4 Check the governor oil level.

5 Check whether the pressure of the air cylinder is sufficient, and put residual water:

6 Check the oil level of the oil tank.

7 Open the dynamometer valve.

8 Turn on the pre-lube oil pump and supply oil to the lubrication system.

9 Weeks of transfers.

10 Turn on the starting air.

11 Check whether the throttle control lever is flexible, and after checking, put it in the 0 position.

12. Press the starting valve to flush the car, 13. When flushing, pay attention to whether a large amount of oil and water is discharged from the dynamometer valve.

14. After the car is completed, close the power valve.

2. Initiation. 1 Turn the load limiting knob to the position of 6.

2 Press the start valve and let go of the fire.

3. Check the oil pressure and water pressure.

4 Turn the load limiting knob to the maximum position.

3. Normal operation.

1. Check the oil level regularly.

2. Pay attention to the pressure and temperature, and adjust if necessary.

3. Pay attention to whether there is air leakage, water leakage, oil leakage and other phenomena everywhere.

4 Maintain the oil level of the daily oil tank.

4. Parking. 1 Deloading.

2 Slow down a little.

3 After a few minutes of no-load operation, turn the load limiting knob to the 0 position.

4. Open the dynamometer valve of each cylinder and transfer the car for several weeks.

1) Check the switches, the position of the knife switch is correct, and the interlock switch meets the requirements of the operation mode.

2) Check that the fuses are installed well and the power supply is normal.

3) Check that the voltage of the 24V battery is normal and the charger is running normally.

4) There is no oil leakage in the Yuchai generator set, the oil level of the diesel generator tank is normal, and the oil valve is open.

5) The outlet control switch of the diesel generator shall not be operated manually under any circumstances.

6) After each start and stop of the diesel generator, the self-start screen return button will be reset once.

7) During the operation of the diesel generator, someone monitors the operation of the diesel generator on site and meets the specified requirements.

8) When the 400V factory bus loses power, if the diesel generator does not start itself, it is allowed to start manually once, but the starting time of each time shall not exceed 15 seconds.

9) After the 400V factory bus loses power and the diesel generator starts normally, if the power switch from the diesel generator to the security section is not closed, it should be snapped once after confirming that the working power supply is opened.

10) Diesel generator fire extinguishing equipment should be complete.

1) On-site operation of the generator set. The operator starts, closes, regulates speed, opens, and stops the generator set in the machine room. The vibration, noise, oil mist and exhaust gases generated by the operation of this type of generator set have adverse effects on the health of the operator.

2) compartment operation generator set, the machine room and the control room of this type of generator set are set separately, the operator starts the diesel generator set in the machine room in the operation room, regulates the speed, stops and other operations, and monitors the operating parameters of the unit, and implements centralized control of the auxiliary equipment in the machine room. Compartment operation improves the working environment for the operator.

3) Automatic generator set. After years of research by all relevant units, the automation of diesel generator sets can be unattended, including unit self-starting, automatic voltage regulation, automatic frequency regulation, load regulation, automatic merging, automatic increase or decrease of units according to the load size, automatic fault handling, automatic recording The printer group can be automatically started in 10-15s after the mains power interruption, replacing the mains power for power supply.

There are four major precautions in the basic operation specifications of diesel generator sets, which are the preparation before starting, the precautions for starting the unit, the precautions for unit operation, and the precautions for unit shutdown. (For reference only: (Fujian Yanan diesel generator set:.)

4000-080-999) Ya Xiaonan will answer for you).

1. First of all, we should pay attention to the preparation before the start of the unit, each time before starting the machine, we must check whether the cooling water or antifreeze in the diesel engine water tank is satisfied, if it is missing, it should be filled, pull out the oil ruler to check whether the lubricating oil is missing, if it is missing, it should be added to the specified 'static full' scale line, and then carefully check whether there is a hidden danger of failure in the parts of the fish, and if the fault is found, it should be eliminated in time before it can be started.

2. The unit can not start the diesel engine with load, the diesel engine should pay attention to the output air switch of the generator before starting, the ordinary generator set diesel engine must go through 3-5 minutes of idle operation after starting, the temperature is low in winter, the idle operation time should be appropriately extended for a few minutes, after the diesel engine starts, it is necessary to observe whether the oil pressure is normal and whether there is oil leakage, water leakage and other abnormal phenomena, (under normal circumstances, the oil pressure must be above) if abnormal is found, it should be stopped immediately for maintenance, If there is no abnormal phenomenon, the diesel engine speed is increased to the rated speed of 1500 rpm, at this time the generator display frequency is 50Hz, the voltage is 400V, you can close the output air switch and put it into use, the generator set is not allowed to run without load for a long time, if it is an automatic generator set, it does not need to idle operation, because the automatic unit is generally equipped with a water heater, so that the diesel engine cylinder block is always maintained at about 45 degrees, and the diesel engine can be powered normally within 8-15 seconds after starting.

3. Pay attention to observe the working state in operation, the generator set should be on duty in the work, and often pay attention to observe a series of faults that may occur, especially pay attention to the changes in important factors such as oil pressure, water temperature, oil temperature, voltage, frequency, etc., in addition, it is necessary to pay attention to having enough diesel, such as fuel interruption in operation, objectively causing load stop, which may lead to damage to the generator excitation control system and related components.

4. Finally, it is strictly forbidden to stop with load, before each shutdown, the load must be cut off step by step, and then the output air switch of the generator set must be turned off, and finally the diesel engine will be slowed down to idle for 3-5 minutes before stopping.

The general diesel generator is a diesel engine, which is based on a diesel engine driving a small synchronous motor through a spindle to generate electricity.

Precautions before starting the generator are:

1.Check that the oil level is within the standard range.

2.Check the tank for water.

3.Press the manual valve to exhaust the air in the engine until diesel oil flows out of the diesel oil return port.

4.Check if the diesel fuel is in the liquid level and is within the standard range.

5.Check whether the battery and wiring are in good condition, and whether the battery voltage is within the standard range.

6.Confirm that the battery switch is in the "on" state.

7.Check whether the generator outlet is in good condition and whether the mains power is switched to power generation (it is necessary to pay attention to manual switching, and some companies will automatically start the generator after the mains power failure).

Notes after startup:

1.If it is black smoke, it means that the diesel is not completely burned, the engine is faulty or in the idle state, and it should be switched to the normal state in time.

2.Check if the oil pressure and temperature are within the normal range.

3.Check to see if the water temperature is within the normal range.

4.Check whether the three-phase electric voltage is within the normal range and whether it is balanced.

5.Check whether the three-phase electrical frequency is 50Hz, not to adjust to 50Hz

6.Record the above into the generator switch log.

Precautions for shutting down the generator:

1.Confirm that the generator emergency stop switch is pressed.

2.Confirm that the battery switch is in the "off" state (mainly to disconnect the battery wiring to reduce the battery discharge amount and ensure that the battery is charged when it is started next time.)

3,。Confirm that the generator door is closed to prevent small animals and unrelated personnel from entering.

That's pretty much it.

How big is the voltage Whether there is a power loss and it starts and the call stops.

Depending on what load is connected, there are also special precautions during operation.

Do not disassemble the generator, there is high voltage electricity in it
