Basic types and characteristics of diesel engine fire pumps

The diesel engine fire pump set adopts ISW pump.
1. The pump is the horizontal structure, the inlet and outlet are the same in diameter, and lying in the same center line, which can be installed in the pipeline as valve, the floor space needed is small, if the protection cover is added, it can be put in the open air;
2. The impeller is installed on the major axis of the motor directly, the axial is short in size, the structure is compact, can calibrate radial and axial load that produced by pump rounding effectively, thus guaranteed the pump operating steadily, vibration, and low noise;
3. The axle seal adopts machinery seal or machinery seal sets, uses imported titanium alloy sealed ring, medium-sized high-temperature resistance machinery seal and adopts the hard alloy material, wear-resisting seal, which can lengthen the life of machinery seal effectively;
4. It is convenient to install and overhaul, no need to dismantle or move pipeline system; just lifting off pump conjunction flat nut can take all rotor parts out;
5. Can choose series or parallel operation according to your requirements for flow and lift;
6. Can be installed horizontally according to the pipeline system requirement.

All places need to be equipped with fire-fighting facilities, and fire pumps are the water intake equipment for fire-fighting facilities. At least one or two fire pumps are equipped. Our commonly used fire pumps are electric fire pumps and diesel engine fire pumps. The difference between them is that electric fire pumps require power systems. 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.

The diesel engine fire pump has stable performance, high efficiency, compact structure, low vibration and high pressure resistance of the pump body.
