Description
Technical field
The invention belongs to diesel engine test technical field, be specifically related to a kind of diesel engine test room ventilating system.
Background technology
In the time that diesel engine test room carries out various diesel engine test, the environment temperature in laboratory can raise along with the increase of test period.This is because the surface temperature of the equipment such as diesel engine, dynamometer and smoke exhaust pipe can increase gradually in process of the test, and cause to radiation in laboratory and conduction heat.Therefore laboratory must be furnished with ventilating system, promotes the Air Flow in laboratory, keeps certain test indoor environment temperature.Conventionally ventilating system comprises ventilating fan and air exhauster, once blower fan starts just in declared working condition work, in the time carrying out light duty diesel engine test or the little load test of high and medium power diesel engine, the surface temperature of the equipment such as diesel engine, dynamometer and smoke exhaust pipe is lower, heat to radiation in laboratory and conduction is few, so ventilation amount that need not be too many, will cause the waste of electric power like this.In addition, the duty of ventilating fan, air exhauster can produce unmatched phenomenon because of the variation of test indoor conditions, can cause laboratory's inner air and outer air pressure reduction larger, and the lighter causes laboratory gate to be not closed completely, the gas leakage that leaks out, severe one all causes potential safety hazard to whole fabric structure.Therefore the present invention relates to a kind of diesel engine test room ventilating system, by increase Frequency Converter Control on laboratory's air inlet, air exhauster, the ventilation of laboratory can be adjusted at any time according to the variation of test indoor environment temperature, keep lower indoor environment temperature and less temperature fluctuation, can remain that again laboratory's inner air and outer air pressure differential levels off to zero, has saved energy resource consumption simultaneously.
Summary of the invention
Technical problem to be solved by this invention will provide a kind of diesel engine test room ventilating system exactly.The ventilation of Neng Shi of the present invention laboratory can adjust at any time according to the variation of test indoor environment temperature, keep lower indoor environment temperature and less temperature fluctuation, can remain that again laboratory's inner air and outer air pressure differential levels off to zero, has saved energy resource consumption simultaneously.
The present invention solves the problems of the technologies described above the technical scheme of employing: a kind of diesel engine test room ventilating system, it comprises ventilating fan 4, ventilating fan frequency converter 5, air exhauster frequency converter 6, air exhauster 7, temperature sensor 8, air pressure probe 9, PLC switch board 10 and long-distance control cabinet 11, ventilating fan 4 and air exhauster 7 are arranged on the both sides of described diesel engine test room top, ventilating fan 4 is connected with ventilating fan frequency converter 5, and air exhauster 7 is connected with air exhauster frequency converter 6; Temperature sensor 8 and air pressure probe 9 are arranged on described diesel engine test room top; Ventilating fan frequency converter 5, air exhauster frequency converter 6, temperature sensor 8 and air pressure probe 9 are all connected with PLC switch board 10 by holding wire; PLC switch board 10 is connected with long-distance control cabinet 11 by holding wire.
The present invention compared with prior art its beneficial effect is: use after the present invention, the ventilation of laboratory can adjust at any time according to the variation of test indoor environment temperature, keep lower indoor environment temperature and less temperature fluctuation, can remain that again laboratory's inner air and outer air pressure differential levels off to zero, has saved energy resource consumption simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
The specific embodiment
As shown in Figure 1, a kind of diesel engine test room ventilating system, the ventilation of laboratory can be adjusted at any time according to the variation of test indoor environment temperature, keep lower indoor environment temperature and less temperature fluctuation, can remain again laboratory's inner air and outer air constant pressure, save energy resource consumption simultaneously.It comprises ventilating fan 4, ventilating fan frequency converter 5, air exhauster frequency converter 6, air exhauster 7, temperature sensor 8, air pressure probe 9, PLC switch board 10 and long-distance control cabinet 11, ventilating fan 4 and air exhauster 7 are arranged on the both sides of described diesel engine test room top, ventilating fan 4 is connected with ventilating fan frequency converter 5, and air exhauster 7 is connected with air exhauster frequency converter 6; Temperature sensor 8 and air pressure probe 9 are arranged on described diesel engine test room top; Ventilating fan frequency converter 5, air exhauster frequency converter 6, temperature sensor 8 and air pressure probe 9 are all connected with PLC switch board 10 by holding wire; PLC switch board 10 is connected with long-distance control cabinet 11 by holding wire.
When diesel engine test starts to need ventilating system to start, send startup command by holding wire to PLC switch board 10 by the long-distance control cabinet 11 that is positioned at testing crew operation room, 10 of PLC switch boards send startup command control ventilating fan 4 and air exhauster 7 entrys into service to ventilating fan frequency converter 5 and air exhauster frequency converter 6.Be blown into by ventilating fan 4 and extracted out by air exhauster 7 at test room air, air being produced in laboratory mobile, taking away the heat of the equipment such as in process of the test diesel engine 1, dynamometer 2 and smoke exhaust pipe 3 to environmental radiation in laboratory and conduction.Environment temperature in laboratory is recorded by temperature sensor 8 and sends PLC switch board 10 to by holding wire, in the time that environment temperature rising is greater than setting value, 10 order ventilating fan frequency converters 5 of PLC switch board increase frequency, improve ventilating fan 4 motor speeds, increase rate of air circulation; When environment temperature is lower than when setting value, 10 order ventilating fan frequency converters 5 of PLC switch board reduce frequency, reduce ventilating fan 4 motor speeds, reduce rate of air circulation.Environmental pressure in laboratory records and is real-time transmitted to PLC switch board 10 by air pressure probe 9, in the time that laboratory's inner air and outer air pressure differential approaches warning value, adjust the motor speed of air exhauster 7 by the PLC switch board 10 supply and exhaust fan frequency converter 6 of giving an order, the air output that Control experiment is indoor, remains in safe range the environmental pressure in laboratory.After off-test, send and cease and desist order to PLC switch board 10 by holding wire by long-distance control cabinet 11,10 of PLC switch boards send and cease and desist order to ventilating fan frequency converter 5, air exhauster frequency converter 6, and ventilating fan 4 and air exhauster 7 shut down, and laboratory's ventilating system quits work.Because laboratory's ventilating system can be according to test situation, the equipment such as diesel engine 1, dynamometer 2, smoke exhaust pipe 3 are to how many adjustment ventilating fans 4 of function of environment heat emission amount in laboratory and the duty of air exhauster 7, avoid two blower fans all the time in declared working condition work, thereby reduced energy resource consumption.
The present invention is a kind of diesel engine test room ventilating system, use after the present invention, the ventilation of laboratory can adjust at any time according to the variation of test indoor environment temperature, keep lower indoor environment temperature and less temperature fluctuation, can remain that again laboratory's inner air and outer air pressure differential levels off to zero, has saved energy resource consumption simultaneously.
