Abstract
The invention discloses a centrifugal contra-rotating air pump with air axially entering from the two ends. On the premise of basically not changing the overall size of a traditional air pump, through reasonable distribution of a fan and a centrifugal turbine, a novel coaxial double-coupling-rotor contra-rotating structure is adopted, the principle that fluid entering a suction system is reversely accelerated for two times is adopted, lower negative pressure is formed inside the suction system, and therefore the fluid suction capacity of the air pump is improved. Under the condition of the same size and motor power, the suction capacity of the single contra-rotating air pump is 1.5 times or above that of a traditional air pump system. The contra-rotating air pump is novel in structure, high in technical content, convenient to manufacture, apply and popularize and creative.
Description
Technical field
The invention discloses the centrifugal to turning air pump of a kind of two ends axial admission, belong to gas suction-discharge technical field.
Background technology
Along with social development, and the demand of the energy being increasingly sharpened, suction capactity is higher, and less Novel air pump that consumes energy will be widely used more. This technology is derived from the advanced flow control technique being about to be applied in aero-engine of future generation, under the premise that, noise relatively low in power consumption is less, it is achieved that small size compact air pump to air mass flow, high efficiency transport. Actual measurement shows, the equipment of a wastepaper basket size achieve that in 10 minutes to area 50 square meter, floor height 3 meters office space in air thoroughly circulation, filter and purification.
Summary of the invention
The invention aims to solve the problems such as conventional air pumps suction capactity low, power consumption height, poor practicability, it is provided that a kind of birotor suitable in air suction-discharge system is to turning air pump.
Being centrifuged turning air pump of a kind of two ends axial admission, it is characterised in that including the dual-rotor structure being symmetrically installed, each rotor includes one-level supply fan and first-stage centrifugal impeller;
Supply fan is positioned at air pump entrance location, and is in the gas feed position of centrifugal impeller;
Supply fan and centrifugal impeller are fixed, and form a rotor;
Two rotors are to installation, and during work, two rotors turn on the contrary.
It is an advantage of the current invention that:
(1) being greatly improved the suction capactity of air pump system, when same volume and power of motor, the suction capactity turning air pump is more than 1.5 times of conventional air pumps system by single set;
(2) to a certain extent, it is achieved that the purpose that power consumption reduces, owing to the raising of suction capactity and the secondary of air reversely accelerate, for identical working condition, single set is to turning the power consumption of air pump less than the 70% of conventional air pumps.

Detailed description of the invention
Below in conjunction with drawings and Examples, the present invention is described in further detail.
The present invention is the centrifugal to turning air pump of a kind of two ends axial admission, as it is shown in figure 1, include supply fan 1, centrifugal impeller baffle plate 2, centrifugal impeller 3, motor 4.
Supply fan 1, centrifugal impeller baffle plate 2, centrifugal impeller 3 mounting structure as shown in Figure 1, 2; Supply fan 1 is positioned at air pump air inlet, and fixes with centrifugal impeller baffle plate 2, and centrifugal impeller 3 is fixed on centrifugal impeller baffle plate 2 bottom, and supply fan is coaxial with centrifugal impeller, three part one rotor of composition;
It is internal that motor 4 is positioned at centrifugal impeller 3, and its rotating shaft and supply fan axle are fixed, thus rotor driven rotates, upper and lower two rotor structures are identical, are mounted opposite, and makes two rotor coaxials, reversely to turning, and supply fan 1 one end of two rotors is used that bearing is fixed.
Operation principle and process:
The bilobed wheel of the present invention is to when turning air pump structure work, motor 5 rotor driven rotates, supply fan 1 is made to have getter capacity, from the inside of the air entrance centrifugal impeller 3 that air inlet 5 sucks, rotary compression through centrifugal impeller 3, a part of gas is directly discharged from gas outlet 5, it is partly into the inside of another impeller of rotor, due to the direction of rotation that another rotor is contrary, so the reverse acceleration of the centrifugal impeller 3 through another rotor, thus realizing the second-compressed to gas, at this moment gas has higher speed and pressure, air pump can be made to realize higher suction capactity.
During due to work, a part of gas gets enter into another primary rotor and carries out second-compressed, is equivalent to decrease the air current flow loss in direction, non-gas outlet, so the present invention not only increases the suction capactity of air pump, and reduces energy consumption.
The present invention in actual use, due to higher suction capactity, it is possible to achieve more stingy pump volume under identical working condition and energy consumption or same volume and working range bigger under under energy consumption. And owing to the present invention essentially consists in the innovation of rotor mounting structure, and be not introduced into new design of part and labyrinth layout, so the product improvement being readily embodied on existing air pump production line, for product promotion advantageously. And less volume size also contributes to family oriented market more widely.
Embodiment:
Adopting a kind of bilobed wheel suitable in small-sized wind power generator of the present invention to turning wind wheel structure, carry out blasting research, incoming flow wind speed takes 7m/s, 8m/s, 9m/s and 10m/s respectively. Measure same design size (identical aerofoil profile, identical maximum radius of turn) single-wheel wind wheel structure respectively and to turning wind wheel structure output, obtain experimental result such as following table:
Table 1 experimental configuration
Visible by table 1, the bilobed wheel of the present invention, to turning wind wheel structure in moderate wind situation, is compared conventional single impeller wind wheel structure, is had the lifting of at least 40% in wind energy utilization.
