Description of drawings:
Fig. 1 is the adjustable type vortex pump sectional view
Fig. 2 is the adjustable type vortex pump half sectional view
Fig. 3 is impeller size figure.
Among the figure: 1, pump shaft, 2, axle sleeve, 3, mechanical seal, 4, pin, 5, tinsel, 6, bolt, 7, the dividing plate adjusting screw, 8, bulkhead bracket, 9, active clapboard, 10, O-ring seals, 11, O-ring seals, 12, the pump cover support, 13, pump cover adjusting screw, 14, pump cover, 15, tinsel, 16, impeller, 17, pump cover cover, 18, bolt, 19, the pump housing, 20, pump seat, 21, intake pipe, 22, outlet pipe, 23, blade.
Embodiment:
Consult accompanying drawing (1-3).In Fig. 1, pump shaft 1 is connected with axle sleeve 2 by screw thread, axle sleeve 2 is connected with impeller 16 by pin 4, the endoporus of the outer rim of axle sleeve 2 and impeller 16 is to be slidingly matched, and between the axle sleeve 2 and the pump housing 19 mechanical seal 3 is housed, and bulkhead bracket 8 is housed on pump seat 20, in the hole of the other end of bulkhead bracket 8, be installed with dividing plate adjusting screw 7, dividing plate adjusting screw 7 fuses with active clapboard 9, during nut on turning dividing plate adjusting screw 7, can regulate the gap between active clapboard 9 and the impeller 16.Outer rim at pump cover 14 is equipped with pump cover cover 17, and be slidingly matched with it, O-ring seals 11 is equipped with in the centre, pump cover adjusting screw 13 is housed on the pump cover 14, and the other end of pump cover adjusting screw 13 is packed in the hole of pump cover support 12, and two of pump cover support 12 is fixed on the pump seat 20 with bolt 18, during nut on turning pump cover adjusting screw 13, pump cover 14 can overlap in 17 at pump cover and slide, and to adjust the gap between impeller 16 and the pump cover 14, between the pump cover cover 17 and the pump housing 19 O RunddichtringO 10 is housed.If the pump housing 19, pump cover 14, pump cover cover 17 are made of plastic, stud with tinsel 5 on the surface of its pump housing 19, stud with tinsel 15 on the surface of pump cover 14, to increase its wear resistance.The pump housing 19, pump cover 14, pump cover cover 17 also can be made with metal.The external diameter of pump cover 14 equates with the external diameter of impeller 16.
During work, pump shaft 1 is by 16 rotations of axle sleeve 2 impeller, in the runner of liquid in intake pipe 21 enters the pump housing 19, after the blade 23 of impeller 16 quickens again and again, produce vortex and centrifugal power, in runner, form the zone of high pressure, because active clapboard 9 keeps very little gap with the outer rim of impeller 16, every having lived zone of high pressure flow direction water intake, and flow out, form very high working pressure from outlet pipe 22.
When wearing and tearing when excessive in the impeller 16 and the gap of active clapboard 9, turn the nut on the dividing plate adjusting screw 7, gap between active clapboard 9 and the impeller 16 is turned down, when wearing and tearing when excessive in the impeller 16 and the gap of pump cover 14, turn the nut on the pump cover adjusting screw 13, the gap between pump cover 14 and the impeller 16 is turned down.
