Cummins diesel generator needs to be preheated before starting, and then in the power, after the power controller starts to work to start the generator, in order to ensure the safe operation of the generator, before the operation to check whether the line is firmly connected, such as abnormal conditions in the operation of the equipment, to stop immediately for inspection, and the equipment should not be stacked around inflammable and explosive, and do a good job of fire measures, The following is a detailed introduction to you.
I. Starting steps of Cummins diesel generator set
1. Preheating of generator set: the unit equipped with preheater can be preheated according to the ambient temperature before starting. The control screen with preheating button can control the engine to start heating for the purpose of preheating.
2. Power ON the generator set: switch the key switch of the control screen from OFF to ON position, and observe the instrument background light on the panel, indicating that the control screen has been powered on, and the fuel of the unit is on state, and the controller of the electronic speed controller or the electric injection unit is also in working state.
3. Generator set startup: The control screen of some units has idle/full speed switch. Users can choose whether to idle or full speed one-time startup according to the actual needs. Generally, the idle running time should not exceed 5 minutes. The unit should not run at idle speed for a long time. Press the start button, the duration is not more than 30 seconds, the engine starts under the drive of the start motor, once the start is successful, you can release the start button, the unit into the running state.
Ii. Safe operation Rules of Cummins diesel Generator Set
1. Before starting the generator, it is necessary to carefully check whether the wiring of each part is correct, whether the connecting part is secure, whether the brush is normal, whether the pressure meets the requirements, and whether the grounding wire is good.
2. Put the resistance value of the excitation rheostat in the maximum position before starting, disconnect the output switch, and the generator set with clutch should release the clutch. Start the diesel engine with no load first, run smoothly, then start the generator.
3. After the generator starts running, attention should be paid to whether there is mechanical noise, abnormal vibration and other conditions. After confirming that the situation is normal, adjust the generator to the rated speed, adjust the voltage to the rated value, and then close the output switch to supply power to the outside. The load should be gradually increased and strive for three-phase balance.
4. The parallel operation of the generator must meet the conditions of the same frequency, the same voltage, the same phase and the same phase sequence.
5. Generators ready for parallel operation must be in normal and stable operation.
6. Generators running in parallel should reasonably adjust the load and evenly distribute the active and reactive power of each generator. Active power is regulated by diesel throttle and reactive power is regulated by excitation.
7. The operating generator should pay close attention to the sound of the diesel engine (driven by the land generator set) and observe whether various instruments indicate within the normal range. Check whether the running part is normal and the temperature rise of the generator is too high. And make a good running record.
8. When stopping the unit, first reduce the load, restore the excitation rheostatic, so that the voltage is reduced to the minimum value, and then cut off the switch in order, and finally stop the diesel engine operation.
9. Mobile generator, the bottom frame must be parked on a stable basis before use, and it is not allowed to move during operation.
10, the generator in operation, even if not excited, should also be considered with voltage. Do not work on the leading line of the rotating generator, touch the rotor or clean it with your hands. The operating generator shall not be covered with canvas or other objects.
11. After the generator is overhauled, it is necessary to carefully check whether there are tools, materials and other debris between the rotor and stator slots, so as not to damage the generator during operation.
12. All electrical equipment in the machine room must be grounded reliably.
13. It is forbidden to stack sundry materials and inflammable and explosive materials in the machine room. Except for the personnel on duty, it is forbidden to enter without permission.
14. The room should be equipped with necessary fire equipment, in case of fire accident should immediately stop the power supply, turn off the generator, and use carbon dioxide or carbon tetrachloride fire extinguisher.
