The diesel generator set should be regularly maintained and checked, and the operation of inspection must be carried out after the safe operation instructions are mastered before the unit can be started for maintenance.
Firstly: Preparation steps before starting up:
1. Check whether the fasteners and connectors are loose and whether the moving parts are flexible.
2. check the reserves of fuel, oil and cooling water, to meet the basic requirements of use.
3. check the load air switch on the control cabinet, should be in the disconnect position (or set OFF), and set the voltage knob in the minimum voltage position.
4. the preparation of the diesel engine before starting, in strict accordance with the requirements of the operating instructions (different types of models may be slightly different).
5. If necessary, notify the power supply department to pull off the circuit breaker or set the switch switch of the mains and diesel generator switching cabinet in the middle (neutral state) to cut off the mains high-voltage power supply line.
Secondly: Formal starting steps:
1. no-load starting diesel generator set according to the diesel engine operating instructions for the method of starting.
2. according to the requirements of the diesel engine instruction manual to adjust the speed and voltage (automatic control unit does not need to adjust).
3. after everything is normal, the load switch is placed to the generator end, according to the reverse operation procedure, slowly close the load switch step by step, so that it enters the working power supply state.
4. always pay attention to whether the three-phase current is balanced during operation, and whether the electrical instrument indications are normal.
Thirdly: Matters that should be noted during the operation of diesel generator sets:
1. regularly check the water level, oil temperature and oil pressure changes, and make a record.
2. the occurrence of oil leakage, water leakage, gas leakage should be repaired in time, stop working when necessary, and report to the manufacturer for after-sales on-site treatment.
3. Make operation record form.
Fourth: Diesel generator shutdown matters:
1. Gradually remove the load and turn off the automatic air switch.
2. if it is a gas starting unit, should check the air pressure of the air bottle, such as low air pressure, should be filled to 2.5MPa.
3. according to the use of diesel engine or diesel generator set equipped with the instruction manual to stop.
4. do a good job of diesel generator set cleaning and health work, ready for the next boot.
