Description
Technical field
The utility model belongs to field of electrical control, and in particular to a kind of trim air register tests system.
Background technology
Air trim air register is a part for plane environmental control system.Trim air register is used as deicing valve,
Hot-air can be provided to turbine delivery outlet and prevent the freezing process at condenser.Trim air register is carried out maintenance and tested
When, trim air register is turned off using the TT＆C system of specialty and opens and indicate that electronic switch state is very necessary.
But existing test system still compares for the test all-purpose performance of the air trim air register of different size
Poor, measurement range and precision for parameter are not all also very high, and using effect is less desirable.
The content of the invention
Goal of the invention：In order to overcome the deficiencies in the prior art, a kind of universal performance height, measurement parameter face are provided
Extensively, trim air register test system with high accuracy.
Technical solution：To achieve the above object, the utility model provides a kind of trim air register test system, including comprehensive
Logical control circuit module, the integrated logic control circuit module respectively connected XY recorders, power amplifier sum number
Aobvious electrical secondmeter, the power amplifier respectively connected Digital Logic security circuit and number splits phase device, and the number splits phase device
It is connected to signal generator.
Further, the integrated logic control circuit module is also connected with digital photoelectric angular displacement sensor, described
Digital photoelectric angular displacement sensor is connected to digital display angle meter, and the digital display angle meter is connected to XY recorders.
Further, the signal generator is connected to digital display frequency meter.
Further, the integrated logic control circuit module passes through alterating and direct current module for power supply.
The utility model intermediate power amplifier is one of key component of whole system, therefore the element circuit is using a variety of
Advanced circuit design method, circuit use the wide-band amplifier with depth Current Negative Three-Point Capacitance, ensure that current drive unit is divided into
Constant-current source；Stable voltage-current converter circuit ensures that circuit has and stablizes rational voltage and current ratio, simultaneously because technical conditions
It is required that the output of valve current driver unit electric current is larger, loaded pressure drop is also larger, and common operational amplifier can not meet this certainly
The requirement of sample, therefore use dedicated high current special power integrated chip.
Integrated logic control circuit module, Digital Logic security circuit and number split the crucial portion that phase device is also whole system
/ mono-, it is responsible for controlling the starting and stopping of workpiece motor and the logic and security of rotation direction.Therefore to the element circuit into line number
Wordization designs, and using a variety of advanced digital circuit design methods, ensures the stabilization, reliable and precisely of workpiece motor operation.
The angular surveying of workpiece uses high-precision intelligent digital display angle meter and digital photoelectric angular displacement sensor, improves
Measurement accuracy, the accuracy that ensure that test.
The time of workpiece, frequency measurement also using high-precision intelligent digital display frequency meter and digital display electrical secondmeter, improve measurement
Precision, the accuracy that ensure that test.
Advantageous effect：The utility model compared with prior art, possesses the opening and closing of control valve, measures simultaneously
The angle of valve operation, the potentiometric output voltage of valve, realization control valve automatically open stopping and stopping are automatically closed, surveys
The multiple functions such as frequency of motor operation, not only greatly improve for different rule in the shut-in time of amount valve and governor valve
The measurement versatility of the air trim air register of lattice number, and be also obtained for for the measurement range and precision of parameter bright
Aobvious promotion.
