The utility model discloses a use method as follows:
when the impeller adopts blowdown impeller 801, the fixed plate that has water seal ring 811 is then adopted to the functional block, and the fixed plate 810 center that has water seal ring 811 is complete hollow state, do not have the cutting strip 914 that can cut, at this moment along with blowdown impeller 801 rotates, the rivers that originally are full of in the pump body 1 then can be stirred, thereby realize the pressure boost, external rivers then loops through water mouth 6, fixed plate 810 hole, the head 805 of intaking constantly enters into the pump body 1, finally flow out from water connectors 3 under the pressure boost effect of blowdown impeller 801, accomplish the blowdown work.
In the practical use process of the sewage impeller 801, in order to meet the assembly requirement of the cutting impeller 903 and the cutting ring 912, the water inlet hole 4 needs to be set to be of a large caliber, under the condition, a larger gap must exist between the outer wall of the water inlet head 805 of the sewage impeller 801 and the inner wall of the water inlet hole 4, and the water sealing ring 811 can effectively fill the gap between the outer wall of the water inlet head 805 and the inner wall of the water inlet hole 4, so that the situation that when the gap between the outer wall of the water inlet head 805 and the inner wall of the water inlet hole 4 is too large, a part of water flow in the pump body 1 flows back to the outside through the gap between the outer wall of the water inlet head 805 and the inner wall of the water inlet hole 4 when the sewage impeller 801 drives the water flow in the pump body 1 to flow back towards the water outlet joint 3 is avoided, the effect of preventing backflow is achieved, and accidents caused by backflow are avoided.
Fixed plate 810 upper surface is equipped with one and is annular seal groove 813, seal groove 813 encloses including closing with sealing ring 811, seal groove 813 is relative with 1 lower surface of the pump body, be equipped with in the seal groove 813 rather than assorted sealing washer 814, the existence of sealing washer 814 can effectively improve the leakproofness between fixed plate 810 upper surface and the 1 lower surface of the pump body, thereby effectively guarantee the sealed effect of sealing ring 811 outer lane, effectively improve the water effect of sealing between sealing ring 811 the 4 inner walls of head 805 outer walls of intaking and inlet opening, avoid the rivers refluence in the water pump to the external condition in the at utmost.
Except the normal blowdown work, when still needing to cut debris in the rivers, can dismantle blowdown impeller 801 from connector 7 of motor shaft 201 lower extreme, because between connector 7 and the blowdown impeller 801 accomplish both to fix through the cooperation of first flat key 809 and first flat key groove 808, consequently can dismantle blowdown impeller 801 fast, and be equipped with a plurality of first perforation 812 coaxial with screw 10 on the fixed plate 810, when needing to fix fixed plate 810, only need upwards pass first perforation 812 and spiro union in screw 10 with the screw, make the head of screw press on the fixed plate lower surface simultaneously can, the dismouting of fixed plate 810 is convenient for to this kind of fixed mode, thereby do benefit to the quick switch-over of water pump function, along with the dismantlement of blowdown impeller 801 and fixed plate 810, only need to change new cutting impeller 903 and cutting ring 912, just can make the water pump have the cutting function.
When the impeller adopts the cutting impeller 903, the functional component is the cutting ring 912, and as the cutting impeller 903 rotates, the cutting impeller 903 can pressurize water flow filled in the pump body 1, at the moment, external water flow can sequentially pass through the water through port 6, a gap between the adjacent cutting strips 914 and the water inlet 4 into the pump body and is finally discharged from the water outlet connector 3 to complete sewage discharge work, and when water flow passes through the gap between the adjacent cutting strips 914, sundries mixed in the water flow can be in contact with the cutting strips 914, the surface of the cutting strips 914 is provided with a plurality of cutting teeth 915 which are uniformly distributed, the sundries mixed in the water flow can be effectively cut by the cutting teeth 915, the cutting effect is more obvious under the pushing of water pressure of the water flow, the sundries can be effectively cut up, so that the condition that the impeller is blocked due to the non-cutting condition of large sundries can be effectively avoided, and the normal operation of the sewage discharge work is ensured.
Because the connecting shaft sleeve 901 and the connecting head 7 are connected and fixed through the matching of the second flat key 907 and the second flat key slot 906, the connecting shaft sleeve 901 and the connecting head 7 can be quickly detached, and the connecting pipe 902 and the hub 904 of the cutting impeller 903 are connected and fixed through the matching of the third flat key 910 and the third flat key slot 909, so that the connecting pipe 902 and the hub 904 can be quickly detached, and the lower surface of the cutting ring 912 is provided with a plurality of second through holes 916 coaxial with the screw holes 10, when the cutting ring 912 needs to be fixed, a screw only needs to pass through the second through holes 916 upwards and is screwed in the screw holes 10, and meanwhile, the head of the screw presses on the lower surface of the cutting ring 912, so that the fixing mode is convenient for the disassembly and assembly of the cutting ring 912, is beneficial to the quick switching of the functions of a water pump, and can quickly switch the cutting function of the water pump to the ordinary supercharging and blowdown function.
To sum up, can know, the utility model discloses the function of water pump is changed fast to the mode that impeller subassembly and functional module were changed to the accessible, can make the change of water pump between ordinary pressure boost blowdown function and cutting function, when needing different functions, only need to change impeller subassembly and functional module can, need not to change whole ordinary water pump or cutting pump, effectively reduce the replacement cost to effectively reduce the blowdown cost, make the water pump can adapt to different blowdown environment under low-cost state.
