speed governer test bench :working voltage, three-phase ac 380 v, 50 hz ac, 4 kw
speed governer test bench: test speed range: 1
one:Introduction of the joint regulator test
Joint regulator test rig is a kind of testing and calibration governor performance test platform, is the internal combustion engine car plants, locomotive, especially governor repaired with the necessary test equipment, on the function, performance index has reached the leading domestic level, can completely replace foreign similar equipment, meet the requirements of internal combustion engine vehicle each governor of debugging.
Test using the main structure, it can provide test machine hydraulic governor the speed, pressure and heating of the working oil; Also available is needed for the governor of the power signal.
Joint regulator test digital simulation control technology, can realize the digital simulation of diesel locomotive diesel engine generator system, the governor of the test environment is governor and locomotive diesel engine with the actual working condition of the machine. Test is suitable for diesel locomotive engine with QJY - 5, PGEV, PGMV, joint regulator, 302 - B, C, D, and other types of internal combustion engine vehicle changing performance test and commissioning test. Can also be applied to the ship and generator sets with mechanical hydraulic governor of the test.
Test-bed design based on one person operation, test all the circuits are wrong operation protection, to prevent burning of the test bench.
two.The main technical indexes of combined regulator test rig
1, working voltage, three-phase ac 380 v, 50 hz ac, 4 kw;
2, test speed range: 100 ~ 1250 RPM;
3, speed measuring precision: + 1 RPM;
4, governor output displacement measurement range and precision: 0 ~ 40 mm, 0.5.
three,Joint regulator the main performance and function test
Test the speed motor as driving motor, the control system is mainly composed of single chip microcomputer and displacement sensor, speed sensor, all kinds of potentiometer and switch, etc. Displacement sensor detection governor the output displacement of the signal, the speed sensor governor speed signal. Both signal and running speed potentiometer, load potentiometer the voltage signal is sent to the microcomputer system together, through the simulation calculation, and output a PWM control signal to control motor driver circuit to control the operation of the control motor speed. Motor drive governor after connecting shaft and bushing together.
