Routine inspection and management of diesel engine fire pump | ZJBetter
In order to improve the ability to respond to fire signals of the diesel fire pump, it is better to inspect once a week. Taking into account the water hammer effect and the characteristics of the diesel engine, we should start the diesel engine at low speed during the inspection, and then slowly accelerate to the speed required for fire protection - 1500r/min-3000r/min. When the water temperature and oil temperature reach 60 °C, it can be gradually decelerated, but it needs to run at idle speed (300~750r/min) for 2~3min before stopping, so as to avoid the supercharger bearing seizing due to overheating of the supercharger during sudden stop!
After parking, make sure to adjust the speed to 1500r/min-3000r/min for fire protection.
Because the inspection process of diesel fire pump is more complicated, if there is no special request from customers, we will not consider automatic inspection in the design process. We suggest that users use manual inspection mode!
To ensure the reliability of the entire control system, rugularly daily management is inseparable. Although the diesel fire pump has a high degree of automation, but the human damage factors cause it to lose function frequently! The components are damaged or lost, the parameters of the time relay and the charger are incorrectly modified, etc., the user has reflected! The key to the room must be managed by a special person, and it is necessary to regularly check whether the parts of the equipment are lost or damaged by other factors, and whether the parameters of each component are scientific and reasonable.
