Abstract
The utility model relates to a water inlet cone for a mixing flow pump of large-scale vertical type, which is characterized in that the water inlet cone is a corn shape and is arranged under the water inlet hole of the pump, sharing the same axis with the water inlet hole of the pump; a small platform of the water inlet cone faces the water inlet hole; a flow separation plate is vertically arranged on the cone body of the water inlet cone; the water inlet cone is fixedly connected with the flow separation plate. Compared with the prior art, the utility model changes inlet water flow mode of the pump, enables the water flow to flow into inner impeller of the water inlet pump in an ideal flow direction and having no vortex, reduces water loss before flowing into the pump, has simple structure and is easy to be used.
Description
Technical field
The utility model relates to a kind of water inlet flow channel of large-scale vertical mixed flow pump, and concrete a kind of large-scale vertical mixed flow pump water inlet that enters in the pump that can make water not have whirlpool that relates to is bored.
Background technique
Current enter in the pump generally speaking, and by the rotation along with impeller in the pump, the current at water inlet loudspeaker place can form whirlpool, and whirlpool can reduce the liquid level of current, influences the efficient of drawing water of pump, and pump generally is furnished with special water inlet flow channel for this reason.
General large-scale vertical mixed flow pump water inlet flow channel has various ways, but provides scheme and concrete size requirement by pump manufacturer man mostly, is cast with concrete by user's civil engineering to form again.The error of the shape and size that cause thus can directly cause using effect bad.
As the described a kind of mixed flow pump that is used for two liquid of Chinese patent 92112483.X, it comprises the centrifugal pump of a housing and level, has a guide plate in the described housing, and guide plate is between the downside of import and impeller, guide plate is an annular, and guide plate also comprises the ring baffle of a substantial level.Its baffle plate of this mixed flow pump is arranged on water intake in the housing, because the water intake size is fixing, the water conservancy diversion effect of guide plate is not remarkable, and geomery all is subjected to the water intake size restrictions.
The model utility content
Technical problem to be solved in the utility model is, overcomes the shortcoming of conventional water inlet flow channel, provides a kind of and guarantees that the import flow energy loss of pump is little, makes simply, and is easy for installation, the large-scale vertical mixed flow pump water inlet awl that can use for a long time.
In order to address the above problem, the technical solution of the utility model is such:
Large-scale vertical mixed flow pump water inlet awl, comprise into water awl and flow distribution plate two-part, it is characterized in that, described water inlet awl is cone shape, the water inlet awl is arranged on the water intake below of pump, and the water inlet awl is same axis with the water intake of pump, and the little table top of water inlet awl is towards water intake, the cone of water inlet awl is provided with the flow distribution plate of vertical direction, and water inlet awl and flow distribution plate are for fixedlying connected.
Described water inlet awl is the revolution cone, and the big table top of water inlet awl and little table top are circular, and the part that connects big table top and little table top is the turning circle arc surface, and described arc size is determined by pump duty, water velocity and water conservancy diversion direction.
Described flow distribution plate is dull and stereotyped, is connected by welding manner with cone.
Described water inlet awl inside is provided with pre-buried hook, can easily the water inlet awl be fixed on the concrete foundation.
Described water inlet awl top is provided with lifting eye, can easily the water inlet awl be got up convenient the installation.
Beneficial effect, compared with prior art, the utility model has improved the import flow-shape of pump, can make current as much as possible according to enter pump in the impeller of inviscid flow to no whirlpool, has reduced the hydraulic loss before flowing in the pump, and is simple in structure, easy to use.

Embodiment
For technological means, creation characteristic that the utility model is realized, reach purpose and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.
Referring to Fig. 1, Fig. 2, the utility model large-scale vertical mixed flow pump water inlet awl, comprise cone 1 and flow distribution plate 2, cone 1 is a solid of rotation, upper table surface 11 is little table top, following table 12 is big table top, the center of last following table 11,12 is on same axis 13, the camber line of following table 11,12 is revolution camber line 14 in the connection, and gyration center is an axis 13, also has a lifting eye 15 on the described cone 1, can easily the water inlet awl be got up, the convenient installation, cone 1 inside has pre-buried hook 16, can easily the water inlet awl be fixed on the concrete foundation during installation.Flow distribution plate 2 is a vertical direction, and flow distribution plate 2 welds together with cone 1, and axis 3 is passed on plane, flow distribution plate 2 place, and flow distribution plate 2 is highly identical with cone 1, and whirlpool can be shunted and eliminate to flow distribution plate 2.
Water inlet awl cone 1 is by the cast steel manufacturing, and flow distribution plate 2 is by the steel plate manufacturing, and certainly according to water quality and other requirements, cone 1 can be made by other metals, as stainless steel material.
Referring to Fig. 3, during assembling, cone 1 is winched on the concrete foundation, the dead in line of the axis 13 and the pump housing, pre-buried hook 16 stretches in the concrete, and casting back cone 1 promptly is fixed on promptly finishes installation on the concrete foundation.
Compared with prior art, the utility model has improved the import flow-shape of pump, can make current as much as possible according to enter pump in the impeller of inviscid flow to no whirlpool, has reduced the hydraulic loss before flowing in the pump, and is simple in structure, easy to use.
More than show and described basic principle of the present utility model, major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that describes in the foregoing description and the specification just illustrates principle of the present utility model; the utility model also has various changes and modifications under the prerequisite that does not break away from the utility model spirit and scope, and these changes and improvements all fall in claimed the utility model scope.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
