Structure （结构）

The pump is mainly composed of a pump body, impeller, motor bracket, and submersible motor. The pump body is made of high-quality cast iron, which is sturdy and durable, and has excellent anti-corrosion and anti-wear properties. The motor bracket is made of aluminum alloy, which is light in weight and corrosion-resistant. The impeller is made of high-chromium alloy, which has good wear resistance and corrosion resistance.

泵主要由泵体、叶轮、电机支架和潜水电机等组成。泵体采用高质量的铸铁材料制成，结构坚固耐用，具有卓越的耐腐蚀和抗磨损性能。电机支架采用铝合金材料制成，重量轻，抗腐蚀性能好。叶轮采用高铬合金材料制成，具有良好的耐磨性和耐腐蚀性。

Installation and Use （安装使用）

1. The pump should be installed on a hard and flat foundation, and the pump body should be fixed firmly to avoid vibration and noise during operation.

2. Check the power supply voltage before using the pump to make sure it meets the requirements.

3. Pay attention to the direction of rotation of the motor during installation. If the rotation direction is incorrect, the wiring of the power supply should be adjusted in time.

4. The pump should be completely immersed in water during use, and the water level should not be lower than the minimum immersion depth indicated by the pump.

5. Regularly check the pump’s operation status, the motor’s insulation, and the mechanical seal’s leakage. Clean the pump regularly, and replace the wear parts in time to ensure the normal and reliable operation of the pump.

1. 泵应安装在硬、平地基上，泵体应固定牢固，以避免运行时出现振动和噪声。

2. 使用泵之前，应检查电源电压是否符合要求。

3. 安装时要注意电机的旋转方向，如转向不正确，应及时调整电源的接线。

4. 使用时，泵应完全浸入水中，水位不应低于泵所示的最小浸入深度。

5. 定期检查泵的运行状态、电机的绝缘、机械密封的泄漏及清理泵体，及时更换磨损零件，以确保泵的正常可靠运行。
