Preparation before the start of the diesel generator set

Diesel generator sets are a good helper for backup power, and are spare and emergency equipment to alleviate power shortages. The user can start normally when the unit is in use, and it is necessary to prepare the generator set before starting.

First of all, before starting the diesel generator set, it is necessary to check whether the diesel engine parts are normal, and whether the connection of each accessory is reliable. For example, all the joints of the intake pipe and the cooling water pipe must be tightened; then, check whether the amount of engine coolant is sufficient. If it is insufficient, it should be filled up; check whether the lubricating oil level in the oil pan of the generator set is at the specified position; check whether the diesel fuel in the fuel tank is enough, whether the connection of each line of the starting system is correct, and whether the battery is fully charged.

After performing a series of checks, the other thing to do is to use the hand pump on the fuel pump to inject fuel into the fuel system and loosen the bleed screw on the fuel pump (or unscrew the fuel filter). The bleed screw plug on the upper part to remove the air in the fuel system until the fuel flowing out from the venting area is free of air bubbles. Then tighten the bleeder screw or the bleed screw plug, and then continue to pump the oil by hand pump until the return pipe has oil return, and then tighten the hand pump.

For new, overhauled engines or diesel generator sets that have been unused for more than 5 days, the crankshaft should be turned 3 to 5 revolutions before starting. For turbocharged engines, the oil inlet pipe must be removed first, and 50-60 ml of clean lubricating oil is added to lubricate the bearings. Then replace the oil inlet pipe.

It is emphasized here that for those diesel generator sets that are normally parked and used only for emergency use, in order to ensure timely start-up, during the parking period, the test run should be started every 3~5 days, and the water temperature and oil temperature should be reached. Above 60 ° C, while ensuring that the room temperature of the equipment room is not lower than 10 ° C.
