Before starting the electric motor fire pump set, the inspection work is indispensable. Check the condition of the power supply and motor, whether the water volume of the reservoir is sufficient, and whether the water inlet and outlet are normal. The inspection is normal and then starts; after the fire pump is started, attention should be paid to the vibration and temperature rise. It is necessary to set the maintenance time period to ensure the stable performance of the fire pump. According to the needs of system operation control and maintenance management, the electrical control cabinet of the fire pump mainly has the functions of starting and stopping the pump, switching between the main and standby pumps, manual automatic switching, dual power switching, patrol inspection, Protection, feedback mechanical emergency start and other functions.

The jockey pump of the jockey fire water supply system must be kept running at ordinary times to maintain the pressure of the pipe network. When a fire occurs, it should still be able to run for a period of time until the main fire pump is started. It must be set according to the main and standby pumps. pressure pump. Due to the need for the stabilizing pump to keep running, energy is wasted, and the stabilizing pump is in working condition for a long time.

With the continuous development of society, people have higher requirements for the quality of life, and the safety of diesel engine fire pumps is more important. All places need to be equipped with fire-fighting facilities, and fire pumps are water intake equipment for fire-fighting facilities. A fire pump Our commonly used fire pumps are electric fire pumps and diesel engine fire pumps. The difference between them is that electric fire pumps need power system supply. In the event of a power failure, the diesel engine fire pump can be started at any time to make up for the original position of the electric fire pump.

1. The function of the diesel fire pump is very powerful. We can set the control time during use, such as: preheating, pre-lubricating or timing start. The use of high-tech has made some complicated and time-consuming things easier in the past. The preheating setting greatly reduces the preparation time for rescue, allowing firefighters to rescue the first time. In the face of disasters, time is money and time. is life.
2. The head and flow can be controlled by adjusting the speed of the engine, and the height and size of the water flow become easier to control. When the nozzle is in a stable state, by controlling the engine, we can accurately spray the water source at the fire point to extinguish the fire, which also reduces the difficulty of rescue for firefighters.
