Technical field
The utility model relates to the oxygenerator field, mainly is a kind of oxygenerator frequency converting and energy saving device.
Background technology
The VPSA oxygenerator utilizes nitrogen in the zeolite molecular sieve selective adsorption air, because the characteristic that the capacity of absorption nitrogen increases with the rising of nitrogen pressure, by the working pressure of change adsorption bed, thus make molecular sieve periodically absorption nitrogen make oxygen separation out, form the purpose of oxygen enrichment.The equipment of VPSA oxygenerator power consumption mainly is gas blower and vacuum pump; The mode of speed regulation that adopts at present, such as variable voltage control, electromagnetic speed-adjusting, winding motor rotor series resistance speed etc., because these speed governing are poor efficiency modes of speed regulation of power consumption, thereby the oxygenerator that many users are joined is not the fully loaded operation, and this just must cause very large waste.
Summary of the invention
The purpose of this utility model is to overcome the deficiency that prior art exists, and provides a kind of minimizing according to load to reduce the rotating speed of vacuum pump and gas blower, reduces gas blower and vacuum pump power consumption, to reach the oxygenerator frequency converting and energy saving device of energy-conservation purpose.
The purpose of this utility model is finished by following technical solution, it is comprised of gas blower, adsorption tower, oxygen surge tank, vacuum pump, valve, on two adsorption towers, this adsorption tower links to each other with the oxygen surge tank by valve by the valve control linkage for described gas blower and vacuum pump.
As preferably, the electric motor in described gas blower and the vacuum pump is powered by three-phase supply, is connected with variable-frequence governor and switch between this electric motor and three-phase supply, and variable-frequence governor is positioned between electric motor and switch.
As preferably, described variable-frequence governor is by the control of variable-frequence governor start-stop controller, and this variable-frequence governor start-stop controller is connected on the variable-frequence governor; Sensor passes the simulating signal of sending by pressure-detecting device and is connected on the variable-frequence governor.
The beneficial effects of the utility model are: the dynamic adjustment by having in this frequency converting and energy saving device, carry soft start and the V/F function of self, reduced the power consumption of gas blower and vacuum pump, have the high characteristics of fractional energy savings.

Embodiment
Below in conjunction with accompanying drawing the utility model is done detailed introduction: shown in accompanying drawing 1,2, the utility model is comprised of gas blower 1, adsorption tower 2, oxygen surge tank 3, vacuum pump 4, valve 5, described gas blower 1 passes through valve 5 control linkages on two adsorption towers 2 with vacuum pump 4, and this adsorption tower 2 links to each other with oxygen surge tank 3 by valve 5.Electric motor 6 in described gas blower 1 and the vacuum pump 4 is connected with variable-frequence governor 7 and switch 8 by the three-phase supply power supply between this electric motor 6 and three-phase supply, variable-frequence governor 7 is positioned at 8 of electric motor 6 and switch.Described variable-frequence governor 7 is by 9 controls of variable-frequence governor start-stop controller, and this variable-frequence governor start-stop controller 9 is connected on the variable-frequence governor 7; Sensor 10 passes the simulating signal of sending by pressure-detecting device 11 and is connected on the variable-frequence governor 7.
1, energy-saving and frequency-variable: for the reliability that guarantees to produce, various production machinerys all leave certain surplus capacity when the power wheel drive of design adapted.Electric motor 6 can not move under full load, and except reaching the power wheel drive requirement, unnecessary moment has increased the consumption of wattful power, causes the waste of electric energy, when pressure is higher, can reduce the travelling speed of electric motor 6, makes its saves energy in constant voltage.When electric motor 6 rotating speeds changed to N2 from N1, the variation relation of its motor shaft power (P) was as follows:
P2/P1=(N2/N1) 3, this shows and reduce the energy-saving effect that motor speed can obtain cube level.
2, dynamically adjust energy-conservation: adapt to rapidly variation of load, supply with maximum efficiency voltage.Variable-frequence governor 7 is provided with 5000 times/second observing and controlling output function at software, remains the output high-efficiency operation of motor.
3, economize on electricity by the V/F function of frequency conversion self: in the situation that guarantees electric motor 6 output torques, can automatically regulate the V/F curve.Reduce the output torque of electric motor 6, reduce received current, reach power save mode.
4, frequency conversion carries soft start energy-saving: when electric motor 6 full voltage starting, because the staring torque of electric motor 6 needs, and absorb from electrical network 7 times motor rated current, and large starting current is namely wasted electric power, voltage fluctuation infringement to electrical network is also very large, has increased line loss and loss on transmission.After adopting soft start, starting current can reduce the impact of starting current to electrical network from 0--motor rated current, has saved the electricity charge, has also reduced to start inertia to the rotating speed impact of the large inertia of equipment, has prolonged the work-ing life of equipment.
5, the raising power factor is energy-conservation: electric motor 6 produces moment by stator winding and rotor winding by electromagnetic action.Winding is because its induction reactance effect.For electrical network, impedance characteristic is perception, and electric motor 6 absorbs a large amount of wattless powers when operation, cause power factor very low.After adopting energy-saving and frequency-variable speed regulator 7, because its performance becomes: AC--DC--AC, behind rectifying and wave-filtering, variation has occured in load characteristic.Variable-frequence governor is resistive to the impedance characteristic of electrical network, and power factor is very high, has reduced reactive loss.
The utility model is not limited to above-mentioned embodiment; no matter do any variation in its shape or material formation; every employing structure design provided by the utility model all is a kind of distortion of the present utility model, all should think within the utility model protection domain.
