PTW型卧式离心泵

特点: Features PTW型帕特卧式离心泵是在IS型单级离心式清水泵以及ISG型管道式离心泵的基础上进行设计制造而成； Designed on the basic of IS single stage centrifugal. 本系列泵在原IS泵的基础上对其结构进行了大胆的改进设计,同时吸取了ISG型泵的优点,性能参数采用了ISO2858标准,产品质量执行JB/T53062-93标准,其经济技术性能指标达到国内同类产品先进水平； Take advantage of virtues of ISG pump, performance date according to ISO2858 standard and product quality performs JB/T53062-93 standard so the technical performance is advanced in domestic congener products. PTW型泵由于电机与泵直联,简化了中间传动的结构,增强了运行的平稳性,并比普通卧式泵占地面积减少了30%,轴封采用硬质合金机械密封,寿命长,且具有噪音低,维修方便,震动小等优点。 The motor and pump are joined directly without transmission parts. So they operate smoothly. Compared with common horizontal pump. PTW series can decrease 30 percent floor space. The shaft seal is made with hard alloy mechanical seal whose working life is long-Besides, the pump features low noise, convenient maintenance and light shake. 用途 Applications 适用于工业、城市给水、高层建筑供水 Water supply in industry, cities and high-rises 消防管道增压 Fire fighting pipeline pressurizing 冷暖空调冷热水循环 Cold and hot water circulation in air-condition 远距离输水 Transport water from far away 生产工艺循环增压输送、并适用于各种给排水设备、锅炉等设备的配套使用 Pressurizing transport in industrial circulating system, and all kinds of water supply equipments, boiler etc. 工作条件：Operating Conditions 流量范围 Capacity range:2～1800m3/h; 扬程范围 Head range: 5～150m; 泵系统最高工作压力≦1.6MPa，即吸入口压力+泵扬程≦1.6MPa System Max: working pressure should not be greater than 1.6MPa, namely pressure in suction add to head of head should not be greater than 1.6MPa. 介质温度 Liquid temperature:-15℃﹤T﹤+105℃ 周围环境温度 Ambient temperature: ≦40℃ 电机防护等级 Motor＇s degree of protection:IP54或IP44； 电机绝缘等级 Motor＇s class of insulation: B级或F级
