The present invention relates to a kind of universal machine, definitely he says, relates to a kind ofly can regulating the air quantity size, and can measure the numerical control blower fan of statistics to vent flow, belongs to the electromechanical integration equipment technical field.
Apply electronic technology and computer technology is rebuild traditional industry, in traditional electronic product, inject electronic technology, enlarge and strengthen the function of use of industrial products, thereby progressively by unit control automatically, the unit automatically control develop into the automatic control of production process, the production looks of rebuilding traditional industry, improving the enterprise technology level is the important directions of China's the nineties all trades and professions technical innovation, also is the historical important task of giving in the epoch.Blower fan is that many industry, traffic department use universal machine very widely, also is one of energy consumption " rich and influential family ".In order to guarantee that many industries such as metallurgy, chemical industry, machinery, weaving, environmental protection, colliery and subway transportation are ventilated, the demand of oxygen supply, when disposing blower fan usually, its rated power all is greater than actual requirement, and its drive motor often also is the AC induction motor that can not realize variable parameter operation.When reality was used, then general the employing at the outlet port of blower fan (individual other also has in its inlet) installing baffle plate realized the throttling adjusting, causes energy loss in vain.For example, require the ratio (coefficient of excess air) of actual oxygen-supplying amount and oxygen consuming amount should be between 1.05-1.10 during boiler burning, because fuel price is more than air expense costliness, the heat power engineering personnel are for the abundant perfect combustion of fuel, just coefficient of excess air C is brought up between the 1.2-1.4, and when Plant model selection, in order to leave surplus and rationally to use, usually again the 70-80% of the operating conditions of equipment design in its declared working condition, like this, boiler is when real work, and the ventilation that its blower fan provides is far longer than its demand, and boiler also always is not in work under the full load condition still more.Under the situation, the low of the usefulness of blower fan just well imagined like this.But in the conventional industries environment, the phenomenon that this energy wastes is can't avoid with helpless.
The purpose of this invention is to provide and a kind ofly can overcome all kinds of defective that exists in the prior art, can regulate the air quantity size, and can measure the NC adjusting and metering fan of statistics, so that conserve energy vent flow.
The present invention includes blower fan, drive motor and control gear, it is characterized in that: blower fan adopts rare earth full speed synchronous machine as drive motor; A plurality of magnetic poles made from rare earth permanent-magnetic material are equipped with in the rotor outside of this motor, its stator coil is circumscribed with two-way variable ratio frequency changer inverter and supplies with as its power supply, and wind speed, blast and the temperature transducer that has pair inverter and blower fan nearby to lay controlled and the programmable controller of data capture.
The present invention comes down to a kind of concrete engineering of claimant's patented technology " NC full-speed electric power/power device) " (patent No. CN93200001.0) and uses.The new type power that this New-type electric machine and numerical control device thereof constitute is actually a kind of bidirectional reversible transducer that is made of energy input end, energy output terminal and control end, its energy of real time computer control switches, make this device have the performance of motor and generator concurrently, and can carry out the Off-design operation operation at random, thereby improve the working efficiency of device greatly, improve energy utilization coefficient.This novel numerical control motive use will be brought very considerable economic and social benefits in industrial products.The present invention is an another typical industry product using above-mentioned patented technology behind numerically controlled beam-pumping unit.
Fig. 1 is that structure of the present invention is formed schematic representation.
Among Fig. 1, the 1st, common centrifugal or axial fan, the 2nd, rare earth synchronous machine at full speed (is claimant's a patented technology product, the patent No.: 91203427.0) as the driving power of blower fan, a plurality of magnetic poles 22 made from rare earth permanent-magnetic material are equipped with in the rotor outside of this motor, 21 of its stator coils are circumscribed with two-way variable ratio frequency changer inverter 3, wind speed, blast and the temperature transducer 61,62,63 that nearby lay in this inverter 3 and blower fan outlet port all is subjected to the control of programmable controller 4, is power supply network.Working method of the present invention and principle and common seemingly fan-type, be after two-way variable ratio frequency changer inverter 3 is obtained industrial-frequency alternating current from electrical network, receive the control command of programmable controller 4, it can be become all variable Ac output of frequency, phase place, electric current, and by the frequency, phase place, size of current, the time length that change output current control rare earth permanent-magnet synchronization motor 2 rotating speed, turn to, acceleration, output torque and running time, drive the blower fan rotation thus.So just can adjust fan condition according to actual needs at random, discharge quantity of fan, blast all can be regulated.Because the data parameters that the some Sensitive Apparatuses that dispose among the present invention are gathered is also made a gift to someone behind the programmable controller, computer is handled, is analyzed data such as these blast, wind speed, temperature, can count the air output of certain section time inner blower more exactly, i.e. the present invention itself can have blower fan, adjusting color controls and air flow rate meter triple functions simultaneously concurrently.
Another characteristic of the present invention is: when it measures accessory fan as the adjusting of the use of connecting with main air blower, except can replenishing adjusting and metering to the air quantity of main air blower, when the air quantity of sending when main air blower has just exceeded the operating mode demand, the present invention can be under the order of programmable controller, change into wind turbine work in good time, it is the wind energy that its blower fan 1 absorption portion main air blower is sent, the p-m rotor 22 that makes rare-earth electric motor 2 is active rotation thereupon, the rotating magnetic field that produces can produce electromotive force in 21 li inductions of stator coil, and draw through two-way variable ratio frequency changer inverter 3, convert its inversion to Ac and send AC network 5 again back to.So both can suitably reduce the air output of main air blower, satisfying the operating mode needs, can also be with the Wind Power Utilization of losing in vain with the baffle plate throttling originally, regeneration becomes behind the electric energy feed-in electrical network again.This point is that common blower fan can not be realized.Because the cancellation baffle plate adopts and directly regulates air quantity, the comparable conventional blower fan economize on electricity 30-40% of the present invention, individual cases can reach more than 60%.The present invention is energy efficient on blower fan not only, the more important thing is the task performance that has improved blower fan and even a whole set of process units, make a whole set of process units that main air blower participates in or system (in this device or system, main air blower is just as subsidiary engine) can realize best production status control, thereby make a whole set of process units or system realize energy conservation object, this effect is just considerable.After for example boiler fan is loaded onto the present invention, just can make the boiler oxygen supply reach as far as possible reasonably design objective, effectively reduce the fuel consumption of boiler, also save electric energy.
The present invention can use separately in the small-power air supply device, and it can possess blower fan, regulator and flowmeter triple functions simultaneously.But,, more can bring into play its special usefulness as being cascaded as the accessory fan use of control, metering with main air blower.It can be installed in the inlet of main air blower, can also still, be contained in the place, outlet air channel of main air blower as the starting drive of main air blower sometimes, and effect is better.Owing to can also use as wind-driven generator, be contained in the present invention in main air blower outlet air channel, its scope of regulating air quantity also just will be widened 1 times than being contained in main air blower inlet.
Although the present invention is an assistant regulating and controlling equipment that is installed on the industrial support facilities (blower fan),, in case after implementing, can utilize situation to make remarkable efficacy for the energy that fundamentally improves a whole set of commercial plant.
