For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of irrigation and water conservancy irrigation pumping station pumping system, this irrigation and water conservancy irrigation pumping station pumping system is arranged between river and water channel, and its innovative point is: comprise between discharge bay, control and water plug;
Comprise the upper and lower between described control, the bottom of lower floor is under river level, and described discharge bay is arranged between control and between water channel, and the bottom of discharge bay is higher than lower level floor between control, and described upper strata is provided with distribution facility;
Described water plug comprises water inlet pipe, suction pump and outlet pipe, described suction pump is arranged on lower level floor between control, described suction pump is provided with water inlet and delivery port, water inlet is near side, river, delivery port is near discharge bay side, water inlet and delivery port all tilt upward setting, the angle of water inlet and horizontal plane is between 145 ° ~ 150 °, described water inlet pipe is connected with water inlet, water inlet pipe comprises one-level water inlet pipe and secondary water inlet pipe, secondary water inlet pipe transverse direction is connected with water inlet and end to extend between control outside wall, one-level water inlet pipe is connected with secondary water inlet pipe is in 90 °, this one-level water inlet pipe is perpendicular to the river water surface, described outlet pipe is connected with delivery port, and outlet pipe and delivery port form a straight line tilted upward, the most significant end of this outlet pipe extends to the bottom of discharge bay, O RunddichtringO is provided with between the pump shaft of described suction pump and axle sleeve.
The utility model has the advantage of: suction pump is arranged on below water level by the utility model device, reduce water inlet and inhale journey, thus reduce the air entering water pipe, shorten emptying time;
The water inlet of suction pump is changed into and slightly upwarps 12 to 15 degree, and be form 145 to 150 between center of circle water inlet and delivery port to spend angle with suction pump, can in pipeline natural water, can make to deposit a certain amount of water for a long time in suction pump spiral case, that impeller High Rotation Speed produces centrifugal force and thrust to water thus produces vacuum voluntarily, without the need to arranging bottom valve in suction pump start running, thus elimination water resistance, also pour water without the need to repeating;
Water inlet pipe is vertically arranged and floods the water surface, ensure enough depth of immersions, thus avoid the generation of whirlpool, to ensure that when low water stage also without the need to adapter road again;
Due to outlet pipe and delivery port on the same line, resistance coefficient is reduced to minimum, thus seen the bottom outlet pipe local power loss;
The top of outlet pipe is arranged on bottom discharge bay, changes closed delivery water outlet into, and water outlet elevation reduces, and consume energy little, and water yield increases greatly;
Be provided with O RunddichtringO between the pump shaft of suction pump and axle sleeve and solve gas leak phenomenon, indirectly reduce power consumption; Distribution facility is power distribution cabinet dress star delta reduced-voltage starting mode, and add simultaneously and join phase shortage and overload protection, go back the combination of relay service time, auxiliary reclay and AC relay, this structure is simple, and operate very safety and stability, fault rate is extremely low.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model device irrigation and water conservancy irrigation pumping station pumping system.
Detailed description of the invention
A kind of irrigation and water conservancy irrigation pumping station pumping system as shown in Figure 1, this irrigation and water conservancy irrigation pumping station pumping system is arranged between river 1 and water channel 2, comprise discharge bay 4, control between 3 and water plug.
Between control, 3 comprise the upper and lower, and the bottom of lower floor is under river 1 water level, and discharge bay 4 is arranged between control between 3 and water channel 2, and the bottom of discharge bay 4 is higher than 3 lower level floor between control, and upper strata is provided with distribution facility.
Water plug comprises water inlet pipe 8, suction pump 5 and outlet pipe 9, suction pump 5 is arranged on 3 lower level floor between control, suction pump 5 is provided with water inlet 6 and delivery port 7, water inlet 6 is near side, river 1, delivery port 7 is near discharge bay 4 side, water inlet 6 and delivery port 7 all tilt upward setting, the angle of water inlet 6 and horizontal plane is between 145 ° ~ 150 °, water inlet pipe 8 is connected with water inlet 6, water inlet pipe 8 comprises one-level water inlet pipe and secondary water inlet pipe, secondary water inlet pipe transverse direction is connected with water inlet 6 and end to extend between control outside 3 walls, one-level water inlet pipe is connected with secondary water inlet pipe is in 90 °, this one-level water inlet pipe 8 is perpendicular to the river water surface, outlet pipe 9 is connected with delivery port 7, and outlet pipe 9 and delivery port 7 form a straight line tilted upward, the most significant end of this outlet pipe 9 extends to the bottom of discharge bay,
