Features and principles of diesel generator set emergency fire pump

Diesel emergency fire pumps are suitable for pressurized water supply in fire pipelines. Or it is used to transport clear water or other liquids with physical and chemical properties similar to clear water for pressurization. The temperature of the medium does not exceed 80°C. It is suitable for industrial and urban water supply and drainage, pressurized water supply for high-rise buildings, garden sprinkler irrigation, long-distance water supply, heating, bathroom and other cold and hot water cycle pressurization and equipment matching.

Diesel emergency fire pumps can be divided into horizontal, single-suction, multi-stage, segmented structures, and are the latest series of energy-saving products. Its performance parameters and technical indicators are in line with relevant standards, and it has significant advantages such as high efficiency, low operating noise, good anti-cavitation performance, reasonable structure, and long service life.

Diesel emergency fire pumps can be used to transport clear water without solid particles and liquids with similar physical and chemical properties to water. It is mainly used in fire protection system, heating, bathroom, boiler cold and hot water cycle pressurization, water supply of air conditioning and refrigeration system, equipment matching and other occasions.

    Generally speaking, we recommend that where natural ventilation is used to install diesel engine fire pumps, there must be vents and exhaust ports of sufficient size, and the position of the vents ensures that there is enough fresh air to supply the diesel engine for combustion within the temperature limit. Of course, the water supply radiator can also be used to take away the heat of the circulating cooling water and the heat emitted from the surface of the unit. If the space cannot meet the requirements of natural ventilation and cannot effectively dissipate heat, it is recommended that you adopt forced ventilation, install an intake fan and an exhaust fan at the vent, and choose a location that can provide enough cold air for the diesel engine and take away the machine room hot air inside. Generally speaking, the air intake of the unit should be 6-7 times that of the diesel engine. Only in this way can normal ventilation be ensured and the operating efficiency of the equipment can be improved.

    In addition, it must be fixed firmly so that the entire unit can be supported to ensure that the unit is in a horizontal state and absorb vibration. Generally speaking, the foundation of the unit adopts a concrete structure. The length and width are 150-250mm on one side of the length and width of the unit chassis, and the depth is 300-600mm. The height of the anchor bolts should be about twice the bolt diameter. And there should be a 750mm channel on both sides and front of the unit to facilitate the operator’s inspection and general maintenance.
