Description
Technical field
The utility model relates to the motor on octane number testing machine, in particular, relates to a kind of engine speed COMM communication for octane number machine.
Background technique
In the octane number determination based on standard variable compression ratio engine, according to < < GB/T503 testing octane number of gasoline method (motor method) > >, ASTM D2700 and < < GB/T5487 octane number machine determination method (organon) > >, the requirement of ASTM D2699 standard, need to measure respectively motor octane number (MON) in high engine speeds running (900 revs/min) situation and the research octane number (RON) (RON) in low-speed running (600 revs/min) situation, the anti-knock index requiring in gasoline product quality standard=(MON+RON)/2.For this reason, octane number machine needs to support this two kinds of operating modes simultaneously.
Traditional method is to adopt constant speed starting electrical machinery, by adopting two different driving pulleys of diameter to realize motor method and the different requirements of organon to rotating speed.So, when two kinds of methods are switched, need to carry out mechanical dismounting, change belt wheel, bother time-consumingly, owing to guaranteeing by register ratio, control of engine speed also cannot be accomplished precisely.
Model utility content
The utility model is for the technical problem existing in above-mentioned prior art, a kind of engine speed COMM communication for octane number machine is provided, adopt variable speed starting electrical machinery, with one group of drive pulley, connect belt and can realize the switching of motor between two specific speeds.Thereby make the switching of testing octane number of gasoline machine between motor method operating mode and organon working condition tests simple and easy to do, and needn't carry out a large amount of mechanical disassemble and assemble works.
In order to achieve the above object, the utility model is achieved through the following technical solutions:
A kind of engine speed COMM communication for octane number machine, comprise: motor, variable speed starting electrical machinery, one group of drive pulley being formed by driving wheel and driven wheel and belt, described motor and variable speed starting electrical machinery are arranged on octane number testing machine pedestal, described driving wheel is arranged on and starts on variable speed starting electrical machinery axle, described driven wheel is arranged on engine shaft, driving wheel is connected by described belt with driven wheel, when described variable speed starting electrical machinery carries out the switching of rotating speed, by drive pulley and belt, drive motor, thereby realize the switching controls to engine speed.
Also comprise that one is arranged on speed regulation frequency converter, the diverter switch on octane number machine enclosure, described diverter switch is used for selecting rotating speed gear, described speed regulation frequency converter obtains after switching command, according to new rotating speed, drive variable speed starting electrical machinery, through drive pulley and belt, drive motor, thereby realize the switching to engine control rotating speed.
Described variable speed starting electrical machinery is directly switched and is realized rotating speed and switch by electrode.
Described variable speed starting electrical machinery adopts permagnetic synchronous motor.
Described diverter switch is arranged on the operation panel of octane number testing machine.
Engine speed COMM communication for octane number machine provided by the utility model, compared with prior art has the following advantages:
Adopt variable speed starting electrical machinery to carry out rotating speed switching, with one group of drive pulley and belt, connect and can realize the switching of motor between two speed, thereby make the switching of testing octane number of gasoline machine between motor method operating mode and organon working condition tests simple and easy to do, and needn't carry out a large amount of mechanical disassemble and assemble works.Variable speed starting electrical machinery can be realized variable-speed operation by a speed regulation frequency converter and diverter switch, also can directly adopt variable speed starting electrical machinery to be switched and realized double speed and switch by electrode, and dispense speed regulation frequency converter.
Accompanying drawing explanation
Fig. 1 is apparatus structure schematic diagram provided by the utility model;
Embodiment
Below in conjunction with the drawings and specific embodiments, the technical solution of the utility model is described in further detail.
Engine speed COMM communication one example structure schematic diagram provided by the utility model shown in Fig. 1, this embodiment is on the testing octane number of gasoline machine of an alterable compression ratio.Speed regulation frequency converter 1 is arranged on the cabinet of octane number machine, variable speed starting electrical machinery 2 is arranged on octane number testing machine pedestal, and variable speed starting electrical machinery 2 adopts permagnetic synchronous motor at present.Diverter switch 7 is arranged on the operation panel of octane number testing machine, adopts on off switch.
Driving wheel 3 is arranged on the axle of variable speed starting electrical machinery 2, and driven wheel 4 is arranged on motor 6 axles, by belt 5, connects; Motor 6 is arranged on octane number testing machine pedestal.
When needs carry out octane number machine rotating speed switching between motor method and organon, operator only need to operate diverter switch 7, speed regulation frequency converter 1 obtains according to new rotating speed, driving variable speed starting electrical machinery 2 after switching command, through driving wheel 3, driven wheel 4 and belt 5 in one group of drive pulley, drive motor 6, thereby realize the switching to engine control rotating speed.
Also can directly adopt variable speed starting electrical machinery 2 to switch by electrode, and without speed regulation frequency converter, realize the effect that double speed switches.
Above-described embodiment is only for the utility model is described, but and is not used in the protection domain that limits claim.Every equivalents of carrying out on the basis of technical solutions of the utility model and improvement, all should not get rid of outside protection domain of the present utility model.
