Abstract
The utility model relates to a dredge pump. An inner ring suction pipe is adopted to connect with a flange on a pump housing through a horn mouth, and an outer ring suction pipe is connected with the flange on the pump body through a water suction vertical pipe. The water suction holes of the inner ring suction pipe and the outer ring suction pipe adopt the opening arrangement form of the arithmetic progression along an axial direction, and are arranged from 3 rows to 6 rows along a radical direction. The utility model has the advantages that the range of water suction is enlarged, the dead angle of deposition is eliminated thoroughly, and the application is wide. The utility model is suitable for dredging granular materials with different specific weights and different particle diameters.
Description
The utility model relates to a kind of Under Water Pumps, particularly a kind of pollution discharge pump.
When periodically amorphous industry and urban sewage flowed into plash (pump hole), its SEA LEVEL VARIATION required turn on pump when highest water level between highest water level and lowest water level, and termination of pumping during lowest water level has the dirt deposition when wastewater level rises during termination of pumping.Adopt common vertical sewage pump blowdown, owing to not anti-silt function is blocked up pump, thus the influence operation.For overcoming the problems referred to above, 1992, the vertical anti-silt pollution discharge pump of many suction nozzles has appearred, solved anti-silt problem to a certain extent.But production practices prove that because this pump is 5 suction points, the suction scope is little, and still the bigger deposition dead angle of existence fails thoroughly to solve anti-silt problem, thereby have reduced the actual volume in pump hole, and the generation of the situation of still influential normal operation.
The purpose of this utility model provides a kind of thorough solution deposition dead angle problems of too, enlarges pump hole actual volume, the dicyclo that guarantees the normal operation of the pollution discharge pump vertical anti-silt pollution discharge pump that absorbs water.
The utility model is achieved in that pollution discharge pump is by vertical machine, coupling, outlet pipe, pump housing seal ring, bearing housing, vertical shaft, cylindrical stent, pump case, double-leaf, suction nozzle etc. is formed up and down.The dicyclo vertical anti-silt pollution discharge pump that absorbs water is to adopt by 5 original suction nozzles, change the dicyclo suction pipe into, ring and outer shroud in the dicyclo suction pipe divides, in the ring suction pipe be connected with flange on the pump case by horn mouth, the outer shroud suction pipe is connected with flange on the pump housing by the suction standpipe, on the outer shroud suction pipe annular ledge is housed.Utilize this structure can make the suction expanded range to the end, hole, entire pump hole, thoroughly eliminated the deposition dead angle, the perforate setting type of axial arithmetic series is adopted in the suction hole outside interior ring reaches on the endless tube, and the suction aperture on interior ring and outer shroud is to being arranged as 3-6 rows.Can guarantee suction so evenly, the suction flow velocity is suitable.
The utility model is compared with existing technology, has to have enlarged the suction scope, thoroughly eliminates the characteristics at deposition dead angle.And have and be skillfully constructed, modern design, easy for installation, be the Updated product of pollution discharge pump, its using scope is wide, is applicable to contain different specific weight, and the sewage of different-grain diameter granular material is got rid of.Can be interrupted work, but also continuous operation.
Concrete structure of the present utility model and embodiment are provided by the following drawings;
What accompanying drawing provided is general structure schematic representation of the present utility model.
Below in conjunction with accompanying drawing concrete structure of the present utility model and embodiment are done with further instruction.
See shown in the accompanying drawing: the dicyclo vertical anti-silt pollution discharge pump that absorbs water is made up of vertical machine 1, coupling 2, outlet pipe 3, the pump housing 4, seal ring 5, bearing housing, vertical shaft, cylindrical stent, pump case 11, double-leaf 6, interior endless tube 8 and outer endless tube 9 etc.In ring suction pipe 8 be connected with flange on the pump case 11 by horn mouth, outer shroud suction pipe 9 is connected with flange on the pump housing 4 by the standpipe 7 that absorbs water, and 3-5 annular ledges 10 is housed, as the supporting point of pump on outer shroud suction pipe 9.Utilize this structure can make the suction expanded range, thoroughly eliminated the deposition dead angle to the end, hole, entire pump hole.The perforate setting type of arithmetic series is adopted in suction hole 12 on interior ring suction pipe 8 and outer shroud suction pipe 9 vertically, and 12 radial arrangement are 3-6 rounds in the suction hole of interior ring suction pipe 8 and outer shroud suction pipe 9.Can guarantee suction so evenly, the suction flow velocity is suitable.
