Vertical fire pump is a vertical single-suction multistage centrifugal pump for conveying solid particles of clean water and the physical and chemical properties similar to water for liquid purposes. Mainly used for fire-fighting system pressurized water, can also be used for water supply and drainage factories. Liquid flow rate range of 5 ~ 80L / s, the pressure range of 0.2 ~ 2.25MPa, supporting the power range of 1.5 ~ 200kW, caliber range of φ50 ~ φ200mm. Main purpose: Vertical fire pump is mainly used for fire-fighting system pipeline pressurized water. Can also be applied to industrial and urban water supply and drainage, high-rise building pressurized water supply, long-distance water supply, heating, bathroom, boilers, heating and cooling water circulation pressurized air conditioning and cooling system water supply and equipment and other occasions. The new vertical multistage fire pump comprises a water inlet section, a middle section, a water outlet section, an impeller, a main shaft and a guide vane, wherein the impeller is arranged in the guide vane and the water outlet section through a main shaft; the guide vane is arranged in the middle section, Sections of the flow channel for the volute, the final impeller mounted directly in the volute. The new vertical multistage fire pump in the water is not set at the end of the guide vane, water from the final stage after the impeller directly into the discharge section of the volute-shaped runner, and then discharged from the outlet. This can improve the flow of water, reduce energy loss, improve pump efficiency, more beneficial to greatly reduce the vibration and noise of the pump. Fire pump is mainly used for fire-fighting system pipeline pressurized water. Can also be applied to industrial and urban water supply and drainage, high-rise building to seize pressure and water, long-distance water supply, heating, bathroom, boilers, heating and cooling water circulation air conditioning and refrigeration systems, water supply and equipment and other occasions.
