The casing of the diesel engine fire pump constitutes the working chamber of the pump. The impeller, shaft and rolling bearing are the rotors of the pump. Suspension bearing parts The supporting parts support the rotor parts of the pump, and the rolling bearings are subjected to the radial and axial forces of the pump. In order to balance the axial force of the diesel engine fire pump, most pumps have sealing rings at the front and rear of the impeller, and a balance hole on the back cover of the impeller. Because some pumps have little axial force, there is no seal on the back of the impeller. ring and balance hole. The axial sealing ring of the diesel engine fire pump is composed of packing gland, packing ring and packing to prevent air intake or large water leakage.

Diesel engine fire pumps can easily change the head, so that the efficiency of the device can also be greatly improved. Diesel engine fire pumps can be adapted to work in different working media and media at different temperatures by changing the material or coating with a special protective layer. The diesel engine fire pump occupies less area, and the vibration and noise of the diesel engine fire pump is relatively small.

       The operation of the Fire Pump Set

     Operation of diesel engine fire pump

     Diesel engine fire pump operation:Start, Stop and Run of the Equipment

Start: first make sure of the correct rotatingdirection of the fire fighting pump and the inlet valve is as N.O and outletvalve N.C. Before the pipe network starts with no water. After no error is found, start the fire-fighting pump and, when the pump gets stable run, gradually open the outlet valve and adjust it to the work condition point for the pump to run. The outlet valve is N.O. when the network is filled with water at usual.
Run: when the pump gets a normal run, check the shaft seal and the bearing to see how it works. Theleakage for themechanical seal should not be over 3 drops/min and for the stuffing seal should be dot drop. The bearing’s temperature should not be over 75℃ and its temperature rise not over 35℃ Stop running for a checking case of an abnormal sound during the pump’s run.
To stop, first close the outlet valve, then the diesel engine.

Since the operation of the electric water pump is inseparable from electricity, and the power supply is often cut off at the scene of a fire accident or the power supply is automatically closed due to the fire, even if we are equipped with a dual power supply switching device, it is really impossible to ensure that the power grid must be normal when the fire alarm signal comes.
Therefore, starting and running a diesel engine fire pump completely disconnected from the grid becomes the preferred equipment for backup fire protection facilities! The driving power of diesel engine fire pumps is completely different from that of electric water pumps, so their daily protection and treatment are also different in many places! The characteristics of diesel engine fire pump: The biggest difference between diesel engine fire pump and electric water pump is that it has its own independent power supply system – storage battery. Therefore, the start and operation of diesel engine fire pump can be completely separated from the mains.

The main heat dissipation methods of diesel engine fire pumps can be divided into two types: wind heat dissipation and water heat dissipation. According to the two heat dissipation principles, the water heat dissipation system dissipates heat evenly and has a good heat dissipation effect. The relative price is also relatively low, so most diesel fire pumps mainly use water for heat dissipation. Wind cooling is divided into two types: natural wind and forced wind. Natural wind uses the airflow coming in from the machine in motion to directly cool the cylinder head, cylinder block and other parts; The airflow at the place increases the cooling rate and area. The principle of water heat dissipation is to use water or antifreeze as the cooling medium to take away the heat of the high-temperature parts of the diesel engine fire pump engine to ensure the normal working temperature of the engine.
