Abstract
A three-side water outlet rear-mounted shaft tubular pump device relates to the technical field of shaft tubular pump devices and comprises a water inlet flowing passage and a water outlet flowing passage. A water pump is disposed between the water inlet flowing passage and the water outlet flowing passage, a shaft is disposed inside the water outlet flowing passage, two-side water outlet passages are arranged among the shaft and two lateral walls of the water outlet flowing passage, a bottom water outlet passage is arranged between the shaft and the lower bottom of the water outlet flowing passage, and a supporting separating pier is arranged between the shaft and the bottom of the water outlet flowing passage. Due to increasing area of water outlet section, the three-side water outlet rear-mounted shaft tubular pump device obviously reduces flow speed, is favorable for recycling kinetic energy, reduces hydraulic loss, and increases efficiency of a pump station whiling reducing engineering investment.
Description
Technical field
The utility model relates to a kind of technical field of shaft tubular pump.
Background technique
In the pumping plant of hydraulic engineering is built, the pumping plant of low lift can adopt rearmounted vertical shaft type through-flow pump, wherein the water pump horizontal axis is arranged, runner is straight, in the hope of reducing the hydraulic loss of runner, though this design can reach the purpose of drawing water, but because the structural feature of vertical shaft, water outlet can only flow to water outlet pool from the left and right sides of vertical shaft, the water outlet cross-sectional area is less, and exit of pump kinetic energy is difficult to reclaim, if increase the water outlet cross-sectional area then need to drop into than the multiple-project fund, cause unnecessary manpower, material resources, land wastage, therefore existing rearmounted shaft tubular pump can not given full play to its effect.
The model utility content
The purpose of this utility model is: provide a kind of vertical shaft type tubular pump efficient of giving full play to, the rearmounted shaft tubular pump of the three side water outlets that economize on resources.
The purpose of this utility model is achieved in that the rearmounted shaft tubular pump of three side water outlets, comprise water inlet flow channel and outlet passage, between described water inlet flow channel and the outlet passage water pump is set, in the described outlet passage vertical shaft is set, between two sidewalls of described vertical shaft and described outlet passage the both sides exhalant canal is set, the bottom exhalant canal is set between the going to the bottom of described vertical shaft and described outlet passage, the support dividing pier is set at the end of described vertical shaft and described outlet passage.
The utility model and the common rearmounted vertical shaft type tubular pump comparison of both sides water outlet have the following advantages:
(1) because the increase of water outlet cross-sectional area obviously reduces flow velocity, helps recover kinetic energy, reduces hydraulic loss;
(2) when construction investment reduces, improved the efficient of pumping plant.
For ease of the layout of gear-box and motor, the horizontal cross sectional geometry of described vertical shaft is the streamline oblateness.
For reducing the water inlet flow channel loss, the horizontal cross sectional geometry of described support dividing pier is the streamline oblateness.
Description of drawings
Fig. 1 is a kind of structural representation of the present utility model.
Fig. 2 is that the A-A of Fig. 1 is to generalized section.
Fig. 3 is that the B-B of Fig. 2 is to generalized section.
Wherein: 1-water inlet flow channel, 2-water pump, 3-vertical shaft, 4-both sides exhalant canal, 5-bottom exhalant canal, 6-support dividing pier, 7-outlet passage.
Embodiment
As shown in Figure 1, 2, 3, the rearmounted shaft tubular pump of three side water outlets, comprise water inlet flow channel 1 and outlet passage 7, between water inlet flow channel 1 and the outlet passage 7 water pump 2 is set, vertical shaft 3 is set in the outlet passage 7, between two sidewalls of vertical shaft 3 and outlet passage 7 both sides exhalant canal 4 is set, bottom exhalant canal 5 is set between the going to the bottom of vertical shaft 3 and outlet passage 7, support dividing pier 6 is set at the end of vertical shaft 3 and outlet passage 7.
The horizontal cross sectional geometry of vertical shaft 3 is the streamline oblateness.
The horizontal cross sectional geometry that supports dividing pier 6 is the streamline oblateness.
Claims (3)
1. the rearmounted shaft tubular pump of three side water outlets, comprise water inlet flow channel and outlet passage, between described water inlet flow channel and the outlet passage water pump is set, in the described outlet passage vertical shaft is set, it is characterized in that: between two sidewalls of described vertical shaft and described outlet passage the both sides exhalant canal is set, the bottom exhalant canal is set between the going to the bottom of described vertical shaft and described outlet passage, the support dividing pier is set at the end of described vertical shaft and described outlet passage.
