10 in the inlet of pump, at the out-of-work solenoid valve of opening simultaneously of pump, siphonage is destroyed, make and preserve certain amount of fluid in the pump housing forever, thereby make pump can keep self-absorption function, can start repeatedly lastingly, put into operation safely and reliably.To be transferred liquid and to spill in order not allow from the slit between housing and the rotor, the utility model is provided with the shaft sealing member 3 of high reliability, this mechanism is made up of off-load ring and mechanical seal, the off-load ring can reduce the working pressure of mechanical seal greatly, a whole set of mechanical seal is totally-enclosed again in oil pocket, it is lubricated fully reliably that sealing surface is obtained, and unlikely wearing and tearing also increase the service life greatly, thereby guarantee its reliable sealing function.Shell of the present utility model and rotor are made by multiple resistant material, so also possess corrosion-resistant function.
