Portable Hand Carry Diesel Engine Fire Pump Set

Since the diesel engine fire pump can easily change the lift, the efficiency of the device can also be greatly improved. Diesel engine fire pumps can work in different working media and media with different temperatures by changing the material or coating with a special protective layer. The diesel engine fire pump occupies less floor space, and the diesel engine fire pump has less vibration and noise.

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 is to use the airflow coming in from the machine during movement 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 a cooling medium to take away the heat of the high-temperature parts of the diesel fire pump engine to ensure the normal working temperature of the engine.

    When the diesel engine mobile pump truck is working, the diesel engine water pump relies on the high-speed rotating impeller, and the liquid obtains energy under the action of inertial centrifugal force to increase the pressure. Before the centrifugal pump works, the pump body and the inlet pipeline must be filled with liquid medium to prevent cavitation. When the impeller rotates rapidly, the blades make the medium rotate quickly, and the rotating medium flies out of the impeller under the action of centrifugal force. After the water in the pump is thrown out, the central part of the impeller forms a vacuum area. While continuously inhaling liquid, it continuously gives the inhaled liquid a certain amount of energy to discharge the liquid. The diesel engine water pump just works continuously like this.
