1. Inspect the periphery of the diesel generator
The periphery of the diesel generator should be inspected every day before starting the diesel generator. The inspection contents are as follows:
(1) Inspect the diesel generator Check whether there are wiping cloths, waste wires, pipe clamps, screws and other debris accumulated on the radiator to keep the diesel engine clean and tidy.
(2) Check the joints and sealing surfaces of the fuel system, cooling system, and lubrication system for leaks.
(3) Check whether the fan and safety shield are safe and reliable.
(4) Check the fastening condition of accessories.
(5) Check whether the electrical circuit connectors are loose and whether the wires are intact.
(6) Check whether the transmission belt is intact.
2. Check the fuel tank
Check the oil level of the fuel tank every day
3. Check the air filter
Check the air filter every day , pay attention to the deterioration of engine performance, especially in windy and sandy areas. If the engine appears to emit black smoke or reduce power after running for a period of time, first check the blockage of the air filter element (of course, check the spray condition of the oil nozzle at the same time, and ensure that the oil supply is advanced angle, etc.), once the air filter is clogged, do not use oil, water or other liquids to clean the filter element. Stop the machine immediately and replace the air filter element.
△ Note: After replacing the air filter element, ensure that both ends of the air filter are reliably sealed and there is no air leakage.
△ Note: Never start a diesel generator without an air filter (outside of a marine diesel engine). Otherwise, it will easily cause early wear of the diesel generator.
4. Check the engine oil level
Every day before starting the diesel generator or when it is stopped (at least 15 minutes after stopping), so that the engine oil has sufficient time to flow back to the oil pan. ) Check the engine oil level. The engine oil level and the engine oil level height should be between the upper mark (FULL) and the lower mark (ADD) on the dipstick. If the oil level is insufficient, add oil to nearly the high oil level mark.
△ Note: Never run the diesel generator when the oil level is lower than the low oil level. Otherwise, the performance of the diesel engine will deteriorate and even the diesel generator will be damaged. However, the oil level must not exceed the upper mark FULL
5. Check the oil level of the fuel injection pump governor
Every day before starting the diesel generator or when it is stopped (at least 15 seconds after stopping) minutes to allow sufficient time for the oil to flow back to the governor) Check the oil level. The filler port on the fuel injection pump is on the governor. The oil filler cap is integrated with the oil dipstick.
(1) Loosen the oil dipstick handle on the speed regulator and check the engine oil level. Add if necessary, up to the upper mark (high oil level mark).
△ Note: The engine oil flows into the fuel injection pump through the governor cavity and the bearing clearance, so the refueling process is relatively long.
(2) Tighten the oil dipstick handle until it feels tight.
6. Check coolant page
Check the diesel engine coolant every day before starting the diesel generator or when it is stopped.Cool the liquid level.
△ Warning: When the diesel generator is working, the coolant temperature is high and there is pressure, which can easily cause burns. The coolant level can be checked or added only after the diesel generator is stopped and the coolant temperature drops below 50°C.
△ Warning: The coolant contains alkaline preservatives. Avoid contact with skin and eyes to prevent injury.
(1) Before starting or after stopping the diesel generator, after the coolant temperature drops below 50°C, slowly unscrew the pressure cap (armpit cap) on the radiator or expansion tank to release Cooling system pressure.
(2) Remove the pressure cap and check the coolant level from the filling port or level inspection port. It should be within the upper and lower markings or meet the equipment manufacturer's regulations.
(3) Add if necessary. Add close to the upper engraved line or meet equipment manufacturer's specifications.
△ Note: When adding coolant, it should be injected slowly to prevent air blockage.
7. Check the electrolyte level
Some batteries are not for maintenance. You need to pay attention to the service life of the battery. For details, please refer to the instructions on the battery. When the service life expires, it must be replaced in time.
Some batteries require special rehydration fluid or distilled water, so the electrolyte level needs to be checked.
(1) Remove the stamped page every day and check the electrolyte level. The electrolyte level should be at the bottom of the filling port. If the liquid level is insufficient, it should be replenished as required.
(2) Install the armpit cover.
△ Note: Remember to use purified drinking water instead. Because pure water contains a variety of trace elements, it will have adverse effects on batteries.
8. Check the transmission belt
Visually inspect the transmission belt every day. Check the tape for crisscrossing cracks. Transverse cracks along the width of the tape are permitted. However, longitudinal (along the length of the tape) and transverse cracks are not allowed. The tape should also be replaced if it becomes worn or if material peels off.
9. Check the cooling fan
Visually check the fan every day for cracks, loose rivets, loose and bent blades and other defects. Make sure the fan is installed reliably. If necessary, tighten the fastening bolts or replace the damaged fan.
△ Warning: Damage to the fan blades may cause serious accidents that could cause personal injury. It is never allowed to drag or pry the fan, let alone use the fan to rotate the crankshaft of the diesel engine.
10. Check the fan tape tension and transmission tape tension
Fan tape tension
Check: Press down forcefully with your fingers on the center of the two belt pulleys ( Approximately 98N of force is applied); observe the pressing distance. The required distance should be 12~15mm. If it exceeds this range, adjustments are required.
Transmission belt tension
Check: Press down forcefully with your fingers on the center of the two pulleys (approximately 98N force); observe the distance of the press. The required distance should be 8~12mm. If it exceeds this range, adjustments are required.
