Abstract
The utility model is a kind of small flow vertical type multilevel barrel bag pump, and the inlet size importing and exporting section is φ 65 mm, and outlet size is φ 35 mm; The inlet diameter (D) of impeller is φ 65 mm, and inlet's hub diameter of impeller is φ 50 mm, and the mounting hole diameter of impeller is φ 40; The blade quantity of impeller is six, and the exit width of impeller is 4mm.The size of the import and export bore of section is imported and exported by change, redesign impeller hydraulic model, change the inlet/outlet size of impeller, adjustment impeller intra vane quantity, blade twist form etc., change the performance parameter of impeller, provide a kind of small flow high efficiency vertical type multilevel barrel bag pump, there is minimizing energy consumption, reduce the outstanding feature of user cost.
Description
Technical field
The utility model relates to a kind of vertical type multilevel barrel bag pump.
Perform the vertical type multilevel barrel bag pump (VS1 and VS6) of GB/T3215-2007 small flow.Its performance parameter flow Q=6m
3, single-stage lift H=35m.
Background technique
Vertical type multilevel barrel bag pump is multistage, radial subdivision, sectional type housing pump.The suction form of impeller is single suction radial, and is furnished with unit housing.Axial force is born by angular contact ball bearing.When pressure reduction is larger, by balancing drum device balancing axial thrust.Shell only bears inlet pressure, and the length of shell and setting depth depend on the requirement to NPSH cavitation performance.Bearing in bearing housing relies on the Inner eycle automatic lubricating system of internal independence to lubricate.
Existing vertical type multilevel barrel bag pump mainly contains several specifications such as 40,50,80,100,125,150,200.For 40 minimum pump-type B group hydraulic models, its minimum specified applying working condition: flow Q=20m
3/ h, single-stage lift H=35m.When applying working condition is when flow is less, such as Q=6m
3when/h, about single-stage lift H=35m, just lack a kind of suitable vertical barrel pump pump-type to meet this applying working condition.When running into this operating mode, can only replace with 40 pump-type, but 40 pump pumps are in use in the operation of small flow scope always, the efficiency nearly 10 percentage point more on the low side than nominal situation of pump, increases the consumption of the energy, improves user cost in the past.
Summary of the invention
Technical problem to be solved in the utility model is, a kind of small flow vertical type multilevel barrel bag pump is provided, existing vertical type multilevel barrel bag pump architecture basics improves, retaining the type spectrum expanding vertical type multilevel barrel bag pump series pump-type under existing vertical type multilevel barrel bag pump superior structural condition, technical data required for the pump is made to meet the actual demand of low flow rate condition.
The technical solution of the utility model is as follows:
A kind of small flow vertical type multilevel barrel bag pump, comprises import and export section, also comprises the impeller being arranged on axle lower end, it is characterized in that: the inlet size of described import and export section is φ 65 mm, and outlet size is φ 35 mm; The inlet diameter of described impeller is φ 65 mm, and inlet's hub diameter of impeller is φ 50 mm, and the mounting hole diameter of impeller is φ 40; The blade quantity of impeller is six, and the exit width of impeller is 4mm.
The blade of described impeller is cylindrical structure.
Good effect of the present utility model is: the size being imported and exported the import and export bore of section by change, redesign impeller hydraulic model, change the inlet/outlet size of impeller, adjustment impeller intra vane quantity, blade twist form etc., change the performance parameter of impeller, provide a kind of small flow high efficiency vertical type multilevel barrel bag pump, there is minimizing energy consumption, reduce the outstanding feature of user cost.

Fig. 3 is the structure shape schematic diagram of the utility model impeller blade.
Embodiment
The utility model is further illustrated below in conjunction with drawings and Examples.
As shown in Figure 1, the present embodiment comprises imports and exports section 8, and be arranged on the bearing spider 5 of import and export section 8 upper end and be arranged on the balancing drum cover 21 importing and exporting section 8 lower end, balancing drum cover 21 is fixed by seal case 7 and import and export section 8.Seal case 7 upper end is provided with mechanical seal 6.
The present embodiment also comprises and is positioned at motor support base 1 above bearing spider 5 and bearing housing 4, is installed on the bearing cap 2 of bearing housing 4 upper end and is fixed on the rotor part in bearing housing 4 by first ring 26.Described rotor part comprises axle 9, is installed on the upper bearing sleeve 3 of axle 9 upper end portion, is arranged on the bearing 25 on upper bearing sleeve 3 and the adjusting nut 27 for fixing upper bearing sleeve 3.
The neutral position of axle 9 is provided with balancing drum 22, and described balancing drum 22 is fixed on axle 9 by the second ring 23 and the 3rd ring 24.The underpart of axle 9 is provided with impeller 20 and for the Fourth Ring 19 of fixing impeller 20 and fixed cover 18.
The present embodiment also comprises the shell 11 be positioned at below import and export section 8 and the cylindrical tube 10 be installed within shell 11.Cylindrical tube 10 lower end is with discharge cap 12, and discharge cap 12 lower end is provided with middle housing 14, is provided with stator 13 in middle housing 14.Middle housing 14 lower end is provided with suction cover 16, and suction cover 16 lower end is provided with diffusing tube 17.In suction cover 16, lower bearing sleeve 15 is also installed.
The inlet size of described import and export section 8 is φ 65 mm, and outlet size is φ 35 mm; Such a design reduces the specification of supporting pipeline, and then reduce manufacture cost.
As shown in Figure 2, the inlet diameter D of described impeller 20 is φ 65 mm, and the inlet hub diameter D1 of impeller 20 is φ 50 mm, and the mounting hole diameter D2 of impeller 20 is φ 40.The blade quantity of impeller 20 is 6, and the exit width b of impeller 20 is 4mm.
The blade structure of the utility model impeller 20 changes into column type vane structure from original import distortion, outlet column type vane, as shown in Figure 3.
