Abstract
The utility model discloses a kind of multi-stage pipeline pumps, including outer cylinder, outer cylinder both ends are separately installed with intake end cover and water outlet end cap, the outer barrel is provided with pump motor, the motor shaft of the pump motor runs through the pump motor, motor shaft both ends are separately installed with impeller assembly, the impeller assembly by conducting element, conducting element end cover board and conducting element in impeller form, the motor shaft both ends are connect with the impeller respectively.In this multi-stage pipeline pump, impeller assembly is respectively arranged in motor shaft both ends, the shaking of motor shaft when greatly reducing water pump operation, keep water pump operation more stable, water pump is integrally easily assembled, and impeller sets, without axle sleeve, equipment fault caused by avoiding due to axle sleeve abrasion keeps equipment relatively reliable.
Description
Technical field
The utility model relates to a kind of pump, especially a kind of pipeline pump.
Background technique
Traditionally, the pipeline pump used as deep well pump be all using single pump form, with earth's surface water level decreasing, lift compared with
Also high lift pipeline pump can only be used when high.In the prior art, Gao Yangcheng pipeline pump needs to use motor shaft by multiple impellers
Group is connected in series, therefore the motor shaft of this pipeline pump is long, and multiple impeller sets are installed in pipeline pump side, pipeline
Motor shaft shaking is larger when pump running, stability is poor, and will lead to axle sleeve Fast Wearing, and fault of water pump is caused to lose
Effect.
Summary of the invention
The technical problem to be solved by the present invention is to provide a kind of multi-stage pipeline pumps, and the stabilization of water pump operation can be improved
Property, prevent equipment fault from failing.
In order to solve the above-mentioned technical problem, a kind of multi-stage pipeline pump of the utility model, including outer cylinder, outer cylinder both ends difference
Intake end cover and water outlet end cap are installed, the outer barrel is provided with pump motor, and the motor shaft of the pump motor runs through the pump
Motor, motor shaft both ends are separately installed with impeller assembly, the impeller assembly by conducting element, conducting element end cover board and lead
The impeller composition in part is flowed, the motor shaft both ends are connect with the impeller respectively.
The pump motor both ends are separately installed with dynamic seal, which is sleeved on the motor shaft, dynamic sealing
It is provided with holddown spring between part and the impeller assembly, the sealing effect to pump motor is kept when running equipment,
Enable equipment operation relatively reliable.
The pump motor is permanent magnetic brushless, and the revolving speed and pump efficiency of impeller can be improved, and is conducive to reduce water pump
Volume.
The pump motor includes stator seat, is provided with rotor on the outside of the stator seat, the motor shaft is connect with rotor, described
The long axis hole that there is power supply arbor to pass through in stator seat, stator seat outside are connected and fixed with the outer cylinder.Pump motor is turned using outer
Minor structure can simplify the mounting structure of motor, reduce production cost.
The pump motor end is provided with bearing support, is equipped with motor outer between the bearing support and the stator seat, makes
The overall structure of product is more stable, and convenient for assembling.
The beneficial effects of the utility model are: impeller assembly is respectively arranged in motor shaft both ends in this multi-stage pipeline pump,
The shaking of motor shaft when greatly reducing water pump operation, keeps water pump operation more stable, and water pump is integrally easily assembled, and impeller sets
Without axle sleeve, equipment fault caused by avoiding due to axle sleeve abrasion keeps equipment relatively reliable.
Detailed description of the invention
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
Fig. 1 is the structural schematic diagram of the utility model；
