Structure （結構）

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.

泵主要由泵體、葉輪、電機支架和潛水電機等組成。泵體采用高質量的鑄鐵材料制成，結構堅固耐用，具有卓越的耐腐蝕和抗磨損性能。電機支架采用鋁合金材料制成，重量輕，抗腐蝕性能好。葉輪采用高鉻合金材料制成，具有良好的耐磨性和耐腐蝕性。

Installation and Use （安裝使用）

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. 泵應安裝在硬、平地基上，泵體應固定牢固，以避免運行時出現振動和噪聲。

2. 使用泵之前，應檢查電源電壓是否符合要求。

3. 安裝時要注意電機的旋轉方向，如轉向不正確，應及時調整電源的接線。

4. 使用時，泵應完全浸入水中，水位不應低于泵所示的最小浸入深度。

5. 定期檢查泵的運行狀態、電機的絕緣、機械密封的泄漏及清理泵體，及時更換磨損零件，以確保泵的正常可靠運行。
