Abstract
Provided is a water inlet suction section part of a vertical type pump. A body comprises a shell body and a hub. Vanes are arranged between the shell body and the hub. The shell body and the hub of the part are connected through the vanes. Meanwhile, the vanes support the shell body and the hub, and the vanes, the shell body and the hub form eight spaces with the same size. The spaces are pass spaces of conveyed media. The vanes comprise two kinds, namely first vanes and second vanes. The two kinds of vanes are evenly distributed on the hub and the shell body at intervals. Impellers are arranged at intervals evenly in the periphery direction, media entering the part are separated, during a runoff process in the spaces, the non-axial rotating speed of the media is reduced as soon as possible in a gradually-decrescent overflow space, the space is saved, axial length is small, radial length is large, the suction section part is used as a water inlet section of a pump, good streamline design is arranged inside, and flowing of the conveyed media can be well achieved.
Description
Technical field:
The present invention relates to a kind of parts for vertical pump, particularly relate to a kind of water inlet suction casing parts of vertical pump.
Background technique:
Current, along with the develop rapidly of name of the country economy, China is faced with huge energy demand and severe Energy situation, for this universal machine of pump, improves its performance, has great importance to energy efficient.Make designed function admirable, only have the impeller of function admirable to be inadequate, must have the component matched with it, entirety just can reach best effect.Research shows, impeller blade suction surface is minimum near entry zone pressure, occurs negative value sometimes, and this region likely cavitation corrosion will occur.Under certain relative case, control its inlet pressure by control blade or impeller inlet velocity of medium, thus improve cavitation erosion, cavitation phenomenon.The fluid entering impeller has rotation phenomenon simultaneously, does not flow by the situation of anticipation at once, thus bring energy consumption when this phenomenon causes fluid to enter blade.Inlet whirl regulation technology is applied to wind energy conversion system regulating working conditions at the beginning of the fifties in last century, achieves good regulating effect.The later stage eighties in last century, domestic scholars also from then on direction set about research, for a long time, there has been certain breakthrough the racemization aspect for pump impeller inlet fluid.It is little that spatial guide blade has radial dimension, the advantage such as can to coordinate, just becoming a kind of common water distributor with the impeller such as mixed flow pump or Pump for well streamline smoothness.This mentality of designing mainly to solve above two large problems as starting point, has had certain improvement for the rotation of pump impeller inlet fluid and the control of flow velocity.
Summary of the invention:
Technical problem to be solved by this invention is the defect overcoming prior art, provides a kind of water inlet suction casing parts of vertical pump.
Technical problem to be solved by this invention realizes by the following technical solutions.
A kind of water inlet suction casing parts of vertical pump, it is characterized in that: its main body comprises housing and wheel hub, blade is provided with between housing and wheel hub, the wheel hub of this part and housing couple together by blade, simultaneously support both of them the space onesize with its formation eight, this space be fed sheet of a media by space, described blade comprises two kinds, be respectively blade one and blade two, two kinds of spacing with blades are uniformly distributed on wheel hub, housing.
Described blade is simple prismatic blade, blade outlet angle is 90 °, the medium that can ensure to leave blade without spin enter impeller, the effect being its racemization embodies, equally, except playing, racemization ensures that fed sheet of a media flowing more adapts to except the situation of impeller blade, also play reduce when fed sheet of a media meets due to flow velocity etc. do not bring the effect of shock energy consumption.
Described blade is thinning gradually by housing, a little spreading morphology is defined like this in overall structure, more be conducive to fed sheet of a media energy from kinetic energy to the conversion of pressure energy, impeller can be controlled or vane inlet speed is certain value, actual, control and ensure that the cavitation erosion of pump to a certain extent.The thinning trend of blade more makes the medium flowed out from each space have less shock when departing from blade, reduces the possibility of energy ezpenditure.
Arrange between impeller of the present invention circumference homogeneous phase, the medium of this part will be entered separately that the reduction of to cross in fluid space as early as possible that the non axial rotational speed that the process medium in this space of runoff self exists is diminishing gradually saves space: axially long, radial short.
As the inlet segment of pump, there is good Streamline Design its inside, is more conducive to the flowing of fed sheet of a media;
Divide equally blade for eight and play support, connection, water conservancy diversion, current stabilization effect respectively.
Accompanying drawing illustrates:
Fig. 1 is structural representation of the present invention;
Fig. 2 is B-B schematic diagram in Fig. 1.
Embodiment:
The technological means realized to make the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with concrete diagram, setting forth the present invention further.
A kind of water inlet suction casing parts of vertical pump as shown in Figure 1, its main body comprises housing and wheel hub, blade is provided with between housing and wheel hub, the wheel hub of this part and housing couple together by blade, simultaneously support both of them the space onesize with its formation eight, this space be fed sheet of a media by space, blade wherein comprises two kinds, be respectively blade 1 and blade 22, two kinds of spacing with blades are uniformly distributed on wheel hub, housing.
Blade is wherein simple prismatic blade, blade outlet angle is 90 °, the medium that can ensure to leave blade without spin enter impeller, the effect being its racemization embodies, equally, except playing, racemization ensures that fed sheet of a media flowing more adapts to except the situation of impeller blade, also play reduce when fed sheet of a media meets due to flow velocity etc. do not bring the effect of shock energy consumption.
Blade is as described in Figure 2 thinning gradually by housing, when this flow to N-N cross section from M-M cross section, sample defines a little spreading morphology in overall structure, more be conducive to fed sheet of a media energy from kinetic energy to the conversion of pressure energy, impeller can be controlled or vane inlet speed is certain value, actual, control and ensure that the cavitation erosion of pump to a certain extent.The thinning trend of blade more makes the medium flowed out from each space have less shock when departing from blade, reduces the possibility of energy ezpenditure.
More than show and describe basic principle of the present invention, major character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
