Abstract
The utility model provides a kind of double centrifugal pump groups, including the first water pump, the second water pump, motor for double-ended drive and shaft coupling, the lift of first water pump is more than the lift of the second water pump, the power transmission shaft at motor for double-ended drive both ends is connected by shaft coupling with the first water pump and the second water pump drive respectively, after solving existing pump group structure determination, the lift of water pump can only be run in limited scope, the problem of can not being varied as desired in pump group lift.The utility model belongs to rural water field.
Description
Technical field
A kind of centrifugal pump group is the utility model is related to, belongs to supply equipment field.
Background technology
Rural area lift pumping station be for will from the relatively low pond of physical features water suction come up, it is higher along Pipeline transport to physical features
Local residential block, typically using centrifugal pump group provide power, water pump is fetched water in reservoir, because the water level of reservoir becomes
Change, the lift of pumping plant also changes accordingly；Existing centrifugal pump group, there is single-stage pump and multistage pump, and water pump is arranged in motor
One end, after pump group structure determination, the lift of water pump can only be run in limited scope.After the lift of pumping plant changes,
Water pump operation will deviate from high efficient district, so as to cause pump efficiency to reduce or can not run.
The content of the invention
The purpose of this utility model is：A kind of double centrifugal pump groups are provided, after solving existing pump group structure determination, water pump
Lift can only be run in limited scope, the problem of pump group lift can not be varied as desired in.
To solve the above problems, intend using such a double centrifugal pump groups, including the first water pump, the second water pump, Double shaft-extension
Motor and shaft coupling, the lift of the first water pump are more than the lift of the second water pump, and the power transmission shaft at motor for double-ended drive both ends passes through respectively
Shaft coupling is connected with the first water pump and the second water pump drive.
Change the method for lift using above-mentioned pump group, it is specific as follows：
The water level of observation water intaking reservoir, if water level is higher, less second water pump of lift is accessed in supply channel, and
It is connected by shaft coupling with motor for double-ended drive, starts motor for double-ended drive to drive the second water pump to supply water；When water level in water intaking reservoir
When relatively low, the second water pump is substituted to access in supply channel with the first water pump, and pull down between the second water pump and motor for double-ended drive
Shaft coupling, the first water pump is connected with motor for double-ended drive by shaft coupling, starts motor for double-ended drive to drive the first water pump to supply water
.
Compared with prior art, the utility model is fitted with the water pump vane of different lifts at the both ends of motor,
Changed according to pumping plant lift, pass through dismounting（Connection）Band jackshaft rapid coupler, connect required water pump and motor,
Corresponding water pump operation is put into, to improve the efficiency of pumping plant unit and security and stability.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
, below will be by accompanying drawing to utility model to make the purpose of this utility model, technical scheme and advantage clearer
It is described in further detail.
Embodiment：
Reference picture 1, the present embodiment provide a kind of double centrifugal pump groups, including the first water pump 1, the second water pump 2, motor for double-ended drive
3 and shaft coupling 4, the lift of the first water pump 1 is more than the lift of the second water pump 2, and the power transmission shaft at the both ends of motor for double-ended drive 3 passes through respectively
Shaft coupling 4 is connected with the first water pump 1 and the second water pump 2.
It is as follows that it changes the method for lift：
The water level of observation water intaking reservoir, if water level is higher, less second water pump 2 of lift is accessed in supply channel,
And be connected by shaft coupling 4 with motor for double-ended drive 3, start motor for double-ended drive 3 to drive the second water pump 2 to supply water；When water intaking reservoir
When interior water level is relatively low, substituted with the first water pump 1 in the second water pump 2 access supply channel, and pull down the second water pump 2 and Double shaft-extension electricity
Shaft coupling 4 between machine 3, first water pump 1 is connected with motor for double-ended drive 3 by shaft coupling 4, starts motor for double-ended drive 3 to drive
Dynamic first water pump 1 supplies water.
