Precautions for assembly and adjustment of double suction pump:
1. Cleaning and inspection. Before starting the assembly of the double suction split case pump, always make sure that all parts and accessories are cleaned and inspected. Cleaning removes dust, impurities and dirt that may remain during production and transportation before it can affect pump operation. Check individual components for completeness, damage or wear, and compliance with specifications and manufacturer's recommendations.
2. Install bearings and seals correctly. Bearings and seals of double suction split case pumps are critical elements to ensure proper pump operation. During assembly, it is important to follow the manufacturer's recommendations for proper bearing and seal installation. Lubricate bearings and ensure they are in the correct position to reduce wear and friction. Proper seal installation prevents leakage and contamination, ensuring safe fluid transfer.
3. Adjust the gap between the double suction impeller and the pump casing. The gap between the impeller and pump casing of a double-suction pump has a significant impact on pump performance. During assembly, ensure that the gap between the impeller and pump casing meets the manufacturer's requirements. A gap that is too large can result in reduced efficiency, while a gap that is too small can cause friction and damage. Precisely tuned for optimal performance and durability based on manufacturer's recommendations.
4. Calibrate the motor and coupling. If the double suction split case pump is motor driven, proper alignment of the motor and coupling is critical. Make sure the motor is installed in the correct position, aligned with the pump shaft, and the bolts are tightened. Calibration of couplings ensures proper torque and rotational motion are transmitted, preventing vibration and damage caused by imbalance.
5. Conduct operational testing and monitoring. After completing the assembly and adjustment of the double suction split case pump, be sure to perform operational testing and monitoring. Before starting it for the first time, make sure that there are no leaks or loose connections. After starting, carefully observe the operating status of the pump, including vibration, noise, temperature, etc. If there is an abnormality, stop the machine immediately for inspection.
