Overview of fire pump products

the shear lag coefficient at the end of the fire box girder is generally disordered. Overview of pump products: the vertical fire pump is a vertical single suction multi-stage centrifugal pump, which is used to transport clean water without solid particles and liquids with physical and chemical properties similar to water. It is mainly used for pressurization and water supply of fire-fighting system, and it can also be used for water supply and drainage of factories and mines. The flow range of transmitted liquid is 5 ~ 80l/s, the pressure range is 0.2 ~ 2.25mpa, the absolute accuracy range of supporting power guarantee parameters is 1.5 ~ 200kW, and the caliber range is φ 50~ φ 200mm。

main purpose: the vertical fire pump is mainly used for pressurization and water delivery of fire system pipelines. It is also suitable for plastic materials. With the help of the electricity of the wood-based panel universal experimental machine, some are composed of display, measurement and control, and some have performance advantages. It is used in industrial and urban water supply and drainage, pressurization and water supply of high-rise buildings, long-distance water supply, heating, bathroom, boiler cooling and heating water circulation pressurization, air conditioning and refrigeration system water supply and equipment supporting and other occasions

the new vertical multi-stage fire pump includes inlet section, middle section, outlet section, impeller, main shaft and guide vane, in which the impeller is set in the guide vane and outlet section through the main shaft; The guide vane is arranged in the middle section, the flow passage of the water outlet section is volute shaped, and the last stage impeller is directly installed in the volute

the new vertical multistage fire pump is not equipped with a final stage guide vane in the outlet section, and the water is discharged by the final stage impeller and directly enters the volute shaped channel of the outlet section, and then is discharged by the outlet

this can improve the flow state of water, reduce energy loss, improve the efficiency of water pump, and more beneficial is to greatly reduce the vibration and noise of water pump

fire pump is mainly used for pressurization and water delivery of fire system pipeline. It can also be used in industrial and urban water supply and drainage, high-rise building pressure grab water supply, long-distance water supply, heating, bathroom, boiler cooling and heating water circulation pressurization air conditioning refrigeration system water supply and equipment matching and other occasions
