The invention provides a fire pump, and relates to the technical field of fire fighting facilities. The fire pump solves the technical problems in the prior art. The fire pump comprises a shell, a gear drive structure, a fire pump main shaft and a planet rotor structure. The planet rotor structure, the fire pump main shaft and the gear drive structure are located in the shell, the shell is provided with a water outlet and a water inlet, a pumping cavity is formed in the shell, the planet rotor structure is located in the pumping cavity, and the pumping cavity is provided with a first port and a second port. The fire pump main shaft can drive the planet rotor structure to rotate in the pumping cavity through the gear drive structure, and in the rotating process of the planet rotor structure, liquid can be sucked from the water inlet through the second port and then output from the water outlet through the first port. The drive efficiency of the gear drive structure is improved; the hydraulic loss is small when the planet rotor structure rotates, and the pumping efficiency is high.
Description
technical field [0001] The invention relates to the technical field of fire-fighting facilities, in particular to a fire-fighting pump. Background technique [0002] As the name implies, fire pumps are used in fire fighting, which are divided into different types according to different classification methods. They are mainly used for fire fighting vehicle fire pumps, and can also be used for industrial and urban water supply and drainage, high-rise buildings, long-distance water supply, and heating. , bathroom, boiler cold and warm water cycle pressurized air-conditioning refrigeration system water delivery and equipment matching, etc., the current main domestic fire truck water pumps are BS30, BD50 and BD70. A fire pump with a rated pressure not greater than 1.6MPa is called a low-pressure fire pump, a fire pump with a rated pressure between 1.8MPa and 3.0MPa is called a medium-pressure fire pump, and a fire pump with a rated pressure not less than 4.0MPa is called a high-p...
