Weigh axial force.Casing cylinder pressure-bearing, barrel lenght depend on the performance parameter requirement and operating reliability design of product；Bearing housing
Internal bearing relies on the carry out self-lubricating of internal disc.
Existing horizontal cylinder bag multistage pump mainly has several specifications such as 40,50,80,100,125,150,200.With minimum
40 pump-type hydraulic models, its minimum specified applying working condition：Flow Q=22m3/ h, single-stage lift H=35m.When applying working condition is in flow
Q=6m3During/h single-stage lifts H=40m or so, it is necessary to which drawing substantial amounts of backflow could meet to use, and lack a kind of suitable horizontal cylinder
Bag pump pump-type meets this applying working condition.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of horizontal cylinder bag multistage pump of low discharge, has more excellent
The performance parameter of the impeller of change, it disclosure satisfy that larger range of flow and single-stage lift operating mode.
Technical scheme is as follows used by the utility model solves above-mentioned technical problem：
A kind of horizontal cylinder bag multistage pump of low discharge, including pump shaft, impeller and stator are provided with pump shaft, and impeller includes head
Wheel and next round, it is characterised in that：The blade of the first run is six pieces, and the blade of next round is seven pieces.
In six pieces of blades of the first run, three pieces are compared with linear leaf, and three pieces are compared with short blade, and compared with linear leaf and shorter leaf in addition
Piece is spaced apart.
The subtended angle of blade of impeller 108 is 108 degree.
The width of the blade passage of impeller 108 is 5-6mm.
Good effect of the present utility model is：
The utility model, by reducing the inlet size of cylinder, redesigns the waterpower of impeller on the basis of DSG40-180
Model and stator hydraulic model reach requirement.
The utility model is designed according to existing horizontal cylinder bag Multi-stage pump structure, and retaining, existing horizontal cylinder bag is multistage
Curve guide impeller has been carried out under the conditions of pump superior structural；The utility model has expanded the type spectrum of horizontal cylinder bag multistage pump series pump-type,
Having filled up horizontal multi-stage barrel bag pump does not have the blank of suitable pump-type in low discharge scope, expands being applicable for horizontal multi-stage barrel bag pump
Scope.Its performance parameter completely that meet flow Q=6m3, single-stage lift H=40m working condition requirement.
The utility model provides a kind of efficient horizontal multi-stage barrel bag pump of small flow, reduces disappearing for the energy
Consumption, reduces operating cost.
Specifically, the utility model has redesigned the hydraulic sizes of impeller, by the original impeller blade quantity first run five
Piece, six pieces of blades of next round be adjusted to the first run three grow three short blade patterns, the pattern of seven pieces of blades of next round；The primary blades bag of impeller
Angle is adjusted to 108 degree by original 118 degree, and the width of blade passage is adjusted to meet the 5- that casting requires by original 8-9mm
6mm, so that the performance parameter of pump meets design requirement.
