Description
Technical field
The present invention relates to vertical pump, more particularly, relate to a kind of vertical pump and lead whirlpool suction device.
Background technique
In middle-size and small-size vertical pump, in the inlet of vertical pump, usually adopt water inlet water guide cone or water inlet flow channel, for the guiding to current.But no matter be into water water guide cone or water inlet flow channel, all have complex structure, civil engineering and equipment install comparatively difficulty, and construction period is long, and the defect that engineering cost is higher.
Summary of the invention
For the above-mentioned shortcoming existed in prior art, the object of this invention is to provide a kind of vertical pump and lead whirlpool suction device, have several functions, install simple and convenient, cost is lower.
For achieving the above object, the present invention adopts following technological scheme:
This vertical pump is led whirlpool suction device and is connected at below the diffuser of vertical pump, and be connected with impeller shaft, comprise suction body, be located at its inside lead whirlpool blade, guide shaft bearing and locating column, suction body upper end is connected with diffuser and communicates, sidepiece is provided with water intake, guide shaft bearing is located at suction body central upper and is connected with impeller shaft by guide bearing, guide shaft bearing surrounding is provided with plurally leads whirlpool blade, the lower end perforate of guide shaft bearing, locating column is located at suction body lower end, and locating column upper end is fixedly arranged in the lower end perforate of guide shaft bearing.
Described whirlpool blade of leading is spatial warping blade or straight radial blade.
Described guide bearing is ceramic guide bearing.
Described water inlet is also provided with filter screen.
In technique scheme, vertical pump of the present invention is led whirlpool suction device and is located at below the diffuser of vertical pump, and be connected with impeller shaft, comprise suction body, that is located at its inside leads whirlpool blade, guide shaft bearing and locating column, suction body upper end is connected with diffuser and communicates, sidepiece is provided with water intake, guide shaft bearing is located at suction body central upper and is connected with impeller shaft by guide bearing, guide shaft bearing surrounding is provided with plurally leads whirlpool blade, the lower end perforate of guide shaft bearing, locating column is located at suction body lower end, and locating column upper end is fixedly arranged in the lower end perforate of guide shaft bearing.Numerous component are integrated in one by this device, can increase the guiding to current, avoid the generation of whirlpool and loss of energy, reduce vibration and wearing and tearing simultaneously, increase the stability run.Adopt this device can replace water inlet water guide cone or water inlet flow channel completely, civil engineering and equipment are installed more simple, shorten construction period, reduce engineering cost.
Accompanying drawing explanation
Fig. 1 is that whirlpool suction device mounting structure sectional view led by vertical pump of the present invention;
Fig. 2 is the horizontal cross of Fig. 1.
Embodiment
Technological scheme of the present invention is further illustrated below in conjunction with drawings and Examples.
Shown in Fig. 1, Fig. 2, vertical pump of the present invention is led whirlpool suction device and is connected at below the diffuser 1 of vertical pump, and is connected with impeller shaft 2, and the O shape that 3 in Fig. 1,4 is respectively for sealing is enclosed and seal ring, and 5 is impeller.This device mainly comprises in trumpet-shaped suction body 6, be located at its inside lead whirlpool blade 7, guide shaft bearing 8 and locating column 9, suction body 6 upper end is connected with diffuser 1 and communicates, and sidepiece is provided with water intake 10, takes lateral inflow, axially to upper water-out; Guide shaft bearing 8 is located at suction body 6 central upper and is connected with impeller shaft 2 by guide bearing 11, guide shaft bearing 8 surrounding is provided with plurally leads whirlpool blade 7, guide shaft bearing 8 lower end perforate, locating column 9 is located at suction body 6 lower end, and locating column 9 upper end is fixedly arranged in guide shaft bearing 8 lower end perforate, locating column 9 lower end can be fixed on pool bottom, can carry out radial location to the shell of pump (comprising diffuser 1 etc.), increases the stationarity of pump operation.The difference of optic lobe wheel water inlet depth of immersion, described lead whirlpool blade 7 and can adopt spatial warping blade or straight radial blade.Described guide bearing 11 can adopt the ceramic guide bearing or other composite material guide bearing with performances such as excellent resistance to wear, anticorrosive, high temperature resistance, water resistant rise.According to different water quality situations, be also provided with filter screen 12 at described water intake 10 place.
Vertical pump of the present invention is adopted to lead whirlpool suction device, by the function i ntegration of the parts such as suction body 6, filter screen 12, guide shaft bearing 8 in one, and guiding to current can be increased, avoid the generation of whirlpool and loss of energy, reduce vibration and wearing and tearing simultaneously, increase the stability run.There is above-mentioned several functions, not only improve pump performance, but also provide cost savings, comprise manufacture cost and operation expense.In addition, in middle-size and small-size vertical pump, existing water inlet water guide cone or water inlet flow channel can be replaced completely, civil engineering and equipment be installed more simple, shorten construction period, reduce engineering cost.
Those of ordinary skill in the art will be appreciated that, above embodiment is only used to the present invention is described, and be not used as limitation of the invention, as long as in spirit of the present invention, all will drop in Claims scope of the present invention the change of the above embodiment, modification.
