The regulator is a device that regulates the voltage. First, it prevents the battery from being damaged by excessive voltage, and at the same time cuts off the line between the battery and the battery when the voltage of the generator is too low. The above is a DC generator. If it is an alternator, it only has a voltage regulator function.
The regulator is generally not allowed to disassemble the cover during use. Normally, a full inspection and maintenance is performed every 200 hours of work. The content is as follows:
1, remove the protective shell, check the contact surface for dirt and burning. If there is dirt, wipe the contact surface with a cleaner paper. If the contact has ablation or flat surface and causes poor contact, it is generally smoothed with “00” sand paper or sand bar, and then wiped clean with clean paper.
2. Check the firmness of each connector and measure the resistance of the resistor and each coil. If there is any damage, repair or replace the new one.
3. Check the closing voltage and reverse current of the circuit breaker, the limit voltage of the voltage regulator, the limit current of the throttle, and the clearance and air gap of various contacts. If it does not meet the requirements, it should be adjusted.
4. Check the adjusted regulator. When starting the diesel engine, pay attention to the indication of the charging current meter pointer. If the diesel engine is running at a speed higher than average, the ammeter pointer still points to the “-” side. This indicates that the contacts of the circuit breaker are not disconnected, and the grounding switch should be quickly disconnected; otherwise, the battery, regulator and charging generator will be damaged. . If the indicator of the ammeter still points to “0” after the diesel engine is started to the rated speed, the adjustment is not adjusted according to the technical requirements and the inspection and adjustment should be performed again.
