Summary of the invention
The utility model proposes a kind of silo infusion pump that is provided with the inlet guide vane body device, purpose is by designed inlet guide vane body device, the water outlet of through-flow pump water intake and water inlet flow channel is not directly joined, to cut off the continuity that pump housing impeller inlet refluxes, improve the water inlet condition of silo infusion pump, reduce headloss, reduce depth of immersion, and promote Security and the stability of pump shaft operation.
Technical solution of the present utility model
The through-flow pump that the utility model is alleged, its power engine and actuating unit thereof are arranged in the vertical shaft that completely cuts off with current; Through-flow pump is positioned under the inspection-pit again simultaneously between water inlet flow channel peace straight tube outlet passage; Be provided with into water bulkhead gate between described water inlet pool and the water inlet flow channel; Be provided with export gate, outlet bulkhead gate between straight pipe outlet passage and the water outlet pool successively.
The inlet guide vane body device that the utility model is alleged is arranged at the inlet end place of described through-flow pump body.The single piece that this device mainly is made of inlet guide vane urceolus, inlet guide vane inner core, stator and flange plate, described inlet guide vane urceolus is hollow round table-like, and the bigger diameter end of its round platform and water inlet flow channel outlet port join; The miner diameter end of its round platform is connected with flange plate with the inlet end of through-flow pump body; Described stator is arranged in the inlet guide vane body device.
Described stator is laminar body, is provided with 4～8, and centered by pump shaft, etc. the orientation be laid in the inlet guide vane device.
The angle of throat that described inlet guide vane urceolus is hollow round platform is 4 °～8 °.
Described stator is along water (flow) direction casting or be welded between inlet guide vane urceolus and the inlet guide vane inner core.
Described inlet guide vane inner core is enclosed within outside the preceding guide bearing of through-flow pump shaft, is positioned at the center portion of inlet guide vane body device.
Each component parts of described inlet guide vane body device is metal material.
The beneficial effects of the utility model
The inlet guide vane body device that the utility model is set can suppress through-flow pump impeller inlet hoop flow velocity effectively, improves the water inlet condition of water pump; Under low flow rate condition, guide vane can cut off the continuity that impeller inlet refluxes, and suppresses the generation expansion that refluxes, reduce the headloss of through-flow pump, reduce the requirement to depth of immersion, can corresponding reduction pump house cutting depth, reduce the civil engineering workload, the unit of being more convenient for is installed and maintenance; And the inlet guide vane body device is set in guide bearing before the pump housing, can reduce the throw of through-flow pump shaft; Safety and the stability of pump shaft operation have been improved.
Description of drawings
Accompanying drawing 1 is the plan structure schematic representation of the utility model integral body;
Accompanying drawing 2 is the structural representation of the alleged inlet guide vane body device of the utility model.
Embodiment
As shown in Figure 1,
The utility model part same as the prior art is that the power engine 11 of through-flow pump body 1 and pto 12 thereof are arranged in the vertical shaft 2 that completely cuts off with current; And the body of pump is between water inlet flow channel 3 peaceful straight tube outlet passages 4.Be provided with into water bulkhead gate 31 between water inlet pool 5 and the water inlet flow channel 3; Be provided with export gate 41, outlet bulkhead gate 42 between straight pipe outlet passage 4 and the water outlet pool 7 successively; The through-flow pump body is positioned at the below of inspection-pit 8 simultaneously again.
The utility model innovation part unlike the prior art is that the inlet end place of through-flow pump body is provided with inlet guide vane body device 9.
It is and for example shown in Figure 2,
The single piece that inlet guide vane body device of the present utility model mainly is made of inlet guide vane urceolus 91, inlet guide vane inner core 93, stator 92 and flange plate 94.Described inlet guide vane inner core is enclosed within outside the preceding guide bearing 14 of through-flow pump shaft 13.
The round platform angle of throat of the given inlet guide vane urceolus of embodiment is 5 ° among the figure; Stator is 4.
Sketch working procedure of the present utility model below in conjunction with accompanying drawing:
