Embodiment
As depicted in figs. 1 and 2, a kind of self-sucking non-blockage sewage pump, comprise the pump housing 1, rotating shaft 2, impeller 5, pump cover 22 and suspension 23, the pump housing 1 comprises grease chamber 3, spiral case 4, gas-liquid separation chamber 6, intake pipe 7, liquid storage room 8 and front shroud 16, pump cover 22 is arranged at spiral case 4 left surfaces, suspension 23 is fixed on the pump housing 1 left end, rotating shaft 2 one end are connected with impeller 5, the other end runs through pump cover 22, grease chamber 3 is connected with suspension 23 and with the bearing 9 of suspension 23 left ends, impeller 5 is arranged at spiral case 4 inside, spiral case 4 lower end right flanks are provided with return port 10, return port 10 is by one-way water inlet valve 11 and liquid storage room 8 UNICOMs, the outlet 12 of spiral case 4 upper ends is arranged in gas-liquid separation chamber 6, gas-liquid separation chamber 6 upper ends are provided with water outlet 13 straight up, intake pipe 7 one end are connected with spiral case 4 water inlets, liquid storage room 8 is provided with shower 14, shower 14 one end are inner at intake pipe, the water outlet of shower 14 is along impeller 5 central axis directions and be right against impeller 5, on shower 14, be provided with control valve 15.Impeller 5 comprises back blade 21, blade 19 and back shroud 17, and front shroud 16 is secured by bolts on spiral case 4 inwalls.
Intake pipe 7 of the present invention is connected with outside sewage pipe, when the present invention starts, intake pipe 7 internal memories leave air, impeller 5 rotations are rotated in rotating shaft 2, rotation by impeller 5 produces negative pressure, air in intake pipe 7 can be because pressure difference enters in impeller 5, control valve 15 is opened simultaneously, shower 14 sprays into the liquid in liquid storage room 8 in impeller 5, rotation by impeller 5 mixes gas and liquid, make impeller 5 inlets produce larger negative pressure, the dependence of the self-priming performance of having avoided common self-suction sewage pump to separation tongue gap, shorten self-priming time simultaneously, gas-liquid mixture enters in spiral case 4 from impeller 5, then from the outlet 12 of spiral case 4 upper ends, enter gas-liquid separation chamber 6, the interior liquid of gas-liquid separation chamber 6 and air by self gravitation poor carry out separated, gas can be discharged by water outlet 13, liquid can flow back in spiral case 4, and enter in liquid storage room 8 by return port 10 and one-way water inlet valve 11, so circulation, until the air in intake pipe 7 is drained, now entering whole in impeller 5 is liquid, control valve 15 is closed, shower 14 stops water spray, reduced the eddy current between pump inner flow passage, reduced the eddy current loss in flowing, effectively mentioned the efficiency of pump, by impeller 5 High Rotation Speed ceaselessly, the sewage that enters intake pipe 7 all can flow out by water outlet 13.
