Vertical Fire Pump

　　The vertical fire pump consists of a motor and a pump unit, with the pump and motor coaxially aligned. The pump structure includes components such as the pump body, impeller, pump cover, and mechanical seal. The pump inlet and outlet are positioned on the same horizontal axis with identical diameter specifications, enabling extremely convenient installation and removal while occupying minimal floor space. The pump features an installation base for easy mounting and enhanced operational stability. The mechanical seal ensures reliable sealing with zero leakage. Axial forces are balanced by a balance ring integrated into the impeller. The inlet and outlet flanges are designed for 1.6MPa pressure, facilitating pipeline compatibility.

　　The XBD-L vertical single-stage, single-suction firefighting pressure-stabilizing pump comprises a motor and pump assembly. The motor is a Y-type three-phase asynchronous motor. The pump and motor are connected via a coupling, forming a rigid joint that requires no alignment during operation. The pump comprises stator and rotor sections. The stator includes the inlet casing, intermediate casing, guide vanes, discharge casing, and stuffing box housing. To prevent stator wear, components like seal rings and balancing sleeves are installed and can be replaced with spare parts when worn. The rotor section consists of the shaft, intermediate impeller, and balancing drum. The lower end of the rotor features water-lubricated bearings, while the upper section employs angular contact ball bearings. The balance drum absorbs the majority of the pump's axial force, with the remaining residual downward axial force borne by the angular contact ball bearings. The mating surfaces of the inlet casing, intermediate casing, and discharge casing achieve sealing through tensioning with paper gaskets, allowing users to select options as needed.
