How to maintain diesel engine fire pump
一、 Inspection before starting the diesel engine fire pump
1. Check whether the coolant level and fuel oil level of diesel engine fire pump are normal.
2. Whether the fasteners of diesel engine fire pump are safe.
3. Check whether the shaft seal of diesel engine fire pump is normal and whether it needs to be adjusted or replaced.
4. Whether the lubricating grease of diesel engine fire pump is sufficient.
5. Whether the grounding of diesel engine fire pump meets the requirements.
二、 Normal startup
1. Press the start button, and it can be started once under normal conditions. If the starting fails, the next starting can only be carried out after the starting armature is completely stationary.
2. If it fails to start for several times, check the starting, diesel engine, battery, connection, etc. before starting.
3. When the diesel engine fire pump operates normally, the pressure of the pump shall be checked in time. If the pressure of the pump is not reached, the repairman shall be informed in time.
三. shutdown
1. Press the stop lever until the flywheel stops or the instrument speed indicates zero.
四、 Maintenance of diesel engine fire pump set
1. According to the fire code, the unit must be operated at least once every 15 days and for at least 15 minutes to ensure that the diesel engine fire pump is in good condition at any time.
2. Regularly add lubricating oil to the gear surface to lubricate the bearing.
3. If the diesel engine fire pump is shut down for a long time, the water in the pump cavity shall be discharged to prevent the pump body and other components from freezing and cracking due to the low ambient temperature.
4. The daily maintenance of diesel engine fire pump shall be carried out in accordance with the maintenance regulations of diesel engine. Check whether the cooling water volume, oil volume, battery voltage, oil pressure gauge, thermometer, tachometer and other control devices are normal.
五、 Battery maintenance
1. Clean battery dirt. Use a wet cloth to wipe the dust, oil, white powder, etc. on the outside of the diesel generator bottle, the panel and the pile head (i.e. positive and negative poles), which are easy to cause leakage.
2. The battery of diesel engine fire pump must be charged correctly before long-term storage and use to ensure the normal capacity of the battery of diesel generator.
3. When the battery overheats during charging, it shall stop charging for a period of time.
4. After the battery is fully charged, it is necessary to stop charging immediately.
5. In order to avoid the diesel engine fire pump generator bottle starting at low temperature, in low temperature environment, the capacity of the diesel generator bottle can not be output normally, and long-term emission will lead to the failure (cracking or explosion) of the diesel generator battery.
6. It is forbidden to short circuit the two poles of the diesel engine pump battery.
