美国大力公司始创于1908年,是一家全套生产消防车、消防泵、各种移动灭火系统、辅助装备和各种消防器材、保安器材等的专业企业。特别是该公司开发的全自动压缩空气A类泡沫灭火系统,其独有的设计,强大的灭火功能,赢得了广泛的赞誉。1大力系列消防水泵大力系列消防水泵均采用取力器驱动,出入口为轴向水平吸人,径向垂直中心输出,出入口法兰可承受较大的管口载荷并具有相同的压力等级。该系列产品采用径向多角度安装方式,有两种旋向可供选择。它较大的法兰口径保证了较低的流速,同时叶轮和泵体的设计保证了低噪音,且U型密封环的结构降低了水的损失。此外,该产品的轴承、齿轮采用油浴润滑,齿轮箱的冷却分自冷、空冷(没有散热片)、和水冷三种形式;轴向力采用带有平衡孔的前后口环平衡;密封采用注射式填料,也可提供机械密封。
The American company was founded in 1908. It is a professional enterprise that produces fire engines, fire pumps, various mobile fire extinguishing systems, auxiliary equipment, various fire-fighting equipment, and security equipment. In particular, the company developed a fully automatic compressed air Class A foam fire extinguishing system, its unique design, powerful fire fighting features, has won wide acclaim. 1 Strong series Fire pump series The fire pump series are all driven by a power take-off device. The inlet and outlet are horizontally inhaled and the radial vertical center is output. The inlet and outlet flanges can bear larger nozzle loads and have the same pressure level. This series of products uses radial multi-angle installation, there are two kinds of rotation direction to choose from. Its large flange diameter ensures a low flow rate, while the design of the impeller and pump body ensures low noise, and the structure of the U-shaped seal ring reduces water loss. In addition, the bearings and gears of this product are lubricated with an oil bath. The cooling of the gearbox is divided into three forms: cold, air-cooled (without heat sink), and water-cooled; the axial force is balanced with front and rear mouth rings; the seal is used Injectable fillers can also provide mechanical seals.
