Abstract
The utility model discloses a high-efficiency energy-saving vertical type pitot pump. A pitot tube in a cavity of the pitot pump comprises an inlet section and an outlet section, wherein an included angle between the central axis of the inlet section and the central axis of the outlet section ranges from 95 degrees to 100 degrees, and the central axis of the inlet section deflects towards an upper cover of a pump case. As for the high-efficiency energy-saving vertical type pitot pump, the structure is improved and the efficiency is increased.
Description
Technical field
The utility model relates to the water pump field, is specifically related to the vertical Pitot pump of a kind of high-efficiency and energy-saving type.
Background technique
At present, the Pitot pump is a kind of low-flow high-lift low specific speed pump according to the development of pitot tube principle, working principle is after liquid is inhaled into impeller with pump case loam cake one, advancing the people rotates cavity rotation and obtains kinetic energy, collect the kinetic energy fluid by static pitot tube again, be converted to high pressure energy fluid output.
The pitot tube of existing Pitot pump, the angle of the central axis of inducer and the central axis of outlet section is 90 °, and the curvature internal diameter at the turning of inducer and outlet section is smaller, therefore at 90 ° of turnings because the viscous flow pressurization, produce bigger local resistance loss, made the efficient of Pitot pump be subjected to certain restriction.
The model utility content
The utility model provides the vertical Pitot pump of high-efficiency and energy-saving type of a kind of architecture advances, efficient raising in order to overcome the deficiency that above prior art exists.
The purpose of this utility model realizes by following technological scheme: the vertical Pitot pump of this high-efficiency and energy-saving type, pitot tube in the Pitot pump chamber comprises inducer and outlet section, it is characterized in that: the angle of the central axis of described inducer and the central axis of outlet section is between 95 °~100 °, and the central axis of inducer is to the deflection of pump case loam cake.
As a kind of preferred structure, the maximum curvature internal diameter at the inducer of described pitot tube and the turning of outlet section is 40mm, and the minimum curvature internal diameter is 30mm.
In the practical application, described inducer is in the rotation cavity of pump case loam cake and pump housing lower cover formation, and the pump case loam cake connects electric machine main shaft.
As a kind of preferred structure, cover the impeller of integrally casting moulding under the described pump housing.
The cross section of described inducer is the elliptic flow line style, and the cross section of outlet section is circular, helps reducing to stream and resistance.
The utility model has following advantage with respect to prior art: the vertical Pitot pump of this high-efficiency and energy-saving type improves the pitot tube structure in the existing Pitot pump chamber, increased the angle of the central axis of the central axis of inducer and outlet section, increased the curvature internal diameter at the turning of the inducer of pitot tube and outlet section, to reduce the local pressure loss that remains in a standstill, to increase the conversion of kinetic energy to pressure energy, reduce the loss of energy, improve the efficient of pump, implementation structure is simple, compact dimensions, the pressure height, stable single-stage small flow high-pressure service pump, the method validation by numerical simulation and object test adopt this structure pitot tube will make the efficient of Pitot pump improve about 5%.
This pitot tube can adopt forging type manufacturing processing.The present invention adopts the pitot tube principle of the stagnation supercharging of flowing in conventional centrifugal pump and the space technology, its flow lift curve smoothing, the hump phenomenon that does not have low specific speed centrifugal pump flow lift curve, liquid output no pulse is applicable to that fluid delivery requires production station more stably in the industries such as oil, chemical industry, chemical fertilizer, metallurgy, mining, carbon black, papermaking.

Embodiment
The utility model is described in further detail below in conjunction with drawings and Examples.
Drive electric machine main shaft 4, pump case loam cake 5 and 7 rotations of pump housing lower cover by motor or gear (general rotating speed is at 2000-4000r/min), thus whole rotation cavity 3 high speed rotating.Enclosed impeller 2 is cast on the pump housing lower cover 7, together with pump housing lower cover 7 high speed rotating.Place an actionless pitot tube 6 in the rotation cavity 3 of high speed rotating, the inlet of pitot tube 6 is near the inward flange of rotation cavity 3, after liquid sucks intake pipe 1, through impeller 2 centrifugation accelerates, liquid velocity at the cavity edge is the highest, and the peripheral liquid of high speed rotating is pressed towards pitot tube 6 inlets, can be converted into pressure energy to speed by pitot tube 6, obtain steady pulseless highly pressurised liquid, discharge from outlet pipe 8.
Above-mentioned embodiment is a preferred embodiment of the present utility model; can not limit the utility model; other any change that does not deviate from the technical solution of the utility model and made or other equivalent substitute mode are included within the protection domain of the present utility model.
