Abstract
The invention discloses an opposite-rotation centrifugal air pump achieving axial air inflow through one end. The air inflow and outflow structure of the air pump is changed, and the structural design of a flow channel is adjusted, so that the flow channel is conical. The principle that a coaxial opposite-rotation structure is adopted for carrying out secondary reverse acceleration on fluid entering a suction system is adopted, and therefore the suction capacity of the air pump to fluid is improved. Under the condition of the same volume and motor power, the suction capacity of the single opposite-rotation air pump is more than 2.2 times that of a traditional air pump system. The opposite-rotation air pump is novel in structure, high in technical content, convenient to manufacture and convenient to apply and popularize and has innovativeness.
Description
Technical field
The invention discloses a kind of one end axial admission to turning centrifugal pump, belonging to gas suction-discharge technical field.
Background technique
Along with social development, and increasingly sharpen to the demand of the energy, suction capactity is stronger, and less Novel air pump that consumes energy will be used more widely.This technology is derived from the advanced flow control technique being about to be applied in aeroengine of future generation, under the prerequisite that, noise lower in power consumption is less, achieve small volume compact type air pump to air mass flow, high efficiencyly to transport.Actual measurement shows, the equipment of a wastepaper basket size just can realize in 10 minutes the thorough circulation of air in the office space of area 50 square meter, floor height 3 meters, filtration and purification.
Summary of the invention
The object of the invention is to realize higher pumping efficiency, providing a kind of one end axial admission to turning centrifugal pump.
A kind of one end axial admission is to turning centrifugal pump, and it is characterized in that, comprise the dual-rotor structure of asymmetric installation, its air intake structure changes single sided entry into by two ends air inlet;
Supply fan is positioned at air pump entrance location, and is in the gas inlet position of centrifugal impeller;
Two rotor subtends are installed, and during work, two rotors turn on the contrary.
The invention has the advantages that:
(1) greatly improve the suction capactity of air pump system, when same volume and power of motor, single cover is more than 2.2 times of conventional air pumps system to the suction capactity turning air pump;
(2) to a certain extent, achieve the object that power consumption reduces, because the raising of suction capactity and the secondary counter of air are to acceleration, for identical operating conditions, single cover is to turning the power consumption of air pump less than 70% of conventional air pumps.

Embodiment
Below in conjunction with drawings and Examples, the present invention is described in further detail.
The present invention be a kind of one end axial admission to turning centrifugal pump, as shown in Figure 1, comprise suction port 1, one-level fan 2, motor 3, secondary fan 4, air outlet 5;
The mounting structure of one-level fan 2, motor 3, secondary fan 4 as shown in Figure 1; Suction port 1 is positioned at the serrated end of one-level fan 2, and air outlet 5 is positioned at the side of secondary fan 4, and air pump overall structure is cone type, and it is conducive to reducing the centrifugal loss in air-flow pressurization;
Motor 3 is positioned at fan inside, and its running shaft is fixed with two-stage fan respectively, thus drives fan to rotate, and upper and lower two fans are mounted opposite, and make two fans coaxial, reverse to turning, one end of two fans is all fixed with bearing.
Working principle and process:
Bilobed wheel of the present invention is to when turning air pump structure work, motor 3 drives fan to rotate, one-level fan 2 is made to have gettering ability, the inside of one-level fan 2 is entered from the air of suction port 1 suction, through the rotary compression of one-level fan 2, air-flow enters the inside of secondary fan 4, due to the sense of rotation that secondary fan 4 is contrary, so through the reverse acceleration of secondary fan 4, thus the secondary compression realized air-flow, at this moment air-flow has higher speed and pressure, and air pump can be made to realize higher suction capactity.
Because air-flow during work is by after twice rotary compression, velocity attitude changes to horizontal suction port 1 perpendicular to suction port 1 direction again and gives vent to anger, namely secondary fan 4 lateral, reduces the wastage so air inlet/outlet result is designed with to be beneficial to, thus improves the working efficiency of air pump.
The present invention in actual use, due to stronger suction capactity, can realize operating range larger under under more stingy pump volume under identical operating conditions and energy consumption or same volume and energy consumption.And be mainly the innovation of rotor mounting structure due to the present invention, do not introduce new design of part and labyrinth layout, so be readily embodied in the product improvement on existing air pump production line, for product promotion advantageously.And less volume size also contributes to family oriented market more widely.
Embodiment:
Adopt a kind of bilobed wheel being applicable to small-sized wind power generator of the present invention to turning wind wheel structure, carry out blasting research, incoming flow wind speed gets 7m/s, 8m/s, 9m/s and 10m/s respectively.Measure same design size (identical aerofoil profile, identical maximum turning radius) single-wheel wind wheel structure respectively and to turning wind wheel structure output power, obtain experimental result as following table:
Table 1 experimental configuration
Visible by table 1, 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 50% in wind energy utilization.
