1. Check the oil level: Ensure that the oil level is above the lower end of the oil level gauge and add it to the upper limit.
2. Check the coolant: Ensure that the water level or antifreeze in the water tank is sufficient, and replenish it promptly if it is insufficient.
3. Check fuel level: Check if there is sufficient fuel in the fuel tank, if the fuel supply and return switches are open, and if there is any oil leakage in the fuel pipeline.
4. Check the lubricating oil: Confirm whether the lubricating oil has reached the specified filling line.
5. Check battery voltage: Check if the voltage of the starting battery is normal and ensure that the battery is fully charged.
6. Check external connections: Check the unit and load connection circuits to ensure that the generator output and control lines are not damaged or loose.
7. Environmental temperature: When starting in a low-temperature environment, auxiliary equipment such as air preheaters, fuel heaters, etc. should be used to ensure that the temperature of the intake air, fuel, oil, and coolant is maintained at a high temperature.
8. Preheating before starting: When starting in winter, run at low speed for 3-5 minutes to increase the temperature of the diesel engine body and check the working condition of the lubricating oil.
9. Check the filter element: Regularly replace the air filter element, diesel filter element, and oil filter element to ensure that the filter element is working properly.
The specific operating steps before starting Weichai diesel generator set are as follows:
1. Manual start: Ensure that the alarm system is working properly, set the control switch to manual mode (MAN), and the diesel generator set will start autonomously.
2. Automatic start: Switch the control switch to automatic mode (AUTO) and ensure that the power automatic switch (ATS) is also in the automatic position. When the mains power is interrupted, ATS will send a start signal to the generator control system.
Special precautions for starting Weichai diesel generator sets in winter:
1. Cooling water treatment: After winter operation, if parked outdoors and the local temperature is below 4 degrees, the cooling water in the cooling water tank should be drained to prevent volume expansion and damage to the radiator of the cooling water tank.
2. Auxiliary start-up method: During winter start-up, corresponding auxiliary methods should be used, such as using air preheaters, fuel heaters, etc., to increase the body temperature.
3. Low speed operation: After starting, run at low speed for 3-5 minutes to increase the overall temperature of the diesel engine and check the working condition of the lubricating oil.
Following these precautions and operating steps can ensure the smooth start-up and normal operation of Weichai diesel generator sets.
