【中：上海凯泉 KQDP 不锈钢多级泵专业指南】上海凯泉（Shanghai Kaiquan）KQDP 系列KQDP32-5-71是专为高要求供水环境设计的立式多级离心泵。其过流部件采用不锈钢冲压焊接工艺，水力流道极度平滑，不仅效***且***了二次污染，是市政二次供水、工业清洗及锅炉给水的核心设备。

安装核心规范：

1. 基础稳固： 泵组必须垂直安装在坚固的混凝土基础上，并确保地脚螺栓紧固，防止因重心偏移产生的细微振动。

2. 管路无应力： 进出口管路必须配备独立支撑，严禁泵体承载管路重量，防止机械密封受损或法兰开裂。

3. 进水监测： 安装时建议配套真空表和压力表，吸入管径必须大于泵入口径，防止气蚀产生。

维护与故障预防：

严禁干转： 启动前必须注满液体并排气。机械密封依赖液体冷却，干运行会导致陶瓷端面瞬间爆裂。

• 密封更换： 若泵头出现渗漏，请使用原厂 KQDP 专用机封，安装时严禁在密封面涂抹油脂，以防密封装配不到位。

• 轴承保护： 定期检查电机轴承异响。对于常备泵，建议每月切换运行，保持轴系润滑活性。

[EN: Shanghai Kaiquan KQDP Stainless Steel Multistage Pump Guide]Shanghai Kaiquan&＃39;s KQDP series KQDP32-5-71features vertical multistage centrifugal pumps designed for high-purity water delivery. With stainless steel (SS304/316L) hydraulic components, it offers superior corrosion resistance and energy efficiency, exceeding national standards for municipal and industrial applications.

Key Installation Standards:

1. Verticality & Foundation: Ensure the pump is mounted on a level, solid concrete base. Proper anchoring is crucial to maintain the vertical alignment of the motor and shaft.

2. Pipe Support: Independent supports for suction and discharge piping are mandatory to eliminate mechanical stress on the pump casing, preventing seal failure.

3. Inlet Conditions: Ensure the suction pipe diameter is equal to or larger than the pump inlet to prevent cavitation.

Maintenance & Troubleshooting:

• No Dry Running: Always prime the pump before starting. Running without liquid will destroy the mechanical seal within seconds.

• Seal Care: When replacing the cartridge-style seal, only use genuine Kaiquan parts. Ensure the seal faces are clean and dry during installation.

• Routine Inspection: Monitor motor vibration and noise levels. For standby units, rotate the pump weekly to ensure grease distribution in the bearings.
