Generator rental manufacturers introduce diesel generator GAC electronic governor

Generator rental manufacturers introduce diesel generator GAC electronic governor

The speed controller is a fully electronic device designed to control the speed of the diesel engine with fast and accurate response to instantaneous load changes. This is a closed loop control that controls the operation of the diesel engine when connected to a matching electronic actuator and the magnetic speed sensor signal used.

The engine speed information of the speed controller is usually obtained from a magnetic speed sensor. Any other signal generating device may be used to provide an alternating frequency suitable for the engine speed and meet the characteristics of voltage input and frequency range. The magnetic speed sensor is generally installed approximately in the iron teeth of the engine drive. This is usually a ring gear. The number of teeth passing through the magnetic speed sensor matches the speed of the engine.

When the speed signal is obtained by the controller, the signal is amplified and shaped by the internal circuit to provide an analog speed signal. If the speed sensor cannot detect the signal from the speed sensor, the output circuit of the speed controller will turn off all current to the actuator.
When the engine is running, the actuator can be adjusted from off to full fuel position. Once the generator rental engine is started, after the engine speed adjustment is completed, the engine will reach its working speed under its adjustment. Ideally adjust the engine speed, the actuator will give enough current to maintain the ideal speed, independent of the load.

调节方法: The functions of each potentiometer of the GAC ESC, the adjustment method of the generator rental manufacturer :
1: STARTING FUEL The starting fuel supply can adjust the amount of smoke when starting. Adjusting the fuel supply clockwise increases the smoke level, but the start is smooth. On the other hand, the smoke reduction effect is poor.
2: SPEED RAMPING rising rate is the rising rate from idle to full speed. The larger the rising rate, the shorter the time, and adjusting the rising rate clockwise to decrease the time increase. On the contrary, time is shortened.
3: DROOP speed drop The rate of decrease of the speed of the oil machine from no-load to load. Mainly parallel operation
Improve running performance while traveling.
4: IDLN idle speed adjustment during idle speed, clockwise increase speed. Conversely, slow down.
5: SPEED Full speed speed adjustment at full speed position, clockwise speed adjustment. Conversely, slow down.
6: GAIN proportional gain
7: STABILITY Stability <Operation> adjustment when the oil machine is unstable: (the oil circuit of the oil machine should be checked first)
1: Adjust GAIN (proportional gain) clockwise to make the oil machine run unstable and then turn it counterclockwise to a point after the operation is stable.
2: Adjust STABILITY clockwise to make the oil machine run unstable and adjust counterclockwise to
After a while, the operation is stable.
Observe GAIN <proportional gain>, STABILITY stability> Do not set the two potentiometers at the lowest position. If they are at the lowest position, turn the C1 \ C2 switch and repeat the two steps to achieve satisfactory results.
C1: Lead \ lag circuit switch, usually in the ON position. If the governor has good performance but the actuator jumps quickly, please set the switch to the OFF position.
C2: The remaining frequency suppression line is usually in the OFF position. If the actuator is not swinging normally due to soft engagement, please turn the switch to the ON position.
Differential time compensation: when the gain is small, the car will travel quickly and the jumper will be cut off (E1—E2):
For example, a capacitor is welded to E2 (-) E3 (+) in a slow-speed traveling car, and the capacitor is 15V10-20mfd.
㈡Actuator [External Type]
The actuator uses a proportional coil to control the throttle according to the current.
Actuator plugs are connected in series / parallel according to different voltages <12V / 24V>.
㈢Speed sensor The speed sensor consists of permanent magnets, coils, leads, etc., and is mounted on the flywheel housing of the oil engine. When the oil machine rotates, the flywheel tooth cuts the speed sensor magnetic field and the coil senses the pulse potential. When a flywheel tooth passes the speed sensor, the speed sensor senses a pulse potential. This pulse potential is input to the GAC electronic speed control for processing and compared with the set value Control the current of the actuator,
The actuator controls the engine speed.

Attachment: system parameters performance working voltage: 12V / 24VDC
Input speed signal voltage: ≥3ⅤAC resistance 560 / 1KΩ When the voltage is lower than 3ⅤAC, the installation position of the speed sensor can be adjusted.
Actuator input voltage:
Adjust the speed: short KL, 1-5% can be adjusted.
Speed fine-tuning range: ± 200r / minhttp: //hzbxx.cn/
