Applicable scene
Suitable for mines with long-term self-generation, construction temporary power, standby generator sets, or long unattended periods.
The first step in daily generator-set maintenance is not replacing parts, but helping site staff confirm every day whether the generator set can safely carry load. In remote mines, construction sites, and long-running self-generation sites, many faults first appear as low fluid levels, odors, abnormal sounds, oil or water leaks, controller alarms, or weak battery starting.
The pre-startup inspection should be short, fixed, and executable. Don't make it a long form that no one wants to fill out, but form inspection actions that can be completed in every shift around oil, fuel, battery, belts, cooling, controllers and the on-site environment.
Generator set appearance and surrounding environment
- Check whether there is standing water, mud, debris, obstructions, or temporarily stored materials around the generator set.
- Check for signs of oil, water, or fluid leaks around the base of the generator set, fuel lines, filters, coolant lines, and radiator or water tank.
- Confirm that the air inlet, exhaust and smoke exhaust channels are not blocked by canvas, wooden boards, mineral powder or construction materials.
Fluids and fuel
- Check whether the oil level is within the normal range and whether the oil color and smell are abnormal.
- Check the coolant level, expansion tank, hoses and clamps to confirm there is no obvious lack of fluid or leakage.
- Confirm that the fuel in the daily fuel tank is sufficient to cover the operation of this shift, and observe whether there is any risk of water or sedimentation at the bottom of the fuel tank.
Start and control system
- Check whether the controller has unprocessed alarms, shutdown records or low voltage prompts.
- Check whether the battery terminals are loose or corroded, and whether the voltage is obviously low before starting.
- Confirm that emergency stop buttons, circuit breaker positions, ATS status, and manual/automatic modes comply with the day's operating plan.
