凯泉 125KQL94-44-22/4 安装与维护指南
一、 关键安装注意事项 (Installation Tips)
基础稳固:由于 125KQL 配备 22kW 电机,自重较大。安装基础应坚实,建议浇注混凝土基础并埋设地脚螺栓,以吸收运行时的震动。
管路支撑:泵的进出口管路应设独立支撑,严禁将管路重量直接压在泵体法兰上,否则会导致泵体开裂或电机轴偏摆。
同心度校验:虽然立式管道泵为电机直联,但在安装完毕后仍需手动盘车,检查是否灵活,确保无卡阻现象。
排气灌泵:启动前必须排净泵内空气。严禁在无介质状态下干转,否则会导致 M3N 机械密封瞬间烧毁。
二、 常见问题解答 (FAQ)
Q1:为什么 125KQL94-44-22/4 运行过程中振动较大?
可能原因:地脚螺栓松动、管路支撑不牢固或叶轮内有异物。
解决方法:检查底座固定情况,清理管路过滤器。若振动持续,需检查原厂叶轮是否磨损导致不平衡。
Q2:如何延长机封的使用寿命?
建议:保持输送介质清洁。若介质含有杂质,应加装凯泉原厂外冲洗系统。同时避免泵长期在超低流量工况下运行。
Q3:这款泵可以输送热水吗?
说明:标准配置支持 80℃ 以下水温。若您的工况为 80℃-120℃ 的热水系统,请联系我们更换耐高温原厂机械密封和氟橡胶O型圈。
English Version: Installation & FAQ (Professional Guide)
1. Critical Installation Guidelines
Foundation Support: A solid concrete foundation is recommended for the 22kW motor to minimize operational resonance.
Pipeline Support: Ensure that the weight of the piping is not supported by the pump casing. Independent pipe stands are mandatory.
Pre-starting Check: Always prime the pump (venting air) before starting. Dry running will cause immediate failure of the mechanical seal.
2. Frequently Asked Questions (FAQ)
Q1: What causes excessive vibration in the 125KQL series?
Causes: Loose foundation bolts, lack of pipe support, or debris in the impeller. Kaiquan genuine impellers are dynamically balanced to minimize this risk.
Q2: Can this pump handle high-temperature fluids?
Yes, while standard models handle up to 80°C, the 125KQL can support up to 120°C if equipped with optional high-temperature mechanical seals and O-rings.
Q3: Why choose genuine Kaiquan accessories for repair?
Genuine parts ensure 100% mechanical compatibility and maintain the original energy efficiency (MEI > 0.7) of the pump.
