XBD-HY(HL) Series Vertical Constant Pressure Fire-Fighting Pump

产品概述
    XBD-HY(HL)系列立式恒压消防泵是我公司根据市场需求而研制的适用于高层建筑消防给水和生活供水的新产品，是可靠、高品质的消防专用泵。其性能、技术条件符合国家标准GB6245-2006《消防泵性能要求和试验方法》标准的要求。

    XBD-HY(HL)系列立式恒压消防泵具有变流稳压的特点，即在全流量范围内，扬程变化不大，泵从零流量到所需最大流量范围内的变化时，其扬程变化在5％范围内，且小流量或零流量时不超压，从而避免了普通离心泵在消防现场中小流量时超压而大流量时供不上水的现象。大大提高了灭火效率及消防设备和消防人员的安全可靠性。

    根据消防泵自身特点结合我公司情况，立式结构恒压消防泵电机功率≤75kW，卧式不限。泵叶轮为开式，轴向力小，无口环，防止了锈蚀咬死现象。泵体、泵盖采用铸铁，叶轮根据用户要求采用。

Product introduction
    XBD-HY(HL) series vertical constant pressure fire-fighting pump is a kind of new product researched and manufactured by our company according to market demand. Applicable to fire-fighting and living water supply in high-rise constructions, it belongs to a special fire-fighting pump with reliable and high-quality nature. The performance and technical conditions accord with the requirements of National Standard GB6245-2006 Performance Requirements and Testing Method of Firefighting Pump.
    XBD-HY(HL) series vertical constant pressure fire-fighting pump enjoys variable flow and stable pressure. That is to say, within the scope of total flow, the range does not have great changes; once the pump
changes from flow zero to the limit within the needed maximum flow, the range change is within the scope of 5% and the pressure will not exceed in case of small flow or flow zero. All these characteristics have avoided the phenomenon of excessive pressure of ordinary centrifugal pump in medium and small flow but supply shortage in large flow and greatly upgraded the safety and reliability for fire-fighting efficiency, firefighting equipment and personnel.
    According to the characteristics in the fire-fighting pump and by conditions of our company, the motor power of vertical constant pressure fire-fighting pump ≤75kW besides of horizontal pump. The pump impeller is open type strutural with small axial force and without rings which have prevented the rusting and seizure. Cast iron is adopted for pump body and pump cover, blade is according to comsumer's require.

产品用途
XBD-HY(HL)系列立式恒压消防泵主要适用于工业、民用建筑物消防系统(消防栓灭火系统、自动喷淋系统和水雾灭火系统)的给水，另外也可用于消防和生活(生产)共用的给水系统及建筑、市政、工矿、锅炉给水等各种场合。

Product application
XBD-HY(HL) series vertical constant pressure fire-fighting pump is mainly applicable to the water supply of fire-fighting systems (firefighting hydrant system, automatic spraying system and water mist firefighting system) in the industrial and civil constructions. Furthermore, it can also be adopted for shared fire-fighting and living (production) water supply systems and the water supply systems in constructions,municipalities, mines and boilers.
