企业特殊行业经营资质信息公示
点击图片查看原图- 结构可靠：转子刚性好、转动惯量小，启动电流低，对电网冲击小；轴承拆装方便，避免过热损伤，保障长期稳定运行。
- 高效节能：通过CFD流体力学计算优化叶轮与壳体匹配，效率曲线平坦宽广，适应多种工况需求。
- 应用广泛：适用于输送清水或物理化学性质类似水的液体，最高温度一般不超过80℃，进口压力不超0.2MPa。
- 安装维护简便：外形尺寸紧凑，节省空间；轴封位于低压区，密封更可靠；支持填料密封或机械密封，可根据现场需求选配。
在实际使用中，需注意以下几点：
- 启动前必须灌泵排气，严禁干运转；
- 运行时轴承温度不应超过75℃（环境温度高时上限可适度提高）；
- 长期停用应排空泵内积水并做防锈处理；
- 高海拔地区需重新校核电机功率与汽蚀余量。
Product Overview:
The Kaiquan KQSN150-M4/310 is a high-efficiency, single-stage, double-suction horizontal centrifugal pump designed for large-flow and low-head industrial applications. As a split-case (mid-open) pump, it features a robust structure, superior hydraulic performance, and ease of maintenance, making it an ideal choice for HVAC systems, industrial water circulation, and municipal water supply projects.
Key Features & Advantages:
Superior Hydraulic Design: Optimized impeller and volute casing design ensure high efficiency, energy savings, and a flat performance curve adaptable to various working conditions.
Robust & Stable Operation: The double-suction structure balances axial thrust, ensuring smooth operation with low vibration and noise. The rigid rotor design minimizes deflection and extends seal life.
Easy Maintenance: The horizontally split casing allows for easy access to internal components (impeller, shaft, bearings) without dismantling the suction and discharge piping, significantly reducing downtime.
Reliable Sealing: Equipped with a high-quality mechanical seal or packing seal located in the low-pressure area, effectively preventing leaks and ensuring long-term reliability.
Space-Saving: Compact footprint design helps save valuable installation space in pump rooms.
