Description
Technical field
The utility model relates to a kind of diving reflux pump, being specifically related to a kind of air guide sleeve adopts mould once compressing, air guide sleeve boundary dimension can be guaranteed, and profile is not easy distortion, the gap coordinating with impeller is balanced consistent, during whole pump operation, the diving reflux pump of the guaranteed integrated air guide sleeve in gap.
Background technique
Diving reflux pump is the special device that sewage treatment works's secondary mixed solution adds stream, denitrification denitrogenation, is mainly used in liquid backflow, circulation between two ponds, is specially adapted to sewage medium, large flow, low lift, small-power; Between two pool walls, perforation is installed, very convenient, and can be used for needing in the water supply and sewage work of ground the place of micro-lift, large flow.Diving reflux pump air guide sleeve Main Function is stabilizing solution stream, the flow of pump, lift and pipe-line system stable had to important function, Some Domestic producer is mainly to adopt welding manner to the production method of air guide sleeve at present, the air guide sleeve of welding mainly contains the defect of the following aspects: the air guide sleeve of (1), welding is yielding, and key dimension is not easy to guarantee; (2), material and cost of labor increase, and is unfavorable for saving cost of production; (3), install with main frame and pipeline after, liquid stream is unstable, flow, the headloss of pump are larger.
Model utility content
For the problems referred to above, main purpose of the present utility model is to provide a kind of air guide sleeve to adopt mould once compressing, air guide sleeve boundary dimension can be guaranteed, and profile is not easy distortion, the gap coordinating with impeller is balanced consistent, during whole pump operation, the diving reflux pump of the guaranteed integrated air guide sleeve in gap.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of diving reflux pump of integrated air guide sleeve, described diving reflux pump comprises lifting part, motor component, front-end bearing pedestal, integrated type air guide sleeve, stiffening plate, coupling plate, wall-passing pipe, grade bar, impeller, it is characterized in that: described diving reflux pump comprises and also comprises integrated type air guide sleeve, described coupling plate and wall-passing pipe, the wedge shape inclined-plane of grade bar coordinates, the axle of motor component is arranged in the pump housing through front-end bearing pedestal, the front end of described axle is provided with described impeller, Zhou He is provided with mechanical seal between grease chamber, integrated type air guide sleeve is by the compressing rear and coupling of mould, stiffening plate welding, and by clamping bolt together with main frame anchor ear, grade bar and wall-passing pipe are welded as a whole, formed the wall-passing pipe assembly of band coupling gradient, during installation, wall-passing pipe is embedded in needs to install between two pool walls of diving reflux pump.
In preferred embodiment of the present utility model: the coupling gradient of described coupling plate is consistent with the coupling gradient of wall-passing pipe assembly grade bar.
Positive progressive effect of the present utility model is: the utility model (1), saving material, reduce production costs; (2), improve pump operation reliability, guarantee technical data required for the pump.
Accompanying drawing explanation
Fig. 1 is general structure schematic diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, provide the utility model preferred embodiment, to describe the technical solution of the utility model in detail.
Fig. 1 is general structure schematic diagram of the present utility model.As shown in Figure 1: the diving reflux pump of the integrated air guide sleeve that the utility model provides, comprise lifting part 1, motor component 2, front-end bearing pedestal 3, integrated type air guide sleeve 4, stiffening plate 5, coupling plate 6, wall-passing pipe 7, grade bar 8, impeller 9, by coupling plate 6, coordinate with the wedge shape inclined-plane of wall-passing pipe 7, grade bar 8.
The axle 10 of motor component 2 is arranged in the pump housing through front-end bearing pedestal 3, the front end of described axle 10 is provided with described impeller 9, between Zhou10He grease chamber 12, be provided with mechanical seal 11, integrated type air guide sleeve 4 is by the compressing rear and coupling plate 6 of mould, stiffening plate 5 welding, and by clamping bolt together with main frame anchor ear, grade bar 8 is welded as a whole with wall-passing pipe 7, formed the wall-passing pipe assembly of band coupling gradient, during installation, wall-passing pipe 7 is embedded between two pool walls of diving reflux pump, diving reflux pump is along guide rod downslide under water, coupling gradient due to coupling plate 6 on integrated type air guide sleeve, consistent with the coupling gradient of wall-passing pipe assembly grade bar 8, therefore can guarantee that Beng center is consistent with wall-passing pipe assembly center, thereby can guarantee the normal operation of pump.
Diving reflux pump adopts sweepback type propeller impeller, according to the mode of operation special design of low lift, large flow, submersible motor drives impeller rotation during work, the kinetic energy that rotary blade produces makes a medium (clear water or sewage) in pond be sent in another pond by wall-passing pipe, thereby realize the function of carrying all kinds of sewage media under various different operating modes, between two pool walls, connect and install, very convenient.
In implementation process of the present utility model, the air guide sleeve of integrated air guide sleeve 4 diving reflux pumps does not adopt welding manner, but adopt mould once compressing, owing to being that mould is compressing, therefore air guide sleeve boundary dimension can be guaranteed, and profile is not easy distortion, the gap coordinating with impeller is balanced consistent, during whole pump operation, because gap is guaranteed, fluid is stressed more balanced, stream is breathed heavily in difficult formation, thereby avoided the oscillation phenomenon of pump, the flow and lift of pump also can meet the requirements simultaneously, in addition owing to being die forming, during batch production, can significantly reduce raw-material loss, cost of production and cost of labor have been reduced.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications; these changes and improvements all fall within the scope of claimed the utility model, and the claimed scope of the utility model is defined by appending claims and equivalent thereof.
