Abstract

The invention relates to the technical field of fire fighting, and particularly discloses a movable-type high-pressure fire fighting pump system. The system comprises a movable-type ground fixing device, a water inlet pipe and a fire fighting water monitor, wherein a high-speed pump and a fuel gas turbine device are fixedly installed on the movable-type ground fixing device; the inlet of the high-speed pump is connected with a water inlet; the outlet of the high-speed pump is connected with the fire fighting water monitor; the shaft of the high-speed pump is connected with that of the fuel gas turbine device; and a fuel storage box is fixed on the movable-type ground fixing device, and is connected with the fuel gas turbine device through a fuel outlet pipe. The system can be used for driving the high-pressure pump through the fuel gas turbine device, and expanding the motive power source of a fire fighting pump; and meanwhile, the system has fuels, can take water directly from a fire hydrant, is high in lift, is small in volume, has good maneuverability, can reach different positions of a fire engine, and can be used for remedying the fire extinguishment height of the existing vehicle-mounted fire fighting system, achieving multi-azimuth fire fighting water supply of buildings with the height higher than 100m, and solving the maneuverability difficulty of large fire fighting equipment.

Description

technical field [0001] The invention belongs to the technical field of fire protection, and in particular relates to a mobile high-pressure fire pump system. Background technique [0002] In the field of fire protection, the limit parameters of the vehicle-mounted high-pressure fire pump are required to be that the outlet pressure is not less than 4.0MPa and the flow rate is not less than 10L / s. From the perspective of the relationship between flow and lift, the vehicle-mounted high-pressure fire pump is a small flow and high lift product. Similar products in the field of industrial applications often use multi-stage pumps, single-stage high-speed pumps or positive displacement pumps. Suppliers include well-known foreign companies and large domestic companies. The suppliers of multi-stage pumps include KSB of Germany, SULZER of Switzerland, EBOROA of Japan and their multinational companies, Shenyang Water Pump Factory, Chongqing Water Pump Factory, etc.; the suppliers of sin...
