Abstract
The invention discloses a butt matching low-hump-type bidirectional water-outlet flow channel, belonging to the technical field of hydraulic machinery. The bidirectional water-outlet flow channel is provided with a three-way pipe and two downward gentle curve flow channels; a main pipe opening of the three-way pipe is connected with an outlet of a guide vane; two branch pipe openings of the three-way pipe are respectively connected with inlets of the two downward gentle curve flow channels; the top elevations of the outlet cross sections of the two downward gentle curve flow channels are lower than the lowest water level of an outlet water tank; and the three-way pipe of the bidirectional water-outlet flow channel is manufactured and molded by steel plates, and the two downward gentle curve flow channels are poured and molded by concrete. The flow channel provided by the invention has the advantages of reasonable and simple structure and novel and inventive design, the bidirectional water-outlet flow channel which is formed by the three-way pipe and the two downward gentle curve flow channels is shaped in such a manner that the flow channel curves upwards firstly and then curves gently downwards, the characteristic that the hydraulic loss is obviously less than the open water-outlet flow channel of the low-hump-type water-outlet flow channel is fully utilized, and the efficiency of a pump device is improved greatly; and the core-loosing-type mounting mode of a vertical pump set is maintained for the overhauling of a water pump.
Description
Technical field
The present invention relates to a kind of low-lift pump device, relate in particular to the outlet passage of vertical two-way pump-unit, belong to the hydraulic machinery technical field.
Background technique
Low lift vertical two-way pump-unit is a kind of pump-unit pattern that can way traffic, have advantages such as compact structure, supporting hydraulic structure are few, construction investment province, be widely used at aspects such as riverine regional agricultural drainage and irrigation, water resources allotment, urban flood defence, water environment improvement.
For ease of the installation maintenance of water pump, low lift vertical two-way pump-unit has adopted Drawing-Core water pump structure and open type outlet passage mostly.But the section of linking not between this Drawing-Core water pump diffuser outlet and the open type outlet passage causes the kinetic energy of current to have little time to reclaim and just enters the bigger outlet passage in space, and kinetic energy rejection is bigger.This in addition open type outlet passage the free discharge state occurs through regular meeting under the lower situation of outlet water level, cause water level fluctuation big, produces bigger hydraulic loss.The general lift of two-way pumping plant is lower, and these hydraulic losses have significantly reduced pump assembly efficiency.
Summary of the invention
Purpose of the present invention is exactly at above-mentioned the deficiencies in the prior art, provide a kind of to piecing together low hump formula outlet passage, can improve aspect following two outlet passage hydraulic performance, overcome the lower defective of low lift vertical two-way pump assembly efficiency: (1) makes that water pump diffuser and outlet passage are smooth-going to be connected, and reaches that current turn in order and mild diffusion; (2) the outlet passage outlet is submerged in below the lowest water level, has reduced the outlet hydraulic loss of outlet passage.
The object of the present invention is achieved like this, a kind of to piecing together the low two-way outlet passage of hump formula, it is characterized in that, described two-way outlet passage is connected and composed by three-way pipe and two downward broad warp runners, the person in charge of three-way pipe vertically downward, two arms obliquely, person in charge's mouth of three-way pipe is connected with the stator outlet, two mouths of pipe of three-way pipe are connected with the import of two downward broad warp runners respectively, and the crest level of the outlet section of two downward broad warp runners is lower than the lowest water level in outlet pond.
The three-way pipe of described two-way outlet passage is made moulding by steel plate, and two downward broad warp runners are by the concreting moulding.
The present invention is rational in infrastructure simple, and novel ingenious, using effect is good.Three-way pipe and two two-way outlet passages that downward broad warp runner constitutes, being shaped as of runner is bent upwards broad warp downwards earlier again, the crest level of outlet section is lower than the lowest water level in outlet pond, make full use of low hump formula outlet passage hydraulic loss significantly less than the characteristics of open type outlet passage, improved pump assembly efficiency greatly.But the metal three-way pipe of being made moulding by steel plate is a lifting part, has kept the Drawing-Core mounting type of former vertical pump unit, still can adopt the method for loosing core when making the water pump maintenance, the three-way pipe dismounting is hung, so that the maintenance of water pump.The present invention has very big energy-saving potential, has a extensive future.
Description of drawings
Fig. 1 is facade structures figure of the present invention;
Fig. 2 adopts two-way vertical pump device facade structures schematic representation of the present invention;
Fig. 3 is the two-way vertical pump device facade structures schematic representation of existing open type outlet passage.
Among the figure: 1 three-way pipe, 2 downward broad warp runners, 3 pump shafts, 4 stators.
Embodiment
As shown in Figure 1 and Figure 2, a kind of to piecing together the low two-way outlet passage of hump formula, two-way outlet passage is made of three-way pipe 1 and two downward broad warp runners 2, the person in charge of three-way pipe vertically downward, two arms obliquely, person in charge's mouth of three-way pipe is connected with stator 3 outlets, and two mouths of pipe of three-way pipe are connected with the import of two downward broad warp runners respectively obliquely.The crest level of the outlet section of two downward broad warp runners is lower than the lowest water level in outlet pond.Being shaped as of the outlet passage that three-way pipe 1 and downward broad warp runner constitute is bent upwards broad warp downwards earlier again.
During construction, two downward broad warp runners and pump house become integral body by concreting together, three-way pipe adopts steel plate to make moulding, after performance of over current component of water pump and pump shaft install, with three-way pipe hang in form behind the preformed hole complete to piecing together the low two-way outlet passage of hump formula.
Claims (2)
1. one kind to piecing together the low two-way outlet passage of hump formula, it is characterized in that, described two-way outlet passage is connected and composed by three-way pipe and two downward broad warp runners, the person in charge of three-way pipe vertically downward, two arms obliquely, person in charge's mouth of three-way pipe is connected with the stator outlet, and two mouths of pipe of three-way pipe are connected with the import of two downward broad warp runners respectively, and the crest level of the outlet section of two downward broad warp runners is lower than the lowest water level in outlet pond.
2. a kind ofly it is characterized in that to piecing together the low two-way outlet passage of hump formula the three-way pipe of described two-way outlet passage is made moulding by steel plate according to claim 1 is said, two downward broad warp runners are by the concreting moulding.
