The disassembly and installation of a boiler feed water pump is a complex and important task that requires strict adherence to operating procedures. During operation, safety must be prioritized to ensure equipment performance and stability. If there are any uncertainties, it is recommended to consult with professionals.

I. Disassembly Steps

1. Preliminary Preparations: Ensure the boiler feed water pump has completely stopped operating and cooled down. Turn off the relevant power and water sources, and prepare the necessary tools and equipment.

2. Unloading and Transportation: First, disconnect the pipes and cables connected to the feed water pump, then carefully remove the pump from the boiler, ensuring that its components are intact. Afterwards, properly package and label the disassembled components for subsequent installation and identification.

3. Disassembly Process: Disassemble in order from outside to inside. First remove the external components such as the pump casing, end caps, and bearings, then gradually disassemble the internal components such as the impeller, bearings, and seals. Be careful to avoid damaging the components during disassembly.

II. Installation Steps

1. Preliminary Preparations: Ensure the installation site is clean and free of debris, and prepare all necessary tools, parts, and materials. Simultaneously, Confirm that the installation location meets design requirements and facilitates subsequent maintenance and inspection.

2. Installation Base: Construct the base according to the manufacturer's installation requirements. Ensure the base is level and firm, preventing instability due to base problems.

3. Installing the Pump Body: Place the pump body on the base and install it in the reverse order of disassembly. First install the internal components, such as the impeller, bearings, and seals, then install the external components, such as the end cap and casing.

4. Connecting Pipes and Cables: Connect the inlet and outlet pipes and cables according to the design requirements. Ensure that the pipe connections are firm and well-sealed, and that the cable connections are correct.

5. Debugging and Testing: After completion of installation, conduct system debugging and testing. Check the operation of the feed water pump to ensure that its performance meets design requirements.

Precautions:

1. During disassembly and installation, pay attention to safety and avoid injury.

2. Strictly follow the manufacturer's disassembly and installation instructions to avoid equipment damage or performance degradation due to improper operation.

3. During disassembly and installation, properly label and store the components to prevent loss or confusion.

4. After disassembly and installation, conduct a system inspection and test to ensure the normal operation of the feed water pump.
