First, the product overview XBD-ISG vertical multistage fire pump is my company in the original DFG vertical single-stage centrifugal pump on the basis of GB6245-1998 "fire pump performance requirements and test methods" standard requirements improved. Mainly used for fire hydrant water supply, sprinkler system water supply, other fire fighting system water supply, other occasions, the transfer of clean liquid. Structure Features of XBD-ISG Vertical Multi-stage Fire Pump II. Product Features 1.Efficient and energy-saving: Adopt CFD to calculate fluid dynamics, analyze and calculate the pressure distribution and velocity distribution in the pump, optimize the flow passage design of the pump to ensure high efficiency of the pump The hydraulic shape of the line, improve the efficiency of the pump. 2, easy installation and maintenance: vertical pipe structure, the import and export of the pump can be installed in the pipeline as any position and any direction, installation and maintenance is very convenient. 3, smooth operation, safe and reliable: direct connection between the motor and the pump, simplifying the intermediate transmission structure and enhance the smooth operation, so that the unit running smoothly, safe and reliable. 4, stainless steel sleeve: shaft sealing position is relatively easy to rust place. Directly connected pump shaft once corroded, can easily lead to machine seal seal failure. Pump fitted here with stainless steel sleeve, to avoid corrosion occurred, improve the shaft life, reduce operating and maintenance costs. 5, Bearing: pump equipped with motor, Y (Y2) 280 below the shaft end bearings (including Y180 the following blade end bearings) with closed bearings, normal use, maintenance-free motor bearings. 6, mechanical seal: The mechanical seal base generally use rubber bellows structure, the seal on the shaft of the traditional mechanical seal from O-ring line seal to two pieces of rubber seal to improve the sealing effect. Third, the working conditions Flow: 0.56 ~ 300L / s Rated pressure: 0.5 ~ 1.3MPa Maximum working pressure of the system: ≤1.6MPa Working temperature: -15 ℃ ~ +105 ℃ Supporting motor: Insulation class: Class B or Class F Protection class: IP44 or IP54 Ambient temperature: ≤ + 40 ℃ Motor type: Y or Y2
